Thanks for your input. To answer your questions, we are running these centrifugal compressors, like that on the compressor side of a turbo, at around 60,000 RPM. With that kind of speed and the compressor wheels we have designed, we are able to produce the 4.5 PSI at low flow. Some units we are in the process of testing have produced almost 5 PSI at 125 CFM with our electrical motors. Now to explain the bypass: The bypass we have used on an recent integra install was essentially a y pipe with a integrated check valve. When the unit it turned off the vacuum from the engine pulls the valve shut, due to wanting the path of least resistance, totally "bypassing" the compressor all toghether. On the integra install, we have tested the unit switched off and the bypass disabled and it lost 30 peak hp! I'll tell you that flat out. (Resistance and pressure loss) But with the bypass enabled there was ZERO net loss of HP. When it is time to make use of this device, the device turns on, builds pressure within 0.3 seconds and forces the bypass valve open blocking the regular intake and forces air to the engine. And of course when it shuts off the valve closes because of the path of least resistance again.

You are right. This product would not appeal to the drag racing world and auto cross for that matter since at 5K RPM the engine is requiring much more flow than the unit can deliver. This product is more suited for the daily driver or to cut out lag from turbos. To get out of the intersection.

Thanks again for your questions and concerns. We take a strong look at whatever we can here in order to improve these products.
