Morris,
Oil system plumbing ideas:
I have a 3 stage Peterson pump with two -12 scavenge ports and was intending on running "one -12 scavenge line" back to the
oil tank, and the other -12 scavenge line via a Peterson Bypass valve to an
oil cooler then to the Oil Tank, and the -10 bypass "relief valve" line to tank, that means fitting an extra two fittings to the tank as there is one -16 tank port. I also have a scavenge manifold with a -16 exit fitting and could run that through the -12 bypass valve to cooler and excess pressure would take the -10 bypass circuit to the oil tank, but I am not sure of the flow rate of that and that would mean blocking the oil cooler off manually!
Another idea is to use a Canton T/stat on one -12 scavenge circuit, then to the oil cooler, the other -12 circuit straight to tank, this thinking in my opinion is better than having a manifold down to one single -12 line to T/stat where all my scavenge oil has to pass, with two lines it will have an adequate flow rate.
We will be using an external tank heater before use so the oil will be heated, I am not a fan of cooling the oil pressure side, and really the only reason I am contemplating a T/stat or Bypass valve is to avoid blown oil coolers on start up, with cold thick oil in the pan hydraulicing its way through the cooler, but having said that the oil flow with the Canton uses the easiest path so on startup it will still send some oil through the cooler but shouldnt be an issue.
Quite a few racers run coolers on the scavenge without pressure relief and get away with it but I have seen F5000 race cars start up and blow coolers because of the scavenge oil pressure or pulse is worse even though the cooler is open ended.
All that sounds complicated for a street racer.........!
