People are always trying to compare this saw to that saw even though they are vastly different saws sometimes.
As an example here is my point: It is totally meaningless to compare a new saw like a 7900 with 165 psi + compression to an older saw like a 288 xp which some one pulls out of the shed with maybe 135 psi compression, and then claim the 7900 is a way better saw cause it outcuts the 288.
Also are they tached/tuned to the same rpm? I'll bet most who make comparisons don't have a tach or know what rpm's the saws are set at. If one is set slower than the other of course it will cut slower.
And then to always compare em with 20 or 24 inch bars, as well, is a little foolish. A new 7900 would probably outcut a stock 3120 or an 088 with a 20 or 24 inch bar just based on chain speed since the big saws generally run slower.
Bottom line: comparing a new saw to an older used lower compression saw, even if they are in the same class, doesn't provide any meaningful information.
A meaningful comparison should be as objective as possible. Otherwise it may be fun but the conclusions are really meaningless.:bang:
