Nice and informative video as usual, thank you! Would love to see a video with different trigger setup offerings. Now factory installed Nissan 360 optical CAS is a very good system in theory, it gives a very precise measurement provided that - ECU has enough computation power or a dedicated trigger preprocessing unit - there is no play anywhere in the entire assembly (disk to intermediate shaft, sensor to disk, intermediate shaft to camshaft) In practice though it is affected by harmonics and can misread cam position if there is even a small play anywhere in the assembly. Would like to know your opinion on the factory system and on alternatives like AEM CAS disk, crank trigger setups and what rev level makes them preferable to the factory system, and how it would affect fuel phasing, and whether using an aftermarket triggering system would imply switching from sequential to batch fire fueling.

@@hermanurriola138 Hey Herman, appreciate for response! Would like to use this opportunity and say thank you for the videos where you meticulously test blocks' geometry and hardness and enlighten us on their construction, I've learned a lot from them and from your other videos as well. Regarding factory CAS - I saw that Haltech video and honestly I'm not entirely convinced that factory CAS is all that bad. Replacing CAS with 1-tooth sync sensor doesn't eliminate belt stretch or wobble, it basically roughens signal precision 30-fold and then relies on ECU to do its math on injection and ignition phasing. From that point on it's just the matter of how much "ticks" ECU internal clock does between cam sync and crank tooth, how fast the processor is and what heuristics/algorithms it uses to approximate timing. It's still not exactly precise, particularly when the engine is accelerating or decelerating at a fast rate. I'm also not entirely convinced that power levels are a good reference when CAS replacement is being pondered. True, on high-boost application 4 degrees of error on spark advance could cost you an engine and 4 degrees of retardation could cost you lost HP and overheated exhaust valves, but both are consequences, not causes of the initial problem - the belt stretch or to be more precise inconsistency of connection between cam and crank position. I may be wrong, but I'd expect belt stretch to occur more readily on an engine that has lighter rotating assembly with 300kw than on a 500kw engine with heavy pistons, rods and crank since the former would accelerate faster and therefore stretch the belt more. I'd also expect it to be dependent more on the level the rev limiter is set to. Power level reference also doesn't explain why some people have problems tuning off of factory CAS at 280kw/7500 RPM, while others are running without any trouble at 400kw/8500 RPM. I'm also not sure that crank positioning is the major thing that should be taken into account with cam signal left solely for sync purpose. You've raised a very good point why it is necessary for 4-stroke engines to have a cam sync signal in order to utilize proper sequential fuelling and ignition, but I'd say that defining all four strokes solely based on crank position would be a simplification. A more accurate statement would be that - intake stroke ends and compression stroke starts when intake valves are fully closed and ends a little before pressure wave from ignition starts to push on the piston - power stroke starts with the ignition and ends when exhaust valves open - exhaust stroke starts when exhaust valves open when exhaust stroke ends and intake stroke starts is dependent on cam setup, valve overlap, intake and exhaust flow harmonics, boost and exhaust gas pressure and a lot of other things, which are specific for each engine configuration and must be tuned for. I'm writing those obvious things to make a point that most of events that are important from engine management POV are more dependent on camshaft position than on crank position. In that regard CAS on its own does a very good job at providing an ECU with all the necessary info for proper engine management. Factors like belt stretch appear to me to be a constant you can tune for provided that you use same belt manufacturer and model all the time and that belt tensioner and idler are doing their job. This leaves the aspect of how tightly and solidly the factory CAS is attached to its driving camshaft. Obviously if there is a play in the place where one is connected to the other, no amount of tuning and belt tensioning would result in accurate engine management. Unfortunately, there was no info in that video answering that question, but I guess that is to be expected since cam sync plate you offer is mounted solidly on the cam gear. Factory CAS is really a very smart and ingenious assembly that makes ECU programming very straightforward - since it has 360 cuts on its outer ring, all ECU has to do once long sync cutout begins is to count small cuts until it ends. When sync cutout ends, it stops counting and evaluates that number and uses it as an index to access certain data tables. By doing that it learns exactly what cylinder it has to fuel and/or fire. There is no time consuming operations for ECU, no divisions, just a very basic increment followed by a branch and memory access. What's bad about it is that it requires very direct and solid connection to its driving camshaft, which may not be the case on older RBs. Also if there are harmonics when the ECU counts small cuts, it can become inaccurate and count 2-4-6 extra cuts, if one small cut flies back and forth in front of the optical detector within large cutout in front of the other, and that can spoil sync detection big time. With the factory CAS the tuner must also be absolutely certain that ECU receives a good clean signal from the CAS, that wiring is in good shape and that there is no electromagnetic interference anywhere between CAS and ECU - since at 8000 RPM the ECU has to pick up a square-wave signal at a rate of 24 000 pulses per second from the 360-cut factory CAS disk. This can be easily spoiled by a broken wire. In my own point of view a good and inexpensive solution to fix factory CAS inconsistency would be to manufacture (laser cut?) a replacement disk with larger and fewer cuts (like AEM replacement disk, but it has a bit too few cuts IMO). It basically does the same thing as split crank-cam 24+1 tooth setup - reduces amount of signals produced by CAS (but not 30-fold), makes them less sensitive to EM-interference and less demanding to calculating power of the ECU, but unlike split crank-cam setup it wouldn't require rewiring and replacing crank belt gear. This solution would be aimed at the consumers who already use an aftermarket ECU, but are not interested in all-out high-RPM race builds.

