Had a little time today to post this info that I have been wanting to for awhile.
First graph shows the power of two Vaquero's and a 2012 Street Glide we just did a few weeks ago. All engines are 1700cc. The Vulcans's have the Big 3, slip-ons, BAK and PCV. The blue run has V&H s/ons & a Thunder round BAK, the red run has Cobra s/ons and a Chuckster BAK.
The Street Glide has a PM/RSD BAK, a complete True Dual Exhaust and the PCV and is the green run.
This graph shows the advantage engines with four valve heads have over engines with two-valve heads.
The vertical black line is a floating cursor that is displaying power at 3000rpm so you can see the difference there. Peak power for the blue Vaq is 81.74, the red Vaq is 80.83 and the S/G is 77.36 H.P.
Here is the torque graph for the same skoots...
Peak torque for the blue Vaq is 100.8, 98.59 for the red Vaq and 94.08 for the S/G.
