High-Tech Nitrous

The LSx has an inherent flaw, oil ingestion into the intake manifold. Even N/A this is a problem, then add nitrous and it really shows it's ugly head. Just pull any intake TB off and stick your fingers into the hole and it will likely be covered with oil. The oil puddles on the plenum floor, then when getting on it, and especially when spraying, we see a lot of smoke out the tail pipe. Yes, we are burning this puddled oil. This is not good on a sprayed motor as it is a source of the dreaded detonation.

We have tried all of the fixes IE: puke cans, no PCV valve, big valve cover breathers, dual puke cans and so on. Only eliminating the PCV all together fixes the issue, but that leads to other problems, but we won't go into that at this time. Just don't seal off the PCV system all together for a street/strip motor. The real fix is a vacuum pump.

Until recently there was no good option for a street style pump, they all only lasted a couple hundred miles. But now due to the engineering at GZ, they use the oil mist in the blow by to lube the rotor blades in the unit for very long life. So know we have a true street/strip vacuum pump that can give us an additional 40hp at the wheels.

Watch for a full C5 how-to coming. I have all the info and have done the install, just need the time to put it together.

Here is the lead paragraph in the vacuum pump section:

[QUOTE] Want to stop the blow by from a lose nitrous motor, a turbo(s) set-up, or stop the nasty oil the LSx platform pulls in to the intake? Well, I have the answer for you, and the first dedicated kit for the Corvette and F-Body. Stay tuned, and read on, as I have the 2nd C5 model out on my test Z06, above. These pumps were designed for street applications and work as well at the strip. I chose to upgrade to the Pro Series pump due to a 300hp Dry N2O shot, and having larger than 400ci. See the sizing chart in the Application guide (quick links) if you think you may need a Pro Series Pump for big HP needs. [QUOTE]
