DNA Filters - Stage 3 project continued... - .: XT660.com

I would like to thank you Dino (DNA) for helping us get more power out of our XT's. These filters do work, I have spent many hours on the dyno trying to get a smoother & more powerful XT & could not have done it with out the stage 1 & 2 filters on my XTX.

Even with a few of us running big bore 102/103mm high compression pistons with high lift cams, these filters still produce the goods. Marcel & myself have tested the +2mm bored throttle bodies & the stage 1 & 2 filters still offer great volume flow with great HP gains.

So there is no doubt in my mine they work.

Dino what are the gains in HP with your new XTZ filter & top plate?

Thanks
Kev

Hi Kev,
Thank you also for the nice comments,

I will put together a complete presentation, including air flow data, dyno runs, PC3 maps, a YouTube Video etc. for the Z Just give me some time until the race season starts officially (April).
We also have some good ideas under development for the XT 660 R & X�..!
Stay tuned.
Regards
Dino

No worries Dino, I look forward to your idears on the XTX/R filters.

The bigger we go on the XT660 motor modifications the more air flow we are going to need. I am looking into a pod filter set up to get better uniformed air volume/flow as in the Raptor 700 motors.

Kev,
Removing the air box from the X / R means that many things must be relocated, that again means high cost for a complete application, because we will need to provide everything, as a kit.
So we are talking about a STAGE 3 complete modification�.! Sounds good and to be honest we are working on it!!!! Already.
Do you believe there is a market for it ? I would like to hear your opinion.

Thanks
Dino

If we can prove that extra HP can be made with a stage 3 filter then yes I think that there is a market.

I know there is extra HP to be gained from the air box & have proven this to myself on past dyno runs, I did a dyno run with stage 1 & 2 filters then without any filters in the air box & there were HP gains to be had. I have run many dyno runs testing all the XT mods & have found this motor needs air & lots of it, depending on what engine mod one is running.

I have also looked at the XTX/R's air box in detail especially the left side of the XT's air box & can't see why a stage 3 filter could not be fitted there.

I am keen to see what you guys come up with.

This sounds wonderful!

I have your stage 1 & stage 2 filters. I fitted 2in1 exhaust system and the manifolds come too close to the airbox cable and plastic so it melted it a little.

Removing the airbox completely would eliminate this and I would be delighted to see this as soon as possible!

You have me as a buyer already!

As far as I understand this kit should be a little bigger because it replaces the airbox space...

Any estimates on this? At least roughly?

Hi Dino, thanks much for your quick response to my questions.

Stage 3 complete modification? If I understand what you mean correctly and I hope I am not stepping over the boundary mentioned by Captain (if so, I apologize in advance), I would be eager to see such complete setup along with a single-can exhaust, be it DNA manufactured or partnered with someone else, plus a Tenere-specific dyno mapping. Perhaps you could offer a permutation of options here. As you probably know, there is only one after-market single-can exhaust out there (by Off-the-road in German), while there are plenty of choices of dual cans. The quality of the exhaust itself is good but the link pipe and the setup seems to be too out of place. It would be great if DNA by itself or along with other partners offers such 'complete' system - everything one needs for taking care or improving the entire airflow - I would be all for it. I currently only have your filter, but would look forward to further DNA's developments after the race season begins.

Many thanks.

I was not thinking of removing the air box, but rather gutting the inside & removing the top off it & placing a pod filter inside the air box.

I was looking at the Raptor set up something like this. http://cgi.ebay.com/ebaymotors/700-RAPTOR-YAMAHA-GYT-R-GYTR-AIR-FILTER-W-ADAPTER-KIT_W0QQcmdZViewItemQQ_trksidZp3286Q2em63Q2el1177Q QhashZitem360141995856QQitemZ360141995856QQptZMoto rsQ5fATVQ5fPartsQ5fAccessories

That's no good. I want the airbox out! :)

Hi Kev,
DNA also offers a similar ATV kit and I checked it today, unfortunately it is impossible to fit inside the XTX/R air box; again the only possible solution is the complete air box design.
In two weeks time a dealer will bring over at DNA a XTX 660 modified 700 with Akra exhaust, PC3, DNA stage 1 & 2, it will be the platform for us to develop the complete Stage 3 DNA air box.
I think we have to start a new topic at the XT 660 X section to continue this project, as we are at the XT 66O Z section.

Please advise.

Regards
Dino
