Spotted this at Shelsley on the Saturday of the Gathering. Lotus 23 chassis, but the engine is a bit unusual. It's a flat 12, 2 stroke, aircooled, 1483cc engine, producing an estimated c220bhp at 10,000RPM.      rotorvicinfosheetdetail by cianha!, on Flickr Pottering about the paddock: And here's the launch captured by someone else on the day: www.flickr.com/photos/48912169@N00/7822434384/ |

it looks like 6x Ariel arrow engines engineered together to me ?  I only know because my dad had two 60's Golden Arrows I rode one of them in the 2006 Thundersprint ;D  |

excellent technical innovation of that era
love ariel arrows from my youth
seen a few racers including the melvyn prett replica built in Sandwich Kent late 60 s plus isle of man tt entrants of the 60 s era as well
just love all them engines side by side
for me a bit of true british engineering spirit we are known for

Nice & amazing, V12 with separate crankshafts. The way the cooling fan was mounted on the engine cover is an nice solution.
