Manual boost control (bleed valve?)
 

Hi, got told these can be dangerous and may cause car to overboost.......................anyone hear of it happening? in cabin controllers are just a lil bit outa my price rage at the moment...

thanks

We use one on each car that I've built, or been involved in building, and had only minimal problems with boost creeping. And those problems only ocured when we were about to max out the boost controller.

Even then the creep was minimal.

I reccomend buying an aftermarket boost guage, if you don't already have one, and just keeping an eye on it. Lay hard into the throttle with a budy in the car, and make sure neither of you see it creeping. If it doesn't, run it and keep a loose eye on it.


We could tell, easily, when the car went from pulling 10 PSI(on a Chevy Cavalier) to 13. I imagine you could tell in a Supra. I haven't modded mine yet.
