Bubba_T's motor is done. The dyno sheet is 116 Ftlbs of Torque and 110 HP. The TQ comes on at about 2500 RPM's and peaks at about 3750 continuing on a mostly flat line to 5,200 where as with all motors it drops off. the HP peaks at just about redline or 6,200. This motor has CVO 103 heads ported and polished by Dave Mackie. 103 cylinders with Mackie's custom machined semi-domed pistons running about 10.5 / 1 compression. Mackie DM598G cams. Fueling oil pump, lifters, cylinder studs. SE Adjustable pushrods. S&S gear drive kit and all eutectic gaskets. A stock throttle body was bored out to 49mm by BC Gerolami and it is running a Gerolamy air cleaner on a Screamin Eagle breather. Bassani True-dual headpipes and mufflers. All wrapped up with a Power Commander.I was extremely skeptical of the dyno numbers after riding it This bike is VERY IMPRESSIVE to ride. It is smooth from idle to WFO and at 3200 it takes off like it's hooked up with nitros. While it wouldn't beat my 05 SEVROD, it is fast - - - damn fast. The dyno run on the sheet is listed as #6 of some 20 runs made. Bubba wanted the bike back and who knows what the dyno shop gave him for paperwork. C'est la vie, as I've said before dyno sheets are for sitting in bars and running your mouth beyond what the tell the tuner. This bike runs STRONG, very strong. My 103 is 108TQ an 103-104HP and there's no way I'm gonna be within a 100 yds of Bubba stop light to stop light. Cost to take Bubba_T's stock 03 SERK and turn into what he has now was not cheap. $6k total. Is it worth it ? Absolutely. I spent very close to this on my 103 build trying to use all H-D parts to keep my warranty intact. (so I was told at the time) My warranty as noted on another thread is now void and I don't have anywhere near what Bubba's got for a motor, so yeah, if I had it to do over , for sure I'd go this route. Twolane has a very similar Dave Mackie set-up with a bit more displacement, bigger heads, a two into one system and a bigger throttle body. He's in the upper 120's somewhere on both numbers.
Now before 100 people post how so and so and such and such parts produce way more this and that, let me say this. Dave Mackie and I have worked together on several Hi-Po motors I've had in bikes. One, built in 1995 is still out on the street with only a fresh valve job after about 20,000 hard miles. Another is in a chopper somewhere running strong after who knows how many miles. And that's the bottom line with Dave Mackie Engineering. Good solid perforamance for the street and rock solid reliability. Can't beat that
