DNA vs BMC vs Pipercross

[Lycan]

There has actually been several threads "trying" to discuss which filter is best, but weirdly, nobody that actually knows will chime in.  I'm pretty sure that the several board sponsors that post dyno results have done time with different filter, but seem not to want to touch this subject. Hmmmm

Ryan Schintz has a dyno comparison of a BMC Race vs Pipercross vs stock on his site. The BMC Race makes the most power.....and gives the best throttle response  

If you have a pre-mapped 2008 Hayabusa and want to compare the three filters let me know. The Pipercross RACE needs to be on a mapped bike it flows that much, I call it a tuners filter. We have a ram air simulation set-up here with a 17 to 1 air exchange per minute in our dyno room and the Pipercross is tough to beat anywhere in the RPM range.

Just need one bike, we have the three filters here and its not just because we sell the Pipercross. Just call me and let me know when your comining up and we will post the results here, the room stays the same temperature all day with the climate control so apples to apples is pretty simple. We will run the bike at the same engine temp for each test as well. Free filter for the test mule. Should be done in an hour.

Hey Greg, you want me to bring my 08 up? LMK can probably do Friday

BTW I also need an oil change and 1st service while ya got it!

I ran the PiperCross filter today, last week I ran no filter, it mph the same in the 1/8th mile, must flow well,  you have the saftey of a filter to catch stuff. I cant speak for the BMC or DNA, but if the mph is the same as no filter it must be good. Thanks HPC for the filter


wee

Good news Wheelie thats my point with the RACE spec filter. It flows.....

Speaks well for airbox design too... on motors with carbs, we found that the air filters would help by "cleaning" up the air flow, not just the air (non airbox motors).. turbulent flow would "stifle" the motor at certain RPMS/MPH...

Greg, does this show up on the dyno as well or is it strictly related to the MPH issue?

 

[Lycan]

Ok gang it seems Greg will be running the filters on my 08 this Friday, stay tuned for the results, we all know Greg can be trusted to give us the real picture of things so this should clear it up for everybody

besides, I'm off Friday so what better way to spend it than riding to see one of our sponsors

The Pipercross makes more power on the dyno VS. the stock filter. The Pipercross also shows better gains with ram air added over the stock filter as well.  

No better test than MPH with a consistant rider like Wheelie.

 

[Mr Bogus]

cool....

Hey Greg, I know you are not into "shameless" self promotion but you should post your banner in you signature... (it has the phone number!) or at least put the phone number there..

Just nice to have as a "trusted" sponsor of the site. You are not alone in that respect but it is a great getting advice and service from a person without all the "bias" Thanks again!

(well maybe a bit of bias, you seem to dump junk that does not work and keep the "good" stuff on hand)

EDIT: that was fast

now if I can get you off dyno for a few minutes

Please somebody tell me what filter to buy for the street!
Please take my money and sell me a filter somebody!

The one that makes the most power that is

From all the info i have received as long as you clean your filter put in the best, pipercross race just take care of it. I ordered mine from greg this weekend and cant wait to put on and dyno. Im new to bikes but on cars you can put on high flowing filters and do race modifications and use it as a daily driver, the problem comes when people modify there vehicles and dont keep them up , the more you modify the more you need to service them, but if you love speed its worth it just my 2cents

 

[Wheelie]

The one that makes the most power that is

if you only street ride, I would suggest the Pipecross Street version, or if you get another filter, make sure its the street filter. Anything but a K@N.

O.K. Greg..... since I started this thread, is there any chance of me getting a discount or even a free filter?

 

[bigmike32172]

I need to find a vendor that wants to sell me a pipercross street filter for an 08

Sounds like the one I'll get too after the stocker runs its course.

I'm calling tomorrow.
Thanx!

 

[Lycan]

Ok leaving to see Greg, I guess we will check in later!

hot as hell today, humid but hey it's a ride!

 

[ArkGL01]

Just ordered one off the web site

I scarfed up a Pipercross from Greg several months ago after his initial R-77 testing... any sponsor who hooks up the community with free vital info should definitely be patronized. I *might* have found a cut-throat price from some "blow-out" vendor, but it's good for karma points to support those who support us!

I waited to the first spark plug change to drop in the Pipercross:

The OEM filter has an impressive wire-mesh screen that the Pipercross does not (which certainly doesn't mean the paper OEM filter is "better"; I'm just remarking on the difference in construction). It is apparent the OEM filter does a fine job itself: there is a substantial amount of fine dust that I ride through here in the High Desert, yet the airbox interior looks clean enough to eat off of:

Below is the business end of the OEM paper filter. I changed this a little earlier than the Schedule Maintenance interval calls for... this filter only has 8400 miles on it:

After installing the Papercross, did I feel/notice the extra 1-2 hp?

Um, no.

And I didn't expect to.... I got the Pipercross for the maintenance longevity, so I don't have to buy paper filters 3 times a year.
