Dinan Engineering tunes the BMW 550i

The BMW 550i has received an aftermarket kit from Dinan Engineering which is compatible with both the RWD and AWD versions of the car. They focused on the TwinPower 4.4-liter V8 engine and increased its output from the stock 400 HP (294 kW) and 609 Nm (450 lb-ft) to no less than 542 HP (398 kW) and 795 Nm (587 lb-ft) of torque. The additional power was obtained by tuning the exhaust system, mounting bigger intercoolers and turbochargers, together with remapping the ECU and installing a high-flow intake manufactured from carbon fiber. After the changes were made, the BMW 550i was able to hit a top speed of more than 322 km/h (200 mph).

Dinan Engineering also conducted several other modifications to the BMW 550i by mounting lightweight forged wheels, negative chamber front control arms + low compliance rear control arms, as well as custom lowering springs. There’s also a Brembo braking system, carbon fiber mirrors / rear spoiler / front fascia and a limited slip differential.
