David Vizard,
Oh yes he of scatter pattern fame
Many an article written by the gent, possible not entirely by research conducted by said individual.
The gent who runs this company who gave more than a smattering of assistance to Mr V over the years.
A quality company
Mike Parry has spent the majority of his adult life in a wheel chair after a racing accident at Mallory Park, a superb engineer and problem solver par excellance' and decent human being as well.
I meet Mr. V on quite a few occasions, while charismatic not quite the same a Mike P imho
I remember we were testing a Yamaha 600 racer on the rolling road, he had fabricated a jig so he could test the complete bike on the rollers (at the time has was using a super-flow bench and engine dynamometer, but he felt he wanted to obtain closer real world objective.
At the time the dyn operator was taking the bike to around 12,500 Rpm and obtaining so pretty decent power figures, however Mike wasn't happy with the results, climbed on the bike himself and took this thing to over 16,000Rpm making around 150 odd at the rear wheel not bad for a 600cc at the time some 15 years ago.
The best normally aspirated mini blocked engine I have ever seen was designed and built my Mike Parry using a 1560?? overbore and stroke, split Dellorto's 45 with special chokes, machined emulsion tubes, and 2nd venturi's fully mapped ignition systems, roller rockers, trick profile cam, 290ish on the inlets and 272 on the exhaust on a 5 port head it ran rock solid 142Bhp@wheels with a 8 port special head it was well overs 160Bhp @ the wheels.
Now these days thats average, however at the time it was pretty special and it stayed together!
The most powerful mini (old style) I have seen was a 16V 2.0 turbo Valhalla Calibra engine pushed to the max around 330@ wheels.
All good fun, though could never stand the things myself!
More of a Fiat 127 sport chap myself where you would spend have your time fighting the corrosion rather than the cam followers wearing on the BL A lump!
