What's the max boost an S5 T2 can handle?
 

Just wondering what the max boost an S5 T2 can safely handle? I got a jspec ECU when I did my conversion, which contains some kind of aftermarket chip in it. Anyhow, I don't get any fuel cut and during my last run, I hit 12 psi fairly easily at about 6900-7000 rpms.

I thought it could be the boost gauge but its an Apexi EL, so I think those are fairly accurate..
I'm not really wanting to blow my relatively new engine, so when should I be dropping off? Around 11-12 psi?

i believe that the stock turbo wont boost much (if any) more than 12lbs.

as long as you're not running lean and 12psi is your absolute max boost with no spikes will be ok for a while. 10psi is much safer though.

I was running around 12psi on my S5 with the stock turbo and it took about 1-2 months til the oil seals crapped out...then again it was an old turbo with a bit over 100k miles on it. :p:
Personally, now I would stick with around 10psi but in the end it's your call if you want to push it higher or not.
