Penso di aver battuto un record. Ho messo l'MPE, e dopo due giorni.....ho rimesso l'originale. Tra l'altro l'installazione dello scarico performance è ovviamente avvenuta in BMW.....ma in 15 minuti netti da solo in garage ieri sera, ho tolto l'MPE e messo lo stock. E' facilissimo e pure divertente.

 

Spiego:

 

all'avviamento con l'MPE la sonorità è troppo rimbombosa e secondo me volgare, ad andature normali tra i 1500 ed i 3 mila giri (80% dell'utilizzo medio) c'è troppo "droning sound" come piace scrivere agli americani. Sopra i 4 mila giri non noto alcuna differenza con lo stock. Onestamente, pensavo meglio per la cifra richiesta, ma mi rendo conto che seppur la mia auto "chiami" un minimo di sound in più, preferisco quello signorile dello scarico stock a quello tuning dell'MPE.

 

Non ci siamo proprio. A livello motori turbo BMW, ho trovato molto bello il sound dell'S55 della M4 con il Competition Pack, che prevede anche un impianto di scarico dedicato che sta a mezza via tra lo stock ed il Performance. Quello che servirebbe alla serie 1 è comunque un impianto dedicato come viene proposto per la serie 3 con il PPK, che un semplice silenziatore posteriore "svuotato". secondo me rovina la sonorità del B58 e no, non vale assolutamente i soldi che costa, stavolta mi trovo in disaccordo con BMW.

Io ho risolto le vibrazioni tra 1500 e 2000 giri del record Monza con un pannello antirombo da pochi euro. Oltre i 4mila giri secondo me il suono del motore sovrasta quello dello scarico, perciò ti sembra stock secondo me, ma non ho esperienza con lo scarico in questione

Io, com'è già stato detto, metterei mano sull'aspirazione.

      Di male in peggio secondo me

      BMW M GmbH has sharpened the race-inspired character of its BMW M5 high-performance sedan with an even more powerful model. The new BMW M5 Competition (fuel consumption combined: 10.8 – 10.7 l/100 km; CO2 emissions combined: 246 – 243 g/km)* sets new performance benchmarks in its segment.
       
      The market launch of the new BMW M5 Competition creates a new product category. In future, BMW M GmbH will offer the most powerful variants of its high-performance cars as standalone models. This new status reflects the individual character of the BMW M5 Competition. It also heralds the latest chapter in a history of success which began with the M Competition package (including power boost) configured specifically for the predecessor to the current BMW M5 – and which the exclusive new BMW M5 Competition builds on convincingly.
      The new BMW M5 Competition combines an ever-present sense of the race track and a suitably rarefied aura with the unruffled ease in everyday use for which BMW M models are renowned. A 19 kW/25 hp hike in engine output over the standard version of the new BMW M5 (to 460 kW/625 hp), even more direct responses and bespoke chassis tuning combine to maximise dynamics, agility and precision.
      The 4.4-litre V8 engine with M TwinPower Turbo technology has been modified specifically for this new application and develops peak torque of 750 Nm (553 lb-ft) across an even broader rev range – from 1,800 rpm to 5,800 rpm. The thrust generated by the new BMW M5 Competition’s engine enables acceleration of 0 to 100 km/h (62 mph) in 3.3 seconds and 0 to 200 km/h (124 mph) in 10.8 seconds. Like the engine’s responses, the aural character of the standard-fitted M Sport exhaust system can be adjusted at the touch of a button. The driver can also use the M Sound Control button to initiate an extremely discreet soundtrack. Model-specific engine mounts with a higher spring rate provide a much firmer connection between the drive unit and vehicle structure in the new BMW M5 Competition. This has a noticeable effect on the car’s responses, the sharpness of its turn-in and the experience of the engine’s soundtrack inside the car. The engine’s power is channelled to the road via an eight-speed M Steptronic transmission with Drivelogic. Added to which, the new BMW M5 Competition is specified with the M xDrive M-specific all-wheel-drive system and the Active M Differential at the rear axle. The centrally controlled interaction between the two systems optimises traction, agility and directional stability. The M xDrive system’s rear-wheel bias provides the ideal basis for a full-blooded performance-driving experience. Added to which, the new BMW M5 Competition supplements M Dynamic Mode with three driving programs honed for use on the track: 4WD, 4WD Sport and 2WD, which switches to pure rear-wheel drive and deactivates the Dynamic Stability Control (DSC). Chassis technology meticulously adapted to the engine’s performance profile ensures precisely controllable on-limit handling. Model-specific features of the chassis include a seven-millimetre drop in ride height, special damper hydraulics and stiffer springs, an increased camber at the front axle and modified toe links and anti-roll bars at the rear. Standard specification for the new BMW M5 Competition also comprises exclusive 20-inch forged M light-alloy wheels with mixed-size tyres. Eye-catching design cues emphasise the exclusivity of the new BMW M5 Competition. BMW Individual high-gloss Shadow Line trim is complemented by the use of high-gloss black for the kidney grille surround, decorative grating of the signature BMW M gills, rear spoiler and exterior mirror caps. “Competition” lettering is added to the likewise black “M5” badge on the boot lid. Black seatbelts with an understated stripe design in BMW M GmbH colours and model-specific floor mats bring a distinctive flavour to the interior of the new BMW M5 Competition. An “M Competition” graphic appears in the instrument cluster when it is starting up.
