are the above statements saying neutral drops don't affect the sprag ? what fails internally when neutral drops are stupidly done ? or am i not understanding something in these statements ?  Do a few, then try looking thru the broken parts to find out what broke first. It was a starting line practice back in the sixtys but the tires where tiny. NHRA banned it after too many clean ups. Then the billion dollar converter industry came about. a few ? man, i remember this technique like it was yesterday ! then, there was the practice of us doing "J hooks", where one would go real fast in reverse, then drop into low. object was to see who could male the longest "J".  funny we all have any feet left ! the local gas station made a fortune selling us used goodyear and firestone red line [and occasionally blue line/blue streak goodyears] G-70 tires for $5.00 ea [mounted and balanced - dating myself ?  ]. at least one pair of tires per weekend, not uncommon though, to go through one set per night ! we sure were "young & dumb" then. luck on our side helped a bunch too......

And yet the Super Sprag fails too. Here's a pic of an A&A sprag that failed recently, notice all the pins are straight.
And the kicker, the trans was working "just fine" according to the owner but was pulled because of no Reverse; on disassembly the pan was found to be full of hard debris, further disassembly found the grenaded sprag which took out the roller rear support, rear band drum and the case. If it hadn't been for a broken factory rear servo piston the owner would have attempted another run.
Griner transbrake VB with no LBA and a factory front drum.

Can you imagine those tires on today's hot cars? We did a trick with the neutral safety switch, ground the switch, floor it, then start the engine. Probably didn't really do much but felt like a high stall converter or at least what we thought it would feel like. It is a wonder we lived to tell the tales. Racing and hanging out around the Hot Shops all Friday and Saturday nite, those where the days, er nights! $10-15 could last all weekend.
