1976 Alfa Romeo 33 SC 12 Gr. 6: OnBoard at Imola Circuit w/ 11,000 rpm Flat-12 Engine Sound!

From 19Bozzy92, traveling back to the days before Group C, when Group 5 closed cockpit and Group 6 open cockpit sports cars ruled from the mid 1970s to the early 1980s. This car, was one of the most significant. The 1976 Alfa Romeo 33 SC 12.

The Alfa 33 SC was built in 1976 in order to replace the succesful 1975 Alfa Romeo 33 TT. The main change was made on the chassis of the car because the one of the 33 TT (TT= Telaio Tubulare or Tubular Chassis) wasn’t able to harness the power of the evolving flat-12 engine. The 33 SC was built on a new monocoque type chassis (SC=scatolato or “Boxed”). In 1977, this wonderful car started in pole position and won every race it entered in the 3000cc Group 6 class of the World Sportscar Championship.

The engine is a 3.0-liter flat-12 with a max power output of 520 hp at 11,500 rpm and rev up to 12,000 rpm. A turbocharged version was also developed and constructed, displacing just over 2.1 litres, and that was able to produce 640 hp. Only two 33 SC Turbo were built and they only did two races.

Watch one of the few 3.0-litre powered car in action during the 2017 and 2018 Historic Minardi Day at Imola Circuit driven by the Italian hillclimb driver Max Comelli. As you may have noticed, the car has a very short gear ratio since it was and sometimes it’s still being used by Max in hillclimb races. In this case it was just a brief parade/free practice session.
