my car has 70k miles on it now, i was wondering if it would still be safe to raise the boost?

 

damn 70k!!!!what are you boosting now?

 

yes. I have 61,000 miles and have been pushing 17 psi for 3 years now.

 

How much can the stock motors handle?! Moreso, how much can the stock turbos push?

 

those are the wrong questions to ask because its not "how much can the motor handle" ... these motors can handle more boost than you'll ever see. You'll have to worry about power output more than boost capabilities, on these motors. The drivetrain is good until around 450 - 500 HP.

As far as stock turbo, it can push up to 19-20psi safely and still be "efficient". Once you go above that, the turbo becomes very inefficient and useless lol

 

Inefficient and useless... as in broken? Haha

 

lol

no, the turbo can spool fast with no problem but once these turbo's start to spool faster than 20psi (give or take a few lbs) they become inefficient because you'll just push hot air into the motor.

 

NOT!!!!!!!

 

but you raised boost before u got to 61k, but i was wondering now since im at 70k if it would be safe to raise the boost since it has a lot of wear and tear now. im getting stg 2 w/toys and an agp wastegate.

 

as long as your engine is running fine, there's no reason why you cant turn the boost up at 70K. There are people with over 80K and still running fine.

As long as you dont see any problems with the drivetrain, boost away! If you're nervous, then get the engine checked out. Have you changed your belt? Changed tranny fluid?
