I'm running a dry sump on this motor. I really like the dry sump setup. It is so much easier to dial in a dry sump and the engine oiling is a lot better. Hate to go back to a wet sump design after working with a dry sump.
Andy, why are you running breathers ?
Chuck, I fabricated some adapters so I could run a Moroso vacuum relief valve as well as a vacuum gauge in the other valve cover. We made a bunch of dyno pulls with this setup and didn't see any power difference or any vacuum in the valve covers. We did see more oil leaks though so I'm going to go back to the breathers. My guess is that this little 3 stage dry sump pump just doesn't have the beans to pull a vacuum on this motor. I'll probably step up to a new 5 stage pump later this year so then I'll run the experiment again.
