Guinea pig wanted for intake modifications

We've got a new filter setup on the way for the M696/796/1100. It allows the absolute most airflow from the standard airbox. It is a combination of the already existing top filter (circular) and the soon to be released supplemental filter (with red anodized aluminum frame in image). Anyhow, if someone is planning a run to the dyno soon and has the ability to tune their bike I'll send you a free set of both filters if you do a before/after run.

Before = original intake, FI tuned for best results.
After = MWR intake, FI tuned for best results.

 I wish this had been out a couple of days ago, Not that I like being the guinea pig for anything but I would have volunteered my 796 for this- As it sits now, it is in the process of being moved and I am soon to follow it out to Colorado. BTW, what will the proposed/Ballpark going price of this setup if it works out.

Good luck on the move to CO - great state!

The first part of the kit is $115 and is here: http://www.mota-lab.com/mwr-ducati-monster-6967961100-air-filter-kit-p-392.html

The second part doesn't have a definite price yet (will early next week), but around $70.

I'm planning on getting the first part of this kit before I bring my m1100s in for service. I had my bike dynoed in stock form (except cored pipes). But since then I've put a full exhaust, dp filter + air box, and flashed ecu. I've got dyno numbers for each mod ( but not tuned).
I'd love to test it out, but my new service guy doesn't have a dyno. And I'm not going back to my old shop. [thumbsdown]

Voice inflection does not come across as desired in a post so let me say this up front; I am NOT flaming but rather asking a question I don't know the answer to.

Why would one do this as opposed to velocity stacks? If they both require a dyno tune why not eliminate the airbox all together?

Does this option offer you increased air flow while maintaining the features of an air filter?

It's a fair question.

The theory (although I'd say it's reality) is that while pods / velo stacks may 'flow' more air than an airbox, an airbox works better because it's drawing air into the intakes from a source of still, non-turbulent air.

You'll notice modern racers don't run pods, they run giant airboxes.

So "really well breathing airbox > Pods / velo stacks'

You are absolutely right on this account and it never crossed my mind before you said it!

AND it's the same thing I've been saying all along. The pods are great for the dyno, but at speed... no way they can draw in more air as they don't have the sucking power to overcome 100+ mph disturbed air flowing past them.

Even still, this setup still doesn't solve the issue of the stupid vertical filter stuck right into the middle of the airbox, which disturbs the smooth flow going into the bell mouths of the intake.

My opinion...
To consider the ideal setup for your bike you need to look at you usage.... the problem with airboxes on aggressively cammed engines is that at low engine speed the intake and exhaust valve overlap can contribute to "dirty air" in the air box... that is semi burnt exhaust fumes contaminate the air in the airbox contributing to the erratic low engine running... as engine speed increases and the exhaust scavenges better the air box cleans up, or as some people say the engine gets on cam, alternately it can be said to be poor low end performance... as race bikes aren't interested in low engine speed they can optimise the airbox design. Me I am a big advocate for street use of separate throttles / pods. You may remember our brother Ungeheur commenting on how impressed he was with low end performance and how linear the engine felt after pod installation...sure you can lose some of the ram effect at high end of increased airflow into a well designed airbox, but how often are you flying down a road at 200 + compared to pulling away from traffic lights or out of corners? so I feel it is always a bit of a trade off. 


just my 2 cents worth...

Raux

I regularly ride near or above triple digits, and live in a quite wet climate here in Germany. Pods really aren't an option.

DoWorkSon

Most people don't regularly run at 100+ mph, especially on a monster.

I've noticed with pods huge amounts of power increase at 65+ mph at above 6500rpm. Bike pulls incredibly harder than it did before pod filters... Plus the filters made around 5-6hp at the wheels, and that's on a 696....

However I wouldn't be opposed to trying both options.... But there is the theory that the airbox with a different filter might provide more hp, and there is factual evidence that pod filters do

I'd be more than willing to try pods vs airbox vs mwr kit...  Flashed ecu/power commander V/autotune/dyno 15 min away

Raux

again, on the dyno... it's all different. you need airspeed to show true hp while on the road.

on the dyno I would expect the pods to show more hp, then the mwr

but  you are right at wind speeds in the normal stateside range, pods may be better.
is there a difference with the rain covers on or off?

Love my pods.  But I'd be thown in jail for 100mph+ riding.  These keep the rain out >> http://www.outerwearsracing.com/proddetail.asp?prod=876811

That certainly is a strange air box design, I suppose due to limited space.
Surely a modification to open the top and run a panel filter would be beneficial, I suppose the original design does not lend itself to it. The next best thing is run pods with a well designed velocity stack.

Anyone have any backround info re this?

I'd do it but I'm not aware of a dyno anywhere close that can tune a siemens ecu. I'm sure i could get a before and after with stock, my MWR, and the new option all using my current reflash though.
