anyone with a 255 cup, how long can you run at 10/10ths? i'm wondering how far the 70L of fuel goes.

I'll reply for what it is worth: I averaged between 12 and 15 MPG in a standard 2005 Elise on track. Others have reported having pick up problems for the last quarter of a tank, but I really didn't. I am going to guess that a supercharged, higher HP car will average less.

S240 i average about 10.

I average 7-8 mpg while race like conditions.

The faster I get on track the more gas I use... Use to be around 11mpg, now Im probably closer to 7-8mpg... Generally 2 20 minute sessions will take me just below half a tank.

so, is my math right here, that's 1:30 to 2:00 (hours) of running time? not bad.

...yeah, as long as you don't run out on your way to the fuel station between sessions like i did...

(those back roads from HHR make for a looooong walk)

Seems like at 7-8mpg and 70 liters, plan for 120 miles till empty?

1:30 at 80 mph ave lap speed and 2:00 at 60 mph (kart track) ave lap speed. Less time if you are faster, it is a cup car after all. If the cup car has a tripometer, reset it and pull in after 100 miles/160 km and see how much fuel it takes.
