ECP MOD (Maximum Oxygen Delivery) Airbox final results.

[SUPERTUNER]

I am happy to say that our MOD airbox dyno results are finished. I have successfully been able to get this done, but it wasn't easy. I am here to tell you all that the stock airbox is one seriously finicky sonofagun!

Testing yesterday and today went as follows:

Weather conditions were identical the last 2 days. We are now making more horsepower with the MOD airbox than we are with the air kits both at peak and through the early low end and midrange. The ECP MOD airbox absolutely crushes a stock airbox...everywhere!

The difference between my air kits and the MOD airbox on the dyno however is that the MOD airbox makes peak power between 9400 and 10,300 RPM's. The air kits are capable of making pretty much the same power from 9400 all the way to the rev limiter with no drop off until the engine hits the rev limiter.

What this means on our inertia engine dynamometer is that the power under the curve has been dramatically improved. This translates into making more HP in less a duration of time. This is the same phenomenon that my air kits did versus the stock airbox.

What does this mean to people who already have my air kits? If you are wanting max MPH over extreme long distances, stay with the air kit. If you want to reach your max MPH in shorter time...go with the MOD airbox. The advantages of this are that you can now load a lot more weight to your clutch ramps thereby squeezing the belt harder and keep yourself from "driving through the clutches". I see this as an davantage to everyone but the riders who ride in the mountains are going to love this MOD. The reason being is that the increased torque not only makes mountain riding more enjoyable but the heavier weights will backshift quicker to keep the deep snow riders more on and more repsosive to their power range.

Now here is another thing that I didn't want to tell anyone until now...the MOD airbox will require you to modify your hood. Done correctly, it is a sano install and turns you RX1 into a true forced air pressurized airbox. I tune seriously fast 200+ MPH sportbikes, dragbikes and land speed bikes at ECP almost everyday. Pressurized airboxes turn 180 MPH motorcycles into 200+ MPH motorcycles and the same is going to happen with the RX1. THis is where we really won't know the true advantages of this mod until the snow falls and someone gets the MOD airbox out and tries to go 50, 70, 90 and 100 MPH. If my dyno was in a wind tunnel, I could actually see the advantages of the MOD airbox in a real controlled environment. So...I made my own "makeshift" windtunnel where I mounted 4 compressed airguns in a manner conducive to blowing cold air at the MOD airbox. The result was on these tests, I registered over 142 HP. Without the forced air induction, power peaked at 138. Although this was not the environment that the engine is going to experience on a lake or cold winter day in a field, it proves that the forced induction works and works well! At 90 or 100+ MPH you will be able to feed a lot more volume and also colder air than the "makeshift" forced air I constructed. I tested with 180, 185, 190 and 200 size main jets. Sitting still in the dynoroom with a smal fan blowing air around the sled had me in the 180 and 185 size range. The forced air induction resulted in me needing to go to the 190 and 200 size main jets. More fuel required means that more air is available. I cannot say this yet for certain but I do believe that once someone gets one of these MOD airboxes out, they will run a faster top speed than the air kits.

If forced air induction didn't work, every major motorcycle builder on the planet wouldn't have ram air. Greg Anderson, Warren and Kurt Johnson and the rest of the NHRA Pro Stock car and Pro Stock bikes wouldn't have hood scoops and forced air induction. It becomes basically a "natural" turbocharger" in a small sense.

I'm afraid that I am still awaiting on some prices for the rest of the parts to make these kits up so I can't tell you all how much they will cost, but I will as soon as I know everything...probably only a day or 2 away for the rest of the missing prices.

Now my question to all of you...do you see cutting additonal louver cutouts just like the ones that are already in your hood right behind the stock placed ones a big problem?

What I intend to do is provide a template and another aluminum frame like the stock RX1 has and all you will have to do is under the original hood louvers near the nose and have you all install these parts. This will be the forced air inlet for supplying the massive amounts of air that this new MOD airbox needs. It should only take about 1/2 an hour to perform this hood modification. Your thoughts???

I also intend to offer these for the 3 cylinder 4 stroke Yamaha sleds. I just haven't had the luxury yet of getting one in the shop. If anyone wants to step up, I will make it worth your while. Even if it is brand new and not broken in, I could lay it all out thereby making it easier to release once we get the chance to test it on the dyno.

