I posted this in the Dyna section, but thought I'd throw it our here for those that don't necessarily have Dynas or frequent the Dyna forum.
This was a 103" to 110" Stage 4 build and tune. Work done by Sheffer Performance in Indiana. CR machined heads, Bassani RR2 Short pipe (impacted my low end a little but still love the look). HPI 58 TB with larger injectors. Quite the change from my Stage 1 upgrades! Needless to say I'm pleased.
For those with bigger bikes and longer pipes, I've seen dyno charts of this build with another 10+ ft-lbs of torque 2000-3000 erpm with no appreciable fall off on the RH side.
Actually, I think it's really more the effect of short pipe than the cam. I already had the RR2 for tall shocks which is really short and doesn't tune well down low with this cam. I spent the money on the build knowing I could go to an exhaust more fitted for the build in the future.
I have charts of this same build, full length pipe like a Boarzilla or Mellow with the CR595 making 100@2000 and 110@2500. I just didn't have the $'s left to go for a new pipe at this time.

Bet Larry's heads had something to do with this,, The stock decated head pipes are are pretty short also this the mellows helped. I added a extension to the short Bassani on 116 dyna and it helped tho I've not been to a Dyno.
