I am currently pushing 86HP and 105TQ on my 2007 Dyna Lowrider with a 103 kit on it. I have the following on my bike:
Rinehart Exhaust
Harley High Flow Intake
SE Heads
SE 255 Cams
SE Race Tuner
I would like to be right above 100HP and 115TQ. Will the Harley 58mm Throttle Body, Manifold, SE Pro Air Intake 58mm and High Flow injectors get me there?

 

255's are killing you, try SE 251/259 they oughta do the trick after a tune.

 

the heads may be hurting you also,seen alot of SE heads that flow like crap right "out of the box",their fine after some work (easy 105+/110 out of a 103")

 

which SE Heads?

85/105 seems about right for a 103/255 build. Those are pretty short duration cams, and they're just not designed for big hp numbers. Most guys who run them say they'll take that tradeoff in exchange for the off-idle performance.

The heads you have with a camset thats not an epa compliant bagger tq cam will work wonders on your lighter, better geared bike.

 

I have heard that SE 259 Cams ride kind of hard for daily driver. Is this true? I live in the Pacific Northwest and it is always wet. Sometimes too much. How would a Harley 58mmThrottle Body, Manifold, SE Pro Air Intake 58mm and
High Flow injectors get me?

 

Bolting on that big t/body is not going to be the magic bullet.
You'll need to get inside that to get things rolling.
Install a Wood 8, and set the compression at 10.65-10.75,(along with some other work to them) and THEN bolt up your t/body.
115/115 should be well within reach.

Well, hi neighbor.

I haven't done a 259 build (yet), but they're pretty similar to the 251 cams, which I like a lot in the right build. A friend has them in a 95" softail that dyno'd at over 100/100 on a very conservative dyno. That bike pulls hard, and feels strong right off idle. I didn't have anything to do with his build, so I can't speak to the specifics, but it sure rides good.

With your MCR heads and flat tops and a .030 or .040 head gasket, your compression should be somewhere around 10.6, give or take a little depending on the actual chamber volume. I don't see how you can be running the 255 cams in that motor without all kinds of detonation problems.

If you're thinking of doing a cam swap, shoot me a pm and I'll be glad to give you a hand with it. I'm about to be forced into early retirement and I'm fixing to have a bunch of time on my hands.

 

If I run a 259E Cam do I have to worry about any problems with my SE 103
Kit Big Bore Flat Top Pistons? Also, If the only thing I change is the cam what kind of numbers can I expect?
