Volcano, you honestly expect an answer out of a 4yr old thread from a guy that doesn't even frequent the forums anymore?

Congrats guys, you've successfully raised the dead.

 

^^^^dude, really .....a post from Feb 2007? Tuning has changed so much from then. Check out the dyno sectionor something for more updated info. Ha

 

I was running 30psi on my stock turbo with 93 and meth.

 

e85 running on 26lbs no issues stock turbo/internals

 

33-34psi with 93 and methanol as well.

 

I recently downloaded the Cobb AP Stage 1 ACN91 V400 which peaks at 26psi. What do you guys think about that 0_o

 

Holy thread revival. 26psi on the stock turbo isn't too much, as long as the tune going along with it suits it's needs.

 

26 lbs no prob

 

 

Just bumping this post from the dead, but I ran a 22.9 PSI on stock 8 turbo. Mods are 3" downpipe with o2 dump to the ground, ETS 2.5 Lower IC pipe, AMS 3.5" FMIC, stock MAF, stock upper IC. Did I overboost or am I good? It was about 55 degrees out that night.

 

Your mods are overkill for the stock turbo, so no worries there. The FMIC may be slowing the turbos response, but that won't hurt anything.
I ran a hell of a lot more than 23psi while on e85. As long as you aren't seeing knock or lean AFRs, you are fine, assuming you are tuned for everything.
