As I've said in other posts...I'm new to modified racing. I've been a crew chief for a karting team for about 10 years. The same rules apply when it comes to taking notes and being prepared...

My question for all of you veteran drivers/crew chiefs out there is this:

How do you know how to read the track? And, how did you learn what changes to make when the track changed?

I have a cry for help on a dry-slick track in another post... Any help there would also be appreciated.

Thanks,

M

Let me just say this. In general you want to soften your car up as the track drys out as long as its fairly smooth. Stiffen your settings (IE: springs, shocks, etc.), for tacky tracks. As far as reading the track, monitor the conditions as the night progresses. Do you still need tear-offs? Is mud being kicked onto the walls? Do you see hints of dust as other cars race through the corners? Are black or darker colored areas starting to appear on the surface? Is the wind blowing and what parts of the track remain shaded? These are just a few things to BOL for. You should check track conditions at least 3 to 4 times a night and always before your own race starts. Try to anticipate what's going to happen. Does your track operator water during intermission? Good Luck, Larry.

Alot of times, I will walk the track during intermission, & stick a screw driver into the track in different locations to see just how far the moisture goes down into the track. If I can bury the screw driver, the track has a chance of stayng somewhat tacky. If it only goes in a little, then it's more than likely gonna dry out. Pay attention to the weather. If it's hot & dry or windy, probably gonna turn dry. If it's cool & cloudy, it might stay tacky.Especially if you've had rain recently. Hope this helps alittle.

I have found that a go-kart is harder to set up than a full size car. Mostly because you have to stay free but not loose to be fast. Lack of horse power in a kart to weight ratio makes a tenth of a second really matter. Think of you kart tires as springs (cause they are) and adjust your springs on the race car like you would adjust the tire pressure and washers on the kart. For example, kart is loose in tight off. You would take some cross out either with air pressure or moving a washeror two in the front of the kart depending on how loose it was. Well, same rules apply to your car if it's a little loose in, adjust air pressure, if it's really loose in adjust weight jack bolts. The same rules apply in both. You just have the horsepower in a race car to make up for being alittle off. Good luck.
