Thread: 41 Willys lifting at high speeds

The Link did not work Dave, I would love to read it.

the air follows the roof line all the way down the back of the car, and then rolls under the rear of the car creating an updraft under the cars rear end. Thats why you see these long wings on these pro mods and boxy cars, is to get the air back far enough to keep the air from getting under the car, as they were not aerodynamicaly designed to go that fast. And like Dave said earlier if there are issues with the way the cars weight is disstributed on the chassis, or susspension, this could be the real problem.

I was hanging out with a guy at the Goodguys Nationals one year getting tips for building my boxy anglia for speed. This guy had the same issue a year before @ 125 mph and rolled his anglia 5 times at the big end. He had just gotten it rebuilt and added the wing about 1/2 way down the rear of the car, and lengthened the chassis 10 inches. Right there in front of me, ive got pictures of it. He rolled the car 6 times at the big end again, thak god he walked away from it. Needless to say the car was destroyed.

This had me wondering and kinda freaked out, Im thinking I am not building my car like his. Maybe it was the cars susspension or scaled weight design I dont know. There was another guy with an anglia there that ran 160 mph in the 1/4 but his wing was on the back of the roof. And it was smooth sailing, so wing placement could be crucial if you try that route first. Either way you need to figure it out before you crash really bad. Good luck on your quest to figure this out.
