Moss has a kit now. Back in the day, there were two or three major aftermarket kits. Shorrock and Judson are the two I remember. Eaton might have made one.
But for the weak crankshafts, the engine was well suited to these. 8-to-1 compression, small valves, etc. Shorrock claimed TDs could achieve a blistering 90 mph with the supercharger bolted on. I suspect that translates to about 70, maybe 75, horsepower.
Yeah, but does your 1776 huff and puff? It’s not just about horsepower. It’s about style.
The MG K3 Magnette sported a Marshall supercharger in front of the radiator much like a baby Blower Bentley. It generated 120 hp out of a 1087 cc Woseley Hornet 6 cylinder motor that produced 39 hp normally aspirated. It won its class at Le Mans and the Monte Carlo Rally and won the Ulster Trophy with Tazio Nuvolari at the wheel. . . in 1933.
