ECP MOD (Maximum Oxygen Delivery) Airbox final results.

Ladies and gentleman, please forgive me for not replying sooner but I lost a very close dear friend last Thursday evening. He was tragically killed while riding his bicycle when he was hit by a Dodge van. I might be a little less attentive to this forum for a little while but please trust me that I am coping as well as could be expected and still making headway on this mod.

RobRX1...that pic of the modded hoos is real close to what is going to need to be done. In my opinion, this makes it look better...not worse. The only thing different about the vents required for this MOD airbox is that the vents won't have to be as large as the ones in that picture. They will be excatly the size as the OEM ones already in place. They will direct replica's tp those already there. There will simply be another set above the stock ones...very much like that pic shows. Thanks Rob! Good find. Had I know that was available, I would have directed everyone to that.

QCRider...I don't mind questions. In fact I have been around this industry so long, you come to expect them. How ever when someone seems to be "challenging" me and demean me or my companies efforts, this when the gloves come off. I don't think you stepped over that line and I take no offense to your questions. I think it is smart to be questionable as very often there are indeed somethings to give up to gain in other areas. But, until I actually have the luxury of riding with this MOD airbox, I don't believe I will be able to answer your question 100% accurately. Therefore I am going to make statement "as to the best of my current knowledge".

It appears that you are a "pessimist". I am an "optimist". I see this MOD as increasing the value of the sled, not decreasing it. When you invest in performance or appearance this is supposed to create an environment where you increase in value. If you installed an high performance exhaust system on your sled that required to cut cut additional holes in the bellypan or whatever this would be reflective in the price that you add to the value of the sled when you try to sell it. See...I would charge for cutting the vents in someones hood, therefore it makes perfect sense that this is indeed worth something! I fail to see the reasoning of someone thinking that this shouldn't add value. The other alternative is to always be the last one across the lake or field when you and your buddies line up to race. If this makes you happy then the MOD is not for you. Simple huh?
The OEM's create a design of may things on sleds, bikes, cars etc for many different reasons. Some don't immediately make sense but the engineers do have viable reasons for their designs. Some of them in the case of the airbox might be (but not limited to) noise, cost, fuel economy, looks, ease of manufacture, ease of maintenance. Why do you think the aftermarket is so big in the motorcycle, snowmobile and automotive fields? It is because people want to personalize their vehicles, make them faster and look better.

The evac line will be in stock location and configuration. Fact is an electrical pump is required to really evacuate the crankcase properly. These ar available to anyone wanting them too. E-mail me with any requests. The RX1 does carry quite a bit of crankcase pressure. These pumps should not be worried about however in my opinion for anything except in a racing environment.

Not sure if I covered all the questions and if I did miss something, please ask again or e-mail me directly.

Freddie you stated in an earlier post, "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". Then you stated that the MOD has an additional 10 HP overall throughout the range. In the second statement are you comparing your first kit to the airbox MOD? I just want to keep the numbers straight. I can't wait to see the dyno numbers of the new MOD vs. the stock airbox you did last year. How long do you think you need the sled to do this MOD. No hurry, let me know when you have the answers. Thanks, Dana.

BostonRX1...the MOD airbox out accelerates both the air kit and the crushes the stock airbox. The air kit does hold a candle to the MOD airbox but the MOD airbox still does outperform and out accelerate the air kit. I do have dynoruns showing 10 HP gains versus the air kit as well as the airbox. This all depends however of how I situate the inner parts of the airbox. The plastic tray, the screen and the foam as well as the snorkle at the bottom all result in different dynoruns. If you leave the foam out but leave the plastic tray and the screen in, you get a different "personality" of dynorun. The same is said for the rest of the parts inside. I will be selling the kits with instructions detailing what will happen when this parts is removed and that part kept intact etc. There are so many combinations and variables that it is literally impossible to put into print. I will however make it as neatand easy to understand as possible.

As far as doing the work...I could do this whenever you are ready. It would only take me 1 day to complete the job unless you would want me to predyno and after dyno. Then it should take me 2 - 3 days in shop time. This doesn't mean that Iwill work on the sled for 2 or 3 full days but due to scheduling in the shop, it means that I need to take care of walk-in customers as well as tlepehone when I am needed. I am gathering prices too on this and will post them soon.

