RED initial Setup
« on: April 20, 2014, 04:37:35 AM »
Spud, I realize this may be out of your wheelhouse but I'm looking for some initial setup guidance for a RED. Chassis is 235 ",NA 380 ci 1025 hp @ 9800 rpm, 610+ lbft of torque around 8000-8200 rpm, pro flite 3 speed auto trans. Have gear sets for 2.09, 2.20,2.23 lows with 1.40 or 1.45 second gears. Tires available are 10.5 x33x15 (11.2" wide) 103 rollout, 12x33x15 (12.2" wide) 101.5 rollout, and 14.5x32x15 (14.5" wide) 102" rollout, wheels are 11",12" and 14" wide. Rear gears available are 4.71, 4.88,5.00, 5.29, 5.37. would like to keep the rpms down to 10,300. (10,000 initially)  Front to rear, weight distribution is estimated about 30/70 with the ability to move some ballast. I don't know whether 450 lbs frontend static weight  is enough to keep the nose from flying Less tha a foot or so. Run weight is 1530 lbs. My initial thoughts, using what I have are the 2.09/1.40 low/second (maybe could be a bit taller), 5.0 rear gear, the 32x14.5x15 tire on the 14" wide wheel. Launch at peak torque with a bunch of timing out of the motor. Have a 72" wheely bar, but don't want to run it unless we have too. Will run it initially just for safety. Will set it for a frontend lift of about 1 foot or so. Your thoughts?

 You're right, I'm not a chassis/drivetrain guy at all. I bet Roo Man could give you guidance on this!

 Or possibly some of our members...
