Dyno today

[RocketandRollit]

Secondaries removed, triple K&Ns, CAT delete & TORS.
Based on how smooth your charts are, I think I need some work...

The thing I noticed with the other other graph is the torque posted doesn't peak until 3k rpm or so with the K&Ns. On the run by RocketandRollit, although in mph, it looks like it took a bit for the torque to come on.

On mine, with stock plenum and filter, the torque is much sooner, and then drops off in a nice arc.

Both my 13 Touring and SDCC's 06 Classic were done on the same dyno, by the same guy, so that takes at least one variable out of the equation (different tuners/machines).



Hopefully, next year, the header and intake selections will be improving and I can do a little more.

I have been mentioning the low rpm torque loss under 3000 rpm for years.

There are ways to get it back, and then some.

Here is my one to add to the collection,
Downunder here in Brisbane Oz, I had my 06 Classic Dynoed this week, here is the before & after runs.

I have the standard plenum intake modified with a panel filter and a self made custom exhaust, retaining the triple muffler look.

 

[RocketandRollit]

Ok Mr. Tripp, Ozrider's graph shows the same type of loss @ low rpm.
Can you give some direction on how we should proceed to regain our low rpm torque and smooth out that curve?

****! That torque curve is flat. That thing must be a blast to ride.
No doubt that your exhaust / intake combo is working well.

I didn't do the run, it was a guy that came over from the west side of the state for the weekend. I mentioned to him what I wanted, and to reset the trims. I can only hope he did. I am sure he did, he has been doing this for a while.



That trailer was a tight fit for the Rocket.

That definitely looks like Nels' trailer. He's an awesome tuner. I have the good fortune of only being 10 miles from his main location. He tuned my Yamaha Warrior but not the Rocket yet. Nels will be my first stop once I get the Rocket back on the road.

Mine looks a little different

Mine looks a little different

It doesn't look quite as flat or consistent but I reckon the bigger scale on your graph exaggerates the difference a lot

Mittzy,

What air filters are you running?
