What hp range DSM 450cc injectors can handle under fuel pressure of 50psi ? and what fuel pump should I install ?

It'll tell me more about what could be my goal and what I need.

Thank you

ive been reading on here as of late that a 225 is overkill and that a 190hf fuel pump will work for anything a d can put out. i think the 450cc max out around 280/300? could be completely wrong someone correct me

I've heard the same thing about the 190 vs. the 255. I think everyone just uses the bigger one for an extra margin of safety. As far as the 450s go, there's a guy on here that ran 322WHP with them, but that's really pushing it.

@ 43.5psi Rail Pressure, Xwhp at 80% Duty cycle
450cc - 259whp

@ 60.0psi Rail Pressure, Xwhp at 80% Duty cycle
450cc - 304whp
what the calculation for this? or did you use a calculator? I could of sworn someone posted a injector calculator or was that on HMT. 259bhp on would be fine with me for 450's. stock pressure on 450's is 43 huh?? I'm running them at 36 right now......
