more boost

[88e30]

I'm still trying to work all the bugs out of my turbo to make it run properly, but I want to know what would I have to do to run more boost and not destroy my engine. I am running 7psi now I want more. My car has about 170 on the clock.

as always, a larger (more effecient heat exchange and air flow) intercooler with larger pipes. This is always a good thing.

You could add water or propane injection to keep the engine cool but this isnt worth it.

Change the cam degree and the cam. A N/A engine is not properly cammed up for boost. I cant say off the top of my head what an m20 should be done but it shouldnt be that hard to find out. Just go to any boost site with a cam FAQ.

What motor do you have? What size turbo? How is it waste gated? How are you controling your boost? What kind/style pop-off valve do you have? What do you have to add more fuel? Do you have a pyrometer?
With out knowing this, if you have a 6 cyl, it already has 10:1 compression, I wouldn't advise anymore boost with out risking damage.

As far as fuel, you can run up to 6 pounds of boost on some stock fuel injection systems with out any major adjustments. And since you are going past 6 lb. of boost, you really need to get an air/fuel guage, if you don't have one. Even though this isn't the best way, it will let you know if you are running lean. And running lean will kill your turbo and motor.

I have plenty of experence with performance turbo motors, my most recent build was a 389 hp 2.0L in a 1995 eagle tallon. I may be able to help you.
