SE-255 vs Andrews 26
SE-255 vs Andrews 26
After weeks of reading cam posts my head is spinning seems like there will never be a right answer for a cam. Yes I've used the search function
After weeks of reading I think I have it narrowed to the 26 and the 255 seems like they pretty much do the same thing although the 255 is cheaper. It would be going in a fuel moto stage one 07 96" road king. I know neither of these cams are hot rods I just want some more torque in the basement and up to 4500 rpm so lets here it gurus. Oh and I plan on wrenching on it myself and going thru the rocker box to reuse my stock rods. Also should i be swapping out my lifters when i put in the cam, seems like both the cam and lifters are wear items and should well, wear together?

255 cams
The 255 cams close the intake valves at 25 degrees ABDC, very early. That means torque, and lots of it. The 255 is the king of the torque cams. It has good specs for 1800 to 4500 rpm, plus .550 lift at the valve to make use of every bit of the headflow. The 26 closes at 35? less torque, and less lift.
I put the 255 cams in my 103 2011 FLHTK and they are exactly what I wanted. We ride two up a lot, and the bike weighs 901 lbs ride ready.
The only other choice for me would have been an Andrews 48h, because reports say it mirrors the 255 up to about 3000 to 3500 then pulls away by a few hp. But they cost more, so I went 255s.

Comparing to the 255'syour next closest Andrews Cam would be the 21's. ( Edit: Thanks for the info on the 48's ! That will be on my short list for the next bike !) Closing the intake at 30-31 degrees abdc. Read this article by engine guru Joe Minton in American Rider. He's talking about the Andrews 21's.

Although this article is geared towards the TC88's, he wrote a subsequent, very technical article in the Feb, 2010 issue of American Rider about this cam.
Here's the dyno on my '06 TC88 with Andrews 21's. Note the torque is there already at 2200 RPM's.

I had 26's in my '07 and liked them. I can't remember what Andrews said as far as when they were supposed to start making power but I couldn't really feel much difference until I hit about 2700 rpm's, at which point I liked them alot. I'm leaning toward 255's or 21's on my new bike.

Got the 21's in my 88 incher. you can feel it kick in at about 1600 RPMs. Don't know when it falls off, I'm a conservative rider. She pulls hard to around 3K when I shift, and I'm sure it will go much further. Not a monstrous amount of torque, but strong and solid all the way. Great for two up. Me and mama weigh in at around 420, so it really helps us get down the road. 26's might be a better bet for your 96 incher. Will work better if you want to upgrade the displacement and compression later. BTW the 21's have a lift of .498. I believe stock Harleys need to stay under .500.
