Adjusting BOV
I have a Greddy Type R BOV on my car, just curious to know if I have it adjusted correctly. It shouldn't bleed any boost, except when the throttle is closed, right?
I think I had it too loose, because I tightened down the adjustment screw today pretty good (about 1/2" of thread left now), and prior to this when I was getting on it you could hear a pretty loud whoosh noise from under the hood. Now the noise is gone, and the boost seems to come on a little sooner. The wastegates seem to be working at the same 11.3 psi, so I feel like I was probably spooling the twins up to 15 psi or so, and bleeding it out of the BOV. It still works fine when the throttle is closed...
But now I can come off the line in 2nd gear and roast the tires.. gotta love boost.
Now to get the pipes coated (if the guy will ever call me back! dangit!) and then get it to the track....
More news as it happens
