Well I got a chance to give the car a wee run on the dyno today with the spring tightens down a bit more and that is deffy the problem got full boost by 3500 rpm there does apear to be a few new problems tho one is to get the valve to seal the exhaust properly I'm boosting at 11 or 12 psi more than I want !!! The wastgate I think is a cheepo the valve the closes the exhaust isent actually fixed within the valve but the idea is the valve actually seals down onto the Exaust manifold it's self but neither are completely flat so it's never going to have a perfect seal even with plenty pressure pushing down on it not sure how important this is !! Other problem is iv got a blow between the head and Manifold again the prob is the manifold ain't perfecty flat so ordered a thicker gasket hopfuly do the trick . Couldn't give it much of a run in the dyno as the AFR is now all wrong just not sure what to do about this wastgate do some seal within thereselfs or do all seal to the manifold ?
