Interesting looking at the SE cams in the P&A catalog

[rich1]

They list one as a torque cam and the other as a power cam. The torque cam is said to make 5% more torque at the very bottom and 14% more torque at 4500 rpm. It makes more power than the power cam up to 3500.  Sounds like an ideal bagger cam. The other thing I find interesting is this gain is evidently with the stock air cleaner and mufflers. Maybe they actually work pretty well in stock form.

Found this on another forum. It show the 107 with SE filter and SE slip-ons.

Good find. Thanks. Looks like the torque cam is the way to go.

I wonder why they didn't use the TTS tuner for the "power" cam but they did for the "torque" cam.

From the looks of torque curve (~~~~~), there is certainly more power available with a thorough tune.
But, to the tuners defense, he may not have the needed tables available to him with the early M8 iteration of TTS.

My bet they did, but just did not write it down in the notes.

They did.  Remember that these are done with stock headpipe with cat converter in place.  Good exhaust and the curves smooth out.

You can gain 10 or so ft lbs by giving it a proper afr table.
Richen the 14.5 higher load areas and lean the 11.8 areas to a more appropriate value like 13.0 to start.

Found on the same site- this is the 107 to 114 stg 3 kit SE Legal

Remains to be seen at witch AFR this new combustion technology produce best Tq/Hp.
No reason to Believe it would be the same as a TC bath tub combustion chamber.

PV already has ability to tune them from what I gather and guys have already done this.

So, with regard to "...Good exhaust and the curves smooth out." it appears the M8 OE exhaust can be considered a good exhaust??
(as shown here):

Just curious.

That's a completely stock as received bike- looks like it works OK for stock EPA application.
