WEll i got the BC working right and now its time to make a decision. What do you guys think about the PSI i should run??SIG has the mods.

 

[SE-Rawkus]

What is your compression and what kind of gas do you get in CT?

Manny

 

[Nismo91ser]

not sure the comp.but it was bought from SOKO. And i run MOBIL 93 octane and thats it!!

 

[spdracerUT]

i wouldn't go past 12psi.... you might get away with 15 but listen for detonation. I have a feeling 18 is too high.

 

[Low612]

I wouldnt run more than 10psi on a stock comp DE motor. If its a det 12-15 max with pump gas is what i run daily.

 

[Creagach]

i didn't see anything about an intercooler.

You can get away with 12 psi (max) on a DE motor. 12+ psi..better have a DET.

[Nismo91ser]

WOW!!! I ran 15psi on my old T3 super 60 all last year!!

 

[afstegg]

come on 10 to 12 on a stock 9.5 motor.maybe if it was a honda the motor can handle a lot more then that. 15 psi is a walk in the park. just keep your eye on the egt's and listen for detonation

You must have a DET.
15 psi might be a cakewalk for the 9.5:1 motor, but that is really pushing the limits. I personally don't want to ever hear the sound of the so-called "pinging."
It is better to be safe than sorry. On the other hand..if I get my hands on some C16 gas...15 psi all day long.

15 and see how it reacts. Try 18 on some colder days to start out. If its ok then Try 20 Degrees advance timing. Right Steve?

Or some race gas

 

[Nismo91ser]

hehe AFSTEGG is my brother and he has a JDM SR20 too. I guess the Miller brothers are crazy!!! We both ran 15psi last year, on 93 octane and no pinging!

That seems a little ultra conservative there man. I boosted 15psi all day long on 93 octane with my BB motor, and i could run 18-19psi on the dyno if i wanted. Never heard any detonation with the stock ignition and i used a wideband O2 when I dynoed. I think he is safe running 12psi even with the 9.5:1 cr as long as he uses premium.

Yup, I have a US spec motor (9.5CR) and I run 12psi all the time with 93oct.
