all chase races will now include....

NASCAR should just make a rule that says:

With 30 laps to go, there will be a Competition Caution so that everyone can fill their tanks and change their tires - and it will be mandatory that all cars change 4 tires during this caution period.

That would end all of the whining about how crappy "fuel mileage races" are!

That still might not prevent the "phantom debris caution" later in the race, however.

BTW, I know that this is a bullsh!t idea... ;)
 
This fuel mileage crap will go away with the FI next year because ther will be no more tuning on carbs.

REALLY? I'm not so sure about that. Drivers and crew chiefs will still try to stretch their fuel mileage to the Nth degree to gain any advantage in a very competitive arena.

There's alot more to fuel mileage than how the carbs jetted. Here's a few fuel mileage things that fuel inj wont change.

One of the biggest thing is how much attention the crew pays to the fuel pickup in the tank you have to be able to get every drop. Beleive it or not this pickups location has to vary from track to track to accomplish that.
Another thing is the fuel system vent and fill pipes paying attention there not only lets the fuel get in faster but you don't dump out a gallon leaving the pits.
Alot of people say that the driver can make a huge difference, butt I find it odd that some of the guys known for getting better mileage where the ones that ran out today???

Did you see Stewart using the Keselowski method? Too bad he didn't know that one last year.

Interesting. I thought the design of the fuel cells were mandated by the governing body.

I stick to my original comment about FI.

FI could make it even harder to get the last gallon out of the tank. Those systems are a bit more sensative to a drop in fuel pressure.

For the life of me, I can't figure out why NASCAR went to a mechanical pump instead of a fuel system kill circuit tied to the ignition.

Man that was funny stuff! I remember even in the post race interview they did with him he was between two haulers and it looked like he was in a dark alley all shady and stuff! lol

No I sure did'nt because I was at work and my IT people.............well lets just say I,m not happy with them.

The only specifications NASCAR mandates on fuel cells are safety related, bladder and shell material and thickness, check valves, fill hose and vent hose diameter and lenght, mounting materials Plus of course capacity. Pick up design and location is wide open.
Fuel injection may even the feild slightly on fuel milage, definately makes more power and decreases engine failures, we'll have to see ;)
 
I hate fuel milage races to, but I do believe the best car did win the race.
 
I'm kind of curious to see how the fuel injection switchover affects the sport.

One thing that happens with fuel injection is that the fuel pump will burn right up if it is starved for fuel. Gasoline is what lubricates and cools an in-tank electric fuel pump. I wonder if trying to stretch out their fuel too much will cause this to happen on these cars.
 
Saw this somewhere.....

Top 10 reasons for not winning a fuel-mileage race:

10. Team downsized fuel cell to make room in trunk for extra luggage.

9. Too busy rubber-necking past all the crashes to maintain a steady, consistent speed.

8. That faulty batch of fuel gauges from Crazy Joe’s Automotive Warehouse & Beef Jerky Emporium.

7. To make his job easier, gas runner only filling cans halfway.

6. Gas mileage never an issue when we start and park.

5. Gas man still having trouble with those new child-proof fuel cans.

4. Real men don’t stop for gas, or ask for directions.

3. Too busy “checking your volts” to notice fuel gauge was on empty.

2. Corn cobs from new ethanol blend keep clogging up the fuel lines.

1. Crew chief’s suggestion for saving fuel: “Drive faster to get there before you run out.”

To kinda answer your question NASCAR's new fuel injection system use's a cable driven in tank Mechanical fuel pump similar to whats being currently used.
It's true if you drive a modern fuel injected car don't make a habit of running it low on fuel it over heats the pump and shortens the life of the pump, also if it has a replaceble fuel filter ( Surprise many new vehicles have no external fuel filter ) change it on a regular basis.

As long as the fuel cells outlast the tires there will always be fuel mileage races. Simple as that.

I'm not sure it's that simple. On the last stop, most teams didn't take tire. Just a top off. Word is that Stewart changed left side tires just once in the entire race.

You're kinda restating my point. They didn't have to take on tires because the tires are outlasting the fuel runs. Turn that around and nobody would run out of fuel.

Now I'm confused. The tires outlasted the fuel cells, not the other way around, and we got a fuel mileage race. If the fuel cell were bigger, the race would have been decided by tires.
 
I am not sure if I'm having a hard time explaining myself or if you're having a hard time understanding me. The tires need to wear out before the fuel runs out so that they have to come in to pit for new rubber. If that happens they will top off the tank. We will never have a fuel mileage race to worry about. The problem is that the tires outlast the fuel cell.
 
Gotcha! Been wondering about that for years now, I was in Guam years back and forgot to check.

Those might not get the job done is a special circumstance. Im betting an engineer that works for NASCAR played some doomsday 0.000001% chance of a car getting driven through a fence by some alien force and the crowd getting lit up. The "Green" Fuel probably has some awesome explosive characteristics that we don't know about. Like how back in the days of European racing, they used Magnesium parts instead of other metals, because of its superior light weight. Until one day a guy with a magnesium car careened into the crowd while his car lit on fire and 90 people burned to a crisp. You can't put magnesium out with water, it just burns hotter.

Then the NASCAR engineer sold this loaded dog **** to some executive who wants to be the "safe" guy. So until you meet this guy to tell him what you think, chalk it up the engineer that has nothing better to do with his life.
