​@@volvo09 all you would have to do is put a commercial jet air starters intake to the cars exhaust. However the jet air starter would be choked by the car and would probably hurt something in the car.

There needed to be an air seal between the hood and the air intake. That much gap was allowing the wind to blow around the air intake instead of building any kind of pressure. There should have been some kind of a gasket between the two, maybe a foam donut or something. If you brought the blue intake hose through the hood, you could seal around that with some duct tape.

Yeah the mounting holes on the scoop and the gaps between the scoop and the hood and intake pipe are a big issue. The idea would be to take in large amount of air, while compressing it down through a smaller diameter opening, which creates pressure and accelerates the airflow. As the scoop was basically a funnel, it would had needed to be airtight. No holes and a seal between the scoop and the hood. And we never really saw if there was a seal between the hole in the hood and the intake pipe, if not, the whole scoop would had been pointless. But as it had holes and no airtight seal, they were basically just blowing air around, but not building up any pressure

@@SwapBlogRU If it was properly sealed there should have been a gasket of some kind on the hood and there would have been a pan on/under the plumbing the MAF was in before they put the screen over it. Additionally, 0 to any speed really isn't relevant to ram air intakes. There's little effect until at least 30 mph. So roll on testing would have been more representative. Granted, the amount of drag a scoop that size will cause will outweigh the benefits and without a seal, most of that air is just being funneled under the car through the engine bay.

I figured out what is wrong. The thumbnail shows a red hood scoop. But the tests were done without the racing red paint.

I mean it's more for looks than anything. The tiny amount of boost they come with doesn't really need an intercooler.

so you took a turbo charged motor and made it naturally aspirated... The scoop on the subi is for the intercooler. To cool it cus its a top mount. To get better performance place a front mounted intercooler and use the hood scoop into the turbo inlet. Also .5 bsr is around 7 psi so a few holes in the wastegate line will increase boost pressure (old school way lol)

You can't put the MAF in turbulent airflow like that, not to mention the housing you put it in was much larger than what it was tuned for (big no-no). The engine was running so poorly because it was running really, really lean. Really, you would have been better off just leaving it out.

The point is a turbo car computer and sensors are built to measure and adapt to pressurized air. A naturally aspirated car can only go up to 1 ATM and will lean out after. So you compare the car power output running at slow speeds vs high speeds. It doesn't matter that it's slower than stock, you're measuring the difference at speeds. That of course won't help their no seal intake design though.

Removing the turbo was your mistake

The ram only works at higher speeds. Cant do proper testing with it on lower speeds.

i like that your channel is working on other cars besides Ladas now. It is a much needed refresher

I did this to my tiny engine, can confirm the effect kicks in at 80km/h, wasn't struggling uphill anymore.

There is high-pressure air just above the bonnet and low pressure air 5 - 10 cm above the bonnet, you need high pressure air. So the stock scoop is in the high-pressure range and the make shift scoop is way above the high pressure into low pressure which is why its not boosting, the big scoop will have turbulent air inside and not only that it will have big drag also. If you had lots of smaller scoops on the bonnet leading into the hole it will make for better ram air. This is why fast cars have scoops on the sides and top of the car to get the high pressure air running along the body.

"We disabled the turbo, now the air has a massive restriction sucking air in the blocked intake, the ECU probably went into limp home mode, but hey guys on the 4th run if I'm learning to modulate the pedal, I can feel it picking up."

Also check the scoop is airtight. You may have air pressure leaking out between the bolted panels. For an unobstructed view of the road, use a transparent scoop, made as one piece.

The C6R Le Mans corvette would generate ~15kPa of positive pressure upstream of the restrictors @ 185mph on the Mulsanne. When this was simulated on the dyno, it was good for nearly 75hp

It will cause more air drag.

Times got better with multiple runs because the computer learned and adjusted as much as it could.

I played with these for years. the only thing that kicked the n/a into gear was perfect timed cams, symmetrical stainless exhaust, a huge throttle bore...and hovering 11 to 1 static compression...and a timing curve to work through the flat 4 flat spot.(you gurus know what I mean) Makes the turbo more appealing doesn't it.

