I recently upgraded my 2011 streetbob's 96" motor. I got a screaming deal on a stage 2 103" upgrade kit and had it installed. I was previously running and kept HD Heavy breather & SERT with V&H big radius 2-2 exhaust. I've only put 100 miles on the new set up so far and it was dyno'd with gas that had been sitting through the winter but just out of curiosity where do I go next to make 100+HP/TQ?

 

Head work will take you there and beyond.

 

I took my 88 TC to 95 inch, 10.25 to 1 domed pistions, .574 Fueling cams, Fueling roller lifters, HD Heavy Breather, BCT Baffles, HD Super Tuner....I the biggest deal was the heads.

Ported, polished 10 thousandth over valves, High Comp springs.

I haven't had it Dyno'ed yet but the tech who put it together was pretty impressed after last winters test ride and camed it should be an easy 105 HP plus.

I'd say cams and head work.

 

You could also try gettin rid of those candy *** pipes.

 

I agree with cams and head work

 

Cams, head work, TB, AND 2 into 1 pipes. You are leaving a bunch on the table with any 2-2 pipes.

I agree 100% with HYPR

 

Anyone here will tell you if you are going for performance, its gotta start with a decent 2-1 pipe. Lots of threads to help you pick one. Good luck.

 

The stage 2 103" comes with cams. SE255's are already in it. Also it's the flat dish pistons not the forged high compression ones. I thought about switching to a thunderheader but talk of a torque dip kinda worried me. I'm trying to find more info on that. The D&D Bobcat has also peaked my interest. I wanna keep my power down low. I don't typically ride above 4.5k
