Those numbers, particularly the torque, seems too low. A stock twin cam should have approximately 65-68 horses & 74 plus on the torque.

Any adjustments such as a big sucker or SE (K&N) air cleaner would reap another 3 hp. Get the American Iron Sep 2005 issue and you'll see where they got gains of 17 hp with a Power Commander, pipes, and air cleaner.

Get a good dyno guy, too!:hmmm:

If you read,it says ,air cleaner {S.E.} Did not tune because it is going down ! Yes ,I agree that that older bikes make more hp. tq. but this is a 2006. I am sure that I could have picked up 3-4 more hp. but the #s were still low. The tq. line was the flattest that I had ever seen !

No offense fastappy, but you obviously were not aware of the identity of the guy starting this thread.:yes:

Bullet has been working motors longer than I've been alive...and shares more knowledge here than he will ever learn.:clap:

Doesn't make anything you said wrong....it was just funny who you were trying to educate is all.

Thanks for the info.
It's be great if Andrews would finally get their cams done for the 06 Dyna's.
That way I could put a nice gear driven cam and make that FLAT TQ line that the 06 Dyna's have DISAPPEAR.
They keep saying 3 weeks, 3 weeks......

SILVER BULLET,
I know you have more insight than I dream of, I would definetly agree with the above statement. I have always used their product in my bikes with great results.
It just stinks cause in this case I am anxiously waiting. But like the old adage says god things come to those who wait, so wait I will and when their done and tested and ready to go, I'll get the cam in there and ride the hell out of it!
Thanks again for the updates.

my 03 Carburated Dyna FXDX ran:
59.3 HP and 69.9 TQ stock @ 500 miles.
66.4 HP and 75.6 TQ Big Sucker Stage 1 and Khrome Werks mufflers @ 2500 miles.

Both dyno runs were SAE 4th Gear. No idea of the A/F ratio but the carb was rejetted after the aircleaner and slip-ons.

my 04 Injected Dyna FXDX ran:
59.1 HP and 69.2 TQ stock @ 3000 miles.
71.7 HP and 81.5 TQ SEAC, Stage 1 flash and Hooker 2:1 (Torque setting) later the same day.

Both dyno runs were SAE 4th Gear. The A/F ratio was as high as 16:1 at 2800 and below, 14:1 from 3000 to 4700, and dropped gradually to 12.5:1 at 6000.

Hi Silver Bullet!

On the bike you dyno´d, was the ECM in stock condition or did you do anything to the mixture? Was the bike running well enough or did you have to adjust the mixture?

I currently have a S.E. aircleaner and S.E. Torque Slip Fit Mufflers and a stage 1 burn on my 2006 Street Bob but I´m looking at Cycle Shack Slip-on mufflers for better sound. Do you think my mixture would be ok with the stage 1 burn or will I need an adjustment? (The bike is running ok for now, haven´t run it in high temps yet)

I know it´s a little hard to diagnose these things at a keyboard, but with my current and proposed setup being pretty common I´m hoping you will have seen something like it before.

Thanks!
Sponk

Are the 2006 cams in the Dyna's different ? Lift,duration,etc.

Intake open; 4 deg. ATDC
Intake close; 43 deg. ABDC
Exhaust open; 40 deg. BBDC
Exhust close; 2 deg. ATDC
Int. duration; 219
Exh. duration; 222

Didn't get the lift, and with numbers like that it should be good for a blower, LOL

2006 Dyna cams are a little different

Many of you might be aware of this by now, but I will tell you anyway. The 2006 Dynas have hydraulic tensioners instead of spring tensioners. This is a fantastic upgrade for durability (hydraulic control vs. 30lbs constant tension from spring). The new tensioner technology requires a slightly different grind for clearance. The durations/lift/etc. will be identical however.

I spoke to Ralph (technical Guru at Andrews Products) yesterday, and he said that with hydraulic tensioners, the 2006 Dyna chain-driven cams will perform as well if not better than gear-driven cams.

Andrews will be shipping cams sometime next week. FYI - he also placed a TW37 set into a 2006 FXD (with absolutely no intake/exhaust/ECU modification) and he got 71hp. Apparently, the new closed-loop EFI ran like crap for just a minute, but it corrected itself (just like a closed-loop system should).
