i have 8 psi (blower)on my stock motor now and im planning on going turbo at 10 psi.
am i pushing it?how long will it last with a good tune?

thanks.

 

I'm at 7psi turbo right now. Would have been 10psi but my 2mm head gasket didn't arrive in time for tuning, and I didn't want to push it that far on stock compression. Next time a tuner makes a trip out to Hawaii I'll throw the headgasket on and up the boost.

 

It all depends really
Stock motor with stock headgasket I think 9 PSI has been proven on here.

2mm or 3mm headgasket you can up the boost to 10-15 psi.

 

what hp are you running at 7psi,

 

its all in the tune... a bad tune on 5psi can F&*K up your motor as well

 

wel i wanna go faster,,,,,with no headaches like turbo,cracks,leaks,ect...
ive had my blower on for 2 years and never a prob,but i want more hp....should i change the pulley for a 10 pounder and buy/wait for the new aem piggy back to come in for mananagment because i assume my votec black box wont be a good pre tune for 10.and should i go front mount intercooler other then my vortec small one.

thanks for the help peeps

 

With a good tune, good gas and good luck you might get away with a full bar (14.5 psi) if you don't beat on it. Some in the short term have pulled 600 hp or more out of this little engines stock bottom end. Long term remains to be seen and still depends on a good tune, good gas and good luck.

 

He wants to know what the maximum amount of boost our motors can handle, assuming the best possible tune.

 

With a 3mm head gasket and a good tune, I'm running 21psi. No problems so far (knock on wood)

 

No need to knock on wood JC, Rick has that car dialed in

I'm running 17psi on a 2mm right now with no problems. Was running 12psi on a stock motor before I added the gasket. It's all in the tune.
