GPL: Oval setups?

I have just gotten an interest in some GPL oval racing. Anyone have some good oval setups? Everything I make either bottoms, overheats the tires, or doesn't turn...send them to [email hidden] or post a URL here if you have some. Jesse Black

A good tip for oval racing in gpl is to play with the camber at long tracks. Put the left side camber near max positive and right side near max negative. But the steering will pull to the left,ala N4. ;) With the camber at the extremes you lower the rolling resistance with less tire on the ground so you have higher top speeds, plus the car pulls itself through the corners. Just don't use too much camber on smaller tracks or you'll lose too much grip. Goodluck, Jesse. -- Solo1 C-Modified (CASC-OR/BARC) http://www.barc-oc.com http://www.casc.on.ca

There are some at bhmotorsports.com and more at Schubis. In article <[email hidden]>, Alan Orton <[email hidden]> wrote: > Wosco wrote: > > > > I have just gotten an interest in some GPL oval racing.

imho, Stiffen the lot to the max, (esp in bristol) give it a bit of toe in too, run a few test laps then adjust the camber angles individually, works for me <[email hidden]> wrote in message news:953a69$a8p$[email hidden]...

Bad idea, Alan, You should use TPs, not cambers, to reduce the rolling resistance. Once you get the camber optimized (the normal way--use GRE to equalize the temps across each tread), raise the TP so that the center temp is 1-2 deg. higher on the R side and 2-3 deg. higher on the L side. You want plenty of camber thrust on the ovals (higher G loadings), so if you're going to err, the L side of each reading should be higher by a deg. or so than the R side (assuming you're racing c'clockwise, i.e., aren't testing the banking @ Monza). The diff should also be completely open (85/85/1) to minimize rolling resistance and kill the push. You'll also want to run increased ride heights and springs stiff enough to keep you off the bumpers (.5 in.) The shocks should be stiffer on the L than the R. Use the bars to move the roll couple aft so you don't o'heat the RF (you'll probably wind up with a stiffer bar at the back). Take two Goody's and call me in the morning. --Steve Smith Alan Orton <[email hidden]> wrote in message news:[email hidden]... > Wosco wrote: > > > > I have just gotten an interest in some GPL oval racing.

Sorry Stephen, i disagree with you here.. Alan is dead correct for Oval racing in GPL. The high speed ovals in GPL, do not require the car to generate maximum lateral traction, as the centrifugal downforce from the banking will generate enough lateral traction on the high speed ovals in a GPL car. Running too high a tire pressures on the Ovals in a GPL car is fine, for novice length races, providing you don't push too hard, but for anything over a novice length race, your tires won't make the distance if your being pressured from behind. In F3/FG & F2/FD, if you don't set up a high speed oval car using high levels of off-set camber, you will not even be close to competitive with any one that knows how to set up an oval car in GPL. F1 in GPL isn't quite as critical as the other classes, but it still makes a huge difference to the rolling drag factor by off-setting cambers.

Okay, Ron, you're faster than I am.... --Steve Ron Ayton <[email hidden]> wrote in message news:01c08a39$81693aa0$e94236cb@ronayton...
