Experiment

A few years back Patrick Wood persuaded the Bugatti Owner's Club to allow him to do some experiments during a Saturday Practice day at one of the hillclimb rounds at Prescott.

Firstly the tyre temperatures were taken in the Paddock.
Next Patrick drove down to the track and got ready for his run. The tyre temperature was again taken.
Patrick then did a series of 'burn-outs' and the tyre temperatures were again recorded.
Patrick and the MP58 were then pulled back down the track and he went through the tyre warming exercise, was lined up and when the green light came on rather than accelerate away the tyre temperatures were again taken.
This was repeated for all of Patrick's practice runs.

The findings of all this were that no matter how many tyre 'burn-outs' you did the tyre temperature would fall away dramatically during the wait for the green light.

After the exercise Patrick tended to do fewer 'burn-outs' however they were more extended. He also liked to get away as soon as the green light came on to maximise the temperature retention in the tyres.

In the final analysis it is what the individual driver believes is the best method that counts, after all it is the psychological advantage that matters.
