Thank you Otter74!
Everyone loves dyno videos right?
I am mid processing some video from the first dyno session and figured I'd share an unedited loaded 2k to 7.5k rpm pull with a controlled ramp up as opposed to a Dynojet pure inertia pull.
You can see me start to roll the drum with no load up to 4th gear, roll into the throttle until the brake holds the engine at 2k rpm while I transition to full throttle. When I get to full throttle it will hold the start RPM until I am out of acceleration enrichment and the motor stabilizes and will then allow the motor to rev to the pre determined 7.5k rpm at a controlled rate of climb.
On this pull I am about 5.5 degrees of total timing away from what eventually made best power and about 6% richer than best power as I snuck up to find out what the engine liked and what RPM it made best power at. As the calibration got to its best power output the exhaust note started to get crisper and happier.
Pardon the 20k cfm exhaust fan and 70 mph air speed cooling fan noise in the video, after a few RPM you can hear the motor start to sing over the fan noise. I am looking forward to trying different exhaust configurations for both power increase and tone.
