As you know my motor is a pure race motor converted to the street. As such it has no ability for a wet sump system. ie it HAS to use a dry sump. I use a Weaver 3 stage system that provides 55 psi at idle with 10/30 Mobil 1 (Hot) at 8,000 RPM it has 100psi.
I LOVE this system. I dropped my pan and took a look at the thrust bearing and some of the rod bearings. Like new with well over 100 runs and 3,000 street miles.
To protect against a failed belt (VERY RARE) I have a system that sounds a horn and Warning light at 50 psi. With that much pressure at the alert I, hopefully will be able to "save it".
Now a couple of comments on some of the others questions. A dry sump system can be used with normal
oil quantities. I "only" run 7 gts in mine so the tank is not large. Cooling is a non issue as my problem is trying to get the
oil temp above 150 or so. Oh and I LOVE my stainless #12 lines.
Also on the issue of cranking for the pressure. Think about it. There is very little compression with the throttle closed. So I crank it for about 5 seconds and get over 50psi then tap the throttle a couple of times (no choke) and it fires right up.
As I said I LOVE this system because it has so much more flow than a dry sump. At least in "Buick's" anyway
See you in September...
