Examples:
If an unrestricted 360 makes 700 HP and has a BSFC (lbs/hp/hr) measured on the dyno of 1.1 at peak power and runs a 10 minute feature without stops it will consume less than (1.1 * 700 / 60) * 10 min / 6.6 lb/gal = 19.4 gals.
If 410 makes 850 HP and has a BSFC (lbs/hp/hr) measured on the dyno of 1.1 at peak power and runs a 10 minute feature without stops it will consume less than (1.1 * 850 / 60) * 10 min / 6.6 lb/gal = 23.6 gals.
The reason it will consume less than these numbers is because non-wing cars let off the throttle going into the corners. A wing car will be different depending on the track because they don't tend to let off the throttle as much.
Do the math for heat races, etc...
I hope this helps,

360 motor on a half mile, 25 lap feature running green to checkered with 2-3 laps for alignment and 4-abreast... should equal about 21-24 gal. of fuel.

Is it a wing car?
So either it's a 750HP engine running at 1.1 BSFC or a 700HP engine running at 1.2 BSFC.

Ted... I based that on a wing car that ran with us at West Liberty IA. (1/2 mile) last week.
He had a bad heat race and had to run the 12 lap B.
They started 17th in the A main and came throught the field to win.
When we were there a year ago... the track was extremely heavy and rough.
With a few reds and a couple of yellows.. we were concerned about fuel. The top 3 cars finished on fumes.

It depends on how rich or lean you have your pill set at in the fuel system. It also depends on the length of the track and the amount of caution flags. Short 1/4 and 3/8 tracks ( ex. Husets or Cameron ) with 25 laps burn less fuel than a 1/2 mile ( Knoxville or Sedalia ) with 20 laps. This is just my obsevation, I have not compared notes with anyone else.
