Class rules - That makes alot of sense. If the powers at large will alow an external wet pump why not allow an external dry sump. I don't guess I will get to do any class racing with my street car because with what it costs to build this stage 2 project it is deffinately going to have a dry sump hanging off the side.
Maybe the powers that be don't have a drysump so they don't want anyone else having one to show them up. Silly reason, I know.
I have a racing buddy with an early Camaro. He is the type of person that will go to almost any extreme to make sure his car is the king of the track. A while back he purchased a Reher Morrison BBC. It did haul the mail. After 25 to 30 runs, it spun a rod bearing. He had ordered the engine model that included a wet sump pan. Original cost, $24,000 plus freight. The next upgrade model included a drysump setup. He cheaped out and got the wetsump. So what caused the rod bearing failure? He and some of his close friends were coming up with all kinds of reasons why the engine builder caused the failure. It then came out that he had been discussing a problem with his oil pressure with a mutual friend of mine. He was experiencing 0 (yes, that's zero) oil pressure on his gauge on de-accel, after the finish line. This is on the 1/8 mile, not the 1/4. Anyone with any sense would realize that you're going to lose an engine with that going on. Those of us with any mechanical sense realize that a dry sump system would have saved that very expensive engine.
Now. In order to keep racing cheap for everyone, the rules say 'no drysump'. How cheap is the racing for the fella that loses his engine because of a stupid, avoidable oiling short coming?
My friend with the Camaro is rebuilding the engine and is having another buddy modify the wetsump pan to fix the oiling problem. They hope anyway. Some people can be so thick headed. I guess it's the gambler in their blood. With all the money their spending to rebuild this engine after only 30 runs, they could have bought 4 or more drysump systems.
The kicker is, if you go to the Reher Morrison's website and check out their tech info page, there are at least 3 different articles stressing the importance of using a drysump system at a certain performance level.
