Fun fact: Koenigsegg bought the rights for the Motoro Moderni flat-12 and was going to put a Motori Moderni down-tuned 9000 rpm version in the first Koenigsegg. But during development the owner Carlo Chiti died and the company went bankrupt. Koenigsegg later bought all the tooling and stuff in an auction, but the tooling was obsolete with wooden tooling and hand written drawings etc, so they ultimately opted for the Ford Modular V8 instead.

Yeah I'd love a racing series which has just some basic rules for the cars. Something like "Car must fit in X * Y * Z sized box, driver must be in the car, car + driver must weigh at least M kg." And have a budget gap so that some trillion dollar company can't throw a billion € per year into their Formula X team. Also the car should pass a crash test etc. so that crashes are at least somewhat survivable. If the cars are too fast and dangerous, you can always adjust the size, weight and budget limits so that you can't have too big engines or insane parts. F1 has become lame because every time someone invents something new, it gets banned. How can you innovate if everything you can do is already dictated in technical regulations and if you do innovate something, it's deemed illegal or unfair?

I heard a song AbroadInJapan uses a lot and now I see wacky. Coincidence?

I’ve often contemplated how the F1 landscape would look if the rules allowed manufacturers to use whatever form of propulsion they wanted with a cap on fuel amounts and type. The premise would be a race of 25-50 laps with a capped amount for qualifying and race. Those that complete the laps would be ranked by time and those that come up short would be placed according to distance travelled. While I’m sure many would arrive at similar conclusions, it would be cool to return to an era where each manufacturer had varied configurations, cylinder numbers, displacements, and use of turbos/superchargers/hybrid batteries.

Sleeve valve. An ICE engine is at base, an air pump. If the engine restrictions were removed someone would try a liquid cooled sleeve valve engine, like the Napier Sabre engine used in the Hawker Typhoon and Hawker Tempest. The Sabre engine produced 1.36 HP per cubic inch using relatively low octane gasoline (by present standards) and a low compression ratio of 7:1 . A sleeve valve setup had the highest volumetric efficiency of the WW II aircraft engines. With no poppet valves, valve float and binding cannot occur. The complexities of the engine were a problem for front line fighter maintenance, but not such a problem in a race car, where teardown and rebuild is a given. And THEN you had turbocharging!

I used to be an engineer and I would have loved the opportunity to design a completely new type of engine. The things that come to mind that i would experiment with would be, taking your block choice for some simplicity and going two stroke with a typical 4 stroke crankcase and valve design. Use the turbo for expelling exhaust, then continuing to charge the cylinder after the exhaust is flushed. Then push more towards the diesel style by using high pressure direct injection after tdc, may not be feasible but I'm tired and just playing. I would keep the hybrid turbo basics but replace the battery with a vacuum fly wheel. I would also add an additional combustion method for the turbine to speed it up and extract more of its existing potential. Like i said I'm not at my sharpest and just felt like playing and trying to re-live the good old days of conceptualizing before then spending a lot of time trying to figure out why it won't work until reaching a point that it might. Conceptualizing was one of my favorite parts especially with others and trying to see if you have an idea worth continuing to think about.

