fuel cell location
i am working on an rx8 for a 24 hours of lemons car, for those who have raced these, looking for a recommendation on fuel cell location. i do have the option of using the oem tank, but would like to increase the fuel capacity. will mounting a fuel cell behind the rear axle in the spare tire area be bad for handling? i hate to put all of that weight back there, what with the weight of the fuel, cell, and structure to make it safe. i do have the option of going in the cockpit just above where the factory tank would be, but it will be higher up. which option will have the least negative affect on handling?

Since nobody else responded to your other post or this one yet, I’ll take a crack at it:
Not sure it really matters given it’s a LeMons race and the $500 spending limitation, but the RR passenger area is probably best wrt cornering weight since it’d be offsetting the driver weight (or reversed if it’s RHD). Cutting the chassis sheet metal and level/blank it off where the OE seat & fuel tank was to position it there as far back as possible toward the RR corner, that would probably be best assuming the rules permit it and the capacity/shape of the fuel tank fits. https://www.rx8club.com/rx-8s-sale-w.../#&gid=1&pid=3 |
i was a bit surprised there want more of a response, thanks for the reply. i will measure up and see what can be done to go in the rr corner.

or as close as you can per the pics in the thread link, which was just on the RR floor-board as far back as possible.

@jatmon What did you end up with? I'm in the same boat, debating if I want to put it in the passenger side and enclose or place in the rear but have to reroute exhaust (assuming but haven't measured). That would at least allow me to have a passenger seat on track days.
If you ever see this let me know what size, placement, if you kept it single or added a return line, and issues you had, I'm looking at the 24G ATL's. |
i am still using the factory tank. i tried to get lemons tech to allow me to run the stock tank but relocate the filler into the trunk. they said no way. my reall issue is with the location of the stock filler directly above the tire, spilled fuel goes on the tire and hot brakes. yeah some extra capacity would be nice, but i would rather have a better handling car than an extra couple of gallons. fwiw, i do have a tank and pump set from a 2010, hydra mat on the right side pickup, and i have been getting most of the fuel out of the right side of the tank. i just hate the filling situation
