[DeTomaso] Front trunk fuel cell?

[Ken Green]

Dick,
 
    For a mid engine race car with dry sump, does it then make more sense to put the oil tank in front?  I asked the guys at Barnes pumps about that once, they the said the pump would have no problem moving the oil.  That also allow an oil to air heat exchanger.
 
Ken

Sean points out the issue with a front mounted fuel cell in the Pantera - the handling changes as the fuel is used requiring the driver to accommodate for the weight shift on the front suspension with the resultant changes in steering sensitivity, as well as the balance of the car overall.  While there are always trade offs, to minimize changes in the weight distribution and handling characteristics during the race, it is better to have the fuel tank as close as possible to the front to back center of gravity. 

In talking with a member of the Level 5 Motorsports race team, he reiterated what I believe most folks know, that you want to minimize changes in the car dynamics during the race, with steering sensitivity one of the prime variables one would like to have as consistent as possible during a race. 

In working with a friend (a very skilled amateur driver who raced his Westfield Megabusa for several years, winning his class two years in a row) who is building a Lotus Europa race car (mid engine as is the Pantera), he was initially going to place a 10 gallon fuel cell in the front of the car because it was going to be easier (and cheaper) than to fit two 5 gallon saddle bag fuel cells mid ship.  After input from several folks, he opted for the more expensive mid ship configuration for the reasons mentioned above.  He also realized that the fuel tank installed in the more protected mid ship configuration was less prone to failure in the event of an accident.

I'm wondering if the lore of the Miura, also a front tank setup, is true: as gasoline ran low the steering would get light.  So the car handled differently when the fuel was full than when it was low.  I think it's possible that at higher speed the steering got light as well so there might be some confirmation bias.
