Sean is correct. There is some type of counter mounted on the front tire/axle, to measure time/distance. I read about all the Matty Box stuff years ago, I don't remember all of it, how it worked, etc.

To my knowledge, other than Matty, who was protested, refused to tear down, and was tossed, at the 1999 Moroso 5 Day, none of the others were found to be illegal at any time. Not sure if they were ever protested (or found illegal). I apologize if I am incorrect.

*edit* I did find this. http://racingarticles.com/article_racing-11.html

Talking Re: Drag Racing analyzer

Would it raise any eyebrows if you just used one of those bicycle wheel contraptions on the rear of the car, like Motor Trend magazine uses?

If i remeber correctly Matty won 1989 IHRA bracket finals @Bristol,I think he also won race of champions there also driving red 62-64? chevrolet.
I was always told the Matty box would adjust car to dial that may been myth,I was told usaully had NOS to pick up or pull timing to slow? Does anyone know those facts?

How could it actually adjust the car? Or did it signal the driver about where it was in relation to the dial? All that came about while I was sprint car racing and then quit.

From stories I read, the Matty Box was like a cruise control. If the car was ahead of it's on-track point (running quick), the throttle stop would kick on to slow the car down to run it's number. If it was behind it's on track point (running slow), the N20 would engage, pick the car up, and run dead-on it's dial.

With the Matty box, after the first initial run to record data, you do not need to make another time trial. As long as the run is good (no tire spin, gear change malfunctions etc) The box records that data and uses it to determine the following runs ET prediction by counting the amout of times the engine fires compared to the distance it has traveled, thus the reason for the counter. It will tell you, by led, if you are going too slow or too fast. You can use nitrous, throttle stop, etc to control this. You can also use it on a footbrake car without a transbrake with a motion sensor that is available. In my opinion, with todays consistent bracket cars, like dragsters, the box would be less helpful. You still have to hit the tree and is appears many can do this and run the number.
