Pants Ring 9.05

Posted a replay to alt.binaries.simulators.autos By watching the tach you can see that the tires are periodically spinning up. If someone can tell me why I think sub 9s are possible. -- Don Scurlock Vancouver,B.C.

I have a 6.05 second lap while racing on VROC 5 others were in the room with me.

I'm sure David G. Fisher's neighbour can help you out here... Andre On Thu, 27 Apr 2000 22:52:11 GMT, [email hidden] (Don Scurlock) wrote:

It's all to do with the contact patches of the tires, because (as Casper has just pointed out) the sections of track form V shapes. Low contact patch = low grip = wheels flare up. (I think!) Phil Don Scurlock wrote:

If someone can tell me why I think sub 9s are possible. Ok..I have nothing better to do, so here goes my theory :) If you watch closely from the 'arcade view' you can see that the curvature at the top of the bowl is made up of two sections with an angle to each other. When the car happens to be positioned so that the right hand side tyres are on the top section and the left hand side tyres are on the bottom section then the center of the car will be above the very shallow V made up of these two sections (i.e. the center of the car is above the point where the two sections connect). When the car is at this position the ground clearance is higher than when it is positioned totally on either section. More ground clearance -> more speed before bottoming out -> more revs (maybe). So what you want to do is keep the car above this V-point. The problem is that this point seems to be an unstable point and the car does not want to stay here. If you're very precise and quick with the steering you might be able to keep it at this point for a longer time and maybe then break into 8 second laps. Good luck :) Regards, Casper

After reviewing the replay in light of your comments I'd say that you were spot on. I'm using Race Engineer to max out ride height, springs, shocks and bumpers. You can't do any more to prevent bottoming. On staying over the groove, I wasn't really steering the car, it was doing a slow weave all by itself. I don't think you could stay over it either. I'm going to play with the other cars and see if they have any positive quirks. [email hidden] (Casper Gripenberg) wrote in <2BfO4.1538$[email hidden]>:
