i have a v6 3.8 camaro and i was just wondering what the compression is on those motors. i am hoping to try to put a grand national turbo kit or either a supercharger on it this summer. let me know youre opinions on which you think is better as well.

thanks

the 3.8's factory spec is to run at 9.4:1.
i think you would be better off putting one of the kits on rather than trying to modify a grand national setup to work. there is the powerdyne and procharger S/C kits and the turbo kit from Tiago @ forcefedfab. would save a lot of aggrivation.

 

thanks man ill look into those supercharger kits
