Hello all. Sorry if I'm messing something up with this. I normally just read. I'm looking for any other thoughts/ideas, or comments on my idea, for pulling a little more top end out of this build without loosing to much in the bottom. 2007 FLHTCU, recently built to 110” with a 48mm TB (Johnson Engine Technology) and 3.9 gm/sec injectors. Road Rage pipe (I love this pipe), high flow intake, Andrews 50 cams, tuned with Direct Link. I believe that the port floors were raised to increase velocity. (It was built from 96", Dresser Duels, TW48 cam, 4.9 gm/sec injectors, Daytona Twin Tech TCFI 4)The dyno graph (attached) shows more than 110 TQ from 2500 to 5000 but dives from there. Most of my riding is 3000 rpm or less. This thing has incredible pull (in my opinion) out to 4000 or 5000 rpm (gear dependent) but I can’t pull more than about 4500 rpm in 5th or 4000 in 6th. Tops out at 109 mph (the stock 96 once hit 112 mph). Worst of all, my sons factory 107 pulled away on a hill and he never knew I was trying! I'm thinking about a little more air (Jim's 53mm elliptical), and 4.9 injectors. The bike has 100,000+ miles but only 5 to 6000 on this build and I intend to run it at least another 100,000. Again, any thoughts, ideas, or comments would be appreciated. Oh, by the way, I also did the crash bar oil cooler. Way worth it. This build was HOT well over 230 in just a few minutes riding. I dropped 20 -30 deg. with the crash bar and it takes much longer to heat up. Ride through a rain and the oil temp will drop from 230 to 180 in 5 miles.
