Harrop 2300 supercharger to Optimiser 6500

[PeeBee]

This deserves an youtube video of the beast chugging down the road like a road-train. In-cab. No instrument readings. Just the GQ bonnet, the road and the sound!

Its funny the engine does not sound anything like the hollywood styled soundtracks. The supercharger at revs is quite a 'zinggy sound' not a Mad Max thunderous roar. It does however project an air raid siren howl forward when I am driving, absolutely howls, can be heard from 500m away easily.
