Elapsed Time and Horsepower Chart

Elapsed Time and Horsepower Chart - How much horsepower does it take to get the time you want

Horsepower Required

Use the chart below to see how much net horsepower is required to run the elapsed time you want. To obtain the rear wheel horsepower simply multiply the number by 0.85. Example: If your car weight is 3,000 pounds and you want to run a 12 flat, the required net horsepower is 343 or the rear wheel horsepower required is 343 x 0.85 = 292.

  • Everyone has heard it a thousand times - BUT IT IS TRUE!! A car with a group of parts that compliment each other will run better than a car with a mismatch of parts. This group of parts is called the combination. This article is designed to help you build the perfect combination. A well thought-out combination will not only make your car more enjoyable but also enhance the drivability and acceleration.

  • Although this may seem very basic to many people, some people don't even know the easy way to check fuses. I've seen people suffer through the big pain of taking each and every fuse out one at a time to see if any of them are burnt. There's a lot easier way of checking fuses without taking them out.

    Ever notice that fuses have two small metal "tabs" on top of them? Those "tabs" or prongs are for checking them with a tester. You can buy a specific tester for this task but an ordinary 12V tester will work.
