So many to choose from, ! whats best? there are single piston dumps, twin piston dumps and also ones that say are for use with AFM and ones without.. whats the difference between single piston and twin? im after a louder Whooosh than what ive already got from a old school baileys.. im guessing the twin piston is the one to go for? am i right? and do i need one with a trumpet?

I've heard the HKS "fast & furious" style BOV is the one to have

I'm using a 38mm i/d horn style BOV, loud it is

quite cheap too.

The bailey ones seem to not like the amount of air us M20 owners are shoving through them, Ants old one would dump on cranking!

Get one from an Audi and stick a 'fart whistle' on the outlet.
