Put new d&d 2:1 M8 billet exhaust on. No change in dyno numbers compared to original CVO 114" exhaust. What's up?!!!
At this level the cam is the choke point. That's what we've seen with our Milwaukee Eight 107" test mule.
I have tested this with several different mufflers, de-catted head pipe, ect. If a guy is only going to do a stage one, be sure to include a good air cleaner, that's what gave ours the biggest gains at this level, as the stock filter element would barely be big enough for a lawn tractor.
We are working along side Wes Brown @ Cycle-Rama on cam development, and it's coming along nicely. I have one more exhaust to test with the current prototype cam in the bike, and a new grind on the table to go in with a complete round of exhaust testing.
These cams have the stock base circle for the guys that like to re-use stock push rods.
For anyone interested, our test results from bone stock, to where we are now, can be viewed on our Facebook page.
