I have no idea how you did it, but I'm not gonna call BS (strangerr things have happened). As for the 18/52 sucking as far as hole shots and power, I think alot has to do with the gear ratio between the crank and the tranny input. I was going to run a 17/49, but due to a number of factors, I had to use a Mugen flywheel from a buggy. Unfortunately, the FW has a bigger diameter on it than the 4 shoe I was going to use, and when I put the 17t CB on, the FW rubs the TVP. So I had to drop back to a 15t CB. I used to run a 16/52 ratio on my Picco 26, but now am running a 15/49. The ratio is almost the same, but the new ratio is crazy as far as wheelies and torque. Before, I had to really lean it up to get the same results. It's still as fast as before, but the on demand power has gone up consierably. If I can get another FW nut, I'll probably put the 4 shoe FW on and run 17/49.
