Easier/quicker gear changes

I wonder how much extra power you need to squeeze out of an RP saloon to get it to go at 75mph? I can get mine to run up to 55mph (on the speedo) on the flat on a good day but anything faster than that I think I'd bottle it - it sounds like it's in imminent risk of self destruction which usually makes me back off. Engine is standard apart from 37 head and 1 1/8th SU. Wind resistance must be a huge limiting factor, as it's as aerodynamic as a house brick.

Quite a bit!

My father used to race his with a Shorrock supercharger attached, went rather well...
