Oh boy! that was hard to watch... Is this just the syncros? Or is the shifter at fault as well??
I believe it’s just the synchros but with every missed shift the ratchet in the shifter selects another gear and you end up in 4th or 5th or 6th, then you have to shift it back down and grind them all over again looking for 3rd.

The guy operating the dyno didn't know how to use it properly and it was pretty ugly there for a minute....he let me back it down off the dyno after that.

The guy thought the transmission was sequential and its not just a sequential shifter, so he ran threw a handful of gears without using the clutch and ground some gears

I remember back in the early 80s when Foyt showed up at Daytona about halfway through the race. A team put him in one of their 935s. He'd never drove one and asked if it was a 4 speed.. it was. He was ridiculed for it, but then he ran some of the fastest race laps in the event. It never hurts to ask.

How many race weekends did you get out of the Magnum XL? Also, on the bad call that moved you to the back of the pack was this initiated by a race official or did another driver lodge a complaint? I am just curious since I haven't raced w2w and I'm still learning how these things work.

The first one lasted quite a while with the blown 3v and is still going strong in another car but the second one started having issues half way through the first season with the coyote. Probably because I wind this motor so tight....I don't think that trans is designed for 8200 rpm shifts. As for the flag, an official brought it to my attention in impound.

If / when you have it rebuilt, upgrading the blockers and synchros, installing bronze shift pads, shifter bushings, polishing the intervals are a good idea. Liberty Gear does good work and bundles this and some other improvements as a package. But, turn around is 3 - 5 months. Of course, they also do faceplating….

Mine has been going strong since 2015, but I usually shift at 7,500 and occasionally at 7,800.
