My weight was just a guess so with this input from owners I would think another 100 lbs at least could come off so we are at 2850 without a driver. We are starting from scratch so lets build a 72 Demon and take advantage of the snorkle scoop for some fresh air. A 416 inch engine should be able to make 1.15 Hp per cubic inch fairly easily which is 475 flywheel Hp. So with a 200 lbs driver we have a 3050 lbs car with 475-500 Hp. Your launching this 3050 lbs car on the same tire and wheel size that HemiJoel has run 10's on in a car that weighs at least 600 lbs more than this Demon. Could get very interesting. This package with 500 Hp and a 1.60 60'might run a 10.
