just wanted to let you know put one of those new Doherty Machine powerpaccs on my 08 street glide wow what a nice piece good quality and what a difference in horsepower

 

They are a very nice piece of work, best looking backing plate on the market.

I've had 2-3 other air cleaner kits, and the Doherty is by far the highest quality.

I am just about to pull the trigger on one myself. Glad to hear you are impressed with it.

 

I agree with Steve, the Dohertys are a piece of art comparred to the others.

 

Has anyone used the PowerPACC with basic Vance & Hines slipons? If so, what FI controller did you use and were you ale to get a reliable map for it without having to spend the $$ to put it on the Dyno? I have a stock 2009 Ultra Classic with no other mods. Thanks much.

 

I've been running one for a few years.

Nice piece of machine work. I have never seen a better set-up.
I modified my Zippers A/C to fit it (only a matter of bolt holes and riser bolt length).

I strongly recommend this backing plate.

 

So, what is the difference in horsepower?

Welcome to the forum.

 

Top knotch stuff man. Love the velocity stack that snaps onto the plate. And don't forget to get the kit with the breather vents.

 

How do these work with 08-up. Their site says power vents do not work with TBW models. How is the blow by routed?

 

PM sent. Pics to follow.
