What were ambient temperatures and humidity?
3 or 4 shoe clutch? What springs?
Light medium or heavy flywheel?
What tires and rims and how heavy were they?
What fuel were you testing with?
This is all relevant to me as a dealer because as a racer a possible 10 minute engine is allot more valuable than an 8 minute engine. Especially here in AZ where most mains are 20 minutes. I would like to have a civil conversation about whether or not it's possible for this engine in stock form to go 10 minutes in AZ with the proper set-up
I love it when racers believe their engine will go 10+ minutes in the main and they run out of gas. Happens at just about every big race I attend and they're about to kill their pit man. You change 2 or 3 variables above and run time goes down significantly. I would tell folks this engine will do 10 minutes...if you can drive it smoothly. Anything else is just a false hope as many racers do not set up their vehicle and driving style for fuel economy.
