Not much information is available about this particular Porsche 930 engine, other than the beautiful glowing exhaust it produces while under load in the dyno cell, but one thing is for certain — the 930 engine is one of those that forever lives on in the hearts of Porsche enthusiasts worldwide as one of the company’s finest.
The 930 was known to the motoring public as the 911 Turbo and was built between 1975 and 1989, and was the company’s top-shelf model at the time. In fact, it was the fastest production car available in Germany at its introduction.
The turbo technology used in the 930 engine was adapted from Porsche’s 917/30 CAN-AM car to the company’s 3.0-liter flat-six engine, and produced 256 horsepower in street trim — 153 mph and 5.2-second 0-60 times — far better than the standard Carrera.
By the end of its lifespan in 1989, engine output had increased 70 horsepower to a maximum of 330 horsepower, 70 more than at its introduction and directly related to a bump in displacement to 3.3-liters, a four-pipe exhaust system, and an air-to-air intercooler.
The 930’s engine used forged pistons, electronic ignition, and a whopping 6.5:1 compression ratio when it was introduced in 1975. by 1983, Bosch KE-Jetronic fuel injection had been fitted and the compression had been bumped to 7.0:1. Boost hovered in the .8 bar range, which is approximately 11.6 psi. The engine was built around an aluminum crankcase and cylinder head and included a forged steel crankshaft.
Emissions concerns removed the 930 from the US market in 1980, and it returned in 1985 with an emission-controlled engine producing 278 horsepower.
