CDV mod done

well after reading about the benefits of removing the centre of the clutch delay valve I decided to give it a go

Amazed by how much difference it has made to gear changes and seems to have sorted out my cold weather clutch judder too so happy days,

One thing I wil say to anyone who does this is to turn and turn more the bleed screw it took me around 4 turns before the fluid came out its not like brake bleed where quarter turn is enough..

Well worth doing

This is probably the best mod I've done to mine drivability wise, also allowed me to launch harder at Santa Pod and made it much quicker between shifts, shaved a bit off my 1/4 mile times!

People have removed and aslong as you clamp the hose haven't bothered bleeding and it's been fine, it's a gamble cause if it does need bleeding and your not confident doing this your far is going Nowhere

possibly a stupid question but what does the cdv do and how does removing it improve the way the car drives?

I replaced mine with a modified bms one and bled it but didn't drive the car for a whole week. Not sure if it's me but I don't feel much of a difference lol