@@maxjtj31 that's a good question. I am just spit balling at the moment. If I'm not mixing anything up the cylinder actually clears itself quite a lot before the stroke due to the high pressure. So I think to be more clear the energy from the cylinder that would go into driving the turbine side would be mostly at the beginning of exhaust valve opening and it's the heat that drives all the work in the cylinder or the turbine. After that time the compressor would clear the remaining exhaust, if that was even necessary, both intake and exhaust valves would be open so other than friction of back pressures the turbo wouldn't use much energy. We have 10 cylinders contributing to this overlapping each other. I am also pretty sure the actual stroke doesn't contribute anything to the turbine. Once the exhaust valve closes though things will get very different. Not only will you be adding charge but you will be doing it against the up stroke which might be a mistake, maybe it would be better to keep the intake closed until most of the compression stroke is complete. The amount of compression I'm talking about is well above anything that would detonate gasoline, ethanol might help, or diesel. Basically as high a compression as you can possibly get in the cylinder without breaking anything and you will need a very clever means of cooling the compressed air down. Remember part of the system is using a recovered energy method to drive the compressor or compressors just instead of a battery hybrid I suggested a vacuum enclosed fly wheel. Also the turbine will be getting help from fuel being injected and ignited into the exhaust stream before entering the turbine. This turbine(s)/compressor(s) I see as being multi stage more simply a low and high pressure stage. A turbo engine I've joked is a turbine engine with a ridiculously complicated combustion chamber. What I'm trying to push towards here is still having a piston engine which is still important for certain driveability aspects but lean really hard into the jet engine power density side of things. Does that help?

Isn’t each cylinder part of the same pre-turbo manifold system while the exhaust valves are open? I don’t think the turbo would ever decrease the pressure of this system vs not having a turbo at all but I could be wrong. Couple more ideas - freevalve style pneumatic valves - tube feed on top and bottom of valve retainer inside a sealed cylinder - constant air pressure provided by engine pump and single servo per valve that adjust where air pressure is directed - above or below the valve retainer for each valve. Also for the powered turbo (or mug-h or whatever it’s called) - a super capacitor and motor might do the trick. Extremely detailed modulation and pretty much no limits on short term power - no mechanical and friction inefficiencies that a flywheel would have and much less waste than would come from charging and discharging a battery rapidly. Could probably get around 20 Wh/kg with a good bespoke graphene supercap. 150 kW in short burst would probably be enough for the electric turbo, so at 20 Wh/kg that’s 70 kW*seconds/kg. So 1 second of 150 kW per 2 kg of supercap.

@@chuckp6667 something I just thought of as well - you could have a 3rd turbine on the same shaft as the exhaust and intake turbines that creates negative pressure for the point of extracting exhaust gasses. You could have one exhaust valve on each cylinder connected to the main exhaust turbine and the other exhaust valve connected to a separate manifold that connects to the reverse turbine. With the pneumatic valves you could have the valve attached to the traditional turbo open to initially to send energy that way to power the system, then once that exhaust energy is extracted, close that valve and open the valve to the reverse turbo, sucking the rest of the exhaust out, then that one closes and the intake valves open and force the insanely high boost into the cylinder before it’s too far past bottom dead center.

@@maxjtj31 vacuum sealed fly wheels are extremely energy dense and very efficient. This means very high reliability and ease of use and implementation as opposed to just a different type of electrical storage that would still require a motor to use the stored energy. The valves wouldn't just be wide open all the time the exhaust valve would just be open for that amount of time to clear the last bit of exhaust if that is even necessary with the amount of charge that will ultimately be put in the cylinder. I'm pretty sure very large marine 2 strike diesels already use a similar technique. As far as fancy individually controlled valves and intricate systems go, I've heard people talking about these things for a long time but they can't seem to make them reliable. Most of what I'm suggesting doesn't require anything that isn't in some type of mainstream use. This means reliability should be reasonable to achieve because most of the components are already common use either in an engine or other commercial/industrial application. Nothing theoretical or requiring extensive r&d except the need to extremely increase the strength of the engine components. The charge air cooling system would also be challenging. To clarify the turbo components would be designed using jet turbine methods, things like single crystal grown turbines that are able to take heat much in excess of any automotive style turbo. Not much in this design would require the use of new technology, just repurposed existing and proven technology for the need to be reliable. The swept displacement of this engine would be very low. I should have reread what I wrote but when I think I said both valves would be open at the same time, I meant for a very short time, just enough to clear the remaining exhaust products, this is to avoid the exhaust stroke.

