This race engine produced 470 PS (350 kW; 460 hp) in Procar specifications. In contrast to the M88, the M88 / 3 in the BMW M635 CSi and BMW M5 and in the BMW M745i (South Africa variant) is built in the traditional way , namely in the front - which of course is mainly because they were already in production as front-engine vehicles with rear-wheel drive . [10] The Kugelfischer fuel injection was replaced with Bosch Motronic producing 210 kW (286 PS; 282 hp) at 6,500 rpm and 340 N⋅m (251 lbf⋅ft) at 4,500 rpm. The BMW M88 is a straight-6 DOHC piston engine produced from 1978-1989. The engine is now equipped with an idling control valve controlled by the Motronic , with a lambda probe located in a connecting piece of the otherwise double-flow exhaust system keeping the fuel-air mixture exactly at lambda = 1 . The BMW E23 is the first generation of the BMW 7 Series luxury cars and was produced from 1977 to 1986. The M90 sold in Europe and most other markets (except North America) used a compression ratio of 9.3:1, did not have a catalytic converter and produced 160 kW (215 hp). BMW engineers used DOHC valvetrain on a production engine for the first time on the M88, with the camshafts driven by a single-row timing chain. It was built in a 4-door sedan body style with 6-cylinder engines, to replace the BMW E3 sedans.From 1983 to 1986, a turbocharged 6-cylinder engine was available. The M88/1 engine was modified for use in the E24 M635CSi and E28 M5 and was known as the M88/3. This race engine produced up to 670 kW (900 hp).[8]. For Group 5 racing, the M88 engine was turbocharged and became known as the M88/2. It is based on the DOHC version of the BMW M49 engine, which was used in the BMW 3.0CSi racing cars. [8] A dry sump is used.[9]. The M90 sold in Europe and most other markets (except North America) used a compression ratio of 9.3:1, did not have a catalytic converter and produced 160 kilowatts (210 hp). The M88/3 was also fitted to the South African 745i, due to packaging problems with the turbocharged M102 engine which was used in other markets.
