    Calculating HP from 1/4 mile time and weight...

    i've used this formula with good success. If the car is properly geared (finishing the 1/4 mile 3-400 rpms past hp peak)you should be able to get a fairly accurate result using this: hp= (mph x .00426) cubed x weight this would result to about 350 hp i like...

    Torque calcs for 1st and 5th or 6th gear

    one thing that joest forgot to include in his calculations is a method of providing a common denominator concerning tyre diameters. When comparing 2 cars if both have similar torque outputs and overall gearing,the one with the shorter tyre will have greater torque reaching the ground and will of...

    High compression with large cams??

    if a "large" cam is used on a low compression engine, a lot of the cylinder pressure will be lost on overlap which is the period where both intake and exhaust valves are open. This is especially true at low rpms. That is why the cranking compression lowers when you install the bigger cam in an...
