So, I recently finished building two Asian 660s I refer to as my Asian Twins, as the Cross P+Cs looked nearly identical.
Built them both almost exactly the same, except I did a more aggressive Muffler Mod on the second one. Totally punched out the back of the baffle (instead of just drilling and enlarging a 1/2" hole) and opened up the muffler more aggressively.
When piss revving them, the one with the more opened up muffler sounded a lot badder, and seemed to respond faster. However, after putting B+Cs on them and putting them in some hard dead Chestnut Oak, I think I like the one with the less aggressive muffler mod better. I think it pulled just as strong, and may have had a bit more low end grunt.
Anyone else do any testing or have similar experiences? Although these were Cross MMWS cylinders, I did not do any additional porting to them, other than cleaning them up a bit.
I guess I will have to do some timed cuts if I get a chance to see what the reality is, but would appreciate hearing what others have experienced.
Thanks!
