NASCAR Whelen Modified Tour cars are substantially different from their Sprint Cup counterparts. Today’s cars are based on tubular chassis built by fabricators such as Troyer Engineering, cialis generic drugstore Chassis Dynamics, best viagra troche Spafco, and Raceworks. Bodies are related to their passenger car counterparts in only two ways. There is a “manufacturers” logo placed on the car, and a logo indicating the type of road car it is alleged to be. Neither logo is actually associated with the actual manufacturer of the race vehicle. Largely fabricated from sheetmetal, with the front wheels and much of the front suspension exposed. A NASCAR Modified is eleven inches shorter in height and over twenty-three inches wider than a Cup car. By rule, Modifieds weigh at least 2610 pounds (with additional weight for engines 358 cubic inches and larger) and have a wheelbase of 107 inches (2,700 mm). They are powered by small-block V-8 engines, usually of 355 to 368 cubic inches displacement, although larger or smaller engines can be used. Engine components are largely similar to those used in the Sprint Cup Series, but Whelen Modified engines use a small four-barrel carburetor (rated at 390 cubic feet per minute, about half the airflow of previous Modified carburetors), which limits their output to 625 to 700 horsepower.
