Comp has several different classes that have designated e.t. indexes based off of performance of cars at different lbs. per c.i. and motor combinations. The car with the quicker index spots the car with the slower index, and first to the stripe wins. If they run too far under the index they are hit with a quicker index next time, but has no bearing on win or lose by going too fast. Always, first to the stripe wins. Also, no matter what, an A\A will never be spotted by an E\A. Hope this helps, some one else that actually runs the class can chime in and explain it better.

Quite simply, comp classes are based on weight to cubic inch. No horsepower factors. Index based handicaps with no breakout. First car to the finish line wins.

I love comp racing. I only wish I had the money to do it.

Maybe someone can answer this for me. I understand that in Comp everything is based on LBS per Cubic Inch.

So with that said, someone can run any combination right? Any car and any motor combination?

For example:
Dragster has a 400 SBC and weighs 1700 LBS. So that is 4.25 Lbs/Cu In. So if I was to run comp with it, it would be in a dragster class were 4.25 fits? Correct?
Same would go with a roadster or door car?
Granted I know my stuff isnt fast enough just wanting to make sure I understand it all correctly??

Thanks

Close but you are looking at it backwards. When I ran comp, NHRA allowed 170 lbs for the driver, not sure what it is now, maybe the same.

The car in my avatar ran a number of different classes depending on motor and weight. I normally ran B/A or C/A with a 402 or a 347.
The minimum weight for those classes was 2100 lbs. B/A is a 5.4 lb/cu in class so the minimum weight for me in B/A was 402 x 5.4 = 2171 plus 170 or 2,341 lbs.

C/A is a 6 lbs/cu in class so 347 x 6 = 2,082 plus 170 or 2,252 lbs. I also ran G/A which had a minimum class weight of 2750 lbs. It is an 8 pound class so I ran a 323. 323 x 8 = 2584 plus 170 lbs = 2,754 lbs.

There are also different restrictions in the "econo" classes and "super" classes like 1 carb and auto transmissions. These examples will give you a start but you'll need to reference the latest rule book for all of the details.

I always liked to run a class with a full bodied car. I just changed motors and weight to fit the different classes depending on which one I thought had the best index. You might want to also look at www.insidecompracing.com for more info.

get yourself a nhra rulebook, it has all of the classes and weight breaks in there. Some of the class rules are like super stock in that there are limits on carb size and transmission type.

There are no class winners, so you only race for comp win.

You can set records at lodrs events. no records at national events.

To buy a competetive comp engine for Pro stock truck v6 is 30 to 50k. Most winners buy their engines, have a engine program with a couple of customers, or have been doing it a long time.

Barone has 3 full time cars and has one for sale right now on www,insidecomp.com Ackerman builds engines for his own car and dave rings car.

Cost of entry is not huge, cost of winning is huge. Top racers do a lot of testing and most have dynos.

Good luck, can always use another car in comp.
