I swapped a 7 horse Subaru onto one of our DBs a few months ago. We went through a couple of Comet clutches and finally decided to get a TAV2. I can tell you it definitely gives more torque. I weigh about 380 and with me sitting on the front edge of the seat, if I were to flat out lay into the throttle I'd be coming off. I've been trying to get some video, but I'm too scared of falling on my ass and really hurting something. I don't heal as fast as I did when I was 20. I did a super bad ass burn out the other day at my son's schools' park. I didn't know it was a wet spot and since it WAS grass, I figured why not, so I let in to it, and he was simply amazed that his big ass dad could do that, it was really funny. I got a good 30 foot burn out before it dried out enough to catch and start the front tire coming off the ground. It got about 5 inches off the ground for about 10 feet before I realized it. I imagine that set-up you got should be just as fun, good luck with it.