hear me out: Boxer-8, 2.0L, titanium internals (crank, rods and pistons), double rotary valves for each piston (also made out of titanium), billet block and head, variable geometry turbo, timing gears and variable valve timing. expect at least 800HP to 1000HP out of this (would probably make much more) and way over 15k RPM redline. plus perfect balance (as it is a Boxer-8) and fewer moving parts because of the rotary valves plus less torque being wasted on opening the valves and no valve float at all. it is not a very complex engine btw, if you want to make it complex take off the timing gears and swap it straight for a little eletric motor that will spin the valves and connect it to the ECU so it will act like a Freevalve. this would be an absolute beast, no need for hybrid motors, but if you want one, go on, add one too. also wouldnt have much turbo lag because of modern tecnology and the ammount of cylinders.

For camshaft tho, I think I have a better idea. Koenigsegg's freevalve is extremely genius, although maybe it might risk malfunctioning, but atleast it works. So instead of the curve of a traditional valve's opening, you get an up-down-up down opening, which means that it can put more air because the camshaft isn't closing after it reaches the peak. It's basically all time peak when open then instantly closes. And that's the first benefit only, then second benefit is, you don't have to worry about valve float because it is controlled by the system. And I'm not done yet, there's a third benefit, which is less parasitic loss. In a traditional engine, power can be less because of parasitic loss because engine has to spin many things. A traditional average sedan engine can have alternator, fuel pump, a/c, power steering, and many more. Now, we really are not gonn aput those in an F1 engine for weight reasons, but camshafts are still heavy, and not only that, but the valve that has to compress the valve springs is a challenge, which requires a lot of force, and results to a loss. Since freevalve doesn't have a camshaft, it reduces the parasitic loss of the engine. Another thing that's beneficial is all about turbos and supercharger. Because this has no rules, we can go for both, because why not? You'll get the best of both worlds, and it basically only takes of for the advantage of having a freevalve, but it's still better to have a supercharger than a traditional camshaft with a supercharger right? That's basically twice the parasitic loss of a supercharged freevalve engine. If not, Bugatti also has the innovation which improves their Chiron W16 over the Veyron W16. Basically, intead of splitting the exhaust to 4, there's only 2 headers and 2 turbos are connected to each. There is a valve for the second turbo so that at low rpm, the valves are closed, and all the exhaust gases goes to the first 2 turbos, which results in less lag, then at high rpm, the valve open and since the first 2 turbos are already spooled up, the engine can easily spool up the last 2. It is extremely effective as it make for a better hp and torque curve for low rpms

Rotaries are technically more reliable than a piston engine, but not durable like one. Like an rx8 expect a rebuild every 90k miles iirc (whereas a piston engine can do 300k), but during that time, the rotary is less likely to develop an issue/broke down due to less moving parts, less complexity.

I wouldn’t discount rotary engines. I think Rob Dahm’s 4 rotor is making upwards of 1500 horsepower in a relatively compact package, so I wonder what F1 engineers could do with a turbo 4 rotor, without the restrictions of using a mix of old Mazda road car parts and off the shelf aftermarket stuff.

The bugatti W16 is technically A VVR16. The engines heritage came from the VR6 on the golf. Then they double it up with two banks of VR6 hence, the W12 in bentleys. Then they thought "lets make the ultimate engine by adding 4 more cylinders!" said those germans.

Toluene powered turbo rotary engines might be an idea because power density. Or, hell, two-strokes. You *might* have a hybrid (supercaps, no charge or discharge limit) and AWD. And active aero, active suspension, traction control, all that. No, boxers are not basically 180 degree V engines. Boxers have opposite piston power strokes happening simultaneously. Which means, the engine pictured at 10:15 is not a boxer.

