There's someone here who always claims that the % difference between different drivers is minimal....but I still have my doubts - me who has done maybe 3 runs in his whole life v. he who has 'worn out tyres in one season dragging' has got to be quicker up the strip.
And "
he" has always maintained that its the average of "
many" runs that gives the accurate figures
And why is it that you think its "
my" opinion, its the opinion of some very well respected
physicists and engineers like err David Vizard for instance, he recommends in several of his books using the drag stip as platform for testing engine modifications and even cites some of the maths.
The statistical theory being that the more runs you do the more accurate and representative the figures
As for 3 runs Sean, were they on an accredited 1/4 mile ?? if not then you have done 0 runs.
For
reference (once again, this time please actually read it before posting a reply) I link to
Stealth 316 - Formulas for 1/4 mile ET & mph vs. hp & wgt
In particular the spreadsheet
http://www.stealth316.com/misc/performance_lrt2.xls
This guy has collected 243 1/4 mile times from various cars and plotted their calculated HP on a graph (he uses several poplular methods) read the article then tell me that the drag strip as a method of HP calculation doesnt work
Or if your not happy write to
