9 or 10 gallons/minute. That's about what a 2 liter Solex gets, right :)
Anyways, I try to not drive top down unless it gets above -50. Guess I'm
just a California boy.

No MTBE, but JP4 has various additives to deter wax formation and fuel
freezing
below -60 deg F. Nice rush from the 10,000 lbs static thrust, but something
to
consider is that fuel flow is on the order of 9-10 gallons/minute (56-58
lbs/minute) at sea level. How many you need?
