LS1 SFI Approved Flexplates IN STOCK!!
I got a quick question about it being light weight. For drag racing should the flexplate be so light? I once installed a light weight flywheel in my 6 speed, the engine rev'd very fast and was great on the streets but when it came to drag racing I lost alot of 60'.
I'm just curious if the lighter flexplate is good or bad for drag racing?
I'm currently running my 2nd stock flexplate. I even have a spare in the garage just incase this one breaks. If the TCS works out I will order one asap =)

FeartheLS1,
The flexplate weight is almost an insignificant (as long as it's not crazy heavy) performance factor because of a couple of reasons.
1. Unlike a manual transmission, a torque converter has torque multiplication to help you off the starting line. Torque multiplications of 2.0-2.5 are fairly common. If you take an engine that produces 400 lb ft of torque and multiply it by 2.5...you get 1000 lb ft of torque that is twisting the input shaft of the transmission. A manual transmission doesn't have this additional torque multiplication.
2. A flexplate is generally on the order of 1-2 lbs. It's sandwiched between a 45-50 lb crankshaft that has a 10-12 lb balance on the front of it and a 30 lb torque converter on it's backside.
You wouldn't notice the difference that a few ounces of flexplate weight would make.

This flexplate will be going in when I do the new converter =)
Thanks for the info.
