BMW 1M Single Turbo - 0 to 302 kph.

The TwinPower Turbo (also called twin scroll turbo) is a single turbo powered from pairs of cylinders in an alternating sequence from two exhaust down tubes. The Twin Turbo Power has two turbos, each fed by one of the two exhaust down tubes. Reference the below image to visualize the TwinPower Turbo technology. Turbo Repair Inquiry; Product Information. Installation Instructions; Core Return Process. S55 M3/M4 Silicone Charge Pipes Bundle From: $ 349.00. Single turbo kits are the most popular set up for a few simple reasons. The first reason is cost. Turbos are very expensive; for a good turbo you could pay about $1500-$2500 or more. This cost jumps substantially when you add another turbo to your kit. Another reason is space. An M4 made 682whp on pump gas. Impressive numbers no doubt, but we recommend keeping these turbos in the 750-850whp ballpark. This is also an excellent turbo option for anyone looking to make low 700whp. All around – it’s tough to go wrong with these turbos.

The BMW N55 is a turbocharged straight-six petrol engine that began production in 2009. The N55 replaced the BMW N54 engine and was introduced in the F07 5 Series Gran Turismo.^[1]

The N55 was BMW's first straight-six engine to use a twin-scroll turbocharger. It also won three straight Ward's 10 Best Engines awards in 2011-2013.^[2]

Following the introduction of the BMW B58 engine in 2015, the N55 began to be phased out.^[3]

BMW S55 engine is a high performance version of the N55, which is used by the F80 M3, F82 M4 and F87 M2 Competition.

Design[edit]

The main differences between the N55 and its N54 predecessor are the use of a single turbocharger, the addition of Valvetronic and the type of fuel injectors. Whilst the N54 used a twin-turbo arrangement, the newer N55 uses only a single twin scroll turbocharger.^[4][5]Valvetronic (variable valve lift)^[6] is claimed to improve throttle response, low-rev torque, exhaust emissions and to reduce fuel consumption by 15%.^[7][6][8] The direct injection system uses solenoid-type injectors, instead of the piezo-type fuel injectors used by its N54 predecessor. The piezo injectors were more expensive and BMW decided they were not worthwhile outside of Europe, because the potential benefits of lean-burn operation could not be fully realised.^[6]

The exhaust manifold design, called Cylinder-bank Comprehensive Manifold (CCM) by BMW, aims to reduce the pressure fluctuations to reduce throttle lag and exhaust back-pressure.^[9] The twin-scroll turbocharger uses 2 sets of exhaust duct to turn 1 turbine wheel, with cylinders 1-3 and 4-6.^[10] The engine management system is Bosch MEVD 17.2, and compatible fuels are ROZ (RON) 91-98 octane (minimum RON 95 is recommended),^[11][12]

As per the N54, the compression ratio is 10.2:1, the bore is 84.0 mm (3.31 in), the stroke is 89.6 mm (3.53 in) and the displacement is 2,979 cc (181.8 cu in).
