New off the roll 33RS was 6 seconds in the same cut. I converted it and am about a second better. That's nearly 20% gain which seems like a lot to me. That being said some of my cutters look as good as Dolkitas and some don't and the angles and tooth lengths aren't as consistent as I'd like.
I measured the rakers with a depth gauge and they were 35-40 thousandths. Then I remembered why that chain had been hanging up. I set the rakers on the grinder and the bump stop wasn't quite where I thought.
All in all I'm pretty happy with it but know there are still significant gains to be had. Another second off? Maybe with full blown race chain and the saw having more than half an hour of break in. year plus aged red oak is not speed wood.
