Another 990 Intake option?

Post by audionut74 » Thu Mar 01, 2012 11:25 pm

Looks like an interesting take on a new 990 intake solution

I know its new out but does anyone have any experience with this product yet?..... or how it stacks up performance wise to a MH or DNA MK2/3 air box?

Count me as interested and cautiously optimistic.

Interesting. Looks like it would be a lot less expensive than either of the other 2 options.

$299 sounds a lot for what you get though but you never see it....I'm still interested though! Might be purchased alongside some new exhausts when I get round to that

Coming from the dirt motorsports world I value the use of foam filters. Seemingly, the most effective are multiple density foam layered for optimum filtration.

I'm definitely interested.
I wanna go fast!

Yes, interesting.
Foam I think is really the way to go and that looks like it would flow huge!

I realize that design time is not free and that there are people in engineering that have to be paid...but $299 for a foam air filter and a base plate is stretching the limits of good taste. Perhaps there is something I'm not seeing? I don't recall what the other options cost but I didn't think they were much more than this.

Motohooligan is a little more expensive, DNA can be double the price. Not sure if there are others.

But CJ's clearly aiming at the Adventure market who value foam filtration.

Looks like a good option for off road users.

For the gains I want the roof height is still too low, from the Dyno testing I have done these motors want high speed air + volume to see max gains in Torque & HP. If I was to use my Dual Velocity stacks with this air box the stacks would be very close to the roof of this air box, this would pull most of the air through the top of the air filter more than the sides which is no problem but it would have a small area of filtering right above the stacks, with a higher roof you pull air from the sides of the air box as well from the roof if you are running a MK3 air box, pulling the air this way you have more filtered area suppling the air & should see greater gains as the filter becomes clogged up.

Also we have worked out the domed roof allows for better HP & Torque because of the shape of the lid, it flows the air better into the Dual stacks.

Not bagging this air box at all just saying the filter is a good idea but will not offer the same gains as a higher roof MH or MK2-3 air box as the foam filter becomes clogged up with the Dual Stacks.

Does the KTM needs a lot of air: YES.
Does it need to be a raised roof for the best gain: NO

The engine need just a big airbox for the best gain, because on KTMForum.eu a user called @highscore (also on superduke.net) did the following with his low profile airbox.
He made a hole in his airbox base plate and now uses the bottom of orginal ktm airbox as a buffer. And now you see similair gains as a highraised roof.
This clearly proofs that just a big airbox is needed (lots of still air).

It does with the Dual velocity stacks we have produced & I have the Dyno runs to prove it on 3 different 990 KTMs, which was the coments I made If I was to use my Dual Velocity stacks with this air box the stacks would be very close to the roof of this air box.

I know High score very well & think their air box is a great air box, but my comments still stand we got more HP & Torque from a higher roof air box using the DUAL VELOCITY STACK that we have made.

I got the filter today and have some RC8 stacks also

Dyno is booked for 9 may (tuneecu mapping)

I'd be curious to know what the flow rating for that filter is in comparison to the MH & DNA filters.

the base and top of the box next week will be in carbon, in a month i hope have a diferente top with more air capacity its under construction...
