Offenhauser was a company that built 4 cylinders DOHC 16 valves, 4 per cylinder from 1930 until the 1980s. These engines were known as "Offy" and were built upon the principle of a 1913 peugeot's race car engine.






" In 1930, a four-cylinder 151 cu in (2.47 l) Offy/ engine installed in a race car set a new international land speed record of 144.895 mph (233.186 km/h). Miller developed this engine into a twin overhead cam, four cylinder, four valve per cylinder 220 cu in (3.6 l) (3.6 L) racing engine. This would be used in midgets and sprints into the 1960s, with a choice of carburetor or Hilborn fuel injection"

"One of the keys to the Offenhauser engine's success was power. A 251.92 cubic inch (4,128.29 cm³) twin-cam four-cylinder racing Offy with a 15:1 compression ratio and a 4.28125-by-4.375-inch (108.744 × 111.1 mm) bore and stroke, could produce 420 hp (310 kW) at 6,600 rpm (1.77 hp per cubic inch (81 kW/L). Other variants of the engine produced up to 3 hp per cubic inch (137 kW/L). Another reason for the engine's success was reliability; unit construction (no separate cylinder head) meant the engine was not vulnerable to head gasket or cylinder stud problems and allowed for higher cylinder pressures."

"Before turbo boost limits, over 1,000 bhp (750 kW) could be attained using around 120 in Hg (44.3 psi (305 kPa)) boost. The final 2.65 litre 4 cyl Offy, restricted to 80 in Hg (24.6 psi (170 kPa)) boost pressure, gave 770 bhp (570 kW) at 9,000 rpm."

The b-series of the 30's!

Nice to see a "real" engine from that time period.

I have been lucky enough to work on some of these engines they just have such a great induction and exhaust note.Everytime I had one booked in to dyno it we would have a crowd of onlookers turnup.
