What turbo>?

Re: how much power/psi with 450cc injector???
Max hp you'll want on 450cc injectors is about 325~350 with reasonable fuel pressure. Figure up what pressure ratio your turbo supports that much power at and don't go above there.

Re: how much power/psi with 450cc injector???
for now, my turbo is:
Size: T3/T04E Compressor A/R: 0.70 Compressor trim: 54 360° thrustplate, dynamic seal, integrated backplate Turbine A/R: 0.6 Turbine trim: stage II like i said, this is my winter beater setup, i will upgrade for the next spring i spend my last penny on the ebay auction for the 950cc injector and now, i wait for refound but i need my car NOW so i go for low power (anyway 950cc are supose to make rough idle, for winter with -40c...) my CR is 9.5/1 |

Re: how much power/psi with 450cc injector???
hmmm... kind of sounds like we're in the same boat.... kinda. im also running 450s and at 13-15 pounds (t3/t4 50trim) i can't get my A/F ratio below 12.5:1 so i just keep it at 11psi. :-\ Ive also got the fuel pressure at stock.
i keep reading that dsm450s are good for 300hp and i'm kind of confused because i don't think i'm hitting the 300whp mark... if i was then i guess that would be cool too. i'm running on super low compression d16. |

Re: how much power/psi with 450cc injector???
ive messed with setups running as much as 30psi from a big 16g, but we were also running methanol, so we didnt use as much fuel.

Re: how much power/psi with 450cc injector???
this is how i look at it, stock h22 injectors are 370cc.. so you only have 80cc's more with the 450's.. when ever i tune i start off at the 370 mark and scale from there, i dont see you making more then about 260-270 with 450's on such a big motor.

ive always thought methanol used like 1 and a half times as much fuel as gas? could be wrong but i believe thats what i was told? |
