Internal rotor ignitions are essential stuff for all Highend engines.
The ignition systems which are used for the serial production are not designed to work at such high revs as seen at properly tuned engines. The HPI ignition system gives a stable ignition signal even at revs much higher than 20.000 rpm.
The much reduced weight at the crankshaft drive gives a much more responsive throttle action. The engine gains a power increase over the complete rev range.
Another advantage of the HPI is the auto advance and retard feature. With increasing revs the ignition timing is retarded to give an easier life to the cylinder. Down the rev range the ignition timing is advanced to give better power and torque. The showstoppers are the two ignition curves which are pre-programmed to the CDI unit. The selection is done by a little switch. Both curves are linear and give a very wide setting range.
The HPI comes with an easy comprehensible instruction guide. You may even buy a coil with 10 W power output seperatly to operate a rev counter or water pump.