Whatever power games you get you're going to lose by aerodynamic obstruction LOL

This would be better suited to a normally aspirated car that has also had bigger injectors (to help the ECU inject more fuel in when air pressure increases). Also, there is a HUGE gap between hood scoop/hood and air intake. To do a 'Ram Air' type design, you NEED a fully sealed intake (as you got on Kawasaki's legendary ZZR1100/600 motorbikes, and all other 'Ram Air' designed engine air intakes since. It's no good having all that air collected, channeled down into a smaller and smaller area for it to then flow out before it reaches the inlet manifold. Ideally you'd want a wide mouthed 'Horn'/'Trumpet' design that squashes the large amount of air into a smooth unobstructed tube that reduces into a smaller and smaller area so that the air pressure increases as it enters the engine, like a natural 'Turbo'/'Supercharger' (the higher the vehicle speed, the higher the air pressure at front of vehicle). Also, collecting air into the wide mouthed 'Trumpet' inlet should ideally be where air pressure is highest, ie around the front bumper/grill area. 🤔😏 Maybe a future project - 'Ram Air' Lada? (Because even the old BUT FAST ZZR1100's were carburetta fed) 🤔😏 😎🇬🇧

Try boosting the intercooler with CO2 ice, or feeding liquid air to the engine, carefully of course and adjust the Lada carburetor / Subaru injectors of course for such massive increase in oxygen. If the oxygen sensor even can handle that.

I love how they’re using a 1/800 special edition car for this 🤙 very cool test

If this idea is what I think it is (ram jets for cars?). It cannot work with this test. Ram jets needs sufficient speed before it works properly (around 800km/h I think). This is when the air intake supersedes the drag. So maybe test it but not 0-100kmh instead 100-200kmh. 🧐

Great videos guys, how about trying replacement fluid for the brakes like water or maybe something else oil

This has almost no way to control the flow other than driving speed which changes. Then you have added a HUGE drag coefficient.

The ECU is still on standard setting. What do you expect then?

Whoop! I owned a Forester STI when I lived in Japan. Really fun car, same body style, I miss my SFSTI too fun .. Bonneville Salt Flats with that big old hood scoop might be useful ..

Prediction. It won't work as well as a turbo. A larger scoop will have little effect over a certain size. It just makes drag. Pressure boost at most car speeds is minimal. Aircraft are another matter.

make a piston head out of a meteorite! lots of them are mostly composed of iron.

Run a roof scoop the entire length of the car tapering smaller towards the intake pipe then run it to the MAF right before the manifold. This should create a rushing and pressurized air stream

That is a major improvement to its appearance.

Make a funnel between the scoop and the maf sensor. the air will smooth out with no turbulence

Amazing content, i would love if you tried linking a compressor to an engine

👌🤣👍this guy’s never cease to amaze us with their insane automotive experiments!

A bumper scoop works just as well, but it picks up some dirt and is more aerodynamically sound.

Looks clean

Beautiful car though! Wish we had that variant in the US. But I think we need a do over G54 with a seal between the intake and the hood. Not that it would matter that much without the turbo. But it would matter

Did this 25 years ago to a vw golf 1600cc above 140kph I'd had more power than the gti version plus my top speed was way higher too and everyone thought I was mad. Although my scoop was in the grill and not on the bonnet/hood.

The cars ECU is probably freaking out going from turbo to N/A.

You should definitely try this again but with an N/A car. I think you would see improved results over stock power :)

a thing never done : Step 1 : take a car, go to the scrapyard, put a small camera in it, put the car into a baller, compact it, show us the interior while the thing bein compacted. Step2 : Unfold that car and make it run and drive !

Pull a trailer with 20 Shop Vacs running on a generator, then bring the piping to the front of the car from the exhaust ports of the shop vacs, see how much boost you would get, then try sucking the exhaust and compare the power.

can you get a corolla box type then do everything on it. like maxed out for racing?

Taking the maf out of a 2.75 inch pipe and installing it in a 4 inch one is surefire way to make it run like absolute crap. At least seal the scoop to the pipe. Would be cool to see!

Why didn’t you test the hood scoop with the turbo still hooked up? The engine is tuned for a turbo…..you’d have to be going 300 mph to somewhat duplicate the air ramming down that hood scoop vs a turbo!

You should have done a test with the turbo fully connected and giant scoop to compare it to the stock performance.

Should have done this with a naturally aspirated engine. Turbos gonna do what the turbos gonna do.

This is awesome!!!!!

