Generally, 6MT models have a 18-20% drivetrain loss (depending on engine). In the case of HansMolen, 298*.8(20%)= 238.4, so thats pretty good.
With the 5AT models (which 03-current are pretty much the same power wise), you're looking at a 23-25% drivetrain loss. I wish I dyno'd mine stock because I only have a theory on where I started: based on the mods I put in, my theory is I started somewhere in the neighborhood of 214 RWHP (I am now up to 238).
Best thing to do is get a dyno run bone stock, much better then wondering where you came from (like me).

Quick lesson on Horsepower/Torque
Check my thread "Dyno Stock 05 6MT Before/After MREV+"
HansMoleman's G35 is making 238 HP because they only reved it to 6250. Remember, horsepower is only a calculation based on torque and RPM's. So, if we assume the Dyno operator had run the car to 7200 RPM and if the car was making aprox 190 lbs of torque (perfectly reasonable for a 2005 6MT) the same car would make 260 HP.
HP = Torque x RPM/ 5252
I know what you are thinking "where did the 5252 come from?" It has something to do with a horse and a weight. Google it.
That's why 200.5 lbs of torque at 6250 RPM = 238.6 HP
I calculated this by reversing the formula. You can determine torque when you have horsepower and RPM's. or...
Torque = HP x 5252/ RPM

Mustang dyno always reads less therefore his numbers seem low but when compared to the dynojet its ~250s.

I AM NOT BLOWING SMOKE HERE, THIS IS THE TRUTH.
If his G had been run to 7200 RPM it would have made +/- 260 horsepower.
