How Sprint Cars Work: A Beginners Guide to Sprint Cars
J & J Motorsports News ^ | undated | Al Drake and Craig Smith

Posted on 08/10/2014 3:04:23 PM PDT by jjotto

This is guide for the casual fan that would like to know how a sprint car works and what the various parts are on the car. Entry level education on the terms will help you at the race track when the announcer says "this broke" or a driver says he had a problem with "that" during an interview.

The Chassis

In this case, the chassis is manufactured by J&J Chassis Company. It is called a "downtube chassis" because it has tubes that run from the top of the roll cage down to the front of the car. This provides stiffness to the chassis and limits flex more than a chassis that does not have the tubes (primarily older cars). The chassis is made of chrome-moly steel tubing. The tubes are welded together in jigs that allow the manufacturers to create a consistent line of cars.

The Drive Line

To start, sprint cars don't have a transmission. They are either in gear or out of gear...

I think the jink the rear end took was a result of the rear tire hitting the other driver. My son has pro software for video work and he looked at it, slowed it down as much as possible and then froze it.

Too bad the kid had such a dose of “bad ass” to not just stay close to his car to do his salute.

Stewart was going the same speed as the other cars, remember, no tranny on sprinters(just and in and out box) and going slow doesn’t work.

I drove one for fun at a track in Perris. There are “no brakes”! Direct drive only. No starter, must be pushed by a truck etc to start it. They run on methanol and like another poster said it will jitter your eyeballs out. I believe Stewart made an attempt to swing the rearend away from the dumb walking racer on the track.

Sorry for the death to happen but car vs human and he paid the price. Dumb move in my opinion.

MSM is making this accident into a murder story intentionally.

Bottom line, motor sports will eventually fall as NFL will due to pressure from the Left.

In the mean time motor sports will be pushed to limit their racing vehicles to electric powered with large soft bumpers and speeds not above 10 mph.

Amazingly advanced engine!

I wish a legion of ignorant sports talkers would do ANY background on any aspect of sprint car racing. Their research ended at ‘Stewart’s a hothead’. They watched a video of an event about which they have no clue and pretend to be experts. Even after several days of opportunity to talk to someone who really knows the sport. Amazing laziness.
