In BMW circles both noelle motors and the 750i are legendary names. Company founder Karl-Otto Noelle was the former head of engine development at Alpina in the 1980s where he extracted impressive power from engines, sometimes using turbocharging.
Another legend among BMW enthusiasts is the 750i, a badge that first appeared on the bootlid of the V12 powered (E32) 750i. The current car that wears this label only has eight-cylinders, but thanks to a pair of turbochargers, direct injection and Valvetronic it generates a much more potent 450 hp and 650 Nm.
Exploring the significant headroom in the bi-turbo V8 (N63B44) motor, the engineers at noelle motors mapped out a three stage upgrade programme.
With just software optimisation the noelle motors S1 conversion takes output to 570 hp with 740 Nm, which shaves the benchmark 0-100 km/h sprint from the standard cars 4.7 to 4.0 sec.
The S2 conversion combines a free-flow exhaust downpipe with the appropriate ECU remap for 600 hp, 770 Nm and a 0-100 km/h time of 3.8 seconds.
The peak of the noelle motors 750i engine upgrade programme is the S3 version, which adds modifications to the turbochargers to the larger downpipe and tailored ECU remapping for 629 hp and 820 Nm of torque. This delivers a 0-100 km/h time of just 3.6 seconds, placing the noelle motors 750i firmly in the super sports car league.
