Very short cam. 18* intake close is 12* earlier than stock, will build a lot of heat and have a very early, short power band. Should make decent torque right off the bottom then fall on it's face quick. That's no fun in a dyna imo.
Agree with all that.

But because our bikes (mine and SquidHead) are similar in setup - Both are 103ci Dynas, both have free breathing a/c and both have 2>1 exhaust - there is a valid comparison, even if it's rough and not identical.
And now back to the regularly scheduled thread...

Pretty much the best stage 1 numbers ever and all only done in 3 runs? Not trying to be a dick, just saying those numbers are not at all the norm, and don't count out cams as a nice upgrade just because your bikes are making similar numbers.

Thanks for your info...I am considering cams as well. Don't know that I will be able to afford them within the next year. But planning now..

I came to this thread because I had the same question as the OP - what's a good mild cam that will give me some bang for my buck?
If I get a good deal I'll jump on it. Until then I'm satisfied with what I have.

Here is a dyno sheet of my 2010 stage 1 96" fatboy tuned and untuned. The 103" makes generally 4-5 hp/tq more across the rev range. The gain from cams is more significant when added to a stage 1 then a stock to stage 1 for comparison. So if your asking if cams are a worth while investment and you like the sound of a loping idle with a gain of at least 10hp and 10ft/lbs which equates to $100.00 per hp and ft/lb? My answer is unequivocally YES. Dollar per hp/tq cams pay dividends.

So...
Back to the original question then:
"what would be the best cams to install, with out doing head work, and without giving too much reliability away, for added torque and horsepower".

OK, this will be my first post. Hoping to get a lot of different responses, and I'm fairly sure I will. I have a 2013 Street Bob with a stock 103", Thunderheader, SE Heavy Breather intake, I'm currently running the Cobra fi2000 with auto tune but will probably go with a SE Super tuner so I can tune it myself, that I haven't decided. But my question is what would be the best cams to install, with out doing head work, and without giving too much reliability away, for added torque and horsepower for all three rpm ranges, low mid and high? I'm an aggressive rider, and open the throttle at every opportunity. I'd like to feel all the power this bike has to offer, because I don't think I am currently, don't get me wrong, it will snap your neck, but I just think a lot more is available with the right set of cams. So your best opinions will be appreciated. And thanks for the help in advance.
