Actually.. on second thought..He may be right if you wanna supply fuel to your setup correctly.. I think the 440cc will work fine for most, but I am a optimum type of guy so i decided to look into his reasoning..
Check out this calculator. I think this may just put the final nail in the coffin to the debate lol..
injector size calculator--
According to this calculator, the 440cc injectors would be good up to 215HP at 80% duty cycle @ a BSFC of 0.625 (BSFC is .625 for turbo)
So for my goal of around ~350 Hp would be 717.8 cc sized injectors or bigger.(running at 80% duty and 0.625 BSFC)
Damn.. looks like im calling luis for the $99 fuel rail and just go from there. Just remembered the 3rz stock fuel rail is only good for 550cc?? correct me if im wrong... lol damn it. MORE MONEY MORE PROBLEMS!!
