Finally got this problem sorted out and thoroughly tested...

Find a way to secure your Empeg's handle when it's in it's sled and I bet you'll solve the problem.


That was the trick. A very thin strip of velcro along the back side of the handle totally stops it from moving with force pressed from the hooks. Placing it at the bottom of the handle gives it a fair mechanical advantage as it is a long lever compared to the hooks above the handle. Plus, lifting the handle means you're pulling against hte velcro directly so it comes apart easily.

This solution stood up to a full day of sprint testing recently. Lots of max acceleration standing starts in the dry, and no loss of Empeg.

Not sure why I didn't think of Velcro before. I use it to hold the rest of the car together already. Handy stuff.
