Ultra XP850 Almost there!
I spent some hours last night on the dyno testing booster startup point in rpms vs main air bleed size. I tested at no load, high 40's and mid 60's ftlbs torque. My results were that booster startup occurred within 100 rpm regardless of main air bleed size. I tested with .025, .035 and .045 bleeds. I even took the bleed out and it was still within that 100 rpm. My test could be flawed. If it is someone please point out my error. Also maybe someone could try to repeat this test on their motor and report back with their results. I'm starting to think that the main air bleed isn't the cork in the bottle when it comes to booster startup. I attached a photo of my results. please excuse the sloppy writing.
This is a repost of the test I did.
