n/a injectors
I'm trying to put together a setup for my future car. What would be a good size for injectors with ITB/velocity stacks? I'm shooting for 250hp. Any input would be great. Thanks Alex.

Yahoo search for "injector size" turns up this:

Looks like you're gonna want to have 400-500cc injectors.
Before you ask: Some searching on here will reveal that the stock injectors are about 360 and stock fuel pressure is ~43psi.

stock injector will handle up to 450hp.... but with like 80% duty cycle. you should be ok with stock injectors for the 250hp.
here's a simple calculation i learned from an expert but he didn't tell me what the "5" is for.
injector (cc) x 5 / # of injector = ~hp
so let's say 360cc X 5 / 4 = 450hp
i have ITBs and running a 427cc (44lbs) injectors... 20-30% duty cycle
