Hello,

I'have a full stock B16a1 on my EE9 (EDM EF9), i'm ready to put a CTR intake cam and a B16a2/GSR exhaust cam. And i want to Know the best compretion ratio for this type of setup.
In the first time, i think to put the cams without increase the comp. ratio ... But i don't want to lose lot of power because i dont increase the comp ratio. Increase the comp ratio with this type of setup win a lot ?

Thanks,

 

Little up !

 

considering these motors run ~11:1 c/r stock that is what you should run as well.
