I have been reading an American book which relates the story of Brit Tony Vandervel
who apparently developed a watercooled Manx Norton engine. This,in tests,proved to produce more power than the standard Manx engine so it formed the basis of a Four cylinder Manx Norton engine which was developed as a Racing car engine....

Have any buffs out there any information on this as it is news to me but of great interest.

Where is the watercoled single now and is the racing car in a museum anywhere in the UK ??

Please help
