Philip started his 500 career in 1954 in a Cooper Mk V JAP which would have been somewhat out classed by that time. At Brough on 17th April he failed to finish in the heat for the Scratch Race, then second at Cadwell Park on 7th June but a DNF in Final and again in Handicap Race. At this point he upgraded from the Mk V to a Mk VIII from Albert Elliott which was fitted with a long stroke Norton engine for 1955.

At some point during 1956, Philip acquired another Cooper Mk VIII from Cliff Allison, this was modified to something like a Mk IX specification with a single Alfin drum at the rear mounted alongside the centre drive casing. He also used motorcycle engine tuner Bill Stuart to prepare short stroke engines for him, the car being christened the Stuart-Cooper as part of the deal.
1956 through to 1959 proved to be highly successful:
At the end of 1959, Philip graduated to Formula Junior.
