I run the remote filter and the oil flow is as follows: plate, filter, cooler, back to plate and to the main oil gallery where the pressure port is located and the PRV. The major restriction is the oil filter, period. That is why I run a Canton or Oberg because it impedes the oil flow the least. (Canton advertises oil flow equal to three Fram filters in parallel.) We want good oil pressure but we also want flow. So, the less restriction we can engineer into the oil path, the better. Jim’s idea is very good, except he does not use an external filter. Adding -10 lines and a remote filter and cooler will do next to nothing in regards to oil pressure/flow. It just makes good sense for the health of your motor.
A side note: the Cup guys have gone away from the Oberg to a Fram racing filter. They have determined that a 27 micron filter gives them the best flow through the motor, and anything smaller will not hurt the motor. Check under the hood next Cup race and see the orange Fram filter. CB
