I was there and in fact, Jeff puts 602rwhp (so at the wheels) and 647hp at the flywheel.

Both number were given by the dyno on the same run.

There's at least a 15% drivetrain loss so 602rwhp would be at least 692 bhp.

The transmission loss has been measured by the dyno.

I've never seen a M3 with 15% loss on a dyno in Europe.

The average M3 stock dyno number here is 280rwhp on a dynojet dyno. 280 x 1.19(19%) is 333bhp (north American hp for the M3). I use 15% to be Conservative when dynoing. either way 600+rwhp is a good # on any dyno.

You're right only if a stock M3 really has 333bhp
In France at least, most of them are between 325 and 335bhp (instead of the 343bhp advertised)

I know it's a sensible subject and I don't want to start a war US vs Rest of the World regarding the numbers

The only thing I can tell is that our dyno gives us :
-602whp ( measured )
-45hp loss ( measured - I don't know how to explain the process in english, but I can in french ^^ )

- 647bhp ( calculated : whp + loss )

In the end, numbers are just numbers, the most important thing is that we are very happy with the results and the car is so fast, it's crazy.

Of course ... The risk is high.

It's the fuel system stage 1 from HPF Turbo kit.

750cc injectors, 2nd fuel pump (not in the tank) and Edelbrock filter.

Re 6776, maybe Chris able to answer ?

So i think 6766 is the best, more torque at 3500 and 820HP max it seems
