Joey, you can run more than 8 psi on stock hg - many people have gotten away with nearly 10psi with turbo and a good tune. I'd get it looked at every time the weather changes drastically though (summer/winter) to be safe.

hm I wonder if after a Test Pipe the Boost would drop a little. Just wondering if buying a Boost controller is worth it, if 8psi is the safest/highest PSI I can go on a stock HG, I was thinking maybe 9 with a good tune, I would imagine 7PSI to 9PSI is a fairly good amount ot HP?
On a greddy kit, 10psi is about 300hp.

10 psi is the most on the stock headgasket. Whats the reason they're blowing? Is it the psi/power or it just the install difference? I've seen other people doing 18+ psi and fine then 14psi and blowing them. Im getting ready to do my commetic 3mm headgasket. I know there is a some little stuff that has to be done correctly to get the proper seal/ install.

There are a lot of HG failures.
It doesnt make sense to me to use the thicker HG, All that work, and extra money, lower performance, and still a risk of the thicker HG failing.
Spend the extra money on a good tuner.

Wouldnt you make more power with a 3mm headgasket than a stock one bc you can go higher with how much boost your run?
Great tuner or not, I wouldn't trust 18+psi on stock compression, no other turbo car runs such high compressions.

He's implying less horsepower vs a stock compression car.

I'd rather have a blown head gasket as opposed to engine failure.

Shit's so confusing, people say dont go over 8psi or 10psi on stock compression then others saying there running 12+. I plan on running 10psi stock head gasket on the full race stage 2gt and hope to make 375-400whp reliably. We'll See

a testpipe will raise your boost due to the reduction in backpressure.
On a greddy kit, 10psi is about 300hp.

you'd be suprised then, the turbo is very small. Seems a lot of people were tuned for 9ish psi due to creep and the power was around 295-300.
Its unfortunatly, but thats the kind of power this kit makes; people have to understand that.
