Jay, isn't that part of the whole package? It can be two different cars, one with a 494, and one with the 493. Scale both cars prior and after each test. Tune on the clutches till each gets it's best run, bingo, question answered. Chris R.

In previous years, I had battery issues left and right. I bolted a second battery in, along with video equipment and was only at like 815. I don't really want to add weight either, part of the reason I don't want a 493. (there are about 3000 ($) other reasons too!)

I have a 1990 KBS Mk V with a 494 and even at nearly 220 I may have to add weight this season (in part because we remove the fire system in Solo) and we haven't really made a serious effort to reduce the weight of the car.
