I was just curious if these trucks can benefit from one? I had a buddy of mine use them on his mustangs when he turboed them and gave one to me a long time ago. Can I use it on my cummins?
thanks

 

Uhhhhh....What's a grainger valve?

 

Your wastegate is computer controlled, so I'm not sure that a grainger valve will do you much good. I also think that you may set an overboost code if you're not careful.

 

the spring in the valve is a little light for the boost we run too... it would need to be shimmed quite a bit to pop open at around 25-30psi anyways...


the "grainger valve" is an adjustable pressure relief valve that has been home modified a bit last item on this page is the valve from mcmaster-carr. same valve basically

 

Thanks. They look and kind of sound like what's on the top of my KTM's forks, mounted there to relieve the pressure from the forks after a long days ride.
