Not for me,honest lol. Lad at work has built up a few years no claims and is toying with the idea of getting a cheap S2. He was asking me the diffence between a Bailey DV24 single piston and DV26 twin piston dump valve. I don't know so thought i would ask you guys. cheeRS.

 

just admitt the question is for you

nothing wrong with a dump valve

 

lol. He is a bit of boy racer but does look after his cars to be honest. He wants to fit a DV if he gets his S2 but wants to know which one is best for the S2. I think the twin piston is less likely to incur running problems but not sure

 

the mfi system on a standard S2 needs to be sealed airtight for the metering head to work properly so putting a normal single piston DV it would run shit as if it had an air leak because single piston DVs stay open when under vacuum, the twin piston still opens under vacuum but seals the pipe so the metering head works properly opening fully when under boost/blowing off

 

cheeRS bud. I will pass that on to me. . . i mean him ! lol

 

as Joe says, when buying one just make sure he gets one for an Mfi engine

 

I have a Silver DV26 for sale. £35 posted.
