If there ever were wild engines at racecourses they were the monsters engineered by visionairies of what could be done for classes C to X. Back in the mid 1960s there was a GM Corvair flat aircooled 6 mounted on a outboard racing tower and speedmaster that could clobber 100 mph. Later there were Twined Konigs both parrallet and also verticle mounted with 8 cylinders in all running. Some worked and some came apart and ended up in the drink. All manner of variations have come up since.

One fabled extreme racing engine was the British Anzani NOA Class C (30 cube) alky developed by taking 2 – 15 cube Anzani Alky Class As and with a engine coupler mounted side and across from each other with one set of cylinders facing front and the other the rear geared to run either firing a cylinder of of 4 available from one or the other motor every 90 degrees or firing 2 every 180 degrees. The Anzanis were the cast iron blocked loop charged rotary valved engines that started and accellerated loop technologies in all 2 strokes in air, water or dry land getting speeds exceeding 100 mph on a 322CC B-Alky hydro back by 1971!

These engines were using methanol with nitro loads exceeding 50% by volume. This Bill Tenney (Crystal Bay, Minnesota) built twin engined monster according to sources was driven my Floyd Harris in C-Alky runabout who took championship honors with it according to sources, 1962, 63 and 64 when it went out of use for what ever reason. The same sources told me there is only one person who knew how to fire the 175 odd pound engine beast in having the strength to do it too.

This engine has been in the restoration works for a couple of years now and with thanks to Tim Chance (a long time racer) came up with a picture to restore it by. With that not only will the monster be configured but it will be in great shape to start and run being reconstructed with more than 50% NOS Anzani parts. I can already see some people waving off the effort to lift it and start it with a rope on the flywheel of one engine that fired the other when it took!

Its 11,000+ operating RPM with the pipes it used would seem nothing you would want to be too near for too long when it roared to life.

There will be a future pictorial on this twin blocked engines resurection posted here, it may be the only one ever to exist again, but if you want some advanced views of this extreme engine from its origins as a twin cylinder A or B racing engine or the types and kinds of components it was made from, log on to the ******************** website and search British Anzani.

These engines did much more than provide aeroengines for the first flights of aircraft from France to Britian and in reverse in the early 1900s, in 1st World War fighter and bomber piston aeroengines, or in motor cycles in the 1930s, they were the loop charged revolution in 2 strokes on water that kick started all that followed them worldwide in all manner of applications since circa 1960. They went past the 100 mile an hour mark first in their class by 1971 and by 1981 some were going to 106-107 miles per hour. If your Yamaha, Merc, Konig, Quincy Flathead, Harrison, Suzuki or OMC is a looper, Anzani led that to happen years/decades after they, Anzani did it through the developments of the Bill Tenney’s and Jim Hallums and their friends of the engine and sport that took them there in their heyday as racing engines in North America in Alky classes.
