Also, in this application, a cog belt design is superior to that of the serpentine belt because vacuum pumps can not take side loads. Besides, I don't think a serp is made that short.

JMX did some testing of an electric vaccum pump. At low speed it was able to pull vaccum. Under load it was unable to pull vaccum on the engine and saw no net benefit. This is a great idea, and a great addition to the LS1.

13"-15" is the max. recommended vacuum for any wet sump oiling system due to issues such as what GrannySShifting just mentioned. 30" shouldn't be a problem with a dry sump system such as on the new C6.
I for one don't think the price is out of line at all. If you've ever shopped for a vacuum pump you'll find you can't touch just the pump for less than $350. After you piece together all the fittings, pulley's, belt, etc. your up to $800 EASY. I know...I just installed one on my race car.

shouldaboughttheZ, go ahead and make say 750rwhp, and now try to make 800rwhp. Not that easy.
The price is kinda steep, I know if it were around 500-600 I'd be in for sure. What really bugs me is the kit doesn't include everything you need, you still need a catch-can :lame:

This can be used as a daily driver. I logged over 10k miles with the prototype and the pump remained as effective after 10k as the day it was installed.
That being said, my bet is that most people who buy a vacuum pump are high horsepower, limited annual mileage motors and of those, most will be large inch or ultra high revving stock stokes.

While I am ? on the price I am a firm believer in the vaccum pump...
I will probably have a moroso on it..
Esp when you build an engine with having one in mind.. LOW TENSION ring pack saves friction and seals better with a vaccum pump..
The combination of the low tension rings and 15" can be good for over 50hp in some cases.. Most of the time with regular rings 20hp... On forced induction engines more so towards 50hp...

Our pumps are competitively priced. We include all the mounting plates, bolts and hardware required to make this a 1 hour bolt-on.
Last, our pumps are the most compact and lightest vacuum pumps on the market.

I look forward to testing one of these out in the not so distant future to see where it can take us... This is a fantastic idea, and implementation. We've been looking at how to do apump, and up till now it was goingt o cost us an accessory which wasn't an option. This idea is simple, elegant, and functional.
Props to you guys for coming up with this...
