what injectors to use with 350-450whp?
right now i have a set of rc 550 cc's. I want to keep the injectors at about a 80% duty cycle. The motor is a b16 on a 57 trim turbo with forged internals. i want to make from 350 to 450 whp. I know i have to change the 550's so what size would be just right for this horsepower number?
thanx

curious on why? why not just get 1000's/96lbers and not worry about it
you know how boost is addictive

how your gonna run 6psi daily and make 450whp.. swap out the WG springs whenever? I doubt you will make 450 on 12psi.
Anyways.. 750's should do it, 780's is what im running.

i forgot to add i have a turbo xs boost controller. Im not trying to make 450whp on 6 psi. 6 psi i should make like 220whp. on about 20 psi i should be pretty close to the 400whp range if not past it. High boost is only for track days. What power should i see with the 550cc's at 80% duty cycle? like 300whp?

ya thats what i thought that 750cc's would be just about right for my setup and horsepower goals. Now the question is what horsepower will the 550cc's make at 80% duty cycle? Im guessing around 300whp.

I have maxed 440's out at 100% duty cycle at 317whp on a dyno jet. The last set of 750cc's I maxed at 100% was at 470whp. I don't recall working with too many 550cc set-ups... but I think at 80% duty cycle will net you around 340-360whp with stock fuel pressure.
Anyways, go with 750's as everyone else has already said.

because i want an 80% duty cycle to ensure that i have a really good spray patern. And if i do build another block later on it will be years down the road so theres no point in having the 1000's.

Re: (92redhatch)
not trying to jack your thread and I can delete this if you like, but does anybody want to chime in on 1000's? would there be any problem running 1000's at 300-400whp? Would it really be beneficial to use 750's?

the spray pattern. At 80% the injector has a great spray patern. at 100% the spray pattern sux. and anything under 75% the spray pattern isnt so good either.
