    Per the label on the motor it is 154.5kw (207.18HP) Stock. No way in HELL is it 285HP Stock.

    That depends on about 100+ variables. A MoTec Plus what. It would be kind of silly to run a stock SHO with MoTec. A stock SHO with MoTec ECU would still not be 280+HP.

    Okay, this may be from the dumb question department but.... how do you actually measure horsepower?

    We guestimate based on the results that companies like RIVA and R&D and Motec are able to achieve on engine dynos with different combinations of parts.

    I thought I read that a MoTeC will add around 30 hp and another 30 hp can be had with the MoTeC and stage one mods.

    Actually, horsepower is not measured. It is calculated using 2 specific variables that must be recorded at the same time: Torque and RPM. The mathematical formula to calculate horsepower is:

    Horsepower = (Torque X RPM) / 5252

    According to Pete's dyno tests, the Motec alone will add 38hp to a stock engine. The jpeg is different SC wheels + Motec & the PDF shows HP increases with some basic mods. I believe the +27hp increase with the monster wheel was done with the old C1-7. I'm also not sure if that was on a boost limited engine since the PS wasn't out yet back then.

    I agree with you. I can't help but think what the second dyno run would be now with the modern parts available like intercooler, injectors, extra cooling especially to the IC, etc...
