[DeTomaso] Front trunk fuel cell?

[michael@michaelshortt.com]

Thanks.

So divide everything I said by 2.

130 mph avg for one hour = 130 miles.
Divided by 6 = Call it 22 gallons.

Or 3.4 cubic feet of gas

12 gallons up front and 10 in the stock location in a smaller cell.

Assuming you have 180s installed.

What have others done in the past?

Michael

Michael,



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.



Other Euro events might have different rules? Most of the Vintage endures
in the US allow re-fueling on pit lane as long as the driver is out of the
car and the crew has fire suits and a fire extinguisher.

Not much info stat-wise on thr evrnt online.
>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.
So is it safe to assume that
130 mph is an avg now for people who do care if their car is damaged?
2 hours at 130 = 260 miles
Divided by 6 mpg = 44ish gallons.
Do you make a single refueling stop? Just one?
So 22-23 gallons onboard?

23 gallons = 150 lbs.

Or 2 fuel stops with a 15 gallon cell?

15 gallons = 98 lbs.

Is this about right?

The size that you need is
About 23 or 15 gallons?

1 cubic foot = 7.5 gallons

So you need either 2 or 3 cubic feet of of fuel cell capacity.

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.
