Oil System Number 2 - Oil cooler fittings and jet
This system can only be used with RPE billet dry sump pans.
Jet with 3mm diameter hole
There are two fittings on the engine oil cooler inlet and outlet ports, they are
either -8 or -10. In this case there is a restrictor jet with a 3mm hole located
behind the oil filter. The oil returning from the scavenge pump is pumped
directly back to the oil tank.
IMPORTANT
When using this oiling system, the jet behind the filter must have a hole
drilled in it.
IF THIS IS NOT DONE IT CAN RESULT IN ENGINE FAILURE.

This system is mainly used on the Radical SR4, as they have long hoses that
run to and from the oil cooler due to the radiator being mounted further
away from the engine than normal

is a solid bung.
