As far as I know the new 33 gallon fuel cell or tank rule is suppose to go into effect this year 2011 , as well as no fuel stops and another new rule .

Not sure about ALLSTARS , but I beleive what ever was mentioned would go into affect can't see them using a different size then the WoO ?

weight rule upped.

Well with a bigger tank the car would be heavier.

he's correct and the king of the west series is following suit as well with the weight rule too. I heard this at the Trophy Cup from a very reliable source. It's definitely true though.

Trophy Cup......Best race of the year hands down!

"Well with a bigger tank the car would be heavier."

that is not really true. you could off set the added weight of a larger tank by reducing weight some place else. the weight rule is a minimum weight rule, so if the car weighs a little more, it still passes.

i don't know what will happen with the weight rule and don't care, but the little bit that the bigger tank might add to the car should have no effect on determining it.

if they want to raise the weight rule they could say no titanium or carbon fiber, and that would also cut cost.

to indy and beyond!!

The logical reason would be safety and cost. If you add the weight of a bigger tank, and presumeably more fuel to a car, but leave the weight minimum the same, most teams would then lighten the rest of the car. That would cost more money.

Maybe if the minimum weight was raised, some teams would put in driveshaft hoops, real nerf bars, other safety equipment, and protect the area around the driver's feet with something thicker than the aluminum the thicknes of a beer can.

Tank not mandated, but lap count is base off of 33 gals, 1400lbs weight

As for no fuel stops that is impossible, what just run until everyone is out of fuel?

A 33 gal tank is only letting you run maybe 8-10 laps more and on some tracks it could be only 5 more laps. Fuel uasage depends on alot of different things. ( track size, speeds, air, time of year)

if the teams lighten the cars thy are not going too pass tech after the race when the fuel is gone remember the car has to weigh a minimum i agree with raising the minimum but a bigger tank has nothing to do with it it will make the car heavier at the start of the race but not at the end as the fuel will be gone

I see what you're saying, but...the bigger tank, bigger tail and perhaps bigger tail nerf bars would add some weight. Without raising the weight minimum, the teams would be shaving some weight somewhere else.

Bigger tail would be nice. I think Silver Crown cars, with that big long tank behind the driver are the best looking race cars in the world. I've always wanted to find/buy a print for framing of a nice paint job Silver Crown car, preferably with a top USAC driver kneeling beside it. One was part of the Knoxville Hall of Fame auction a few years ago, can't remember what the guy paid for it, but the frame had a light built into it. Pretty damned neat it was for sure. Out of my price range it was for sure.

Detroit, Seattle, Chicago, Minnepolis, etc. We saw it. 
Burning hundreds of buildings, a thousand assaults and 
dozens of murders. Getting worser and worser.

Question...............

Why couldn't they change to the high octane racing gas like the late models and DIRT big blocks run. They have no problems running 100 laps plus caution laps with 30 gallon fuel cells. And that's with engines pumping out anywhere from 800 to 1000+ hp.

Would it be that hard and expensive to switch??

I don't know that I agree with you.

More work=more money. If lightening a car means using more titinium in place of steel that's more money.

Several drivers were injured this year in the feet an ankles. Terry McCarl broke his leg when "a rock, or something" came through the ultra-thin aluminum side panel near his feet.

More substantial side nerf bars should lesson the chance of hopping a wheel or getting a wheel into the driver's area. It's just a degree of difference. If side nerf bars did nothing, why would anyone have them?

it only makes sense here. at roughly seven pounds per gallon that would raise the weight of the car approxomately 210 lbs. don't honestly think they can shed that much weight from the car. jmo

Ascot was the greatest of all time..

West Capital wasn't half bad either..

Life is good...

33 gallons - 28 gallons = 5 gallons(the difference in the small tank from the big tank)

5 gallon X 7 lbs/gallon = 35 lbs....

Where do you get 210 lbs???

Better check your cipherin', NW!

Chuck.....

Kind of didn't think that through

5 x7=?

plus that weight is only at the beginning of the race. the car is weighed AFTER the race, when fuel will be burned. IF guys are filling their 28 gal tanks now and are putting maybe 5 gal in on a fuel stop and ending up with a couple of gal at the most at the end of the race, what is the difference of filling up the 33 gal tank and not stopping for fuel? you still have put 33 gal in the car, and you still would have the same fuel left at the end of the race. the only difference in weight would be the small added weight of the bladder and shell and possibly the little bit of rear nerf. some teams are adding weight to their cars as it is, they will just add less to make up for the larger tank. i have no problem with raising the weight rule. make a no titanium and carbon fiber rule and the weight goes up on its own.
