What is the highest psi that an evo 9 turbo can handle? and what is the guarenteed blow psi that it will blow up on? Can it handle 30psi? with mods? I was just wondering, thanks.

 

Search. Most people can run 30 psi on stock 8 or 9 turbo on c16 or e85. On pump I wouldn't go mucH past 25

 

Yeah i was just wondering since i am going on e85 soon, now am running 24psi on 9 turbo.

 

30 psi is attainable easily without boost leaks

 

I spike at 30psi on a 93 octane tune but it tapers off quickly towards redline

 

Talk to TSCOMPUSA about that. It seems that his tunes can support 30psi+ safely.

 

im running 27 daily,spike to 30.93octane,for 8months now..

 

I run 26psi daily.... Only falls to 23-24 around 6k.

 

I'm getting mine tuned to 25 next weeks stock turbo.. Curious as what ppl are puttin down with 25+ with cams and such.. Didn't mean to thread jack

 

Running 30psi all day long on E85. 25psi on pump and seems to hold it ok.

Kanovic, with appropriate bolt ons, you should be around 330whp on pump. Shy of 400 on E85.
There is also a thread about this. State your parts, and people with similar mods can relate.

 

Running 30psi on my evo 9 turbo.

 

mine is, 26 psi max and mine tapers to 22PSi, And i have a boost leak on 93 Oct

 

I ran 30 psi on mine on 93 oct with no issues whatsoever,34 on racegas for track duty as it was the max i could get out of it with the wastegate closed shut and no boost source going to it,,it's mostly in the tune and supporting mods that will allow you to run that kind of boost safely.

 

330whp at 25 psi, im at 22psi with bolt ons and it dynoed 352whp w/91oct

 

40-41 for peak power
