and a GP GT has a factory 3.29 final drive ratio in the Transmission, as compared to a GTP which has a factory gear of around 2.89.



thats why topswap cars are faster than factory supercharged ones.

*in a nutshell
I know this isnt much news to most of us on this forum or just mechanics in general, but this is what I like to here. I guess I should have known gtp's were low compression anyway. I already knew turbo/supercharger engines run a lot better with low compression...I just wasnt using my head this last night and this morning. Thanks guys.
