Ride report; {Reposted from another discussion (getting your torque back) as it applies to the Roll-on Comparisons}.
Me and texas.devops went to Mexico yesterday and did some Roll-on Test's.
After Steve came up with the idea for a restrictor in a Delk or Black Widow system, I decided to do this on a dual muffler system to see if the reducer idea would do anything. I wasn't sure, and Steve wondered too.
(Quick answer. It does, and can be used to tune your torque curve). See below.
,,With no restrictor's, the bikes were basically even with neither pulling away at low/mid rpm's. (bike seemed a little abrupt at lower throttle openings)
,,With 2 restrictor's, his bike pulled away slightly at low/mid rpm's. (bike seemed to hesitate at lower throttle openings)
,,With 1 restrictor, my bike now pull's away slightly at low/mid rpm's. (bike feels really smooth at lower throttle openings)
NOTE: Texas and I have 2 bikes that are very close to one another in performance. At high RPM's their even.
ie; (The restrictors changed high RPM power very little. (If at all)
Because of the Roll on comparison, and because we have such closely matched bikes, we are able to "see" what is happening.
If you don't have another (closely powered) bike to compare with, it all comes down to your Butt Dyno and Butt Dyno's lie!
That said: A Butt Dyno does tell you differences.....
When I installed 2 restrictors, I could feel that something wasn't right. Removing 1 of the restrictor's, the feel was noticeably better.
NOTE: I'm NOT talking about WOT. I'm talking about partial throttle/low RPM torque.
Ride safe, Ted
