I have to jump in here. I posted my dyno sheet a few days ago in the SEEG forum and put a note in the twin cam forum. I don't know what the difference between SAE and Standard is and quite frankly don't care. All I know is that my bike runs stronger and pulls harder throughout the rpm range with Freedom Cams. I don't drag race but appreciate the extra power when passing or riding in the mountains. A lot of folks get caught up in numbers but I'm more interested in rideability.
As far as the difference between Freedom pipes and Rineharts I've had both. There is an actual physical difference between the two in that the Freedom pipes have a longer front header pipe which extends down lower and almost below the cam cover. Remember some folks were having problems early on with the billet brake pedal touching the pipe. That fitment problem resulted from the longer header pipe. There may be other differences but I haven't measured the length and width of each pipe segment so I don't know for sure. I haven't pulled the baffles in my Freedom pipes but if I were to guess they are probably using a smaller baffle. I actually went with Rineharts quiet baffle on my Road King and it's powerband was similar to Freedom's i. e. a steady increase in power as opposed the the sudden increase at about 4000 rpms as I experienced with stock Rineharts and the 2 1/4 " baffles.
I don't know why Brad or Mark won't release their cam and pipe specifications. Evidently they view them as proprietary. I'm sure that info would be helpful to those here who actually understand such concepts as lift and duration and how they relate to our engine. As I understand it Freedom sought to come up with bolt in cams for the 103 that increased power through out the rpm range w/o the need for additional engine work. I think they suceeded. Zippers cam looks to be similar. I expect it will also be suceesfull. Everything I've heard about Zippers has been positive. Unfortunately, an near as I can tell they are located somewhere back east and the liklihood of me traveling to their shop to get some work done on my bike was not very high. Reno, on the other hand is a mere 600 miles from my home. It was an easy choice for me.
I posted my dyno sheet here if anyone is interested. If anyone can explain , in non-technical terms, the difference between SAE and standard, I might be persuaded to try and assimilate that info.The lower numbers on the chart are with a Dyno run done last may with Freedom pipes, SE aircleaner and a PC. The red line is after the Freedom cam install. Incidently my wifes bike with a SE stage II build went from 71hp to 90 hp and from 77.7 foot lbs of torque to 97.7 foot lbs with just the addition of the pipes and pc.
