In this customer testimonial, the owner describes why he likes it:

"I mounted it on a piece of aluminum and installed it on the outlet side of my Vortech aftercooler. I also use you’re impeller and it also is great I was pushing 14# of boost at 5400RPM, too much for a stock engine especially in cold weather, so I set the boost control valve at 10# before I installed it and I am reading 11# on my Autometer electric boost gage with memory. The valve operates quietly and my air/fuels are stable through the dump cycle, this is a terrific device no lost low end boost and no fear of engine damage, I will fine tune it for 10# as per my Tuners instructions. Possibly this will help someone else using a similar set up. "

We are at 4400' elevation in the valley, up to an easy 10k' if you like playing in the mountains. We have to overdo everything up here to get any kind of performance. I am sure Carl can attest to that after his Pike's Peak excursion, I'll bet he thought his car felt pretty flat at 12k'...

I think that it's a good idea brought to market, I will probably use his now due to the ease of adjustability.

Hmmm... I have been looking for a way to be able to put the throttle plates after my Lysholm blower and not having to fear pressure spikes. It is possible to have a valve that just vent the pressurised air back in front of the suprcharger (or into free air) but if this system fails, or simply are too slow, the pressure between the supercharger and throttle plate will rise to the point where the lobes in the supercharger meet...

From Corky Bell in his book Supercharged:
"A technique for blowing into the throttle with fixed-displacement superchargers has been developed but is not yet available in the aftermarket.

Certainly, in many circumstances, including a bypass valve will be easier than relocating the throttle. However, the closer the throttle is to the intake valves, more crisply and responsive an engine will run. It is currently popular to use the bypass, yet leave the throttle in front of the blower"

I am not sure if these valves react quick enough, and I am nut sure I want to be the first to try, but it sure sounds like a couple of these might do the trick...
