Power to Wt. Graph for some factory special runs
 

Upper Lefthand corner = good

Lower Righhand corner = bad

I connected the dots since there is a general flow with time in the graph too...

I think the light weight cars were the best but there is still a chance to recreate a 2,500LB car with a 250 HP engine and more modern wheel/tire and suspension. A more ridgid body and better balance will certainly help all types of handling...I would like to see a "how to" article on basic improvements for both wieght and HP along with better handling. Everyone on this site is doing this on their own but are they right?

How about looking at it this way:

Accel. times would be another step, but I don't have the data & it is also dependant on gearing...

Accel times alone do not really tell the whole story. Overall , weight to power ratio, weight to tire size contact patch, and weight to brake surface area are key. Lighter cars will outperform heavier cars on a track with all the ratios being equal because they will be easier on tires and brakes.

I am unfamiliar with this tour de france edition. Care to diverge some more information about it? Also, how did they get the weight so low? Fibreglass bodywork?

I'm always ready to diverge information...

The Tour de France, aka Larousse, car was the lightest 911 ever made (until recently maybe). Alcohol was used to power the mechanics... It is discussed in Frere and Ludvigsen.

Take a look at my Comparision Table of Light Wt. models that Thom posted on his web page - rennlight.com -- that summarizes the known wt. savings techniques for all the factory cars, as well as some innovative privately owned cars, such as Grant G's Carbon Copy, Jim Calzia's purple car, Jack's car and a yellow car done by the Gamroth operation.
