Good luck in your quest...

“In a 600-800 horsepower engine, the combination of crankcase vacuum, improved ring seal, and low-tension rings can net between 15-25 extra hp. Even on an engine with rings that haven’t been optimized for a vacuum pump, you can pick up at least 10-15 hp.”

Although an increase, it just doesn't seem worth the effort for such small gains especially not when working with a SC imho.