One more thing...I know this is going to create a lot of questions and rightfully so. If you would, please post the questions here so everyone will benefit from being able to read it. It also cuts down on the amount of telephone calls and PM's that I get.

Speaking also about PM's...I would rather you forward any questions or remarks that you don't want to put on this forum to me directly at KliesECP@aol.com rather than using the PM option on this website.

Thanks,
Freddie

I would do it in a minute but I would want it to look good too. How about supplying the fiberglass or plastic scoop needed and have cubby get them chromed. If that is the case consider one sold already.

Jeez Freddie, I said you could test my sled, but I didn't say you could cut holes in my hood. By the way, how do the holes look with the ghost flames??????------Cubby

 

[Sled Dog]

Have you got some pictures so we can see what it will basically look like. A picture is worth a thousand words for something like this. Besides we want to see the holes cut in Cubby's RX-1. LOL

 

[welterracer]

Do you have a graph comparing the torque and hp from stock to the new MOD version for comparison??

You could draw a pic if needed!!

What other gains besides lower rpms hp is there?

Hmmmm, might this explain some guys loosing top end with the filters? Most thought it was because of the excessive crank case pressure. I'm not so sure now. I think some kind of forced airflow directed to the filters can help them also.

I understand your theory on it helping the mountain guys - but I see one major problem - snow intake. Does the modification still allow air to be pulled in from under the hood, or are you blocking the stock intake off?

Man, to bad season finals are this weekend on the tar, would love to test this at the track. Finals in Fargo/Moorhead are Oct 2nd, maybe I could get one of these kits in for then!!! How does it look with those extra vents in the hood???? It has to be effective, but has to look good too!!! Freddie let us know when you have pricing on these and when you can start shipping.

 

[SUPERTUNER]

I have no pics to post or send to anyone. Frankly I don't want either before I have the entire program detailed with prices and everything else. Like I said earlier, I have some prices still waiting to be received and as soon as I do, I will be happy to get averyone some pics. I will also be advertising these here on this website and the pictures will also be on the ad.

Mightywarrioir...nice try but the Air filters provide more air to the engine than the stock airbox does.

Welterracer...I have lot's of dynographs, but like the pictures, I am not going to release them until all is ready for me to sell these as a kit. The other gains are an incredible improvement of power ealry in the run and heavily through the midrange than the air kits. The ECP MOD airbox destroys the stock airbox badly!!! For example the stock airbox makes 66.6 HP at 6400 RPM's. This is admittedly a downward spike, but the stock airbox doesn't dyno well and there are horrible peaks and valleys throughout the stock airbox dynorun on the graph. The ECP MOD airbox makes 94 to 102 HP at 6400 RPM's depending on how I situate the inner parts of the MOD airbox. The end result is a much quicker acceleration to peak power.

Cubby...those ghost flames were easily removed when that can of laquer thinner fell on your sled...sorry.

Actually, I didn't cut your hod at all. I will wait and test the ECP stage 2 engine package with both the mod airbox and the air kit. I have seen some pretty wierd things happen that make little or no sense.

Please be patient guys. This is happening a quick as it can.

Snow intake will not be a problem. That is all I can say at this time. I promise to divulge all information when the time is conducive.

Yea, I know you didn't cut my hood, but I had to mess with ya. And yes Freddie, on my actual sled I would expect you to test all 3 set -ups after the stage 2 is installed. What ever makes my baby run the best is what end result I am looking for.

Now about that can of thinner that fell on my hood......................Cubby

I agree that forced air works. Remember the ram air Hemi's? Don't the Firecats have ram air?

Do you think the ram air worked on the Vipers? I know it didn't go directly into the air box. What about snow injestion?

Isn't there a point where the ram air will start working? It seems like the forced air will have to be faster than the speed of the air normally through the carbs, at any given speed. It seems like it would only help at the higher speeds. If it helped at moderate speeds, wouldn't it be on all cars, even the compacts? The carmakers would love a cheap hp gain. Wouldn't you gain gas mileage also?

I know there are enough people that would do anything to go 131mph instead of 129mph, to make it a successful product, but I just wondered if the old guys, with common sense, can benifit from it also.
