Default 204 cam Dyno performance report

Just a short note, finally got done with the 2008 Dyna Street Bob upgrade done.

Now has a H.D. S.E. 204 cam
Bored to yield 103 cu. in, no stroke change.
Kept compression at 9.5
Hammer Performance basic Impact porting
Heavy breather
V&Hines short shots.
Nothing else done.

yielded 109 ft. lbs. torque
94 H.P.

Very nice and roadable, runs will all the way up with good torque.

Thought you might like to know.

Couldn't find a good base map with the 204 in the S.E. Pro tuner tables that also had 103 cu in so had to use a different torque cam base setting that also had 103 cu. in. but it worked out fine.

regards

Paul

Mind if I ask who did it and where they are? I'm just across the yard and am thinking about doing the same.

Good numbers Paul. I did the similar thing this past spring and the numbers are in my sig. I went with new pistons and 10 to 1 compression.
