The question of dyno numbers comes up every so often, so I wanted to post my buddies numbers. He recently sold his Twinkie Heritage in lieu of a lighter, more agile Dyna Convertible. The bike is a 1997 80 inch Evo with a stage one. His parts list is as follows:
It has screamin' eagle II pipes and a V&H air cleaner with a K&N style filter. The V&H air cleaner has a small velocity stack in it to improve air flow, and new plugs & wires.
Peak torque was 87.9 at 3300 RPM peak HP was 66.7 at 4300 RPM.
Just wanted to share. I was pretty impressed with his torque figures, especially given the Twinkie guys routinely insist that 2 into ones and only 2:1 exhaust systems make torque.
