what im not sure of is choosing the nozzle sizes. im looking to run around 20-psi and make 480-500whp. right now this is how i have it:

NO intercooler
running 50/50 (boost juice)
cooling mist 150psi pump
m3 (3.9 gallon/250cc) injecting at 2-3 psi (about 4-5 inches after turbo)
m8 (9 gallon/500cc)injecting at 7-8 psi (6 inches after the M3 nozzle)

this is how it is currently on my car. but before i get it tuned, it would be easy to change a nozzle. anyone here have experience with staged set ups? i dont want to inject to much to early. or just have it coming on so much that it makes it hard to tune. how much is to much when it comes to water?

 

y no intercooler? even though that's not your concern.

 

a few reasons. but the no intercooler thing always causes a debate. so im going to keep that to myself. if you wanna know why im personally not using an intercooler. you can PM me.

so a M3 and M8 sounds good. or should i step it up to a M5? anyone?
