Re:

Open-wheeled/exposed-wheel cars may be at a disadvantage on a crowded, wide track. As they say, "rubbin' is racin'" and other cars rubbin' against those exposed rolling wheels could be a momentum killer.

I've been reviewing quite a bit of video of open track racing(mostly from gravitywerx & DCR) this week to to help get a better understanding of car behavior. I think this video from DCR's "Northshore Hills Road Coarse" shows a clear examples of what I mentioned above.

http://youtu.be/EhwX-9oTj0I

The cars appear to be evenly matched with speed, but in both races the open-wheeled Thunderstreak gets 'pinched-out' by the Ferrari 312P(solid body). If you look closely while the cars are in close-quarters during the 'passing attempts', it appears that the brief force of the heavy Ferrari body against the exposed, rolling wheels of the Thunderstreak was enough to slow them down. In the 1st race you can see how the Ferrari maintains more of its momentum after contact, while the Thunderstreak almost seems to pause before regaining speed. The Thunderstreak is not so lucky during the late pass attempt in the 2nd race.

Just an observation...

hi guys,

I am from aruba...in the caribbean.....when you have a chance please take a look at the track we race!

here is the link ! http://www.facebook.com/#!/profile.php? ... 2244971952

that is the track....you guys can email me for advice or any suggestion or just let me know what you think.

Regards !!

We have diffrent categories....stock (untouched) and cars filled with lead in different categories ,different weigths.....sometimes goes up to 400+ grams....

HELLO G,
THE CHICK HAS LEFT THE NEST... PLEASE CHECK, AS I PUT SOME DECAL / STICKERS INSIDE THE BLISTER... THIS CAR HAS NEVER SEEN A TRACK SO I DON'T KNOW IF IT IS FAST, BUT IT IS HEAVY.... 112.1 GRAMS ENJOY SMITTY

Thanx, Smitty...you're the drag races because of poor tracking. I can imagine that the problem becomes even more amplified on a wide track.

First of all, I'd like to take some time to thank all of the kind folks here for their patience and willingness to share knowledge with a racing nooB, such as myself. Even after spending many years just fair price...please PM me.

SORRY G,
MY BROTHER AND I LEFT THE TRACK IN THE ATTIC WHEN MY FOLKS SOLD THE HOUSE [ 1979 ]... YIPPIE EYE OWE KIYEA FOR THE KIDS OF THE NEW OWNERS... BUT I WILL KEEP A LOOK OUT FOR SOME... 2 YRS AGO T.J. MAX HAD A FEW SETS FOR $12.00 GONE WHEN I GOT THERE...

The width of an open-lane raceway does not limit the amount of cars that can race at one time. It is not a drag race. A fast car will overtake a slower one eventually either by having a long enough track or running multiple passes (Gravitywerx). I've run 25 cars at a time with no jammup and recently constructed a 50-car gate. And an open-laned track is always "fair" because all of the cars are exposed to the good and bad sections of the track. If a contestant's car frequently has a problem with a certain section, that contestant needs to switch cars. And the last thing you need to be concerned about is being "symmetrical". As long as the straights are long enough to regain momentum the turns can be anyway you like them. The more assymmetrical the better.

Hello George...yes, I'm familiar with the multi-car staging that you use on your track. And I 'contact' is involved. I think that incidental contact is less likely to "go wrong" if all of the cars are within a few grams of one other. Also, racing in weight classes should encourage competitors to concentrate on other intangibles, like rolling resistance and vehicle tracking.

if you start a light weight, altered car , drag racing league ( no crashing) i am in, it is most challenging to"shave" a car to make weight... we found weight classes gave us more winners, but not too many as it's [ hard to get at least 4 or 8 racers in each class]

uncontrollable factors that prohibit it from being a legitimate form of competition. I believe that a smooth, properly designed coarse could significantly reduce many of those negative factors and allow for some speculative predictability that competitors can 'game plan' around. That's also the main reason that I'd prefer a symmetrical design.

All of those big words sure seem to take the
fun out of racing.

When you are stating that you prefer a
symmetrical design, are you talking about
just having straight lanes? Also, does that
mean that one car per lane or are you open
to, Open Track racing?

My open track design will use single 'entry lanes' at the beginning of the coarse which will allow each car to accumulate some speed before hitting the lane-less track. DCR does this as well on their Northshore Hills coarse. "Symmetrical" refers to the coarse shape...as in 1 left hand banked curve and 1 right hand banked curve with strait sections in between. This can be accomplished with either a 'spiralling figure-8' or a 'descending S' design. I realize that symmetry isn't a fair competition.
