OK sports fans, here's the exciting results of the idle bar/ Bru-line tests:[ul]
[*With Bru-line filter........................11,970 peak]
[*Without filter................................12,360 peak]
[*with #8 O.S. ...............................12,360 peak...................Idle 2,100]
[*with Idle Bar................................12,360 peak...................Idle 2,100]
[/ul]
If I flew in dusty conditions, I sure wouldn't worry about 400 peak rpm. If I was racing, the filter would stay in the junk box.
Edited to add: It was much cooler and less humid this morning than during my previous run with the 11x7APC. I picked up 600 rpm from the earlier test.
