hi, i looked up for a thread like this with no success..
well, i have a question about the maximum safely boost

the boost gauge indicates 25 psi and the car is fast but i think that is too much for a stock GC8 with only exhaust and bov..

i need to know the recommended "maximum safely" boost that will not cause any damage to the engine, maybe 15 psi ?

-exhaust 3''
