Kurt Smolik, regardless of how he does business or whatever his reputation is, has been getting involved in the Phantom 85. He decided to put an out of the box V3 phatom on his small engine dyno. This is on an engine that he claims is "broken in" but he also tells people 1 tank of fuel is all it takes to break these in, which I vehemently disagree with. I even told him as much by pointing out his head temps. My Phantom ran hot for the first 3 tanks or so, and once everything finally wore in it started to run cooler, but hey what do I know, right?
"Very interesting . Peak torque 4.3 at 3500 then dies off . Peak hp 4.97 at 9000 rpm. Head temp 430 degrees. Peak rpm 12100"
Anyway, the power figure and where the torque peaks both make perfect sense to me given my first hand experience with an MS460 saw. This is exactly how most Saws deliver their power and torque. The small differences in the ports and port timing between the real Stihl design and the Phantom, mainly the smaller intake side, are what I can easily point the finger at as to why the Phantom makes 5hp instead of 7hp like the saw.
It also shows that there really isn't much point in going past about 9500rpm. I would say the taking the engine to 12,000rpm also contributed to the high head temps.
