M8 Softail owners .
#81
I gotta quit looking at this thread, you guys are gonna make me do something stupid. I can't go deeper in debt. When the new Softails hit the dealers floor I went in to look. I liked the Fat Bob the best. Then on a later visit the Fat Boy was the ONE. Then on another day there was a white Low Rider on the floor. Oh yeah, especially after I sat on it. It fit me to a T. This was at 3 different dealers all about the same distance from me. All three of them tried putting key fobs in my hand. From everything you guys are saying I am not getting on one of those temptresses.

I am liking that engine guard bar. Where didnyou get the rear helmet holder? Lastly, what cam you going with? I just installed the power cam. Haven't really gotten on it to see the improvement yet. Looking at the HD book though, seems the tq cam really doesn't do much for the 107.

If you're looking for roll-on passing power, the torque cam gives a good improvement in the rev range up to 4500. If you're looking for high-RPM horsepower, the HP cam delivers more of that. But the HP cam doesn't beat the torque cam (in either HP or torque) until 4500+ RPMs. So if you rarely ever venture up that high, you wouldn't see as much benefit from the HP cam.
Both offer quite a bit more hp and torque than a stock bike, so you'll see improvements throughout the powerband no matter how you ride. For example, at 4000 RPMs, the stock bike is putting out about 95 ft/lbs, the HP cam is delivering about 104, and the torque cam is 108. So there's benefits to both. And in the high-horsepower range there's still benefit to both; at 5500 RPM the stock bike is about 76 hp, the torque cam is 94 hp, and the HP cam is 100 HP. So they both have benefits throughout the rev range. It's just that the torque cam's improvements are disproportionately in the range from 2000-4500 rpm, and the hp cam's improvements are disproportionately in the range from 4500+ RPM.

It depends on what rev range you're talking about. As for torque, the torque cam provides a lot more than the HP cam, up until 4500 RPMs. The torque cam peaks at about 112 ft/lbs, the HP cam peaks at about 104 ft/lbs.

Good break down bro. Greatly appreciate it. I think I chose the right one for me then. I am a higher rpm person. I was more aiming to get the bike to 100 hp and 100 tq. I have always been a fan of 1 to 1. I rode the bike a little yesterday and didn't feel any loss of power down low. So this had me thinking. But after your explanation it makes sense because the HP cam still out performs the stock cam in both areas.
Cheers guys.