Cars ECM will not allow engine to take in more air instead it will slow down the engine to make it run as normal as possible you have to tune the ECM to allow for more fuel

They did that already

You need your scoop full with of the car. Like ram jet, it needs at least 200 MPH to work.

overfuelling (ECU is fuel mapped for the turbo) and exhaust restriction (the turbo) is bound to make it slower than stock, no matter what you do, with that particular car.

what every subaru needs. scooby fanbois get your hood scoop from this man.

Am so excited to see this car.

This will work to some extend but not with a scoup, they need a venturi, a giant funnel that is connected to the intake with a sealed joint, this open pipe config is totally inefficient.

That enormous intake will indeed scoop air, and will surely block's your vision!

What if you made an air scoop that covers the roof with a massive silicone pipe going through the cockpit into the intake?? Bet you get cleaner colder air up ther and it'll partially act as a spoiler to bob the whole thing down 🤙

Anyone who ever blew an intercooler pipe off knew how this test would go

Vlad can turn water into wine

El ram air no funciona así, en realidad según lo hacéis la presión es menor, el ram air funciona con unas tomas -entradas pequeñas que se unen en un conducto mas grande, en una caja mas grande, y es en esa cámara, caja, conducto mucho mas grande que la toma donde hay mas presión, lo hacéis al revés, aparte para hacer el experimento lo mejor es un coche atmosférico. Espero lo podáis traducir, y realizar el experimento siguiendo la teoría física correcta.

the Drag the scoop is creating 4 times more drag than benefits... =P

This is awesome 😂😂😂 but will slow you down with all that wind catching it 😂

How about air conditioning for the intake charge or having the intercooler exposed to airflow cooled by dry ice?

It is very hard to get an air scope tuned properly.

you should try on a NA engine from the factory and o 50-150 or some speeds where there is a pressure.

You should be able to have a few psi of boost at the inlet of the turbo

I wounder if they know that they are over spinning the turbo by leaving the inlet disconnected. This is how I killed a turbo on a build of mine (was driving it N/A to get the base map right without boost, killed the turbos bearings)

i am not shure the size of the turbo and engine can handle that much air anyways, you would need a massive engine and a massive turbo to be able to use that much air. Apart from its not entirely sealed, alot of air is escaping the scoop.

Try a parachute next time rather than an engine

I wonder if an NACA shaped duct would get better pressure.

The scoop ideas wonderful but you have it too far back on the hood. The inlet needs to be further out in front of the car otherwise the front of the car won’t allow enough air to get to the intake. The nose of the car will push too much air away.

That thing flys for real wheels off the ground like a beetle that hasn't been squatted at 100 mph. Don't move you change the center of gravity😮😅

Awesome content. This is well known method in boosting horsepower via the ram air scoops in Japanese sport motorcycles.

I thought the job of that scoop was to cool the intercooler? I owned a few of these including a prodrive version and an imported stb version.

i think it's a little bit to....small It can be used as a sail but it needs to be bigger...yes because right now it's more like adding a big wall pulled by the car, and yes air can get into the engine but the scoop is unable to pressurise the air and to inject it into the engine

You unhooked the charge pipe on a turbo car? Good way to destroy a turbo making it over spin. Also as others said it needs to be sealed to even work. We know this works based on drag racers using this method.

So the hot side of the turbo is still getting the exhaust air? Its working to turn that turbine, getting none of the benefits. The ECU is probably taking a shit and just trying to get you home, do it with a NA car.

It would be interesting to use a tesla valve as a scoop.

such a nice forester tooo engine clapped but dam the body is so mint

Put a carburettor on the front of a big turbo to increase horse power.

Is anyone talking about the exhaust back pressure since it’s still plumbed to the turbo? One won’t work well without the other

Have you guys ever put an engine upside down into a lada? I know it is off topic, but..

I was expecting John McClane to pop out of the front holding a lighter 😄

You took the turbo off. The ecu has a fuel map dependant on air flow. If you make it naturally aspirated and just have atmospheric pressure, the car reaponds by delivering less fuel, and then you have a massive decrease in horsepower. This was never going to work as a performance boost.

What happen if you put a motorcycle engine in the trunk and have it rep to 160 mph or more and attachment it to the driver wheel tranmission. When put on neutral the motorcycle engine will take over. Lock on the neutral gear at 160 mph for boost. Can you make a video for that.
