yes, a local Evo GA member does, so does another guy we know.

same setup, buschur stage 4 with alcohol kit, cams (272/272), fuel pump, stock injectors, stock turbo, stock manifold at 28psi or so daily driven.

little over 400whp.

run 25....just dont make it a habit of hitting boost through every gear. I was just tuned by Al for about 23 and my A/F was still on the rich side. Turning it up 2psi isnt going to kill me.

*sigh* I can't believe all these people talking about running so much boost. If you are on race gas daily or using an alky kit, then you can push 25psi peak, but it won't hold at 25 for very long. It will taper down to 21-22 anyway...

hay hay hay....read my first post, never did i say pump gas....i said i run 25psi daily on the stock turbo and short block.

he didn't even ask about daily when i answered....he asked if he could run it on the stock block and injectors.

FWIW, i would not run more than 22-23psi spikes falling to 18 without race gas. I would also not run more than 21-22psi without some sort of tuning device allowing some timing retard.

Thumbs down

warrtalon, do you have this setup? if not, why do you insist telling people you're right and others are not?

for me, i have 2 people with that setup I mentioned running 27 to 28 psi daily running here and in AL.

and yes, they hold up there pretty good.


it's not a peak thing without a mbc or with stock bov where the boost falls down.

<---- sucks i had to waste my 5000th post on warrtalon and his negative comments.

i hope you run good at the englishtown, because if you f-up, we'll all know you're a fraud.

you saying there are 2 people running 28 psi on pump gas?

warr is saying that people are implying to this new guy that they are running 25psi on 93 octane.

Its not about PSI. Many people think the more psi you boost the more power you make and this is wrong. Your goal should be less PSI more power. I would rather boost 21 psi and make 330WHP than boost 26 psi and make 345WHP or so. You are pushing your stock turbo to the limits on 26 psi and killing it for no reason.

Yeah, ploki, they run 28psi without alky or race gas, and it holds to redline on the stock turbo...sure!!! Gimme a break...how many times do I have to point out that Buschur and Curt Brown both have said that they disconnected the wastegate and let the turbo spike to 28, but that it would always fall to 19 or so by redline. I guess somehow your 2 buddies have super turbos that don't follow the laws of physics then?

You actually think that an MBC or BOV has anything to do with the stock turbo not being able to maintain 27-28psi to redline? Come on, man, you're smarter than that.

It doesn't matter what I run at E-town. I've already done it at 2 tracks here locally, and E-town is just as good if not better than both. Plenty of people have seen me hit great times, so that's a non-issue. So, how did it go when you went to the track the other day? You never posted anything, so I assume it didn't go so well...

eh, im not gonna need this turbo for 60k plus miles....

but you are absoloutly right about the rest of the post. i would rather make the extra 15whp though....but i agree, about making the most amount of power out of a given boost level. instead of just cranking the boost to make power. sounds kinda funny, but makes sense to me!

i'm saying there are 2 people running 28psi with alky and pump gas.

with dynoflash and proper tuning, why not run 25psi? it can be done. it's just not recommended.

and you're right, i would rather want to make more power with less boost then high boost and relative whp.


but really more boost, it may not give you as much whp as you would like, but it does feel a lot quicker and feels amazing.

and yes, it's funny, cause i ran 25 psi peak today taper to 23 psi, the whole day.

on shell 93 pump gas.

This is a good thread because I was always wanting to know what type of boost can I run(Daily) safely on SHI@TY 91 Octane plus mods: BR intake,3in DP,3in CB, stock cat, Walbro255,MBC, and a mail-in flash..

sure you can, its not reccommended because ITS NOT SAFE! you will lose power because the ecu will pull timing faster than you can say "ambesol"..
