  • Elapsed Time and Horsepower Chart

    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.

  • Building the Perfect Combination

    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.

    How to Use This Document:

  • Fluid Capacities (5.0L and 4.6L)

    For 5.0L:

    • Year 1986 1987-88 1989-93 1993 Cobra 1994-95

    Engine oil -

    		 Total capacity - 5 quarts
  • Which Speedo Gear To Use With New Rear End Gears

    Whenever you change the rear end gears to another ratio (e.g. 2.73's to 4.10's) you have to change the speedometer gear too. Why? Because when you change the rear end gears you also change the ratio between how fast the speedo gear is spinning and how fast the car is actually going.

    Here is a chart to figure out which speedometer gear you will need.

     
  • Fuse Location Chart

    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.

  • Cylinder Head Flow Data

    Wonder what heads to get? Only want to buy them once? Then you are in the right place. Here is a set of flow numbers from some of the most prominent cylinder head maufacturers for you to compare.
