Devin and I spent yesterday & today with Jack and his M8 Freewheeler.
We fitted quite a few variations of prototype Stage I Air Cleaners we've been working on. Then I spent some time riding it stock, gathering temperature data.
Today I rode it a bit more, gathering some more temperature data.
Then we spent 6 hours on the dyno, we did 49 pulls.
We tested 5 different Stage I Air Cleaner set-ups.
We tested 6 different tunes, both at WOT and at cruising.
Next week we will fully analyze the data and be posting some overlay charts.
I was expecting a lot out of the M8 power-plant.
From my previous couple of rides, plus looking at it on paper, I believed there was a lot of untapped potential, even in just a Stage I upgrade.
It exceeded my expectations! The increase in usable, everyday riding, power was surprising.
Here's a photo of Jack & Devin right before he started back home. He's riding home with a Stage I Air Cleaner, a Power Vision tune and a bunch more power!
Thank you Jack! Enjoyed our time together.

P.S. I am not even allowed to post the following information on another forum...it upsets too many vendors. lol
Today, the Myth that the new HD air cleaners are somehow "Stage I" (ie. flow all the air needed) was ground into fine powder.
On the very first DK Stage I air cleaner we tested, WITHOUT even changing the factory tune, it produced an 11.94% increase in power!
