Thought I'd share this engine with you...

442ci General Motors based OHV V8

- no gaskets, just heat expanding O-rings

- extesive use of titanium.

- fluid dynamic crank to cut through the oil easier at speed

- turbos similar spec to what is found on Indy cars

Capable of 10000RPM (not bad for a 7.2L engine)

Early dyno run @ 25psi

1820Nm @ 7500RPM

2140hp @ 9000RPM

aiming for 2800hp with the boost set at 35psi

just the ticket for getting to work in my R32...

it says 10,000RPM not 100,000RPM. Its not a turbine....

the type racing this will be used for involves a lot of runs per meet, so it has been engineered to produce this power consistantly with needing a rebuild every run.

Basically nothing in the entire engine is off the shelf. Even the cam is considerably thicker than in the engine its based on. The write up on this suggests rather extreme levels of engineering.

7.2L, 4 turbos & 10,000RPM would sound unbelievable on the track

nah, the guy is fairly tight lipped about many of the exact details. there is just a repeated idea that 'it costs alot to run this sort of gear'. titanium valves, springs & retainers. billet ally/GRP rods, 55mm billet cam, magnesium/thin wall stainless turbos... its insane

i guess 'alot' would be quite an understatement

RB's are nice but i wanna turbo big block!

the 27L V12 Rolls Royce Merlin was in WW2 fighters such as the Spitfire, Mustang, etc. It was also used in tanks of the era.

Rod Hadfield of the Castlemaine Rod Shop fame has spent the best part of the last couple of decades engineering a Merlin into a '55 Chev body. Apparently it quite the animal. Its appeared on TV since its been finished but I still haven't seen it.

I was 15 last time I saw that car in the museum part of CRS & it was basically just a turret, chassis & engine.

That's Mike Moran's car + motor there, he's a leading edge drag racer in the states who always seems to be driving customer's cars for them. Then he decided to build a car for himself, and look what he got :D

Yep that car has been in a special zoom magazine drag edition last year!

It was pulling low 6 second 1/4 times in that same shell last year

      R34 25GT Engine Light 21

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.

      ECU sees many times the speed than speedo does (R34 swap)

      By GTSBoy · Posted

      It's needed for rolling idle up, and I think it is a decider on VCT also.

      I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it.
