Changes needed for 1 or 1.5 mile
« on: January 13, 2016, 02:45:45 PM »
How much weight should be run in a roadster at the mile or mile and a half courses?  Right now I'm about 4000# and I know that's too heavy.

Life is an abrasive. Whether you get ground away or polished to a shine depends on what you are made of.

Weight is not your friend on shorter courses. The shorter the course the more weight matters. I would remove all the removable ballast. If you are spinning the tire a lot put some back in the back.

At Bville you add weight to speed it up until it starts slowing down to find the right weight. I would try the reverse of that but not set up a 1/4 mile drag race CG.

Hi Sid
That sounds like Dolan's, add gear till you slow down, then add horsepower. :-D :-D

Davidson considers 4000 pounds too light to run 1.3 miles.

Maybe the answer depends on the roadster's horsepower to some degree.

A lot of it depends on what course you are talking about, pavement is a lot different then dirt or salt.
