Had some extra money so I decided to install the Andrews 48h cam in my 2010 Road Glide. Was already running a Propipe slipon from V&h with the stock 2-1 header pipe and the K & N cleaner with velocity stack (and pc-v) I told the shop I wanted a nice smooth torque band. Results and initial impressions:
1) 86 hp and 106 trq. Slow building torque from the dyno, which doesn't show many ref pts so it isn't very detailed.
2) I was expecting more punch way down low, not sure how much of that was my instructions / the tune (see intro).
3) There is definitely more torque (just not "punch") early on as I was able to accelerate going uphill in 6th gear going 60 at ~2100 rpm, where before I would have downshifted in that situation.
4) There is a distinct sweet spot that starts at 2700 rpm, the bike is eager to go faster- Daddy like!
5) No assessment of mpg yet, going to have to stop blipping the throttle constantly and/or run a couple of tanks thru it.
6) I way underestimated the affect on the sound / noise- huge difference! I am not a loud pipe guy and figured I was pretty safe with the stock header. I could tell a noticeable differnce when they fired it up in the shop and I was inside the store on the other side of the wall. It doesn't sound like straight pipe / no baffles, but it is a low frequency, penetrating sound. Speaking of which...
7) At idle the bike sounds badd a$$, loping sound like you expect from a Harley. The bike also gets louder as you hit the sweet spot at 2700 rpm. Because of my 2-1 pipe the bike sounds like the prop of a plane, with the blades rotated 90% so the blades are slapping the air....
8) There seems to be more vibration in the seat at the light- the tach is skipping around, thus the loping sound.... But, the bike is smooth when riding, with no additional mirror shake.
In summary, more fun to ride and less downshifts. If I am riding solo thru a National Park it is too loud for my taste, but my friends are going to be jealous around town.
