dyno numbers

In all seriousness, the actual number does not mean a thing. If you are tuning and the number goes up you are going the correct direction in your tuning. If the number goes down you are going the wrong direction. Like jeff said the important thing is to find a good dyno facility and stick with it so you are comparing apples to apples. One day I hope to make an appointment at all the local shops and run the same car with the same tune at the same temp and than post the numbers. I think some of you would be amazed at how far off the numbers will be. One thing most people tend to get caught up with is peak numbers. How long durring a drag race are you at the specific rpm where your peak power number is? Not long, thats what Dave is talking about with the timing curve i'm guessing. The curve is more important than the peak. Ever see a supra dyno graph? It's no wonder they run high 11s with 600+ to the wheels. Also if the car has a auto with a loose converter forget about a great number. We had an auto car on the dyno once that put down 317 to the tires and ran a 7.1 in the 1/8 mile at 3100 lbs. thats a 11.20 in the 1/4. I have also seen several people over 500 to the wheels that could not break into the 11s.

Just my 2 cents worth!
