Wal Phillips although a respected speedway rider was an excellent engineer known principally for his injector and carburettor systems.
His interests lay mostly with motorcycle and small car engines
Wal Phillips “Whirlwind”
Our thanks to Mark Spearman who gave us the document with his father Ray’s memories of this engine, this is a synopsis of this document which I understand can be seen in full on Chris Byles's website (Exeter Falcons)
Wal Phillips built this and one other engine in 1933, at the time Wal was using JAP engines for speedway and he was developing a Cotton-JAP for Bill Lacey who raced at Brooklands. Wal decided to develop an engine with speedway and Brooklands use in mind.
The engine proved to be over-engineered and very heavy, the castings and most the machining was done at Blackburne’s engineering works, one of the engines had the flywheel and main shaft integral and the other a pressed and keyed mainshafts. All timing gears ran on ball races, the cam lobes were screwed onto a common spindle so they could be shimmed to adjust the timing. They had roller cam followers and the Magneto a vernier adjustment on the driving gear, rocker shafts ran on needle rollers. The barrel was deeply spigoted into the crankcase and the engine had a total loss oil system.
Wal Phillips fitted one of these engines into a modified Wallis frame and rode it in Australia, he found it too heavy.
The second, unused engine was utilised to modify and repair the first as no spares were available, the remaining carcass was then dismantled and because Wal was still developing the JAP engine his ‘Whirlwind’ engine and remains were in his workshop, if not forgotten disregarded.
Wal moved house a couple of times and the ‘remains’ of the Whirlwind were packed in boxes, the next time a move was looming Ray asked if they should not try to assemble one of the engines, instead Wal gave the boxes to Ray.
Ray says “. I discovered there was no crankshaft or piston, so the engine is now only a shell, also, the camshaft was missing. Possible this was lent out to someone, I will never know. There is enough of the engine to rebuild it, the covers with the name on were missing but these could be re-cast. You can see some of the JAP design incorporated in it. It is a unique engine, and one day it may be back to its former glory”
