Hoffmans took 200hp out last year with the V8 and Smoke said it still had more than enough. This year they went V6 and Eric Gordon was up to fifth. Something in the drive line, a bearing or something went bad. Dan who was their full time Mechanic said most of their cars were over weight as you need stronger parts in certain places. It's why the top teams have very few DNF's I know on the pavement car the drag link was two pieces connected by rod ends because a single drag link bent so far the car wouldn't turn due to the forces on Pavement.
BTW Dan was working on Kody's car
