safe boost pressure

Post by neilchan1981 »

Hi does anyone know what a safe boost pressure would be to run on a stock engine and turbo. I have heard that rings are good to 1.2bar?

All depends on....

Condition/health of your engine
Year - in your other posts you were talking of a fcd so you must have a rev 1-2
And mods you have. Do you have an upgraded intercooler? metel head gasket?

No more than stock and even then the ECU is controlling on the knock sensor a lot of the time
