This occurs just before the fat part of the torque peak for the ZZ4 engine. For the sake of comparison, let's assume that we'll use a figure of 2,500 RPM for a cruise speed. The above figures don’t mean much until they are plugged into the next formula, which is Cruising Speed. The following formula is used when crunching the numbers: The next step is to calculate the tire revolutions per mile for each car. With this information, we compute the vehicle speeds at a specific RPM number. Here are the basics:įinal drive ratio - transmission 1.00:1 1.00:1 In this comparison, we’ll assume that cars run a ZZ4 crate motor and they both carry 3.08:1 gears out back. For the sake of comparison, let’s "test" both cars with conventional Turbo 350 transmissions (the high gear ratio is 1:1). Let's compare a pair of hypothetical hot rods - one is a traditionally styled car with Firestone 7.50X16s on the rear and the other a high tech with P335-30ZR18 BF Goodrich G-Force T/A tires. Get a wee bit more complex and it’s easy to go too far. What all that means is less can often prove better than more.
