Just a post to see if anyone has ever used one and to see what the increases in power were?

The principal behind it is that you put a small electrically powered vacuum pump to pull the air from the crankcase and this means that there is a lot less resistance for the pistons moving in the cylinders and so you gain power right across the rev range.

It's used in F1 and quite a lot of other racing applications and I wondered if anyone on here had used them?

A friend of mine races Formula Vee and one of his competitors has tried this system to good effect, average bhp from a Vee engine is 90hp - with this mod and a couple of other "special" tweaks over 100hp has been achieved. (N/A 1300 Beetle engine in case anyone wondered)

where can you buy this system from. I will invest in one and give it a try.