Great videos and very informational! My next rb build will be with prp parts

you can also run a cable ( or shaft, just cable style is more common to see looks like a flexible rotary drermal tool adapter ) drive to the back of the car were the main fuel tank is, like a lot of turbocharged V-8 do and saves the what of a "surge tank" but for a streetcar it's still recommend to have a priming pump ( i should still should start without it. just might be hard starting ) just to get all of the air out of the lines and on start up ideally having say 60-psi after its running and the mechanical pumps up to 60ish then shut off the electric pump

For the last 100 years they were mechanical fuel pumps, but the only issue i see is that again, you still have to et someone to replace the current electrical system and then run the mechanical system so most of the cars which have multi electrical fuel pumps have already spent the money ,why someone has not made a better electrical system is beyond me, but still good to see someone re inventing the wheel with better products, soon they will have a better electrical system and simpler system as well to compete? Just like Craig Davis electric Water pumps and not mechanical ? So basically its a crank driven fuel pump or cam driven, just like the older dizzy's and mechanical fuel pumps on the older fords and holdens. :)

He was talking about the surge tank being up front. I don't know what motor your running but I'm assuming you don't have belt driven cams to run the pump from and that's why you've got a belt driven pump off the crank pulley with the cable keeping it close to your surge...…..Same principle just different ways of keeping the mech pump close to its source to minimize cavitation etc.

Guys, would you do a CRANKSHAFT comparison video of RB25/26/30 vs 1/2JZ???? It would be very interesting to see the material and all the journal diameters!?

All the new direct injection petrol engines have a mechanical fuel pump. Also correct me if I'm wrong but I believe the Gibson R32 GTR did have a mechanical fuel pump but I don't think it had a fuel pressure regulator so the fuel pressure increased with rpm not manifold pressure. I could be totally wrong I just might not have seen it.

700-800 thousand hp? Crikey! Na jokes. I’m all for fuel/water/oil pump,alternatives. Or any alternatives that challenge the status quo... (electric assisted driveling es with power regeneration abilities on braking ((Nio EP9)) electric assist turbos, composite materials for heat regulation, synthetic and bio fuel mixtures, low drag coefficient targets as well as power to weight targets, and many more, more ‘out there’ alternatives) Currently considering an auxiliary electric oil pump and bits for my turbocharger set up on my street driven, ‘weekend’ car... I wonder why oil lubrication systems can’t use a regulated system to maintain adequate oil pressure to bottom end but supplies only the oil supply the rest of the system can handle at any given rpm, this would also allow for a ‘pre-lube’ function to run along side the fuel pressure priming system. Even if the system is a basic one and merely cuts the ignition for the first few revolutions to get oil pressure up before firing. Although a stand-alone, electric pre-lube pump would be ideal and could have a solenoid to divert oil only through the turbo system and take over oil supply duties on shutdowns. Not required on track driven cars but bloody handy for cars that have to refuel at local servos or finish their journey in a confined public space like an underground car park at woolies.... Also can be a bit obnoxious to others at certain destinations Ie; near dwellings where people’s young children may have finally been put too sleep. Or to your neighbors when you get home at 3am.... Any thoughts or advice?

