xpspensiv what are the advantage of drivers and what brand/style do you use? What do you mean by conveyor belt track? To the OP, I have been doing quite a bit of research on the ETEC mods. I can't get around the fact that most mods(except a turbo) only add a few horsepower(at most about 10%) at the cost of my warranty. As these guys are saying if you optimize what you have and pick the low hanging fruit like clutching and can you will have a great running sled that starts on the first pull every time and you won't have to worry about anything breaking that is not under warranty. I still can't believe that my insurance covers crash damage. Talk about a worry free toy. Motor blows, not my problem. Bend it around a tree, not my problem. Stolen out of my trailer, not my problem. I love this sport!:face-icon-small-ton
