just curious as to what kinda psi you guys have seen on a B18B engine. also for the people running over 10psi, what have they done to the engine to let it run that kinda pressure.

thanks
 
First off you do a lot or research.
Personally, I wouldn't run higher than .55 bar(8psi) just to stay on the safe side. Depending on the turbo.
To see higher boost you build your motor with lower compression pistons, rods that can take the abuse, etc. Also, you have the rest of the supporting mods to handle boost: fuel system, programmable ECU, etc.
There's more to it than just slapping a turbo on and going down the road blowing off at people.

psi doesnt mean much unless you know what turbo. 8psi on a super 60 is a lot different than 8psi on a gt35r

Funny story.....The tuner of revline motors is running a completely stock LS on 26psi making 315whp... but i wouldnt recomend that also he is on race gas.

He's a tuner and he's on race gas. Those are the kickers. I bet his AFRs are smooth as hell.
A buddy of mine had over 30 hours of tuning into his EM1 and he was making good power. I think that these are similar cases. Both tuners spent a lot of time to get their cars to that point. It wasnt just 10 pulls on the dyno to get the car set up to drive.
And you mean a stock LS bottom end correct?

no it was about 10 pulls :lol: he just did it the other night then took it to the track. yes some completely stock motor (form TB to drain plug) pulled out of an integra slapped in there a month or so ago. was making 200whp on like 8ish psi wit full exhaust on the ls befor this one then it started knocking so he put this on in there. he left it alone for a while driving his numerous other cars then i think he missed it. tunned it last saturday and took it to the track the next day. im pretty sure its just him pushing the limits i dont know how long he expects it to last/

went 12.1 at 121

ah cool, off topic but have you heard anything about go-autoworks.com they use garrett turbo's and stainless steel manifolds, kit looked perfect since i want a mini ram...but just wondering what you guys thought about them.

yeah but we all know that isnt really reliable. there have been cases of stock gsr's touching 500whp before. they dont last at that level and everyone knows it. to have a safe and reliable STOCK turbo car; keep it around or under 300whp
