My TA had no accessories on the engine dyno yet track numbers show more HP! PS, PB, full exhaust, transmission and rear end. So kind of opposite there. And it ran the same without any exhaust at all on it as with full X 3".

I understand what you are saying and why maybe the IA is less based on mph running an exhaust. But dynos like flow benches can be all over the place on the same engine, especially when you start using correction factors.


I still think knowing taking some off for accessories and some for a full exhaust would get us closer to comparing using mph. ET yes more traction/60ft bottom end issues(chasing that on the IA Camaro).
