Put the Duster on the DYNO.

Its just a drag car. All steel except bumpers and hood, all gutted including aluminum dash, 1 race seat. All Lexan. Trunk lid is also gutted. No front inner fenders. It is pretty much gutted all over. Even the headlights, just stickers.

Ah, okay. I thought it might have been the green one in the avatar.

With that much weight cut out it will be pretty light. Does your track have scales?
