Lightweight flywheel options and selection criteria.

Well I might as well get into this aluminum flywheel argument. I,ve been running aluminum flywheels on both of my cars for years now. Like Newbomb Turk said heavy flywheels and on off clutches should have been left back in the 60,s. My Dart is a 4 spd Jerico and weighs in at just over 3400# in race weight and will carry the front end out at least a car length another car length or so pass that it is in second gear another car length and it crosses the 60 foot clock (best 60 foot 1.46). Thats with a 18# alu. flywheel, sintered iron disc, and a long pressure plate with an aluminum pressure ring, my whole clutch set up is probably lighter than the pressure plates most of you guys run. My Dart is a street car it gets run through the exhaust out to the factory exhaust tips( wrong for my year, but so is dual exhaust). Tried a small Drag and Drive this past fall, after driving about a 170 miles to an 1/8 mile track. My son and I let the Dart cool down while we switched from street tires to the M/T 9 28 slicks and unloaded the tools, jack, jack stands and spare parts out of the car. The Dart ran a 6.75, 6.74, 6.82, and a 6.74, the 3 .70's were high 1.4 60' the .82 spun to a 1.53 60'. the 1/4 mile track the Dart ran in the 10.6 to 10.7 We got a second place plack for most consistent car, first place car was a newer 5.0 Mustang GT with a 10 speed automatic, he ran with in a few 10 thousands of a second on every pass 1/8 and 1/4.
As far as driving a heavy car on the street with an aluminum flywheel, I have one in my 2012 Challenger R/T Classic, the 5.7 Hemi is making just north of 400 hp to the rear wheels with a cam, 6.4 intake, 1 7/8 long tube headers. The car from a 2500 rpm roll in first gear will snap the tires loose and does not catch traction till mid third gear, not bad for a 4300+ pound car with 6 spd Tremec and 275 45 20 tires on the back and a 18# flywheel.
