I have the Andrews 26G cams with S&S gear drive, absolutely happy with the setup tuned with carb (dynojet kit), Vance and Hines duals with Screaming Eagle pipes.

 

Most are happy with the 26s in a stock set up as there should be a good seat of the pants increase in pulling power. My preferences are the HQ 0034 and the Woods TW6. Two into one on a stock engine robs a bit of torque, but not enough that you should run right out and buy a two into one. Headwork is where the torque and HP is. Witht he 26s, you can make it sing with a little head improvement. Someone mentioned the HD 230s, again not the best but are similar to the 26's.

Tuning might also be a bit off, you should be getting 40+mpg, but to build torque, it does need to be a bit richer in the throttle positions that you would normally use for pulling or acceleration.

 

Have found out the hard way, the 26G's DON't like head work. If you are not going with head work, should be fine. Otherwise, TW6 a better choice. I've had my apart twice trying to tweak things to get the 26g's to work with my head work - pings when real hot.

 

The TW26 will hurt low-end TQ considerably, based on this snippet from two dyno charts, one with a Fuel Moto Power Package (otherwise stock bike) and the other a TW26 with typical Stage 1 upgrades (AC and muffler). The TW26 TQ does surpass the stock cam but only after about 4000 RPM. Below that the TW26 is producing much less TQ that you could use for passing a truck in 5th gear, although it will produce more HP if that is your fetish. Personally, HP is secondary and not worth an increase if it decreases low-end TQ.

More duration means lower low-end TQ, which can be regained to some degree by increasing compression, which is more invasive and expensive. In addition, it may create problems with detonation.

I'm waiting for someone to dyno a TC96 with a TW21 installed.

 

I love my Andrews 26g cams! It was one of the best upgrades I made to my bike. The cam coupled with a good 2X1 pipe will give you great low end pull. Be ready to sacrifice gas milage over 70 mph however.

 

Having put TW26 cams in a bagger I would recommend you not waste the money. I had my bike dyno tuned and while the TW26 cams did make slightly more power it just wasnt worth the expense in my opinion. Even though I did the work my self it still costs a lot considering the cams, pushrods, gaskets and dyno tuning. And you have to have the dyno tuning. Some people said a mild cam change would not affect the tuning much. In my case that was wrong. It took a lot more added fuel than I would have expected to get the bike back to a proper state of tune. Just my opinon, but its a lot of work and money for 2 or 3 more hp and ft lbs. which was all I got. Obviously other people may have had different results.

I now have the 26H's installed in my stock top end, 07 Heritage. The Andrews 26H cams did just the opposite as you stated.
Also while studying cams prior to choosing mine all the articles that I have read stated that lower duration 220-235 produce good LOW-MID range tq, and 235-250 give good MID-HIGH tq. over 260 gives UPPER tq, so this is another reason why I choose the 26's.
Also the intake closing of 35* plus the LSA of 104 and the LC of 102/106 is what makes this little bolt in cam a really good performer in the low and mid rpm's.

In the thumbnails below I have the base run,
Then I compared stock to the stage1 + 26's, I drew in the red line to get both on one sheet, they were done at different shops,
The final dyno sheets to show the number are correct.
I posted them in the softail section, under the sticky thread, (dynos for softails)....

I am totally pleased with the cams, 12-25% gain over stock across the board and the sheets show it...

I dont know what fuel moto did to get the #'s on there dyno sheet, but what I got was completely different, with stock headers and rush 2" slip ons I feel these are decent, not great #'s. Its not a race machine, but 80/91 is fun to ride and gives Grandma and Me about as much as we/I want.. plus I got rid of that EPA stock cam.....
And it does have a little lope to it. Makes the 96 sound better.

 

The 26's in my '07 Ultra were a BIG improvement in low and mid-range torque. Not sure how much difference it makes that mine is a 96" and that I have a 2 into1 pipe and T-Max, but it runs really well and WAS money well spent.

 

Well I have an 07 ultra with rinehart TD, seac and sert, tommorrow will be installing the s&s gear drive and andrews 26 and getting it retuned. I will try to post the dyno # after it is done

 

just wondering, why the change to gears on the cams with the improvement made on the tensioners not an issue anymore and the crank run out is now more of one?
