i'm running 7psi on a stock motor right now with aem computer, what i would like to know is if i was to run 10psi on a stock motor without a head gasket how reliable is that going to be, for everday driving? and have anyone try running this setup?

 

I have run mine at 9psi with no head gasket for almost 8k miles. no signs of problems what so ever. Just get a good tuner.

 

 

From my research. 10psi would be max on stock internals. Get a good tune and you'll be fine.

 

I've hit 15-16psi a few times, and it didn't kill the motor, but that's only because I had the GM solenoid hooked up wrong After I got it right I was running 12psi for about a month with no issues. The car was then backed down to 8psi while I'm overseas and will be getting the 2mm gasket treatment when I get back. Planning on 16psi.

Now that being said, be careful. My car is not a daily driver and to be honest I didn't care if I popped the motor. It would have just forced me to rebuild it, something that's going to happen sooner or later. For a daily driver I wouldn't push it. Nothing else get a EBC and do a high-low setup.

 

I would def recomend the EBC specificly the greddy. Easiest one to work and for an xtra few bux you get the steering wheel button to swich between high and low boost settings. If you have a AEM its a must

 

If you have a AEM unit then buy the GM solenoid and a switch and you can have the same thing but save yourself around $200. The greddy is a nice unit, but it's not worth it when the EMS can do exactly the same thing it can.

 

I def feel you on that . Im just not crazy about letin the EMS handle my boost settings. I want the ability to go between high boost and low boost without hitting a toggle switch just pressing a button and it looks cleaners too IMO

 

LOL so you have no problems with it controling your injectors or timing, but not your boost? I mean to each there own for sure, either way gets the job done...it's all about presonal preferance. BTW, you could buy a push button for the EMS just make sure it's not a momentary switch, otherwise you'd have to hold it down. And that would be no good

 

It depends on the turbo kit, injectors, tuner, fuel run, and a variety of other parameters. There is no "yes, you can run 18 psi on every turbo kit on a stock motor" sort of answer. There's also no way to say "10 psi on any turbo setup is too much for the stock motor".
