What boost should i run with 91 oct?

i've seen guys with similar mods on this board on Dynos running like 24psi... i would thinking 22 psi... would that be safe?

 

You have to find the "effective" range of the turbo, and 21-22psi is spot on. Don't know about your fuel though 91 octane. Should be the same.

 

what do you mean the "effective" range... like a sweet spot idea kinda thing?

 

I'm going to guess 19-21psi. I know you can run 22psi on 93 octane with a tune. Every car reacts a little different so you really need to wait until your tune to see for sure.

 

well it is duned... KINDA.. it's mail-in reflashed

 

22-23 psi sounds good. the more octane the better.

 

u serious?!? u think on 91 i could hit 23? eh?

 

i wouldnt. I dont think al would recommend 23 psi on 91 either.

 

Yes I was talking the "sweet spot" I just wasn't sure about doing it on 91 octane. we have 93 out here.

 

I'm not Al or a tuner for that matter but I wouldn't run more than 21 (peak, like max on a 4th gear pull) on a 91 octane. It doesn't matter what other people boost, 1st of all you don't know the details of thier setups, 2nd you are the one that will be writing the check for a new engine after you pull the head and see melted pistons.
