I am installing the Kurykyn/Thunder Manf. hypercharger and vance and hines cut and staggers on my 07 vulcan 900 classic i am curious as to how much this ups my performance...anyone got the specs i cant find them?


HP,Torque??  

I hope that you're going to also install a fuel processor.  The new intake is going to lean out your engine and some adjustments will need to be made.  On another forum, a rider posted his dyno readings before/after adding a set of Roadhouse 2-1 pipes, Cobra Fi2000R processor, and a Baron BAK intake.  End result was an increase of 23 HP!  

You might want to check out the forums at VROC.org, the Vulcan Owners & Riders Club website. They are a fairly large group of people from all walks of life and I wouldn't be surprised to find someone there has all the specs, including dyno results, for what you are wanting to do.
