Hello SFLDrifters,

I am confused and i'm hoping you fellas can help me out.

I am raising the boost on my sr to 12psi. Stock everything except for a fmic and hks actuator. T25. My question is simple. Is it indeed unhealthy for the engine to raise the boost? I mean, your forcing more air into the engine and your fuel still thinks your running 7 psi so wouldn't that mean your leaning out? Don't I have to increase the fuel pressure as I increase the boost?

Thanks in advance lads,

Leo B.
 
The injectors can handle more then 7 psi, on my old black top I ran 15 psi all day stock injectors and never had a problem and I ran it like that for like 6 months untill I totaled my car, 12 psi u should be fine, I ran 12 psi in my car and my AF readings where like 12.5-12.9

I've read somewhere else before that theirs a guide line for increasing the fuel pressure. For every psi of boost you increase x amount of pressure for fuel. What is the X?

i think for every pound of boost it increase one pound of fuel pressure... correct me if im wrong :confused:
 
leo, when you raise the boost, your ecu can see that from sensors (i.e. o2) and can accommodate by adding fuel... to an extent.

12 pounds would be recomemded to have a fpr right? he could run 10 easily without an fpr . do you have a boost controller ? and im hoping you have a boost gauge right?
 
ive run 21-22lbs on my t25 sr20det with 12.5 afr across the RPM range.. i wouldnt recommend it thought. Leo, go up to 12 psi and call it a day, fuck the rest

thats the most retarded/useless thing ive ever read on this forum - Im sure u prolly made like 450rwhp too right?

actually, it made 303 hp on my in house dyno here at work. how is this useless, i was simply stating that it has been done, and by me saying "i would not recommend this" was a sarcastic way of saying "this is retarded, dont do this"
