0-60 Time

In the absence of a rolling road it is nice to see if the performance of the car is dwindling in horses in any way.

There is an excellent on line 0-60 mph calculator http://www.060calculator.com/

For the Megabusa this gave 3.9s for 621.5kg and 176.4bhp. The weight was taken from the recent corner weight measurement and the bhp was taken at Sitech racing last year http://westfieldbusa.blogspot.co.uk/2014/06/dynamometer-test.html

I set up a track on Race Chrono, using a safe bit of road where the terminal speed was less important and 60mph was obtainable in relative safety. You can see that the example gave a result of 3.7s which is about 0.2s optimistic (or the Sitech results are pessimistic). However if you take into account that the test track was up a gradient and the starting speed is not 0 then the level of correlation is not bad.

I have measured my wife's Mondaeo, Sylva J15 and a Westfield Zetec and all gave results that were within about 0.5s of prediction.
