Using SERT 2010. Has anyone been able to get these pipes tuned properly for good low end torque or great torque & hp? Dyno says 86hp &96t should be 100 & 111 at least.

 

what cams? I have never seen an AMS build that makes 111 ft/lbs most do under 100 just like yours.

 

CAM andrews 54w, big gulp air V&H 2into1 HO

 

i'm using the v&h 2 into 1 and it tuned great on my 10.75 compression ratio 103" motor. the guy with the dyno, did he tune it for you, or just do a dyno run to see what it was putting out? if it's not been dialed in-tuned properly by someone who's really familiar with harleys, then that's likely the problem with having such low numbers. i must also mention that it's a bit optomistic to expect the 100/111 for that build, in my opinion. the 100/104 is way more than i need, and with proper tuning you should be able to match or beat those numbers by a bit. it depends on a lot.

 

Most AMS builds are pretty low compression and unless you specified higher compression that is what you got. My buddy tried to get his heads set up so he had 9.8 to 1 and AMS would not do it (this was a few years ago on a 96" build with andrews 37's). I think your numbers are in the ball park depending on the dyno.
