my car dynoed at 280hp to wheels no sign of detonaton the knock goes wway down when its boosting its high at idle

Your question is not very clear. Could you rephrase it. If not I'll have to put Samuel L. up here.

i wanna know how much boost i can safely run on my motor on race gas with my mods

P'cola FD

Sam Here he is.

Without an upgraded intercooler I wouldn't go over 14psi if I were you . On my car I won't go over 12.5psi.

ha ha funny

quick94

mainly cause the intercooler is so shitty

quick94

what can the motor handle with a good one

P'cola FD

Without upgraded injectors I still wouldn't go over 14psi, but with better injectors you can easily push 18psi. Not on the stock turbos, though, they blow goats. Even at 14 they aren't going to last very long.

You don't necessarily need bigger injectors, but a fuel pressure regulator.

I know that Dragon ran an A/R .50 60-1 wheel with a .86 exhaust side for OVER 1 1/2 YEARS on a street ported motor and didn't blow the engine. The motor blew a water seal.

He had STOCK injectors at .8 kilos, but eventually turned it up to 1.0 kilos when he got the power FC.

without a good intercooler you run the risk of pre detonation running pump gas with boost higher than 12 psi

also, must consider if the pump can maintain the pressure if running much higher-than-stock fuel pressure with rising rate FPR.
