I responded to the poll with a no. I have seen what was left of a trans when they blow, but it never happened to me.
Im putting a clutchflite together here in the near future. It will have a good drum etc... I’ve been sold on that for a long time.
What I was thinking after reading through this thread though, is how can you know if the sprag failed without opening up the trans?(or having it open itself up) I had an A&A built 727 in the turbo car. I kept shearing pinions off of the rear end. The last one did some damage to the car( driveshaft whipping around) Anyway, after having that trans out a few times for inspection, I thought it would have been nice to know if the sprag is ok without going in.
Anyway.... since im going to be doing this trans, it would be pretty simple and cheap to install a drum speed sensor in the trans. With EFI, I can set my drum rotation limit to say 500 rpm higher than engine redline. If the drum exceedes that threshold, the ECU can shut down fuel/ ignition.
Good/ Bad/ Ugly? Anybody see a potential problem with doing this?
