From what I have been able to find out the homie750 (cool saw) is 112cc and rated at 6.96 hp. at 8000rpm.No load rpm is 11-12,000 rpm.Bore is 2.25"and stroke is 1.720".
The 088 is 121cc and rated at 8.6 hp. I don't have rpm or bore and stroke figures available for the stihl.
On paper this looks like a clear win on the part of the stihl.(assuming same bar length and equal chains and users)However not being able to compare the stroke figures the homie could have a possible torque advantage.Who knows for sure?But i'd sure wanna watch that race!(regardless of winner)