I was very disappointed not to hear any mention of two-strokes or rotaries, or of fuel technologies (they even did a video on Toluene and other "rocket fuels" a couple years ago), or other banned things like Beryllium alloys or ECU items like "Party Mode". Hell, ECU shenanigans could probably be its own video. The whole conclusion just seems very weird too. I mean, start with the question of how much power the modern F1 chassis can practically use (2000hp? 2500hp? more?) and work backwards from there to find the smallest lightest package that can output that power with a moderately usable powerband and enough reliability to finish the race distance 90% of the time. Instead they started with a couple of things they like... but then wound up with something bigger, heavier, and less efficient, with too much power for the chassis... The more interesting question would be whether we are assuming you are allowing refuelling or not for this theoretical engine. I have to assume given the premise that you would be allowing refuelling and any fuel tank size. At SOME point the fuel usage would become so excessive that the time saved per lap would be outweighed by the extra stops... especially if you're also shredding tires. If you're NOT allowing refuelling, then an MGU-K could be very desirable if the efficiency increase from the MGU-K allows you to save more fuel weight than the weight of the hybrid system.

@@toolbaggers Actually hydrogen has among the worse possible energy densities (energy per unit volume). Even in liquid form it has less than a third the energy density of gasoline. It has the best Specific Density (energy per unit mass), but you would need to tow a blimp behind the car to fuel it, and then you're still going to struggle to make any power out of the engine because you'd only be able to fit a tiny bit of hydrogen into the cylinder. Now, if you don't want to tow a blimp consider this: a 700-bar carbon fibre tank weighs 96kg in order to hold 5kg of hydrogen. So in order to carry the same energy as a 220L (159kg) gasoline tank you would need only 48kg of hydrogen... but 931kg of fuel tanks.

F1 Drivers: so you have chose death

Here in the States, Subarus are well known for their reliability, save for one problem that was fixed in 2013. Prior to 2013 Subaru engines were well known to blow head gaskets. The only chronic problem Subarus have now is related to a lack of maintenance on the part of owners. Subarus will develop oil leaks if... an owner does not change the PCV valve on a regular basis, preferably about every 30,000 miles.

All things considered with weight and aero factored in, I think an inline 6 would be the best F1 engine. My calculations of about 2 liters would have the bore between 95-100mm. The inherent balance and smoothness and simplicity would be ideal for reliability and comfort. The firing order gives a nice torque curve as well. It would actually be very compact, since it would employ a dry sump and the intake would be on the side instead of the top, meaning one side pod for intake air and the other for cooling. Since I believe race cars neeed starter motors for safety, we might as well employ a compact but powerful MGU mainly to flatten the torque curve even more. The engine would rev quite easily to 20,000rpm and sound mentally good being half a v12 with more time between cylinder firings. Look up Honda CBX or Honda Valkyrie exhaust sound to get some idea. In a race car, a capacitor makes a lot of sense for energy storage, but an engineer would have to decide between that and a battery. I think F1 should be closed cockpit like WEC prototypes and employ race spec air condition in the cockpit to keep temps under control so a battery might make more sense. The last idea is up in the air, but imagine ONLY and MGU-H with no exhaust driven turbine ruining sound. And electric compressor, aka and electric centrifugal supercharger to add torque to a 2 liter straight 6.

Or even better their group S engine. Essentially, the intake is coming straight down with 1 turbo on each side. The intake valves are not next to each other but rather across from each other. A correct inlet angle causes a vortex in the cylinder to form, improving efficiency. The 2 exhaust valves are also across from each other, 1 on the left and 1 on the right side of the engine. The packaging becomes not too dissimilar to a V6/V8. It would be a bit taller and longer in the middle, but coke bottling around the turbos gives room for aerodynamics.

The problem with 4 banger/inline engine, they cannot be stuctural like V6 to V12. Since mid 90, the rear of the car is only supported buy the engine and gearbox assembly. Since a V is wide it's quite strong, as opposed as an inline engine way more narrower. It would mean additionnal support in the chassis. In fact Williams made a 1.6 Inline 4 with F1 regulation in mind in early 2010, but FIA then choose V6 instead of inline 4. This engine is on the Jaguar prototype CX-75 (probably tuned down). Twin charger today's means nothing, there were a solution to turbo lag back in '80, since then we found multiple "weight free" solutions to reduce lag.

