I'm running a TNT f2 kit on my 422 now. 500rwhp or so on motor alone. It's jetted at 100hp, I haven't had a complete dyno since the install, so I'm not sure what actuall rwhp will be.
So assume I'm crazy, and want to jet the kit to the kit max pill size of 250.
What would I need to upgrade? I know fuel pump (give me some recomendations and reasons), I figure injectors (currently having injectors that are 36 lb/hr at 43 psi which means on my 60 psi fuel system they will be rated at around 41 - 41 lbs/hr.)
What else? custom fuel rails?
