I searched and came up with all sorts of answers.

I used a couple of injector size calculators and came up with about 720cc. This was calculated at 400hp which i would like to get close to.

Reading some forums i see some people claim 550cc will acheive 400hp.

I can get my hands on both 550cc and 850cc side feed high impedance injectors dirt cheap.

So my question, to those with high hp sr's, is will the 550cc supply enough fuel to make 400hp.? Are the 850cc injectors too big to use adequately?

fuel system already has 255lph pump and an adjustable fpr. I will be using a s-afc to control the injectors.

ThxPhilip

yeah people say you can push them to 400hp but thats with some good tuning and a good fuel set up but its not recommended. your best bet is your going to be around the 400hp range i would go with the 740's so that why you have a nice comfort range where you can have fun with your turbo set up

If you have a good tuner you can get 1000cc injectors and run 200whp, its all in the tuning. Injectors just limit the ceiling as far as how much gas you can put into the engine.
