What are people running for boost levels on a 100% stock turbo/long block? Car was recently tuned (by someone very popular here) and was pushing over 30psi. Motor got destroyed not long after.

Post up below what your seeing on the gauge!

Evo X? thats way too much IMO, I was boosting about 26-28 on my X, 23 MAX on my 8 turbo. Seems much to me

Way too much on stock motor/turbo, with any fuel.

Currently tuned to 26 lbs on a stock turbo.

I saw your video on YouTube for this, I just recognized your name lol. That suck that happened, but I rarely here of anyone going past 27 psi on a stock engine. I believe stock the evo runs 20 psi, so going up 50% of that to 30psi is quite a jump! But to answer your question I am runnning 25 psi.

still way more pressure than a Subi can hold lol

If I hit over 30psi the AYC Service Required/AYC Disabled panel comes on.
My block is sleeved with cams and ARP hardware.
Is 30psi still the limit or is there a way to go a little over w/o tripping the AYC code?

I'd find a tuner that knows what they are doing, that is an EASY fix.

well we should ask Mitsubishi

My friend stock evo X was hitting 33 psi and it is still is alive

I'm hitting 35-36 on 5 gear but there is no sense to push car full throttle from 3.5 k rpm
but my engine is cosworth pistons and manley h beams about 515 lbs at peak and it is holding 29 psi at 6k rpms. It is really easy to addict I tried to drive at 31 and definietely I didn't like it

In my opinion it is useful and only can survive while using very smart not pushing the car from low rpms

my evo X on stock engine was set for a 30 psi no problems at all
