whats the highest boost you can run on a stock turbo with race gas or without

 

1000 psi...you should search

 

That is going to depend on supporting mods! And we need to know what they are before we can answer your question. Unless that is you want a crappy answer.

 

35psi for either with the right mods.

 

6-7psi, anything higher may crack the block in half.

 

34-35 PSI must be with the 10.5 HS, on C16 and through an upgraded intercooler. As it would get pretty dicey on 109 octane race gas, and with the 9.8 HS, through the stock intercooler.

 

my mods are tbe, evc bc, headers, down pipe, 02 housing, 272 cams, w fuel pump, i have an up graded head gasket( thicker)not sure of ex size, fujita air intake with upper intercooler pipe, hks bov, stage 2 clutch, stock turbo, stock intercooler. thanks
