Vent?

yea drill/cut some holes in that body to release air going underneath the body. Works on my camaro body. You need to follow what the dragracers are doing and kinda corporate some of the ideas into your speed demon.

I had blowovers at around 57mph before and the last time I ran the camaro with a few holes in it, I had no blowover at 67mph. This Saturday I will see what I can get out of the body with an extra cell.

Yea, I already cut the back of the body:



I could put 1,000 holes in the body or not even run a body and it would still blow over. Its the positive angle of attack of the chassis that caused my blow over. The chassis plate was acting like a wing. The rear of the car was scraping the ground and the front of the chassis was much higher than the back. I wasn't expecting to get these speeds so I didn't change the suspension much from stock. I need to put stiffer springs in back and play with the ride height to keep the chassis level or at a negative angle of attack to the oncoming air.
