Flexplates-Aluminum vs Steel??
I have two flexplates at my disposal and am wondering which I should use for my setup.
The car is a 98 Formula, full race, 10pt chromoly cage, 30" rear hoosier 315/60/15s, Moser 9" w/ 4.56 gears, 40 spline axles, full spool, fully built TH350, trans break, Forged 347ci LS1, 235/340 cam, Lingenfelter 2 step, AFCO radiator, motor plate, on a 200 shot it should make 600-650 rwhp or so.
The two flexplates I have are a steel TCI and a CSR aluminum with bolt on steel ring gear. The CSR weighs 5.8 lbs and im not sure on the weight of teh TCI.
This car is full race, logic would tell me that the aluminum is better, obviously its lighter and will reduce rotating weight but I dont want to put it in if I may have trouble with it, so im wondering more if any of you have had trouble with these aluminum flexplates.
Thanks alot!

Is there any logic behind steel (heavy) flexplates being better for drag? As I see it, once you bring the revs up (let's say, to 3600rpm), you launch and revs never drop below 3600, so heavy flexplate does not give back to the converter any stored energy, right?
On the other hand, on the street lightweight flexplate would be nicer because when you press pedal it brings the engine to stall rpms faster. Actually on the strip too engine will rev from 3600 to shift point faster with light flex.
Am I wrong somewhere?
