you need to put a twin piston type d/v on it not by the sounds of it a single type one! what's the make of the one you fitted?

 

Yep. My mates is exactly the same. Stick a single piston dump valve it stalls,
stick a twin piston dump valve on it it's fine. I've never tried a single piston dump valve on mine, but it runs just peachy with the Baileys twin piston dump valve.

 

hi there thanxs for gettin back to me peeps yeh i think its a single piston its a baileys got it off a mate who had it on a fiesta turbo thought it wud work the same

 

easy way to tell with a Bailey's twin type you'll see the piston/valve stuck up the middle of the tube!

 

got it sorted now twin piston works spot on
