A long time ago people went with as low compression as possible for their FI motors. But, nowadays there is info to prove otherwise.
You can make the SAME WHEELHORSEPOWER with less boost if you run more compression. so at 8,5:1 compression youll need 35 psi to make 600whp. or at 10.1:1 you only need 25psi to make 600whp (assuming turbo setup is the same). which is more efficient? i would take the 10:1 motor.
Nitrous has a cooling effect. On a higher compression motor, you can run less of a Nitrous shot and make the same power. Or, cause of Nitrous cooling effects, you can run a 200shot on a 12:1 motor, AS LONG AS ITS TUNED RIGHT. timing and fuel are critical.
I knew a guy once that had this 11.7:1 motor, he sprayed a 125shot on his engine. it lasted and never blew up, he ran a 12.1
