Thats awesome! If you get that data would you mind posting it up? Or at least a general % difference you found. Pretty please with a cherry on top

Yes sir, I have it still sitting in the box in the bag it comes in. My engine is out of my bike right now with the head getting some work done to it but hope to have it all back together by the end of April. Once I make it to the track I'll post some time slips from the drag strip to show any difference between the MWR WSBK filter and my BMC Race filter I currently have.

Plan to dyno it too but might wait until mid summer when its back to stock wheel base so the numbers look higher than with the 12" stretch on it lol.

I'm planning on doing some standing half mile racing in September and depending how the drag strip testing and dyno goes I'd like to try swapping filters there too as I feel like that'd be where the filter would really shine.

But do plan on posting up some slips and dyno numbers in this thread!

Just a heads up, you're not likely to see much of anything on the dyno. It's designed to work at speed. So static dyno = no pressurized intake/airbox = filter isn't working in the conditions it was designed for. You may gain a little something from the differences between the flow rates between the MWR and BMC though.

But you'll definitely see it and notice it at the track as the one guy earlier he said he picked up 5 MPH from it. (I'm not a drag racer so I don't know if that's a huge gain or not haha). At speed I noted a 3-5% hit to my AFR depending on RPM/load/gear while data logging so I figured since that was the only thing I changed, it must be the reason.

That's kind of what I've heard is that on the dyno it doesn't always show much for gains but in the real world on the street and track is where it really shines. Why I'm not in a huge rush to throw it on the dyno compared to getting out on the track and do back to back testing. Might try to do some 9/10th's gps runs in Mexico this summer once its back to swb and want to try swapping out filters when I do those tests as well as I'd thinking this filter should give me a bit more mph during that too.

5 mph is huge in the quarter for just doing an air filter! If I can get those kind of gains, I bet all my buddies have these filters by year end lol

I love those filters, but you have to tune to them via trim tables, they just lean the bike, when you hit 6th, and start leaving the s1000rr behind.

The gains i saw were from doing the filter and gutting the ram air at the same time. Either way 4-5mph is HUGE. And I've seen it consistently

Are these gen4s or gen5s I really wish I waited the extra 4days to get this. I'm running a DNA filter at the moment.

Any luck on doing that testing? If so, would you be willing to share your info for the masses?

Hope to get my bike up and running in a few weeks and it'd be sweet to know what kind of results you saw as you're the only one I know that was doing such a great test!
