Bike is a 2003 FLSTF that I bumped up to a 95ci about 15,000 miles ago. Since the build, its been a great runner and overall I have been pleased with how it runs. Im getting the itch to do a cam swap to see how the bike would respond, im currently running Andrews TW37 cams. Im running a set of 06+ heads ported and polished with a .030 head gasket, SE domed pistons, DTT ignition module, 3.37 gearing. Compression is around 10.5:1(educated guess) Compression test readings are 200psi front and rear.
Had the heads milled to 85cc combustion chamber volume, compression releases put in. Stock sized valves and a street port job basically.

I'm still running the old spring loaded tensioner and cam plate, which i'm sticking with. So that somewhat limits what my choices are as not many companies are still making cams for the old setup from what I can tell. Perhaps I'm wrong on this.

Looking for low end/midrange torque and a set of cams that will better utilize the compression, headwork and beehive springs ive got. Current HP and TQ numbers are 85hp and 102tq. Torque is 100 @ 3k to 3.5k rpm, a rather short window and drops steep after that point. Anything out there that will hold the torque a little longer? Was looking into the TW54 by andrews?

Thanks guys

 

have you looked at the 585s from S&S? If I remember right those were nice low end grunts from basically idle to 5500 or so.

 

You may not have optimal compression to run S&S 585. Look into something with a similar IVC event to keep your CCP up around 200 psi and take advantage of the lift available to you. Maybe S&S 570, Andrews 57, etc.

 

i am running the tw54 cams, you will not get more out of your set up (much more), unless you have the heads truly worked over. with the stock 04 heads(casting clean up, black diamond stock size valves and hi lift S&S springs, the best it would do on the dyno (i am the operator/tuner) was 91/98. I pulled the heads, didnt change anything else and installed a set of 06 later heads that had Kirby's street port w/ larger valves. the numbers went up 104/109. the 37's are a pretty good cam, but i think you are having more headflow issues than anything else. can you post up your graphs from you dyno session. the other question to ask is what exhaust system are you using. my previous statements are based on the use of one of the tried and true good quality systems.

Exhaust is a cobra power pro 2 into 1. Not my favorite pipe ive ever run. These exhaust companies want too much $$ for their pipes. So I run a Cobra, I cant afford another pipe so its gotta stay.

As far as tuning, Since that dyno run i posted the numbers of ive done some seat of the pants tuning on the twin tec and messing with the carb jetting if feels like it runs stronger now. I just havent had another dyno run,

 

 

A better cam is not going to fix a funky exhaust..

 

Well then, I have a gen one Dragula, used only one season and it compared favorably to a Fat Cat, both pipes tuned by a world reknowned tuner.

 

if your looking for low end TQ,the 585 isn't for you,its a higher RPM cam.a V&H pro pipe would work very well with the build you have,no reason to overkill it .if you are running 10.5-1,thats a lot of compression for the 37 cam.i would try to first verify what compression you really have & choose a cam from there.your probably closer to 10.1-10.2-1,even there,your build should be doing a lot more than it is,(100+/110)ide try a new pipe & get the heads checked/worked some more
