New flywheel rule
 

Has NHRA come with a defined breakdown of the rule on flywheels (flexplates) other than all v8 stock and superstock.

I sure hope they will exempt my lo comp 340 combo, no starter gear ring at all. thanks Glen H

Hi Glen! NHRA's concern with these flexplates involves the starter ring gear flying apart. Now in the real world where people understand and realize what they're talking about and making rules for, if I need an SFI approved flexplate to ensure that my starter ring gear isn't going to break off and hurt a spectator then you and any other Mopar SHOULD have an SFI approved torque converter!

Talked to R. Silvy in NHRA tech dept. he said the stock/superstock commitee made the rule for flywheel(ring gear) . He said nothing he can do about it.I can submit a Email to him and he would pass it on .Also by rule book , superstreet is not required to have 29.1 flexplate. That is a 10.90 class. He would not give me any other people to talk to. Not a good system.

You can run 10.00 and 134 in a bracket car before you need an SFI approved flexplate but I need one in my high 12 second Stocker.
Common sense would dictate that a "safety" ruling such as this would be based on E.T., not Class.

My point also. What are mopar guys going to do ,the ring gear is part of torque coverter, and I can't find a sfi 29.1 torque converter.

Buy the adapter that bolts the convertor to the crank that has a sfi 29.1 number? Gray area?

Re: New flywheel rule
 

Mopars don’t rev high enough to break off the starter ring gear!

and neither does any of my lo/po GM stuff.

The rule is a Knee Jerk responce to a 1 in a million accident designed to protect them from law suits in the future,. My opinion Rick
