just 12PSI, stock compression ratio (11:1), I am going to put a GT3076 Turbo with a 3mm headgasket to lower the compression and shoot for 20PSI in the fall and shoot for 550RWHP, thats Viper killer territory

The Meth injection does wonders to lower EGT's, CHT's and is equal to like 116 octane, I know some older Turbo-prop airplane used to use water/meth injection, its amazing
