I guess that I'm confused about this process. Won't there be a time of comment before changing any of these rules? We didn't even ask for a weight break for 440s. And because a few guys ask and write for porting for kaws the weight get changed? Sorry but I didn't imagine rule changes would work like this. Dave Panuef has already worked on Ti brake rotors and such. This weight change may be well intentioned for bringing out old cars but aside from the no suspension era cars, I doubt you could chase 100 lbs out of a chassis without compromising safety or greatly increasing the use of exotic (expensive) materials. Just my opinion. John Whitling Stan wrote:
We dropped the weight to 700 lbs after considering all the input on the subject , especially that from the Kawi guys. Neither porting nor overboring was consid ered a workable solution, and since many of the cars which came with those engi nes date from when the minimum weight was 700 lbs, we felt that the best choice available was to revert to that weight. The change isn't going to make the Kaw i a Rotax-killer, but maybe it'll bring some cars out of garages and get them b ack into road racing.

First of all, it is not that easy to lose 50 lbs. Just ask anyone on a diet ! All of the cars out there are designed to weigh 750 with a reasonable weight driver. I don't see how you can get a car down to the 700 lb mark and not reduce the structural integrity. When I first raced my F500 with the Kawasaki, I had to add ballast. That all changed with the change over to four link suspension and the added bodywork to get the aero working. I am not the familiar with the new chassis, but I suspect they are all being designed for the 493 engine and thus would not be able to get down to the 700 lb min. Just one more small change, allow increasing the compression ratio to about 9:1 on the Kawasaki. This would be so easy, just mill some metal off the head, reshape the dome, and presto, a 90 HP Kawasaki ! Ofcourse some clever chassis designer, Jay are you listing ?, could build a new chassis just for the Kawasaki using all the improvements learned over the years, but apply it to a car designed for a engine from yesteryear.
