Before you start building your first drag race car, you need to determine which class of racing you will be doing. Different classes are based on several factors including the type of vehicle, aerodynamics, the size of the engine, modifications and vehicle weight. The chassis has to be able to support a sudden take off at the horsepower and torque rating of your vehicle’s engine.
Eliminators and ClassesNHRA has 15 eliminators and some of those have several classes. Funny car, top fuel, pro stock motorcycle, pro stock, top alcohol funny car, top alcohol dragster, super gas, super comp, pro mod and super street all have just one class and the racing is always heads-up – there is no handicap.
Comp, stock and super stock have several classes that are equalized by a handicapped starting system. Top sportsman and top dragster eliminators have just one class, but racers race in brackets. Once you decide which eliminator and class you are racing in, then you are ready to build the chassis.
Engines and AccessoriesDifferent eliminators and classes have different rules for engine size. Regardless of the engine size, you will need top-of-the-line equipment to handle the abuse you are throwing at it. Performance auto parts are built just for racing and should be used instead of stock parts. While performance car parts may be a little pricier than regular parts like you’d buy for your daily driver, you’ll save money in the long run since you have less of a chance of breaking something.
Hoses and FittingsThe small stuff is just as important as the big stuff. Sometimes, such as in the case of hoses, it’s more important. Without water to cool the engine or oil to lubricate it, you’ll have a tough time racing. Instead, you might see the heads heading toward the stands or a piston making a hasty exit from the oil pan. Using high-quality parts, such as hoses and hose fittings from Roadrunner Performance help keep everything together at high rpm.
