what size injestors to get for 600 hp

[nkosi]

hey can someone help me with picking my injectors for my build this summer i want to keep driving the car while i wait to start build so what size injectors and what fuel pump do i need ...i saw they have a dual walbro setup at maperformance is that too much or a single walbro with upgraded feed and return lines to -8 an will be needed ... thanks guys

600 to the wheels or crank?
I'll guess; to the wheels (650 crank), 65psi fuel pressure (43+22boost), BSFC .65

thanks for the reply dude and the link to the RC site to do calculations base on hp ...it says i need 1200cc injectors at 80% duty cycle...now i just need to know what fuel pump and lines i need to feed the fuel rail ...and yes im looking to get 600hp to the wheels ..

Keep in mind that race fuel, e85, and pump gas also change this requirement. Meth injection also effects this.

i think for over 600 you'll need over 1000cc injectors and a duel walboro 255 setup

600 whp on a awd is 750 crank with a 20% drivetrain loss, which is the standard loss we use with our cars. In order to keep duty cycle under 80% you would need 1250's. Also without knowing what turbo he's running you can't even guess how much boost you need or fuel pressure to make 600whp. Not many 2.0 cars can make that much power at only 22psi. I know I'm making around 545whp running real rich(needs more tuning) seeing 84% duty cycle on 1150's.

hey man im planning on running with the FP DSM82 HTA BB turbo and i calculated i would need 1250cc injectors ...i found them at advanced fuel injection ...Lucas 1200cc units on specail for i think $270...
