I still need your input here
I posted this in the 'Dyno numbers section' nothing yet. I'm reposting it as a new thread here.
My bike a 2007 RoadGlide with a FatCat 2 into 1 pipe with the quiet baffle. S/E air cleaner (K/N filte). Power Commander III from Jamie/FuelMoto. Dyno run;
Max Power= 73.93 h.p. Max Torque= 86.42
Happy with those results.
My problem. After reading, researching just cam upgrades I settled on an Andrews 26H with S/E adjustable pushrods. An Indy did the work. Dyno #2
Max Power= 84.10 h.p. Max Torque= 89.03
A nice increase in h.p. But, I bought the cams for a torque increase in the 2000-5000 rpm range where I spend most of my time. I really don't feel a difference after the cam install. I don't think the second dyno tune is as good as it can be. Agree or disagree? It looks like the torque dip from 3300-3800 rpms maybe the culprit. I wasn't able to look over the shoulder of the tech guy so I don't know the Air/Fuel ratio. Should I take it back or look for a different tuner? Thanx so much for your input.

I think with a 26 your going to notice the differance with 2 on the bike and its more of a low- mid range cam as in will make passing a little better....1800-5200,21 will give ya a lower rpm torque but not much.
Iam leaning twords S&S 520 cams............

thanx Ranger
I agree with the rpm range, it looks like the dyno has a bit of a flat spot in the area I was hoping for an increase. It's hard to read my chart I know.

I think the 26A would have been a better choice for low RPM power. Doesn't the H stand for high lift? That mean more power at higher rpm's.

Good idea
Will do that. My time b4 Sturgis is short and if I go back to that Indy, I don't want to wait very long to get it done.

chain vs. gear drive
I thought the H meant a stock chain replacement drive vs. a gear drive setup.
