<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">If you’re talking about LeMans Classic each race is 1hr long and you are required one stop; however re-fueling is not allowed in the pits so if you don’t have
enough fuel on board to make the full hour you have to go back to the paddock to re-fuel. Depending on your particular groups paddock location it is possible to do this in the 5min pit stop time but definitely not guaranteed.

the crew has fire suits and a fire extinguisher. <o:p></o:p></span></p>

<p>Not much info stat-wise on thr evrnt online.<br>
>From what I can piece together, these vintage races are 2 hours long, they use the 8.48 mile/13.65 k course. 1972 championship lap avg speeds were in the 138 range.<br>
So is it safe to assume that<br>
130 mph is an avg now for people who do care if their car is damaged?<br>
2 hours at 130 = 260 miles<br>
Divided by 6 mpg = 44ish gallons.<br>
Do you make a single refueling stop? Just one?<br>
So 22-23 gallons onboard?<o:p></o:p></p>
<p>23 gallons = 150 lbs.<o:p></o:p></p>
<p>Or 2 fuel stops with a 15 gallon cell?<o:p></o:p></p>
<p>15 gallons = 98 lbs.<o:p></o:p></p>
<p>Is this about right?<o:p></o:p></p>
<p>The size that you need is<br>
About 23 or 15 gallons?<o:p></o:p></p>
<p>1 cubic foot = 7.5 gallons<o:p></o:p></p>
<p>So you need either 2 or 3 cubic feet of of fuel cell capacity.<o:p></o:p></p>
<p>I think between the area in the boot not used by the brake systems and the battery that 2 would be easy to achieve. 3 might require a secondary cell location.<o:p></o:p></p>