Supercapacitors don't contain enough nearly enough energy. The formula is E = 0.5 * C * V^2, increasing capacitance doesn't really do anything, and supercapacitors (currently) only work at extremely low voltages so you'd need a crap load of them. Supercapacitors haven't even really approached the point where they can store enough energy to reliably replace the lead acid battery for your starter motor. Nothing "stores" energy better then combustible fuel, from a purely theoretical standpoint a lithium battery will never beat the energy density of an equal volume of gasoline. A battery needs a conductive anode (copper / lead), an electrolyte (polymer / sulfuric acid), a conductive cathode (lithium / lead), and finally an insulator (plastic / paper). With a combustible fuel you only need a fuel (gasoline / methanol), and an oxygen (air / NOS / LOX). Anything someone says there's a revolutionary new EV tech that will beat ICE on range, they're lying and that's why - it is theoretically impossible to have a battery that stores more energy then a combustible fuel.

6:25 The Comprex supercharger is a genius design. It's basically a hollow pipe with 2-stroke-like gas ports, with a spinning airtight paddle wheel inside. The exhaust goes into the drum on one end, and pushes the air directly into the intake on the other end, and the spinning motion makes the exhaust gases miss the intake manifold port right as they approach it. The gas is reflected into the opposite direction where there's an open exhaust port, and on the same side soon opens the fresh air port that sucks in the air as the escaping exhaust gases leave behind vacuum.

No rules sounds just right to me. It would make F1 interesting again. One thing that isn't being discussed here is the extra weight and packaging size (in the case of ICE mills) of the necessary larger fuel tank and stronger transmission. Every change introduces necessary compromises. And the same no rule "rule" should be applied to the wheel/tire packages. Imagine if Pirelli weren't dictating to EVERYONE.

There was a time when F1 was full of different concepts, the golden age of F1. Today's F1: now you're too fast, now you're too slow, safety first, the track is too dangerous, not city racing - a family friendly show.

No tech limits would get me interested in racing again. Anyway, I'm an engineer but not in the automotive space.

They spin at high speeds making mechanical gearboxes complex. Meanwhile, electric motors are great at torque - this is why most trains are diesel electric rather than using mechanical transmissions. Anyway, supercaps can charge and discharge much faster than any battery, allowing you to decelerate into a corner, fully charge the supercaps, then throw down gobs of torque - all while keeping your turbine at constant speed providing baseline power for the vehicle. I also think a similar design (but using batteries) makes sense for consumer vehicles.

Imagine a 6 bank (3 each side) rotary Ran on hydrogen - Each rotor being very lean stoic with. A evinrude e-tec injector, In the air intake! Really lean hydrogen And then a mahle jet ignition direct just 20 degrees after the inlets.. creating a combustion ignition in a instant for a better more complete combustion! Ran on a single turbo with a power take off on the turbo to absorb power into a power bank that ran at a high tick over A slipper clutch so that it absorbed power and all your breaking would be done under brake pedal and no engine breaking! But giving you a huge torque driving that single turbo our of the corners! 😮

Terrible design, great novelty for the 1970's, but vastly inferior to current technology. Inefficient, pollution of the 2-stroke like oiled combustion chamber is dirty. Thermally a complete mess, too many large critical flat surfaces subjected to uneven heat at high temps, low compression, inefficient combustion chamber design. I could go on, but why?

Scott explains complex concepts so well!!! Would love to see a video explaining the difference between current F1 regs vs 2026 regs.

for hybrid setup, i think supercapacitor should be considered over traditional battery since it just need to store little amount of power to accomodate the lag, while it can dump a huge amount of current that would produce really high torque

It took half the video to find out v12 is the preferred configuration

Toluene.... Played a bit with it a few years ago. Got a tune with 10% mix with petrol... Lots of timing. Its Fun! 😅

In a wonderful bout of irony, I stumbled on this video whilst sitting in my cubicle at the Northrop test site where that shuttle rocket booster test took place. Cool vid!

