There isn't really a safe level, it depends on the health of your motor.

I think you should be asking how much horsepower can a GSR handle before my stock internals snap.

Boost pressure is irrelevant, hp is what is relevant. You will be safe under 400whp depending on the condition of your engine.

I have the same question.
But i have heart that not HP will kill an engine, but torque.
What is a safe number of torque with a gsr?? (around 250?)

theres people making over 400 for a long time now. but in the 300 range is pretty safe.

Re: what is safe boost for a stock gsr?

Wow...i'm surprised this thread made it as long as it did.

As with all turbo setups, PSI is irrelevant. Each turbo makes a different amount of power at a different Pressure Ratio. On your stock GSR on pump gas, you're limited to around 300-325whp safely. With higher octane fuels like E85 or race gas, you can make more; however, with added power comes added stress on internal parts.
