This morning I stopped by my buddies shop to see what numbers my 2011 CVO Street Glide would make with V & H Dresser Duals, Hi-Output Slipons and a Powercommander V. PLus I wanted to see if he could cool it down a bit.
He made one run, tweeked it and ran another. It was 96 degrees, barmetric pressure about 28 in-Hg and the humidity around 28%.
I was surprised to see the peak TQ at 108.25 (3700 RPM) since I've always heard free flowing pipes and true duals really hurt the TQ numbers. 100.87 TQ at 2700 rpm to 101.10 at 4600 rpm. My other surprise was that the peak HP number was only 89.52.
All the dyno charts I've seen with 2-1-2 headers, less restricive mufflers and different tuner mods range around 102 TQ and 95 HP.
Once I get the chart I'll post it but the curves are pretty smooth.
Thoughts?
