Thanks. I will be getting the map from the tuner, but for all of the "power" positions he started at 13.0. For the "cruising" positions we didn't exceed 14.1. I could have gone leaner, but heat (engine longevity) and power were my primary requests of the tuner. He suspects that I will be getting 38-40 mpg and down from there depending on how much I'm getting on it.

By the way, I tuned it only on 91 premium. I'm looking forward to seeing how she runs the river valley tomorrow on 110 racing fuel. [sm=icon_rock.gif]

 

are the heads stock SE's or were they ported?
are they the cnc ones or the other pair?
numbers look good....very envious

 

impressive torque curve, no real dips. congrats

 

All stock SE stuff (almost). I wanted to do a build this way.

I'm running the following:
SE Stage I - with Zippers high-flow kit
V&H ProPipes
95" with SE flat-top pistons (10:1 compression)
SE-251 cam
SE Performance Heads - Stock (not HTCC) with compression releases (just because they are cool)
SE lifters, roller rocker arms, perfect fit push rods, engine studs, head gasket
SE clutch kit (not just the spring)
S&S Crankcase Breather Valve per recommendation of St. Paul HD.

Build design - me (and all you out there who helped)
Builder - St. Paul HD
Dyno - Jason at Faribault HD

 

thanks
i was lookin at those heads cause of the price but i didnt know if they would give me the numbers i was after.
sure likes like they will

 

A big thing with this build (and any build for that matter) is matching up components. I have received feedback on the heads that running flat-top pistons will provide the best combustion chamber with these heads. With a 10:1 compression ratio, which is relatively low for a hot-rod, you need a higher lift, shorter duration cam since you don't have the extra compression boost. This is why I did the SE-251 cam. Also, as with any build stiffening things up, improving oil flow, and reducing friction points will all help as you have less power lost to heat. This is why on this "mild" build I did lifters, engine studs, roller rockers, and the "secret" trick of an S&S breather valve.

I'm obviously a Harley/Screamin' Eagle fan, and with these results, rightfully so. Don't get me wrong, there are a lot of **great** aftermarket hot-rod parts as well, many of which I considered. Feel free to let me know if you have any further questions.

 

Nice curve on the HP and TQ looks like you have got a nice wide power band and pulling hard through all the RPM Nice Job

 

Are you sure? I'd have thought that the white and silver would be slower because they have to push all that light out of the way that the black just absorbs

 

congrats on your build....numbers look good... i can't wait till i get back off the boat to finish up my breakin.. only 400 miles on mine right now
