Thanks,

I was interested to see if there was going to be any replys to this because i havent found one either and really on dirt there is not any magic insight to the cars handling thought the tire temps like there is on asphalt, due to the amount of slippage that occurs. I basically check tire temps to be sure that they are in the operating range for the tire and as a secondary tool for making decisions on chassis changes. I think its more important to take into account driver feel and your own observations as far as handling goes and usually the temps will work themselves out.

As far as good general chassis books i tend to shy away from refering the steve smith books, much of the information is second hand and pretty limited in explanations. Alot of the information is pretty dated also, but since they are the only real books that have been written on dirt cars specifically there arent alot of options. For a true understanding of race cars in general i reccomend "Race Car Vehical Dynamics", it is available from SAE. Its definately not light reading and isn't nuts and bolts information, but if your really interested in what makes a race car work its is the best thing going.

The reason I was wondering is that besides learning how the car works, I'm also working at helping the driver learn how to describe how the car feels. Seems this is going to be an ongoing thing... crew vs. driver.

When I'm seeing a change in the way the tire temp patterns are emerging, it <b>must</b> mean there was something different in the way the car felt too... or at least there should be....

I didn't bring my notebook with me today, otherwise I'd give you some examples.

Thanks for the recommendation on the SAE book. I'll have to look into it. Regarding the Smith books... we've never really liked those as the mod books all start out "in this underpowered class" (referring to IMCA)... and we all know that's not the case in UMP.

Thanks,
