How much Boost on Stock Internals?

abhattan · 01-26-2007, 12:28 AM

Hello guys, thanks for the help with the "Not Holding Boost". It turned out it was bad ignition wires. Got hot, and got bad. Anyway, I have an open air filter and a 3" exhaust from my downpipe back. I also have an NPR intercooler. I am about to put in a boost controller and was wondering what is the highest amount of boos I can push on that set up? Also, I will be installing a 2mm MHG soon after. What about then?

Probly a decent 12-14psi
But be sure the engine is running healthy
Beyond any doubt b4 boosting the car

A new fuel pump, and an afc to control it should be your next mods in the list

What's an AFC? I was thinking about putting in a VPC and GCC with a set of 580cc injectors, but not for another few months.

So that means that between 10-14 psi, the fuel will cut out? Why at that point? Is it some kind of protection?
