Phillips was a renowned engineer, his uncle was a development engineer and works rider at
JA Prestwich Industries Ltd (JAP), and was instrumental in the development of the JAP engines used in speedway. Stan Greening was developing an engine specifically for speedway but the results were not impressive after testing by Australian riders
Billy Lamont and
Vic Huxley. Greening and Phillips stripped down Phillips'
Rudge bike and used some of the ideas in that engine with the new one of their own. When Phillips rode the bike at a meeting at
Stamford Bridge stadium he beat the track record time. The JAP engines remained in use until the mid-1960s. Phillips was also known for what he termed as his
fuel injector, a carburettor replacement mainly intended for motorcycles and scooters. == References ==
