The "Top Gearl" mentality has always been MORE POWER! and yet the truth is very different. For a start, the MORE POWER brigade are often ill equipped to manage it, and it really boils down to nothing more than 0-60 bragging rights and straight line bursts of speed. Even then there are some who can't manage a straight line burst.
Having had 4 Midgets, they were more fun than my MGB, and more fun than the V8 MGB. The best Midget of the 4 was the '67. They still had leather seats then, which used to tear across the main bolster. It had done over 90,000 miles, and was a bit of an old nail at 4 years old, but was utterly reliable, and so much fun. .
In this instance I would consider increasing the power by fitting a supercharger to a 1275 Midget......looks like good fun,
