Highest PSI on stock Evo 8 turbo
So me and my friend were arguing how much psi a stock evo 8 turbo kit can hold. He says it will blow up past 27psi. So instead of asking the typical rating I wanted to know cold hard fact's. So what's the most psi you ran your stock evo 8 turbo kit???

It is true, just because people make 400 hp on a stock turbo doesn't mean it's still not very efficient up top. It just can't flow that much volume. If u combine e85 and enough supporting mods it's not hard to hit 400 hp on stock turbo. E85 helps cool combustion temps some and an FMIC will probably help keep it more consistant as well. IMO though u can't beat an e85 evo viii with stock turbo making 400/400 dynojet numbers, very smooth and fun to drive and dead reliable. Loose that pull on top, but still fun.

Turbos run what they run. But 27psi isn't the end of the rd. Mine spiked 33psi on cold nights, has 88k on it and wasn't tuned or modded until 80k, and the snail lives epicly. The oil you use, ontop of your tune quality, ontop of a well mannered driver promote the longest turbo/anything life expectancy.

I have had 4 evos, all of them running fast and quick, some of them on E-85 and some of them on methanol. I have a post back in 2005 or 2006 showing my car spiking to 31psi. Most of my cars running E-85 or methanol had no problems spiking to 31psi but in reality anywhere above 27ish PSI you are not making much power.
I made a post back in 2005 when I had a Evo 8 MR making 364lb-tq(bench mark back then on 91oct and methanol) and I made more power on 26psi than I did on 28psi.
Do a search in my name, I documented everything and I spent hundreds/thousands of dollars going to the dyno and having various set-ups and tunes. Tell your friend that he knows $ $ hit.
