The Dyno was quite amazing. The numbers don't tell the entire story on a saw though. I know we bothered Bill and Eric and took away from their day. For that I'm sorry.
In some cases, a saw made less peak HP but more total HP across a greater range-hence a more usable saw in the real world. Moob's saws tended to do that, not as peaky but with wide flat power curves in the rpm's that you need the power in. His saws were flat out classy, think of a well tuned new corvette vs a suped up drag strip car.
The Dyno definitely brings out the child in most men, that's for sure. I mean who doesn't want to win?
MattyO builds a mean husky 350, his saws did very well. He's the man I'll be asking for advice when I build mine.
For me at least, the Dyno was a way to tell what caused the most power change. Like everyone else, I wish I had the thing to myself for a day.
My most suprising moment was seeing my latest MS360 get beat up by my 036 which was the first saw I've ever ported. My 036 has a nearly no restriction metal air filter on it. So on the first pulls, my 036 pulls 6.5 hp and my 360, 5 hp.
My 360 had a really restrictive OEM flocked filter on it. I swapped in an OEM nylon filter and the saw pulled 6.5 hp at around 9-12k rpm just like my 036. Then we pulled the air filter and ran with none. I was so busy looking at the numbers that I didn't notice how leaned out the saw became. Bill did 3 pulls and than asked me if I really wanted anymore with the saw running like this. Without the AF, the saw pulled to 16,000 rpm with the stock 036 carb and boot. It saw hp's into the 8's, but those values are artificially inflated because of how hp readings are calculated. I'll need to see the final figures on that.
But can anyone deny the surprise that a lower restriction air filter made 30% more usable hp? No air filter 50% more? That's something we can all take home and do something with.
