Tally began his automotive career as a mechanic working with the Kel Carruthers AMA Grand National 500cc World Championship factory Yamaha racing team in 1975.
Billy also worked for Don Vesco for years during the 90's, not only building racing engines, but as a key member of the LSR (land speed record) team through all developmental stages that began with dual internal combustion engines, to its final incarnation as a turbine powered world land speed record holder for a wheel driven vehicle.
He possesses excellent engineering skills, coupled with his hard driving work ethic and unique ability as an efficient problem solver.
Additionally, he has a severe fear of snakes, as evidenced by his horrified reaction at his discovery of a dead rattlesnake that was placed in a UPS box and re-sealed as if it was a recent delivery to the shop.
A key project he undertook at Techco was the development of Techco's 3 Liter asymmetric twin-screw Supercharger, integrating high-efficiency gas-compression technology first developed by manufacturers of industrial air compressors such as Atlas Copco, Ingersoll Rand, and Kaeser Kompressoren.
