theres cheap, fast, and reliable, you get to pick two. Cheap and superchargers usually go together like collard greens and chocolate syrup. Just because the kit is only 3000, there are so many other things that can go wrong that you have to be ready for. Not to discourage you, but if you are really going to have to budget everything you have to get just the kit, you've forgotten about the tune, extra money incase the worst happens. Now if it were me, Id have to go with the Cobra Killer kit. I dont think Tim has lost a motor yet. The kit is a little more expensive, but I wouldnt have it any other way. I also believe hes really into the Kenne Bells now too. Good luck, I hope im not to discouraging, If you want something bad enough, you will get it. So just work for it, save a little longer. And remember cheaper isnt always the best thing.
