Power Kit (I-no. X51)
Revision:
This bulletin replaces bulletin Group 1, #8/17, dated July 20, 2017.
This revision includes two additional kit part numbers and related information.
Model Year:
As of 2017
Vehicle Type:
911 Carrera S (991)/911 Carrera 4S (991)/911 Targa 4S (991)
Concern:
Subsequent performance increase to 331 kW (450 HP)
Engine Type:
Standard engine MDC.HA with engine power of 309 kW (420 hp)
Subject:
ONLY for vehicles with Sport Chrono Package (I-no. QR5)
Restrictions:
ONLY approved in conjunction with sport exhaust system (176).
ONLY approved in conjunction with optimized ventilation of rear axle.
Comes as standard on vehicles with Porsche Ceramic Composite Brake (PCCB = 450) or rear axle
steering (470).
General
information:
A parts kit is available for increasing the performance of the standard engine.
Increased performance is achieved by implementing the following measures on the engine:
•
•
New exhaust turbochargers (referred to hereafter as turbochargers) with larger turbine/compressor
wheel diameters and a higher volume.
Modified maps for the DME control unit.
The following additional modifications are also required and the following preconditions must be met on
the vehicle side:
•
•
•
New engine compartment cover with carbon inserts, painted Titanium Grey.
Sport exhaust system incl. tailpipes (if not already fitted).
New wheel carriers with ventilation openings and spoilers on the rear axle (if not already fitted 
vehicles with PCCB or rear axle steering).
The higher-performance engine is also available straight from the factory for the new vehicles mentioned
above under Exclusive option No "X51".

Engine
Break-in:
Engine speeds greater than 5,000 rpm are not permitted over a distance of 310 miles (500 km). The
maximum engine power of 331 kW (450 hp) depends on the total mileage of the engine at the time of the
retrofit and is achieved at a total mileage of approx. 6,250 miles (10,000 km) or higher.
Warranty:
Information
In order to provide a warranty for the retrofit, the dealer must create "Power Kit (I-no. X51)" documentation for the relevant vehicle in the "Porsche Quality Information System = PQIS".
Retrofitting: Warranty in accordance with the Repair Conditions and the Warranty Conditions for Original
Porsche Parts.
New vehicle with Power Kit (I-no. "X51"): Vehicle warranty in accordance with Porsche guidelines.

Information
Before programming the "Engine immobilizer" and "Digital engine electronics = DME" control units, the
performance class (P class) must be changed for the vehicle to be converted. This is done by PORSCHE
AG!
When ordering a Power Kit, it is important therefore to send the following vehicle data to Porsche by
submitting a TLAR:
•
Part number of the retrofit kit
•
Vehicle identification number (VIN) of the vehicle to be converted
•
Order number used for ordering parts
For further information: see also  Figure 2.
