So we recently went to visit our engine builder, Frank Anderson of Anderson Racing Engines (Bath, UK) to see how things were going. Not long now I think... everything laid out and spotlessly clean, balanced and polished to perfection...
The original was 1192cc, with an almighty 30hp. 64mm crank x 77mm pistons
This is 69.5mm crank x 78mm pistons, giving 1328cc with forced induction at about 8 psi... hoping to squeeze out 60hp without too much effort.
