  Have been looking forward to  improving the Sunbeam race car.  Been 
thinking out loud on several  issues of dry sump systems and the 
pressure side oiling .   I like the dry sumps use in the sunbeam because 
I can keep the engine lower down between the frame rails.  One of the 
items that has surfaced in my head is the use of an external oil 
pressure regulator system. Huh? you say.  Most of the oil pumps we use 
have an internal pressure relief system  but unfortunately it is right 
at the beginning of the pressure input. The oil is bypassed around and 
around inside the pump and it gets hot. The bypass should be at the end 
of the oiling system path to assure that each and every thing that needs 
oil, gets oil.  Plus, the oil would not be chased around and around 
inside the pump. This should work exactly like the pressure regulator on 
an EFI car with a bypass return system.  The regulator should be 
adjustable. I have a large Aeromotive bypass regulator on my fuel system 
and that sucker might be able to do the trick.  Have any of you ever 
heard of using an external oil regulator bypass like this before?  I 
have not, but then I am still a noob at this.

The next is some sort of scavenge system. I know the corvette now has a 
dry sump system which means that it has to have some sort of scavenging 
system to return oil to the tank.  Anybody know how that is done on that 
car? Point me to a URL where I can read about it?  Would a vane type 
pump serve as a scavenge return pump?  I would also like to hook up the 
scavenge pump to the valve covers, on each side front and rear, and 
maybe the lifter valley as well ll in support of getting oil from the 
pan as well.


I would love to hear thoughts on a system or issues like I mention.  
Either on list or off.

headed up to Bendover in the morning around 4 am....ugh...
