RE: High Flow Air Cleaners
I'm going to call them in the morning to see if they could have it here by Wednesday, I need it installed for my dyno tuning Thursday.
If that doesn't work out, then I'll go with the Zipper's upgrade filter. For $62 and they are in MD so it would be here in a couple of days.

Yes, I am very interested in that air filter also. That looks awesome, and would be the last filter I would ever have to buy at 800+ cfm.

You could go ahead and do your dyno run with no filter then add the Overflow and it will not change your numbers considering your engine will not require the high flow abilities that this filter gives. It is worth the wait to use the Overflow model, it is well made.

Try the Kuryaken "hyperchargers" I put the Pro R on my 05 Dyna and couldn't believe the throttle response. The thing would just get up and go. I am now going to put one on my 07 Ultra with a wildthings tuner and Rineharts. I bet this thing will come alive.

One of the magazines had an article this month on the flow rate of most of the popular set-ups. Zippers had the best flow rate of them all.

Woods makes one that does 340 cfm, and the BC Overflow does 800+ cfm.

I run the Woods 325 filter that flows 340cfm, it will work with the Harley back plate, it will not fit under the football style cover. If you would like some pics let me know.

RE: High Flow Air Cleaners
I ended up going with the Zipper's upgrade filter - 321 cfm.
I like how it's still a tapered filter and I can use my Skull endcap with it still.
Should be here tomorrow and I'll have it on and ready for the dyno on Thursday.

At what point would an air cleaner allow TOO much air though, and require a larger fuel injector? I would think eventually that threshold would be hit; too large of an A/C would make the bike too lean, once the injector hits it's max point for output.
