What mechanism is used to power the Supercharger in Top Alcohol drar racing vehicles?
Top Alcohol Top Alcohol refers to two different classes in professional drag racing: Top Alcohol Dragster and the Top Alcohol Funny Car. Commonly known as "alky" cars, both are akin in design to the premier Top Fuel classes, but less powerful (about 3500 bhp ). In Top Alcohol Dragster, the cars used supercharged ("blown") engines, burning alcohol (methanol). Top Alcohol Funny Cars look similar to Fuel Funny Cars, with about half the power of a Top Fuel car. In this class only alcohol cars with three-speed transmissions are allowed.
Torsion bar suspension A torsion bar suspension, also known as a torsion spring suspension (not to be confused with a torsion beam rear suspension), is a general term for any vehicle suspension that uses a torsion bar as its main weight-bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a suspension arm, a spindle, or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. The effective spring rate of the bar is determined by its length, cross section, shape, material, and manufacturing process.
