Under the NDRS Drag Racing Series sportsman  umbrella no category features more variety than the "Competition eliminator" class, here you find dragsters, altereds, coupes, sedans, front-engine nostalgia dragsters and trucks.

The engine combinations are just as diverse as the vehicles, from turbocharged four-six-eight cylinder engines to normally aspirated hightech engines in a range from around 100 ci up to 800+ cubic inches, also supercharged engines and nitros oxide equipped engines in various sizes are part of the class variety.

There are fiftyfour subclasses in which you can compete, for every subclass you have a formula based on total car weight divided with engine size, the subclass identity is the letter combination on the side of the car (ex CT/A followed by the start number.)

Each subclass runs against an index, initially based on how fast a well built car is supposed to run, the difference between the two cars indexes creates the handicap start, the first car over the finish line is always the winner as long as he/she has not redlit, you can never breakout.

You can hurt your index though, if you run more than ,50 under in eliminations you get a personal index change at the event with as much you drove beyond, example; you go in A/D with 7,60 index and you go 7,05 in the next round you lose ,05 so your index will be 7,55, so it will cost you to instantly in this actual elimination.

Furthermore if you go more than -,60 under you hit your index permanently on monday with as much you drove beyond, example your run was a 6,90 in A/D still with 7,60 index, then on monday and permanently your index will be 7,50.
This is called CIC (Competition Index Control) and is truly like the saying: "If you live by the sword, you die by the sword". The charm with the class is the individual thinking in the combination you have developed and that you can drive against nearly whatever car your competitor bring to the line in a fair way. A VW powered dragster can run against a Top Methanol funny car or a  turbopowered Pro Mod car and the best man wins.. David vs Goliat...

Maybe this sounds complicated but it is really not, print out the "Competition Eliminator index" list and bring a pencil to the stands, read the classification on the side of the car, make your own notes and discover the thrill of the "Comp eliminator" mathematics!!
