Definition of "index"

[tt6pam]

Can someone explain the "index" term used in dragracing to me


I thought that if you were racing in a class that has an index of say, 9.90 seconds, you aren't supposed to go faster than 9.90 seconds.

Index racing is a bracket race where everyone has the same dial-in and they are started by a pro tree.

So are you not supposed to run faster than the index I'm confused because when I was looking at the eliminations for the Prostar 600SS from Norwalk, it appears that some of the winners ran faster than 9.90, and the person in the other lane didn't redlight, and I'm assuming they weren't disqualified for some other infraction.

600SS is a heads up class- no index- the first bike to the finish line wins. Index classes are:


Super Gas 9.90 index


Super Comp 8.90 index


Top Gas (my favorite index class[img]smileys/smiley2.gif[/img]) 8.20 index

Pam,


It is possible to win and go faster than the index, without the other car/bike redlighting orsimilar rule violation. This is brought about by what is called a "double break out". Example: say the"index" is 9.90, if one bike runs 9.86 and the other runs a 9.88, both bikes have run quicker than the index, but rather than disqualifying both bikes, the bike that breaks out by the least is declared the winner. In my example, the 9.88broke out by the least so it is the winner.

Yes, I'm aware of that.

But I believe in the Prostar rulebook (pg. 53) they list the 600SS class as a 9.90 index class. That's where the confusion occurred.Edited by: tt6pam

Sounds like the index class is just E/T with the same dial

Must be a mis print or they never thought the 600's would go that fast...

Heads up is just that, no limit on the top! First to the stripe wins.
(as long as you don't leave early or cross the center line.)
