ECP MOD (Maximum Oxygen Delivery) Airbox final results.

that too cool!! im new to the 4 stroke sled. i have a raptor that hauls the mail, it just has open k&ns on it. this ram air sounds like it will have to be on my 05 warrior.
 
I ran my mod air box early last season and then went to the filters because they were legal in stk class drag racing and mod air box was not.
after the racing was done i went back to the mod box.it was a lot less noise and ran a little better.the noise makes most people think they are going faster and might not.this sled run's really good both ways and even took first place in the radar runs at west yellowstone last year in 700 mountain stock :flag:
 
Last winter I played with a ram air set up with the filter kit. Just made it out of cardboard, it did make a power gain but. I could jet the main jets up enough, to 180. I richend the needles all the way, it was simply too lean to maintain a constant speed over 50 mph with less than 3/4 throttle.
 
I have one of the ram air bikes and it depends on speed how much air gets pushed into the intake tract I did som e reading a while back when the did some extensive testing on a Kawi I think. At 80 Mph the gain was like 8 HP and anyone that knows bikes knows 8 Hp is alot on a already strung out rice rocket. it did not multiply evenly in other words 8 HP at 80 did not mean 16 at 160 but it wold increase slowly. Freddie do you have like a stage 1 mod maybe some airbox tricks but no hole in the hood for those of us scared to cut a hole in our new hoods but want to keep airbox???
 
Freddie , I am in the process of building a dash pod that wont explode into pieces. Have been working with Outlaw hoods and Mitch Evans who built my carbon fiber tunnel. Would really be interested in designing a one piece hood (either gel coat or carbon fiber) to incorperate your kit rather than building just a pod.

Also will be sending you a copy of the artical from Sledhed magazine from last year on my sled.
 
It sound to me that you guys are working on a simular product to what we built and tested on 5 sleds, last winter, with great success and no hood modifications. Good luck. Can't wait to see if it can compete with our technology in overall performance.

Yikes. I'd have to agree. Such a beautiful sled to be hacking holes in the hood. Then again, memories of a Bender cold air kit come back, and that worked pretty good.
 
I think you guys are nuts cutting that gorgious hood. Unless the performance stomps the K&N's go with them. You loose weight, have easier access to everything and you don't cut nothing :ORC

Freddie, why not remove that metal plate between the hood and belly pan instead of cutting the hood up?
If you're concerned that the bumper will obstruct airflow remove it, it isn't good for anything anyway ;)!
 
OK, Now you have gone and done it. You guys got me thinkin about this cut the hood thing. There is a metal plate that is riveted to the hood hinge that is steel, (I know this because I chromed this piece) and it sits behind the front pointy bumper. (Which I hate and want to replace with something chromed). Could air be forced into this area???? And my second point, I have a good friend who owns an injection molding shop and if we can make a good engineered drawing, he will make a mold and pop out about 100 of these well designed hood scoops. You know, hood scoops to force air into the existing v-shaped hole in the existing hood. These hood scoops could be put on the hood with 3M 2 sided tape( which at my new job we use to put on ventvisors, painted hood scoops, and sunroof wind deflectors). These scoops could also be painted to match the sled or ..............CHROMED. Sorry guys, just thinkin out loud here..........................Cubby
 
I dont like the thought of cutting my hood either,the performance gain would have to much better than the filter kits.I like the idea of using the vents that are already there,Cubby i like your two sided tape scoop idea it is a good solution to the cutting the hood.have to wait and see what freddies design looks like to eye it up.

Right now, I don't have anyone that is willing to let me cut the vents in their hood. If Cubby's sled makes better power with the airbox than the filters, I am sure he will allow me to do this. I agree that the power however has to be worth it. I cut fairings on bikes and other sleds all the time and they come out perfectly. Frankly, this will end up looking so good that even if you ever wanted to go back to the filter kit or even the stock airbox, it will not look out of the ordinary.

In my opinion I think you guys are freaking out too soon about the vent holes. Like I said earlier, the power is worth about 10 HP through the midrange and about an additional 4-5 at top end over the air kit. I personally think that much of a gain on an already highly tuned sled warrants this to be done. Plus I would never do anything to make a sled look worse.

Wolfie...you would only be "hacking holes in the hood" if you are a hack...sorry but I am not a hack.

Scooby...unless you have direct ram air to a sealed off airbox thereby turning it into a kind-of "plenum" you will not experience the type of gain that a true ram airbox garners. I am sure what you have done works well but I am 100% certain about this statement.

Pinball Wizard...feel free to have Mitch call me if he wants to try and put together a cooperative effort. That would be the ultimate!I look forward to seeing the article. From what you have told me in the past, Mitch sounds like someone I should know for sure!

Mightywarrior...It is totally reasonable that the true :ORC will come when someone gets the MOD airbox out, tunes the clutching correctly and sucks the headlight out of an air kit equipped sled. Although this hasn't happened yet, the dyno data indicates that it very well could...and with resounding confidence! Regarding the metal plate...once you see the airbox MOD,you will understand more.

If Cubby gives me the okay to do the mod, I will do it, take some pics and send them to you. Besides, the additional air even to the air kit won't hurt out in the field. I tested the MOD airbox versus the air kit in both ram air and still air conditions and the MOD air box outperformed the air kit every time. Done correctly, the mod to the hood will look radical. You guys should se the Hayabusa I am building for myself...you would then understand the quality and ease of doing this kind of work and the rewards it presents.

More to come soon. Thanks for all the replies as I do want to give you all everything that I can but my main concern is to offer you more performance at a reasonable price. Draw a triangle on a piece of paper...in one corner write the words "low price", in another corner write "fast serivce" in the last corner write "high quality". Now pick only 2 of those choices because you cannot have all 3. This is the way business works.
