Never been to the strip, but want to know what times my car can run. Is it common for everyone to change tires to make their runs?

 

Tons of people go to the track on stock tires.
But with your power traction will be a real challange. On the launch or down track. Be very careful.

 

I am learning on the streets how the car reacts off the line around town. This has taken some time. So obviously new tires on a different surface (somewhat prepped) would take even more time, so I figured I'd give the stocks a try first. Thanks

 

Just a word of caution. Street tires act completely different on a track than they do on the street.
Have fun and let us know the results.

 

well as everyone stated , its much different at the track and power such as yours will be hard to hok up. I run street tires and it really sucks cause I get a good mph which shows usable power of your engine but horrible 60ft times usually at 2.4, I don't go much so a better driver could get lower driving my car I'm sure, but it will still be slower without the tires. ET tells you how much power you have used. It just sucks runing with slow cars when you can run with the faster class. From what I've been told, is that street tires don't need big burnouts only a quick small one just past the waterbox to heat them up and get rid of the rocks and other debre on the tire, using the waterbox might trap water in the treads reducing your traction. I've read in car magazines that with street tires to leave the correct psi, because lowering it will bow the tires out, the article I read had pictures of burnouts that seemed to prove what they are saying. I've heard board members say to lower the psi, I just leave it at the reccomended setting. You'll have to ease into the gas pedal off the line, I usually start at about half gas and increase as I get traction, so by the end of 1st on at full throttle. I can't say exactly how much to gas to use, its something different for every car as everyone as different poer levels. I think for most its real hard not to just floor it off the bat. Also note that I get ok traction on the street just practicing, but as soon as I hit the track, its like being on ice literally. The car revs so fast from slipping its like your reving the engine in nuetral, and if you do this after you get traction you can bog the car down as it may drop down in rpm. Regaurdless if you go fast or not, its still very very fun, just be careful, ya don't want to slam into the other driver

 

Thanks for the reply. This is the first time I have heard to keep the psi "stock". I have heard to bypass the waterbox so that seems to be a constant. I just talked to a friend of mine tonight that regulated racing is done for the year here (MN) so I guess I will practice on the streets until the weather tells me to put her away for the year.

 

When racing a regular car on street tires I rarely leave them at street pressure. When a car launches hard it tries to transfer weight from the front to back, even on a front wheel drive vehicle. The added weight to the rear compresses the tires more than during regular street driving so adjusting tire pressure usually helps with traction.

I have found that 20-24 pounds is usually about right on a street tired f-body, and 17-20 pounds on most front wheel drive vehicles.

The goal is to have a flat footprint. Too much air and the edges of the tire don't have enough contact. Too little air and the tire "cups" with the center lifting off the pavement.

A front wheel drive vehicle can get away with less air because the front tires have less pressure on them so that is why you can usually have less air in a front wheel drive vehicle.
