How much Boost can my bottom end take with my setup?

[T-REX]

With the set up in my sig how much boost can I run safely without blowing up my bottom end. It is stock and has like 120K on it. thanks

it's not how much boost, it's how efficient the boost is. non-intercooled it could lean out and go at 12PSI and intercooled it could go allt eh way up to 30PSI if you keep inatke temps down and enough gas in there. except i've never tried so my opinion is just speculation.

I have an entirely stock 88 T2 motor, and Ihave run it between the 'O's in the word BOOST at the bottom of my Autometer 20 psi boost gauge(So I would guess I was at 25 or 26 psi-It was hauling a$$ and still torque steering all over the road at 100 MPH,LOL). So I would say as long as you have EGT(keep it under 1550 degrees) and A/F gauges(all lights lit at WOT), keep it rich enough and no pinging(good gas, good cal, not too much initial timing), you can probably go 25 psi on unleaded race gas/18-20 on 94 octane pump gas.

NOTE: I will not be held responsible if you break a piston or two,LOL