Fun fact.. i designed the lotus in the beginning when i was about 8.. the initial design was made out a small pine wood block and we used to race them against each other down a handbuilt wooden sloped track. We weren't even allowed engine back then. Rules were super strict. We instead used lead weights to try and go faster. That was the only goal. Go faster.

Hands up those who recognised Jackstand Jimmy! 😄

"there's no replacement for displacement" "actually, there is: turbo"

Nobody mentioned the gas turbine engine. See a 4 stroke only produces power 25% of the time, a 2 stroke 50%, a 1 stroke 100%. If you want a lot of power, the best way to go is a multistage gas turbine or rocket engine with a consistent 100% rotational output, then everything becomes balanced, almost no bearing drag from crankshaft torque, and no force wasted on moving valves up and down. When I say a lot of power, I'm talking well over 5,000HP for something you can fit in your car. Look at the M1 Abrams for instance, the engine in that thing puts out 1500HP stock for something that's smaller then some big block V8s that can barely do 1500HP after being built and tuned. It was built in the 70s and was made to reliably run on anything from dirty piss to jet fuel, while in a closed metal box with zero airflow in a 100 degree desert, not to make power. Piston engines are *not* suited for high power output, the only reason we use them is that they're cheap and really easy to mass produce. The forces inside piston engines do nothing but fight you the whole way from combustion to the crankshaft, any weight being flung up and down is a net energy loss. A turbine creates force in a purely rotational moment, the only power lost is from the compression stage and the bearing loss, which in a turbine is so small you can spin the thing by hand and it'll sit there and keep spinning for the next few seconds, try doing that with a piston engine.

spot on - Abrams tank turbine is tuned for field reliability and longevity and look at what it can do, if we look at single use type high performance turbines we start to see things like the Turbo Pumps on rocket engines, Space Shuttle for example, 85,000HP in a package not much bigger than a large V8....if that tech could be scaled down who knows where it would go.

I'm pretty sure it would be a series turbine-electric like they use on trains. Jets don't like running at low or variable RPM, but if they are just turning a generator, then the electric motors on the other side can handle all of that gracefully. Then add a battery in there to add some oomph coming out of corners. The only remaining question is if you can make a good, small gas turbine engine.

@@motominded5275 so... I have done gas turbine (jet and rocket engine) design classes before, and if I remember anything from them, things don't usually "just scale up" or "just scale down". There are various problems with that, mostly relating to blade working area, local speed of sound, and Reynolds numbers. Furthermore, the size of an ECU doesn't change much whether the engine makes 500 or 5000 horsepower; that means that it's going to hurt the 500 HP engine's weight and size disproportionately compared to the 5000 HP one.

@@JMurph2015 yeah - it doesn't scale 1:1, but it certainly scales.....an even more extreme example is SSME (Space Shuttle Main Engine), it's turbopump is rated at something like 85,000HP and the size people quote is "about the size of a car engine", who knows in reality how it could be packaged but it's a single use TP that could be scaled down to produce thousands if not tens of thousands HP in a smaller form function than we currently see on the shuttle. Std. aircraft turbines don't scale well since they are designed for thousands of hours of use and have to have impeccable reliability ratings over those thousands of hours unlike a rocket that is single use and rebuild, more sim. to a F1 engine. Reality it would be somewhere in between rocket TP and a aircraft Turbine if custom manuf. no rules by a F1 team, the technology, material science and components are out there to make 85,000HP, power to weight is off the charts.....power to fuel consumption, who knows....but with a lighter engine you can add more fuel, but how much power do you really need? I can't imagine over 2-3k would be useful....seems to me you start to get into the realm of prioritizing packaging constraints, aero, balance, reliability, fuel consumption and all the other things that become more important as long as you have enough HP.

