The S55 debuted in and was the first mass-produced M Division engine with a turbocharger. However, bmw s55 engine, devotees had nothing to complain bmw s55 engine because the S55 was a fantastic engine and a good basis for the forced-induction engines that would likely power the M vehicles in the near future. Here's all you need to know about the BMW S The N55 debuted in on the F07 5 Series Gran Turismo as the German manufacturer's first mass-produced engine with a twin-scroll turbocharger.

As the BMW S55 engine gets older, we are learning more and more about long-term reliability, common problems, and important preventative maintenance. It's no secret that aging high-performance BMWs need more maintenance than your average vehicle. Many older BMWs, especially M cars, have acquired quite a poor reputation for dependability - particularly when the miles start to stack up. But we don't think it's always deserved. Sure, there are a few examples such as the rod bearings found in the BMW E60 M5's S68 V10 that would wear prematurely, fail, and cause catastrophic engine failure.

The S55 was introduced in in the F80 M3 and F82 M4 models, based on the single-turbo N55 but with a raft of changes on board. Since its launch, it has found its way into the F87 M2 Competition in a slightly de-tuned form, as well as in slightly higher states of tune in the Competition and CS versions of the M3 and M4, while the hottest version was fitted in the M4 GTS. After almost 30 years of high-revving, naturally aspirated engines spread across four generations of M3, with fours, sixes and eights found beneath their bonnets, the move to turbocharged power for the F8x generation of M3 and M4 was never going to be a popular one, but it was inevitable and very much a sign of the times. Spare a thought for both BMW and the S55 — the company and its new engine had an almost impossible act to follow, that being the mighty S65 V8.

At 84mm and The S55 makes just 11hp more than the S65, though it is produced much lower down the rev range between rpm, making it more accessible. The move to forced induction did mean that the S55 was rather better endowed than the S65 in the torque department. Where the naturally aspirated V8 had to make do with lb ft, the same as the N55, the twin-turbo S55 develops a meaty lb ft from rpm, giving it some monster mid-range punch. The engine also employs direct injection, Valvetronic, and double-VANOS and uses a closed-deck crankcase design, which increases rigidity and allows cylinder pressure to be increased for maximum power. Instead of cylinder liners, the cylinder bores of the S55 feature a twin wire arc-sprayed coating, which helps reduce engine weight.

Although based on the N55, the S55 shares little in common. Yes, figures like the 84 mm bore, The core improvement that this brings compared to an open-deck design is added rigidity; this, in turn, allows for higher cylinder pressures and consequently more power output. The cylinder bores also featured a twin-wire arc-sprayed coating — an atomized spray of metal that is a complex but lighter solution than conventional cylinder liners.

In addition to the twin-scroll turbocharger, the S55 used the manufacturer's 'Valvetronic' and 'Double-VANOS' valve timing and valve lift technology, which allowed for linear power delivery over the rev range. Throughout its life, the S55 went through several revisions. Tools Tools.

The BMW N55 is a turbocharged straight-six petrol gasoline engine that began production in The N55 was BMW 's first straight-six engine to use a twin-scroll turbocharger.

ECU tuning can unlock more power from the stock turbos or support bigger turbos for even more power. The solution is to replace the faulty gaskets and seals with new ones. The primary advantage over an open-deck design is increased stiffness, which allows for greater cylinder pressures and, as a result, more power production. However, there are some differences between the two in terms of performance and dependability. Needless to say, […]. Porsche The S55 is a 3.
