Specs on our motor are;
433BBC..11.3:1 Compression with an Affordable Fuel Injection 1000 cfm multi port fuel injection.. I have to update the specs on our page....It has been on the rear wheel dyno and has come back as max power 476.9 hp at 5900 rpm and 440.2 ft lbs of torque at 3600 rpm..that was on a 150 shot of nitrous.. We are now using 180 shot...
I'm not sure on the specs of Folks engine Demon.. but I believe he has a 770 cfm Avenger carb and runs on pump gas... we run ours on motorsport 109....
We are happy with ours and that's what counts to us...
