Fuel Cell Update; 17 gallons in 2007: Drivers say that they don't need the smaller, 14-gallon fuel cell for the races later this month at Lowe's Motor Speedway. NASCAR mandated the smaller fuel cell instead of the regular 22-gallon cell because of concerns about tires on the new surface. A smaller fuel cell will lead to more pit stops and more chances to change tires. This week's test showed the tires are durable enough that they should last what would be a regular fuel run with the larger fuel cell. John Darby, Nextel Cup series director, said more information is needed before deciding to change back to the larger fuel cell. "Until you go through that 600 miles, you don't know what's going to happen," Darby said. Darby said that next year, the fuel cells will be 17 gallons.(Roanoke Times)(5-6-2006)
 
What I don't get is, they already tried (and still use) the smaller fuel cells at the plate tracks in an effort to break up the pack.
Has anyone noticed a more spread out field with the smaller fuel cells??? I sure haven't noticed any difference. As I recall, the wrecks in the Talladega race involved many cars. One of the wrecks was caused by 5 wide racing into the turns.
Is NASCAR not aware that this has no affect on the pack?
The only thing this will do at a non-plate track is make for more pit activity. The teams with consistently better pit stops will make up lots of on-track time in the pits.
So the best guy with the best car may not be the one in Victory Lane. It will probably be the guy with the more consistent pit crew.
I think they should quit trying to change things.

Dream on.
 
NASCAR Sticks With Small Fuel Tank At Lowe's
After a successful two-day test at Lowe's Motor Speedway this week, many drivers lobbied NASCAR to reverse its decision to use smaller fuel tanks during the two weeks of racing there later this month. NASCAR isn't budging.

The 14-gallon tanks will remain in place for both the Nextel All-Star Challenge and the Coca-Cola 600, Cup director John Darby said Friday. Cars generally use a 22-gallon tank, but NASCAR mandated that smaller ones be used at the repaved North Carolina facility as a precautionary measure. After 47 drivers spent two days testing a new tire on the new surface, many thought the smaller cells weren't needed.

"Yes, teams were pleased with the test, but we firmly believe we have to go through an entire event weekend to really see how everything is going to hold up," Darby said. "Is the small cell absolutely necessary to race there? Probably not. But we're going to sit tight, because to go back and unwind what we've already decided would not be fair."

A smaller fuel tank means cars will have to pit more often for gas, preventing long runs that would put stress on the tires. The tires did not hold up well at Lowe's last year, and there were 37 cautions during its two premier events. NASCAR mandated the smaller cells after Jimmie Johnson wrecked during a Goodyear tire test there last month. But the tire company was able to develop a harder compound it is confident will hold on long runs.

Darby said NASCAR will wait until after the 600 to pass its judgment. "It's possible we can make a fuel cell change between May and October (Lowe's fall race)," he said. "But we're not going to risk a repeat of last October before we know for sure how things stand."(Sporting News)
 
Smaller tank almost makes the car lighter, so they have to add weight, so it really dont help anything with the tires, because the more you add, the more tire were you will have.

And, since there is less fuel there will be less weight drop off as you go into a run so the tires will have more weight longer. (Does that make sense?)
 
The weight is going to almost be a non issue with the harder compound tires, Nascar just wants to cover their asses so that there is no way there would be a tire issue...can't say that i blame them after last falls' race !!
 
6.2 pounds per gallon equates to 31 pounds.
I don't think that is as much of an issue as causing shorter green flag runs.