That was my First thought too, but after calculating, the current Tech doesn't deliver yet. Imagine two 800hp e-motors at a total of 80kg. Then you need 1600hp of electric Power. Split that to an 800 HP Generator and an 800hp battery (assuming 100% charging efficiency). LIPO batteries are at a Power density(not Energy density) up to 430W/kg. So you need a 140 kg battery to prevent voltage collapsing or overheating. But that's without cooling. So the package already weighs more than a current F1 engine + Gearbox but you still need an 800HP Generator.

@@geoghs02 The highest discharge Rates of LIPO batteries are at 85C. That means they completely discharge in less than a Minute. At that point Energy density gets more important than power density and I think LIPO batteries easily beat supercaps at that. So yeah, you need less supercaps for 800Hp but those wouldn't last a long straight and once you have enough of them to last a long straight they are heavier than the lipos were. Btw: That AMZ Mythen record EV that accelerated to 100 km/h in less than a second was also powered by bespoke LIPO batteries and not by supercaps and im pretty sure they know more about this and would have had the means to do otherwise. So maybe supercaps are a bit of a myth.

Really Interesting look at what could be possible. I have often wondered about the solutions to more power/less weight if the rule book were to be dumped. One suggestion though, you really need an microphone isolation mount, especially one that is not connected to the desk - every time your elbows or arms touched the table there was a very audible "thump" transmitted to the mic. Drove me nuts! Ok, drove me more nuts. Cheers, Susi.

On the topic of 'true W engines' at 12:28 , I like to call the Bugatti engines a WR setup, since their W16 was based on Volkswagen's VR engines.

The H-16 (made up of the internals of two 1.5 liter V-8) sounded pretty interesting too. Kind of an unreliable "boat anchor" but Jimmy Clark did win a single race with one.

This would make the sport more interesting.

One thing I missed from this video is the rule framework taken into consideration outside of the engines. Because with current rules on fuel flow and no refueling, the current engines are very very close to what's theoretically possible in terms of power output. Maybe a tad more displacement like 2 or 2.5 liters, slightly less boost and slightly lower rpm would be advantageous to increase thermal efficiency, but that's about it. IF we can use more fuel (but no refueling), we exchange fuel efficiency for more power at similar weight i.e. ditch the hybrid stuff, enlarge displacement and add boost. IF we can also use the engine aerodynamically, we blow insane amounts of fuel through it to create an artificial fan car that gains 5 seconds a lap in slow corners.

How about a miniature deltic configuration? Very compact with lots of pistons, and 2 stroke so double the power strokes.

The fun thing about power is only so much can be reliably put down. This opens up really ridiculous ideas, like a stock block, pushrod LS V8. You can cheaply get 1,000hp out of a turbo LS and it will last miles and miles, with better economy than you'd imagine.

I'm utterly shocked that you guys took my proposal seriously and challenged it. Wow. Just wow. 😮

At 8;08, I believe that's the Fiat A.s.6. It powered the Macchi Castoldi MC72 float plane in the 1930s.to a speed of about 440 mph. Not bad for a plane with twin floats, open cockpit and bracing wires. Oh yes, the horsepower was in the 3,000 range. After about ninety years, that record still stands!

Basically, a turbo gives you a larger displacement (on demand) without increasing the rotational inertia nor engine weight. But -- there is a relationship between the temp delta of the fuel-air mixture vs the temp (obviously avoiding the stoichiometric maxim via rich) ... as that gives you the pressure, which is the work available. People just do NOT realize how hard it is to turn a crank manually, and the amount of horsepower lost to avoid float at the given redline of the engine. But I didn't realize that the pneumatic valves in F1 engines were still actuated by cams instead of computers. I ALWAYS used to explain turbos as increasing the displacement with each atmosphere of pressure. Usually, you're in VACUUM with NA engines BTW. Bc it's that vacuum that sucks the air in. Just some of the obvious reasons engines are called ... air pumps.
