Hmm... I have the Hahn 20G going into my car right now... Stage 1 injectors, boomba fuel rail, and a return line. I'm using a fuel pressure regulator and fuel pump from Hahn. Not sure what kind of pressure the fuel pump they sell puts out. The only fuel pump I can find on their website just says it's good for up to 500 hp.
I was trying to do all the calculations, just going off the Stage 1 injector flow rate, I was thinking I'd be maxed out at around 15 psi which should put me in the 300 to 340 whp range, with what I have now. Does that sound about right?
Can you really max out the 20G on Stage 2 injectors? I want to hit around 400 whp eventually, I know I can't do it with the Stage 1 injectors I have now. I was thinking about going with 750cc injectors to get there, but if I can reach that with Stage 2 injectors, I could pick up a used set of those and save some money. If I'm not mistaken, I'll need to push around 25 to 26 psi to get up around 400 whp.
BTW, this isn't for an SRT-4, it's a 2.4L Sebring Sedan.
