On the site they have a dyno graph...

Can anyone spot the problem?

Here's a hint, its in red.

I hope the guy putting the site together is not the engineer designing the system. I know it may be a small mistake but still, its pretty simple math done wrong. They appear to be using a 15% drivetrain loss.

They dynoed 256.3 whp and tell you in red to multiply by 1.15 to get crank power - 256.3 x 1.15 = 294.745hp at the crank. Now that matches the claim of 295 but do the math backwards - 294.745 x .85 = 250.5xxxhp at the crank. The math is wrong. It should be 256.3/.85 = 301.5. They are losing out on advertising power. They could claim 300 horspower. I know I'm nitpicking at math thats based on a guess at best anyway but oh well.

Probably the more important part. The dyno shows a stock dyno of 179.6whp. Do that math and you get (gestimating the same 15% loss) 211.29xxxhp at the crank. Is the V6 underated from the factory at 190? Does anybody else have a dyno run of a stock V6?

My last question is for anybody with a V6 and PES supercharger (Julian and anybody else). Does the supercharged V6 feel "peaky" like the 1.8T with a chip. I.E. the low end is OK and then the engine just takes off. Or does it feel pretty smooth.
