all the best cooter and let us know how you go..

If you could get more air into the cylinders (turbo and intercooler influence this), the EGT would be lower with the same amount of fuel.

cheers for the advise i will still be upping my boost to 17psi but will not be upgrading the ic to another air to air would not be beneficially instead i would prefer water to air running a seperate cooling system for the aftercooler
first have to replace my broken rocker shaft
