SE 204 or 48h....
I know this has been gone through before, and I've looked at an assload of threads, but I'm still not sure..
I have a 2011 FXDC 96" with air cleaner, 2 into 1 and a Power Vision. I will be leaving the stock top end alone. I am thinking either the 204 or the 48h will be good in my motor, but I'm wondering which one would hang on a little longer up top. Seems like the 48h makes pretty nice torque from about 2200 to maybe 5k.
Looks like the 204 comes on a bit later, but maybe the 48h runs a bit stronger as a whole.
I know exhaust can change things too.
How much difference is there in these two cams, and where?

I am not an expert on those two cams but basically, without additional head/valve work you can look at a couple of general categories. The first gives a ton of torque from very low in the rpm range (but runs out of steam relatively early in the rpm band) and the second gives you a broader power band at the usual expense of higher revs. Take a look at the hp and torque curves for each cam to see the differences. I installed a Woods Bros 555 (made by Andrews to a Wood Bros spec) that gives a broad power band but also gives great torque right away.
The 555's go to about 100 ft pounds of torque and hold that while the HP climbs to about 80. Torque is what gets you there, hp is what keeps you there. I set the rev limiter to the stock limit.
The only other things I did were roller lifters, K&N filter and a 2-1 pipe with a tune from FuelMoto created on their dyno for my combination. The results are spectacular.
I would avoid any cam that requires that you rev the motor past the stock rev limiter. Just my approach. The higher you spin it the quicker you will wear it out. Hog motors are great torque makers.

I live about 20, 25 minutes away from Fuel Moto, and I talked with them last year about the 555s when I picked up my Power Vision.
I was told that they'd be soft on power with stock compression. Basically, If I were planning to do head work later, they'd run okay stock, but if I were to stay stock, then the 222s or 48h would run stronger stock than the 555s.
They didn't seem to have good things to say on the 204 but a local indy shop put quite a few in and liked em.

I was also told that the 555s don't like having a shorter 2 into 1 exhaust, which I have. So that steered me towards the 48h, being a bit cheaper than the 222, but very similar, and possibly the SE 204s.

I have run both the 48 and the 204's in a 96". The 204 has a better idle if you're into that. LOL The main difference is the lower end performance. I ran them in a touring bike not a lighter dyna so there is that difference.
The 48 comes on sooner and provides more usable power during normal riding. The 204's don't really come on until 2800+RPM. The 204 is a nice cam if your into revving the bike out more often. or if you're riding solo on a light bike.
The 96" motor is kind of a dog compared to the Rushmore 103's. With it's lower compression I would go with the 48's as a better all around performer.

Gotcha... Thx
Next thing is... Between the 48h and the TW222. Looks like the 222 might be a touch hotter up top than the 48h, possibly?

This is what we are working with. Baffle is 2.5" and head pipes are stepped.

So according to the tune they gave me I get 80hp but 100fp torque.
There is a lot of potential with the 555 with headwork. I got all the torque I wanted and am not straining the motor too much. Your short pipes are another big difference with mine. I wanted the pipe as far behind my ears as it could be and Fuelmoto tuned the plates in the pipe to my parts combo.
But I get the blast of a seriously powerful motor. My best bud has a Heritage Springer, is a Harley mechanic and gets well over 100 wheel hp with his setup.
You can definitely get to 100hp with other cams.
If you find a link to the torque horsepower curves of each cam on a dyno, post em and lets compare.
