Can any one explain what a Grainger valve does?

[Realspool]

Some guy mentioned it to me and he told me it makes the car feel like your driving a V8.I love the Turbo 6 but if this were true the feel of the car would feel better i would think?I don't know where the part is installed but i remember him telling me its something about a ball that creates the V8 feel.Hope any one can explain to me what this part actually does and is it such a dramatic affect on the feel of the engine?I have a racegate with a TE-44 turbo that does not spool all that well but, i have exhaust leaks and I am fixing that right now.Just wondering about this valve if i spelled it correctly not to confuse any one

bleed me

Hi

I am not sure but I think it bleeds wastegate pressure. A friend and I put a fish tank valve on his Volvo 760 turbo and the thing screamed!!! This thing just bleeded the pressure going to the wastegate so in theory it would not open the wastegate all the way.

If you needed 5 psi to open it normally, it would only get 2.

He left it on when he traded it it, I wonder how the next person felt when the test drove it!


we referred to it (the fishtank valve) as the "Horsepower Screw"

What the grainger style valve does is it slows down air to thewastegate acuater & keeps the wastegate closed longer which allows boost to come on faster.They claim boost comes on 600 rpm's sooner. I built a few of my own and have different springs in them. If you want one $23 shipped.
