Here's a guy that really got a bad bite from the modding bug.
The bike started life as an Ariel Square 4 (Edward Turner's other masterpiece), but RR engineer Dick Foster-Pegg didn't like it's performance on the pool petrol used in WWII.
So he did a little modding.
He fitted twin superchargers, twin cranks, twin oil pumps, twin carbs, dual drum front brakes, water cooling, telescopic forks, & a sprung rear-hub, all of which was ground-breaking stuff in the 1940's.
He was pretty clever about the design too. The superchargers were actually ex-aircraft Turner vacum pumps, reversed so they blew.
Pretty cool eh?
The bike was sent to the US in the '50's, & I don't know what happened to it after that.
My thanks to the Classic Motor Cycle magazine, for the article that enilightened me to this bikes existence.
I know it's not a twin, but it is a double twin.
& it is one of Turner's babies.
So I thought it might find a receptive audience here.
