Right gotta get a new dump valve 4 my car.
Got an old original Bailey piston one at the mo, but it keeps siezing

Even on my older specs used to always split diaphragms so basicaly what do u guys recon is best on my car running 30psi on T4

Oh and if anyone got one for sale that would b suitable PM us would ya

Seen this one (pic below) adjustable boost setting so does that mean I could set it at say 20psi and the car would start dumping then so produce no more than 20 psi, and anyone had any experience of any like it
