I have a 10 gallon fuel cell for my IMSA car and I am starting to wonder if that is large enough. How far will 10 gallons take me at 75% racing speed with a 2.5 L six with 40 IDAs? Before I weld up the framework for holding the cell I need to decide if this is big enough. Any experience and insight would be great. Thanks, John |

my builder has put about 20 914 race cars together
his advice to me for track use: 4cylinder = 10 gallon cell 6cylinder = 15 gallon cell you can always run a cell less than full (to cut weight) and more capacity gives you the ability to do enduro events that said, we go through about 5-6 gallons every 20 minutes with a 2.0/6 on the track. We use a tiny bit more when we visit sea level as we normally run small jets at 5500 ft of elevation. brant |

You should consider 8-10mpg.

I am thinking of doing some road rally type events where you drive 250 miles every day. This would be time/distance type events where you can't push much because the road ahead is unknown except for pace notes. I am thinking I need at least 150 miles of range between refueling. It does not sound like 10 gallons is going to cut it. John |
