How Much Race Gas?

[motorhead]

What is a good (in terms of litres or gallons) purchase for a day of racing at the track? I might see as many as 7 passes.

I fully intend to drain the tank into a 25L jerry can after arrival... and I have a 2nd 25L jerry can for the C16.

Any thoughts?

I have gone to the track running 5 gallons of race gas only, most would probably suggest having more in the tank just to make sure you dont cavitate, The last time i went i had 5 gallons to start with, and ended up saving about 3 gallons of it for next time.

I agree with having 1/2 tank to start with and then adding more as the day of racing goes on.
You don't want to have the pump lose suction and starve the engine for fuel. That would be very BAD and COSTLY $$$$$

I would buy 10 gallons and pour it all in. Drain it at the end of the day and you will likely still have6 or 7 gallons left. Then you can use all 7 gallons next time.

I think 5 gallons is about the minimum, but after 4 or 5 runs you could be risking cavitating on launch.
