If Chevy is accurate with the 415hp number and not under-rating it at the crank then 360hp is about a 13.25% loss to the wheels... not bad... I'd really like to get a manual down the road though....I'm holding out for a manual.... even though it may never happen for the US version of the Commodore, and I may never be able to afford one anyway lol....one can dream lol.
Sounds good. Yeah I knew the Camaro was rated at 426hp... and if you subtract 18% off of that you get 349.32... the dyno run was 359.79... so either the drivetrain is a smidge more efficient or the engine has a tad more power...or the dynojet is a bit enthusiastic. Either way I like the car... I know it can and will put up good numbers with even moderate mods and a tune...let alone forced induction :biggrin:I don't think GM certified this engine for the SS, it was when released for use in the Camaro. With that application it was rated at 426hp/420tq, and it picked up a bit when the EPSA was released. It is very possible the 415hp is just a conservative guess. The A6 (6l80) in the Camaro had a loss on average of 18%.
