But if you do the google search you will see that there is a company that is selling a DC 12volt driven Roots blower AKA real super charger for about 1500$.
Yes, that would be Thomas Knight who owns boosthead.com down in Miami. He has been playing around with positive displacement blowers for a long time. I've seen some anecdotal evidence that some folks don't get what they thought they were buying from him - not in the case of the electric supercharger, but with some of his prior Roots kits. As an example, when I started research for my own engine ideas, I had an email exchange with him and he sent a couple of pictures which I still have and can post, but I just wasn't impressed with the quality of work. His electric supercharger is a good idea for drag racers and probably works just fine as it was intended - BUT - it doesn't make a lot of sense to me to put a bunch of batteries in the trunk and charge them for several hours for only a 10 second run of the blower. <img src="/forums/images/graemlins/scared.gif" alt="" />
It never hurts to dream a little, though. That's why I like the idea of the compressed methane gas with multiple sequential nozzle discharges. You could use it for climbing obstacles or hils and for acceleration on the straightaway. I think I'll patent it and license it to General Motors. We could call it the Fast Ascent/Rapid Traverse system...... or just by the acronym abbreviation....... F.A.R.T. <img src="/forums/images/graemlins/lol.gif" alt="" />
Or - it might be easier to install a nitrous system.
