Ok, a year or so ago I purchased a couple of "grainger" valves with the part numbers right from Gus' and Gary's web sites. No problems there.
Now, last night I went to the track and used the method taught to me by James Reeves to set the g-valve off the car. I set it to 11/12 PSI to start opening with no issues.
The g-valve was installed with all new hoses, so no leaks there. The pressure tap was from the turbo outlet nipple, then to the g-valve, then straight to the WG.
On the track something wasnt right. I could only get 5-7 PSI on the track. I turned it in 1 turn, and tried again, no better. There wasnt much adjustment left in the g-valve at this point either. I thought maybe my WG was bad, so I took the g-valve out, and was able to boost up over 10 PSI while parked in the pits holding the brake, slipping the clutch (while sitting on GRASS!) ;)
So I ran the rest of the night with out the g-valve, just WG connected straight to a vacuum source running 5 - 7 psi.
It almost seems like the spring in the g-valve it to weak and is opening up almost immediatley, or it has an internal leak where the halves screw together maybe. Anyone have any ideas what may be wrong?
Anyway, my options now are (a) get the g-vavle figured out or (b) buy a premade manual boost controller that will work *before* I touch it!!
