i try to search for this but i find nothing...

i buy on ebay 4x950cc injector but i recived only 3 !?!?!

so now, i need to use my car and i have only 450cc injector (and no more budjet)

dont worri about my built h22a4

i will use CROME for tuning/manegement (like uberdata)

i will try to make the most power with that 450cc injector

some one know how many psi i can reach?
i hope around 15
here the winter come very quikly, i will run my turbo lude on snow and i dont care about 500whp
i just want resonable power

but if you think this is bad idea, explain me why plz,

i never care about manegement befor, i alway used 7psi on stock engine so...

thx very much for your time

 

What turbo>?

 

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.

 

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

 

-40*C!?!?!?!?!?!?!?!? are you in antartica?? thats really ------- cold

 

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.

 

lol
i'M in foking canada/quebec
i hate this damn contry
i wait to finish the school to quit this inferno!!!!!

i run with a walbro fuel pump
so i'm not with the stock fuel pressur...

i hope to hit over 300whp...
i it 290whp on my stock engine 10/1 cr 7psi

 

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.

 

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?
