Man, I hate to admit it but I think I cut math class on the day they covered charts and graphs.

Anyone wanna take a stab at explaining how to read the dyno charts?

 

Stage 1 AC
VH true duals
"Custom" Python III's
PCIII



74hp
79tq

 

96 h.p.
96 torque
2005 FLHTI
With S.E. Slip on mufflers and 95" flat tops, S.E.air cleaner, 12.9 a/f ratio with S.E.Race Tuner, Andrews 31G cam, .030 Cometic gaskets, S.E. out of the box stock Performance heads. Will be re-dynoing with the new air cleaner and Super Trapps soon.

 

Usually RPM's are shown across the bottom and the HP/Torque values are shown along the left side. Just follow the line on the chart. The HP and TQ lines are generally different colors. Some graphs show the Air:Fuel (AFR) ratio on the very bottom. The number along the left side of that graph represent the number of air particles to every one particle of fuel.

It would be opening a can of worms to gice an opinion on how the lines for each value should be shaped, but generally the more "area" under each line the better. The exception being the AFR line. This would ideally be as flat as possible somewhere around 13:1 I've been told.

Clear as mud? I'm sure there are others that can explain it better.

Hi, I've got a 2002 FLHt with a Stage one with K+N Hi Flow air filter and SE slip on's It has 67.5 H.P. @5900R.P.M.

 

01' Ultra, 95" Stage II w/ SE heads & pistons and pro pipes. I too do not know which cams I have, but I'm sure about the high comp pistons.

Dynoed at Rod's Performance 93.8 HP 96.5 tq

I will be adding V&H true dual head pipes and Cycle Shack mufflers in a few weeks. It will be dynoed again to tweak for the changes. I may picked up a bit more power!

 

I'm a bit disappointed with the lack of entries on this thread. With all the talk about what exhaust is the best I have not seen any dyno numbers.

 

I'll have my RK back in a few days and post the numbers. Bassani slip ons, SERT, 95" with S&S 510g cams.
