The 1966 Season
Hailed as the "return to power" the 1966 season saw the start of the new 3 litre formula.
Some teams were more ready than others and as a consequence a wide
variety of engines and chassis were used ranging from Ferrari's new
purpose built 3 litre V12 (312) to modified 65 season engines which
were bored out to 2 litres.
There were also various 4 cylinder Climax engines plus a 2.4 litre V6 (246) Ferrari based on the "Dino" engine.
Jack Brabham's "Brabham Racing Organisation" had commissioned "Repco"
to build a 3 litre V8 loosely based on an alloy Buick engine. Mounted
in the new light and nimble BT19 chassis the combination would go on to
win the 1966 World Championship.
Although not the most powerful in the field it proved to be a most
reliable contender. A later BT20 fitted with the same engine was
campaigned by Brabham's team mate Denny Hulme.
Team Brabham also ran a BT11 chassis fitted with a 2.5 lt 4 cylinder
Climax engine for Hulme in the first few races of the 1966 season.
"DW Racing Enterprises" ran a similar but privately entered BT11
powered by a longer stroke 2.7 lt 4 cylinder Climax engine in the hands
of their driver Bob Anderson.
A third BT11 chassis was also campaigned by David Bridges Racing and
Rob Walker teams. This car was powered by a high revving BRM 2 litre V8.
