Screamin Eagle 585 Cam Concerns
Fergot to mention that the Screamin Eagle Forged Flat-Top Stroker Pistons(+.010) P/N 22942-00A at 10:1, had the skirts coated by Calico Coatings.
I'm not sure I like how it feels above 4.5 grand though, think I need more timing up there...loaded it up and took a trip to SC this last weekend with the wife and a few hundred pounds (Dont ask, figure it out) and it felt almost as strong as riding alone before the mods. I do believe the 55mm TB is what gave me the 100+ hp. I can shift at 3 grand and move out smartly and at 4 to really get down and since 80mph is at 3 grand cruising from 75-85 fully loaded is eazy-peazy, even up inclines.
And I do like the extra oil pressure at highway speeds...
1. I didn't gaff of any recommendations, I had 90% of the parts before I started the post. I was a Mustang 5.0 guy in a previous life and high output oil pumps and roller rockers are in my blood...I may change out the roller rockers but i enjoy the higher oil pressure.
2. This build was based on conversation I had with those on this forum and I have a companion post to this one over on HD Forums under the same title. I was determined to see it through, and I did.
3. I am more than sure that there is some more left in her but this weekend on a trip to Paris Island SC I was knocking down mpg in the 40+ range with wife and a few hundred extra pounds (figure it out) averaging 67 mph over a 260 mile distance one way according to the GPS with 90 mph peaks. When solo and without a few hundred extra pounds I keep trying to find 7th gear.
4. I bleeve Thundermax is in the future for this bike, so long as "ALL" of my accessories work as they do now.
5. In the Marine Corps we have a saying "Don't fall in love with the plan." in other words I may do something different eventually.
6. I believe that the HPI Throttle Body is the reason that my hp is as high as it is with the torque band as wide as it is. The Tech made mention of 58 mm TBs sometimes take a lot to get a smooth idle and he said mine was good. Also too, I wanted the 4.9 injectors like what are supposed to be in the stage 4 but its a misprint as the stage 4 uses the 5.3 injectors; totally different connector, which I had installed. Also a shout out to HPI who, in spite of my "hurry up, I've got to get this done attitude", helped me pick the right size and shipped it almost overnight over that "middle of the week" 4th of July we had, VERY helpful.
7. I'm not worried as much about peak hp, more concerned about drivability, "get out of the way ability" fuel economy and the ability to traverse this country during the summer using the fuel available with minimum used of additives, especially with passenger and a few extra hundred pounds.
Respectfully submitted.
