but if you have 2 tb's how would you get away with just 1 icv?

and the manifold would cost more than £100 in bits easily...

because that way both icv's will open the same amount as 1 would, meaning each set of 2 cylinders will get too much air, would need to find a way to cut down the signal from the ecu. dastek unichip would be good.

TBH in my defence it's a bit of the pikey showing through, but more interest in trying to get better gains than from the mantzel without going the whole hog of a TB set up .

Yes, nitrous is a quick and cheap way of increasing power, but i think your missing the point here .

I'm just trying to point out that i think theres a big gap between the performance of a mantzel type uper manifold, and a full-on TB type system.

The way some people are so dissmissive at times it's as if were working on state of the art F1 engines here, not cheap performance per pound improvements on mass production engines like i seem to be talking about .
