Speed,

 

Just stick your hand out the window going down the freeway @ 60 mph. Quite a lot of pressure builds up, eh? Likewise, downforce comes into play at just about every track where speeds reach 60 mph, or above, to some extent or another. Of course, the slower the speeds the less downforce plays a role. Conversely, the higher the speeds, the more downforce plays a role. And that role is the ability to stick to the track during cornering. The more the downforce being generated, the better the car will stick to the track.

 

At SAS downforce is more important than at THR or CC or HMS, but no matter where you race, you always want as much downforce as you can get. If two cars were exactly equal in all respects except downforce, the car with the more downforce would have an advantage at each of the tracts mentioned above.

 

Hope this helps.

Nick is absolutely right about downforce on a short track. Last fall at the Bigshot, the Romco car I help out got tagged by another driver on the first lap, and it knocked the rear spoiler down. Only losing the spoiler killed the forward bite, and the car was bad loose until the pit stop when we repaired it. That is at Kyle, a 3/8th mile. Imagine how bad it would be at San Antonio.

A body like the one in question would be a tremendous advantage in the hands of a racer who knows how to use the air.

I wish I had a dollar for every square foot of aluminum and lexan we used trying to get downforce over the years.

Just talked to a friend who said it probably won't be available until March in any quantities. He was going to get one until ROMCO and the Southern All Stars outlawed it.

Garvey's Snowball car kinda looked like this body with the nose dropped and the rear quarter panels kicked up a little.

Tom,

 

Several of the bodies I observed at the 2002 Big Shot looked very similar to the picture of the 5-Star "downforce" body posted earlier in this thread -- dropped noses and raised rear quarter panels. I'd say significant aero work takes place in some race teams' shops between the time the body is purchased from a vendor like 5-Star and the time the car hits the track.

Tom,

 

Wasn't the traction control device working properly? LOL

;) Let them rum the dirt bodies,they are a lot cheaper anyway,and if you look at a lot of the new bodies they are a lot like a dirt body of the past anyway except the bodies are more rounded. the five star bodies diagram shows 48 inches fwd. of the spindle anyway and that is what the dirt bodies were anyway,note except for the wedge cars. Take a look at the Main Event late model series up north,they run on asphalt,the web page is on the late model digest site.

At TMS you want to poke a small hole in the air, reduce turbulance and drag to a minimum and keep as much air from going under the car as possible. The nose on the 5 Star "downforce" Monte Carlo would produce too much turbulance (drag) at the place where the nose bends down so radically and too much turbulance (drag) at the rear since the body and rear spoiler stick up into the air so far.

 

However, you always need a certain amount of downforce on a superspeedway car or else it will take off like an airplane since the air has to travel further (and faster) over the top of the car than under the car producing lift much like an aircraft wing. Thus the slope of the nose, the rake of the windscreen and the use of a rear spoiler on SSpedeway cars. Smokey Yunick figured it out and built a shrunken race cars for the long tracks just so his cars wouldn't have to move so much air out of the way.
