Default 947 bhp 3.1l 16v turbo
Hey guys.
Some of you might have seen this on social media.

We put my race car with my latest 3.1l 16c turbo engine on the dyno the other day.
Tuned it from base boost at 1.0 bar up to 1.8 bar.

Max power 947 crank hp with 966 nm. 855 rwhp.

Very nice.

Could you share some details? Compression ratio? Fuel? Timing?

Thanks!

I don't want to give out all details but the overall spec is:

3100 cc / 16v
solid lifters, billet cams
4-1 headers
BW EFR 9280 turbo
Turbosmart 50 mm wg
Revline short runner intake, TB & fuel rail
2200 cc injectors
Dry sump
Revline billet one piece flywheel with Sachs RCS 5.5" 3 disc clutch
Haltech Elite 2500 ECU
Motec C185 logging & dash
Motec PDM electric system
E85 race fuel from Goat Fuels (Swedish supplier)

It's a very efficient engine that makes around 726 bhp @ 1.05 bar.

Congratulations Duke! A lot of research design and testing (and talent) pays off.

Wow.

Congrads

That is freakin awesome.

What is the tooth count...I am guessing 60-2 on your flywheel?

Can you say if the block is running liners or Alusil, and the make of the pistons?

Wow! Congrats. I would have expected more RPMs. Must be a beast! That's better than a lot of famous Porsche racing motors. Do you have a race event/series planned for it?
