Forget the sound issue, I like it and (no offence > intended here) I don't care whether you do or don't.

It didn't make the "ptttttttsh" like the SARD I have on the Celica does, but it did make a polite "Cough" noise on gear shifts, sometimes louder than others. The SARD makes a real Woosh noise. If you find a double piston dump valve you may be OK with an Atmo. I know the Celica had a flap rather than hotwire AFM, and it works fine with the SARD. Other people have used Bailey and Forge Atmos DVs, I think the Bailey to use is the DV 26 (especially the D type, although ISTR that the DV36 is louder. DV30 is the recirc. Some people say that the Bailey gums up and stops working though. -- Carl Robson Car PC Build starts again. Homepage:
