And like the famous Monty Python Sketch (or was it "Not the 9 O'Clock News"), I have a "Machine that Goes 'Ptttsch'".
Have it loosened off quite far, but it will dump on each gear shift when the factory gauge shows Atmos pressure, rather than full boost. Am planning on adjusting it so that it will only dump with at least 50% boost.
BTW Chet. Full boost in first and second is 6PSI, and 8PSI in the other gears. It dumps nicely.
At full boost it gives a quiet (in the cabin) but very long Ptttttsch. Probably far louder outside, will have to try it with the window open.
BTW Vamp, no problems with idling, or black smoke on gear changes, so it seems to work with the AFM. One thing, if you get one for the Tubby, make sure the T piece you get is a 30mm one, I had a real pig of a job installing mine, because the T piece is a standard 25mm, and the DV is a
30mm. Doable, but really nasty to do.Car is much smoother on changes now.
