When doing the exhaust the other night I checked a few temperatures around the engine and was surprised to see the intake manifold was the same tempreature as the cylinder head due to thermal conduction through the gasket.
As it seems a shame to cool the charged air down with the intercooler, then heat it back up again with the manifold I wondered about making a manifold gasket from phelonic material as this should reduce conductivity by 200-1000 times depending on thickness, thus reducing the charge air temperature and cylinder filling for the same, or actually slightly less boost pressure.
Does anyone know of a supplier for small pieces of phelonic board (or similar thermal insulant), and even someone to do the machining.?
TIA.
