RE: Have evolution .46 for Morris profile
Evolution .46
Displacement: .455 cu in
Bore: .867 in
Stroke: .770 in
Total Weight: 19.52 oz
Crankshaft Threads: 1/4 x 28
Benchmark Prop: 9x6
RPM Range: 2,000-16,000 rpm
.46 FX
(OSMG0546)
disp 0.455
bore 0.870
stroke 0.770
rpm 2,000-17,000
weight 13.2
... The big thing I see is the 6 ounce extra weight and a loss of 1000 rpm from the evolution to the os. Is there something else I should look at?
tailspnr.. I have no idea what the muffler bolt pattern looks like on the tower muffler or the os. I would have to take it to my lhs to compare. I guess that could bring it up to where it is usable? How is that compared to the mac.
That is good news by the way on the evolution. ifly04 .. did you do anything special other than the pipe? And.. where can I find this pipe?
