"I decided that I wanted the power in the lower part
of the rev band. To gain extra torque 2 rally camshafts were installed. The
cams are 290 degrees at the intake and exhaust side. At the same time the
chain tensioner out of an euro E36 M3 3.2 litre Evo was installed. Because
of the fact that this unit doesn't use the spring, the chain rattle at
start up will never be a problem again. The brakefluid reservoir needed to
be installed elsewhere because of the airbox. This didn't prove to be a
problem as all hardware needed for moving the reservoir was supplied in the
airbox kit. The initial tuning of the Alpha-N unit was performed on the
street with the help of a laptop. The big advantage for tuning on the
street is the possibility to maximize the acceleration out of corners. The
full throttle adjustments were performed on the dyno. The dyno figures
showed a maximum power output of 270 hp. According to the tuner this could
have been 10 to 15 hp more if the head had been flowed. This would however
have influenced the robustness of the motor negatively. And I rather prefer
an engine with a few hp less, but that holds together."