Great knowledge explained well 👌🏼

Hang on - the lift pump STILL needs to be able to meet the maximum fuel flow of the mechanical pump, and a little extra to ensure the header is kept full, and have enough pressure to ensure it is pumped through the restrictive lines at that volume rate? I REALLY doubt the OEM setup will be anywhere near managing that and higher power installations will potentially need the whole electrical wiring, pump(s) and lines uprated anyway? However, I could very well be mistaken and would be interested in feedback either way, for different applications?

@@Karpo1986 I would remind you - the mechanical pump is roughly proportional to rpm, not load, so the lift/prime pump generally needs to exceed that flow, especially if the return is to the tank. While flow is increased, and current draw reduced, with the reduced pumping head, there is still some head and it is VERY unlikely an OEM will free-flow enough to feed a significant power increase. IF the pump vacuum head is sufficient, taking into account the launch 'G' and fuel temperature - lower pressure in pump feed line and increasing temperature increases the risk of fuel vapourisation* (boiling) in the line which is worse with alcohol containing fuels, I would even look at a pure mechanical system with LARGE bore lines/hoses and fittings. *On that are you Aussie chaps running fuel coolers - they are not uncommon for carb' cars at high ambient temperatures?

In theory it would, but you still have a fuel pressure regulator in the system that dictates fuel pressure. So no, the fuel pressure will still be controlled by the FPR. The fact that the fuel pump speed is reliant on engine speed is a good thing, because it means you aren't circulating a shit ton of fuel that you don't need whilst not on the throttle hard.

@noxious89123

5 жыл бұрын

No, a direct injection engine NEEDS a HPFP. You can't run it on a regular 3~ bar fuel system. They require such high pressure because you're squirting fuel directly into the combustion chamber, where the pressure is massive. If the fuel wasn't at a higher pressure, you'd just end up forcing intake charge air into the fuel system. Pumaspeed have some options, with a Bosch Motorsport HPFP being the "best", but it costs a lot. To be honest, changing a camshaft really isn't a big deal, so I'd just do it...

khaim5 b if you’re unable to spend 2k this anit for you regular port injection aftermarket injectors and pumps are 1500-2500 all together also I doubt tffs developed the pump xdi is a ex Bosch engineer for common rail fuel injection.

Just run a belt driven setup if you cant find a kit.

Simple is best

Really ? Why you still not make videos on the tt that you bought?

ClutchkickPJ this doesn’t answer my question

My notifications have betrayed me.😤

I thought so long as the mechanical pump isn't modified further it was legal and didn't even need a certificate so long as it's secured, supported and shielded. 😕😕 That's in their rules and I quote: "All components used are unmodified." So unless Hermann is hitting the pump with a Dremel, I don't know what the problem is from the governments view? 🤔🤔🤔

I'm actually qualified as a VSCCS engineer, and as its not OEM it needs a certificate, not saying that cant be obtained, but it looks far from standard so its a little tricky, not that a police officer would know what he is looking at.

@@hermanurriola138 Thanks for the clarification Hermann. I'm looking at it from a legal standpoint as the governments terminology allows a loophole that could be exploited, like using disconnectable nitrous bottles back in the day when they introuduced the ban on the street. They make no mention of having to use OEM parts and LM 1.1 even states it as "alternative fuel pumps" with zero clarification through the regulations to whether it must be OEM or even whether it is an electrical or mechanical type. Once again, thanks for the reply Hermann. 👍

Your alternator does become an issue sir more amps better whether your using 6 pumps or not.

Lol watch the hoonigans videos where the guy brings old chevy with stroker motor and he said i have a mechanical fuel pump because it never breaks and car is making 2000/3000hp something like that .... And the moment he started his car ..guess what ..fuel pump broke 😂😂😂😂😂😂
