Ignition, Jack Knight S/C C/R Gearbox, S/C drop gears 1:1 ratio, Semi Helical Crown wheel and Pinion 3.44 ratio, Crosspin Diff, Turbo Clutch.

I've got 2 RR results, first being at Aldon where it got 81bhp/5870RPM @ wheels, second was at Richard Longmans following a timing tweak it made 89bhp/?RPM @ wheels (sorry can't be more specific, I'll dig the sheet out later).

Hopefully squeezing a couple extra ponies by dropping the mechanical fan and water pump.
