Andy, is this a sealed unit where the only crankcase breathing is through the pump (like a complete race setup) or is the PCV system still intact? Also did it build a good vacuum in the crankcase? I would have thought it to be worth a little more HP, but that may be all there is on a stock ring engine. I like the setup especially on a C5/6 where there is no room, or for someone wanting to keep the A/C. Good work!

The PCV system is scrapped and all crankcase breathing is through the pump. Both pumps sue an adjustable check-relief valve to regulate vacuum levels. The Performance model uses a separate relief valve while the race model has the adjustable relief valve built into the pump assembly, located between the inlet and outlet.
The typical street application will pull 5-7 of vacuum at cruising speeds and 12-14 of vacuum at WOT. However, crank the relief valve down and you can easily pull 22 of vacuum with the Performance model and nearly 30 with the Race model.
Higher vacuum levels definitely will put up serious HP gains but bear in mind thats applicable at the race track where as street use has limits that need to be adhered to.

Thanks for the info Charlie, I'm happy to see it built this way. I wouldn't run more than 14lbs on a stock engine, and some built engines don't need much more than that either.
