wot is the best dump valve to get for the focus rs
is the graham goode racing piston type one good or is there better

 

Bailey DV30 recirc

 

how much are they mate

 

Paid £88.50 for mine from SCC Performance matey.

They are the best

 

I would say stick with a recirc dv - Bailey DV30, Forge007 or the standard recirc - an atmos dv will make your car overfuel and you may also suffer from stalling when changing gear - plus as i found the noise of the atmos dv will get on your nerves after a few months and you'll want to go back to recirc anyway
