Bonnemagic muffler TMR38Φ MJN ST-1 cam.
We measured three times and the power differs each time. This is because we can change the ignition timing settings with the AS Watanabe unit,
so we test which range performs best with each measurement run.
143.6 hp at 6 degrees advance
148.1 hp at 8 degrees advance
145.8 hp at 4 degrees advance
Those are the results we got.
Playing around with the ignition timing is fun too! And if you use a slotted hole, it doesn’t cost anything—
Woohoo!
