Got Ya Bill,
George ( down under)
I believe the thermal pallet is designed to allow some of
the cold thicker
oil to flow through the e-shaft bleed hole until the pallet
heats up and
seals off the hole - which forces ALL heated oil to flow through
the
journals. The 12A doesn't have this function, so I'm debating on whether
to
include it or not (in the single rotor) OR just seal the end of the
oil
passage as in the 12A.
George,
I have built many racing engines with at most a blow off valve for high
pressure. You must be carefull not to race the engine when cold or you can
damage something. I have exploded several oil filter canisters. Some type of
bypass prevents operator error. If anybody but you will ever run the engine
building somekind of idiot proofing is a good idea.