Thanks for everyones interest.

Hey Freddie on the Hayabusa, Have you done anything besides the small and large airbox mods that help out in the HP dept. Maybe I would be interested in sending my airbox to you for some mods. I am not ready to go crazy I have a 00 with Two Brothers 4-2-1 BMC race airfilter PCII I was considering doing the small airbox mod and block the pair valve holes. I am looking for alittle more power without getting into my engine. I would like to break 200 with it someday

At this time, I only do the minor and major airbox mods to the Hayabusa. I have tried several different things with the Hayabusa airbox but to date nothing works as well as the large mod for power. I have tried some specially built carbon fiber ones with different inside shapes as well as my own "doctored" up inside shapes but have yet to match the power outpout of the simple large mod.

Frankly, the ram air on this model and the other motorycles that use ram air technology as well as my Pro Stock Motorycle experience has pushed me to want to develop the air box I am now beginning to market for the RX1.

Thanks for the inquiry though but a large/major mod on the Hayabusa will produce the best racetrack results and the small/minor mod is best for street requirung air filtration.

Yea buddy, you didnt answer my question: What is this wonderful new airbox made out of?????--------------------------------Cubby

It is a stock airbox that has been modified. Therefore it is plastic and cannot be polished...sorry.

Ok, fine, Mr. Smarty Pants. Now do you want my stock air box??? It is being used to collect dust in my attic. I would be more than happy to send it to you....................Cubby

Do you send us the stuff to mod our air box or do you give us a core credit when we send you ours back or do you not want ours back?
 
not to disagree with any dyno results but from an engineering point of view, using the bernoulli equation on an example of a sled traveling at 90 MPH. Assume that the velocity of air through the scoop is the same as the velocity of the sled, (an ideal situation), you could derive that the change in pressure generated @ 90 MPH would be equal to [the velocity of the air into the scoop squared (90^2), divied that by 2 times the accelleration due to gravity (2*32.3 ft/sec^2), all the multiplied times the specific gravity of the air into the system (0.075 lb/ft^3)]. This gives you your pressure rise aka BOOST from the ram-air, after plugging in the numbers the theroretical boost would = 0.141 psi @ 90 mpg, which is almost neglegible. So id think a ram effect is unlikly, but do think that a denser charge and definatly more air flow will make nice results. By the way i still love my ecp kit

Jeez Cowboy...ya had to go and bring Uncle Bernouli into the equation! Despite the fact that I am aware of Bernouli's Theorums, there is only so much scientific jargon to take you along the route to success with any product or service. It is like trying to explain my porting...up to a point it is very scientific...anything beyond that becomes a "black art". Frankly most success is founded in the fact that it is just simple logical thinking. I like nubers and theories as much as you do but Ialso realize that there have been times when something has worked when you would think it wouldn't. Therefore I go by this remark..."When the results don't agree with the theories, believe the results and get a new theory". Do yourself and all of us a favor...don't let this get into your head too much. If you believe that ram air doesn't work, there is no help for you. Fact is, I have seen negative air pressures inside some airboxes even with ram air capabilities. Imagine what the negative numbers would have been without ram air! Ram air works, next topic of discussion.

Cubby...yes, send me your COMPLETE airbox please.

Mighty Warrior...I am not sure how I am going to sell these yet. What do you think woulld be the easiest for you guys? The modification is only done to the lid at this time. Would it be best for me to supply you all with MOD lids or would you all like to send them to me? I could also sell you the kit for you to install to. I suppose there is going to have to be a few different programs for all the folks out there.

Silver...thank you. He will be missed.
 
like i said there would be some boost generated but what is a 1/8th of a psi going to do to performance compared to the gains through the massivly increased airflow and denser charge. I just thought that after reading all the posts and hearing some people thinking theres multiple hp to be gained through a ram effect whne really there shouldnt be, i simply think the reasons your kits make good power is the air, more air and more fuel plus a denser charge equals more power. ;)!

Okay, until someone comes up with something better than that, we will go with your train of thought. Thanks for the info! :Rockon:
