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

      I know people cry at the price of the Getrag 12-14k for a conversion now, but it really is a nice mid point. Not going to get change from 10k on a gearset installed.  $30k++ for sequential.   I know you run the risk of a damaged used one and parts are hard to get but as a street car gearbox its really hard to beat. If you enjoy a more traditional manual, its the choice no question.
