Cheers You 2... More than explained it. Just came across it and have seen a few and heard about spacing out the plenum, just wondered what it did and if it was worth it with the Power i will have in a month or so.

I will put my £45, to a carbon Fibre Idea i have instead...

Ben, yeh i am changing my Housing to a .48, but will be after i have the greens, 3 bar etc etc and clutch, then prob do the .48 housing along with 2wd manifold.

All im aiming for is a Solid 330, as i still want drivabilty as well as reliability... I know thats hard to come by, but im only subject to the odd track session here or there and a few runs at the Pod, so i dont have to go mad as 330 will be more than enough for the road.
