Like I said they look the same, but that's were it ends.
Have you ever considered the crank in a chain car is half the wieght? We all can do the math on the acceleration rate vs the 2.
And yes same chassis, but put the 2 cars on a scale, percentages are night and day.
And don't tell me that doesn't matter, why do you think in the taxi cab world the under hp motors get more left side weight?
You see results of the snow ball derby?
Winning car was dqed for 0.3% allowable left side weight. And on a slick track that makes a huge difference.
Again results speak for themselves.
Look at the big D2 race in October, at Jacksonville.
Top 4 out of 5 were chain cars on a track that looked like an ice rink.
4th place car, a man with more experience than every competitor out there combined, with a non legal D2 drive shaft car could not touch the chain cars.
His motor is a badger K 2.4L, not allowed by D2 rules.
Facts are facts, you can twist the truth any way you wish, but there is no logical argument for chains n shafts to compete together other than make car count #s look better.
