muffler brackets for my Sr4t termi equipped bike.

The bracket came out almost perfect, and with the Ti bolts drops most of the weight from the heavy/thick aluminum bracket and steel bolts.

Since I'm going to make another one, and I've got plenty of material left, anyone else want one?  I can bag probably 5-6 of them at one time.

I used 2x2 twill weave in carbon, but I've also got some of the carbon/red kevlar here as well that would look cool if you've got a red bike.

Interesting, but where are the pics? ???

Q

 +1 For something like this we need pics!!!

 I'm down for one  [thumbsup]

i want to see some pics!!!!

and i want some carbon too;;; can you do custom stuff?

this thread is useless...

you know how the rest of that goes.

where do you get your carbon from?

Sorry, I thought the pics were here, they arn't.  Even worse is I can't find the SD card the pics are on!

I'll get back wtih some pics, but yes I can do custom stuff, and I get most of my carbon from fiberglast.com

i can honestly say..HELL-YEAH do I want one

<sarcasm>

I made an orbiting space station with Death Ray entirely out of Carbon. It is staffed by Jessica Alba clones in hot pants.

Unfortunately, I don't have pics   [evil]

</sarcasm>

ps: pics!  ;D

Still waiting for this thread to come into existance ;D

 [laugh] [laugh]

If you can't find the pics, or even if you do, this would be a great time to write up a nice 'how to' thread on it with step by step photos!  I am very interested in this DIY process also.

mitt

Maybe you are my source for a Cf airbox for my S4RS!!  [clap]

YEAH!  How hard can it be?!    ;D

Uh Oh, see what I've started...  [laugh]  [laugh]

+1 on carbon airbox.  I have a 2005 S4r and would like one ASAP.  How does Friday sound?  good!   [coffee]

hey- back o' the line pal!   [laugh]

still no pics?  :(

i would love an airbox too if the price is right :)

Put me on the list!!!   ;D

Maybe over the winter I'll take on a project like that.  Either something like the airbox, or something like a fuel tank.

Camera is supposed to be out of the shop on Friday :)

I'm currently making a fiberglass breather box to replace the stocker, so I can fit a 999 shock on my bike.  I may end up just welding one out of aluminum, but I like the lightweight idea first.

bah... don't bother with the fuel tank.  not only can you get one as a DP part but the amount of engineering and fabrication would be much greater than a simple airbox.  and nobody else makes those- at least not for the S4RS.   [cheeky]

Anyone have a spare airbox laying around?  I'll take a swing at it. 

I don't mind using my own, but I'm having to much fun riding the bike to take it apart.


Since we're here, I'm also looking for side panels without the decal "plaque" like on my bike.  I'm going to mold/make those as well, but I'd rather just have them plain instead of making them with a raised area.

I know they are already available, but I'm going to do mine from a carbon/kevlar weave, with the kevlar dyed red.  Should compliment the frame nicely without being overboard.  Same with the heel guards. 

I'd like to find a front fairing (stock) as well to do that.  There are carbon ones on ebay I could buy/make a mold, resell CF part, but it's be nice not having to dish out $400 for one :)

Mebbe there is someone on the board that has already yanked their airbox for pods or ??  I will check with my dealer to see if they have a take-off or a damaged one (but still intact for the most part). The other choice is to take up a collection to buy a used one somewhere, mebbe motored-sports has one??

Thoughts?

Still looking for one, and still waiting on my fooking camera...

im designing a ram air - air box. Once the plug is done ill make the mold from glass. Then i got to shell out some cash on some 2x2 twill. I think its going to be pretty neat.

I was doing a little reasearch on DIY CF the other day myself and I found a pretty good article here.

http://www.webbikeworld.com/t2/carbon-fiber-motorcycle-parts/

For a testta or 2v ?

for my 2 v. 1995 m900. Once its done ill post pics and may design them for other monsters, if you guys are interested.

Im interested in both TAftonomos and truckinduc projects. When you finish the project a how to step by step guide would be cool  [thumbsup]

Dealer has no take-offs!  :( So at this point it's gonna cost us to buy one (hopefully used and cheap). TAftonomos, any idea on your costs to make these or if it is even doable? It is a rather complex part with the TB openings and such. Also, we need to get an open top as well, hopefully a used airbox will have a top that can be modified.

mine is a 3 piece design. You have the airbox, then what you would call the lid on the stock box which holds the filter, then the removable ram air piece which slides in from the front of the bike right below the lower triple tree.

The filter is mounted in a very different way but it creates more air box volume than stock.

The filter element itself will be a K&N made for a suzuki car.

Yours is going to be a LOT different than what I need/Testa motor.

To really get a good idea on it, I need to take a good look at mine and see what I can come up with.

It might be easier for me to start with a foam plug and go from there.  Increasing the airbox volume is never a bad thing either.

I think moulding the base of my airbox, then going from there with a foam plug, glassing, sanding, more glass, etc... to come up with a plug to make a mold from.

im starting with foam and shaping it to fit. Then i will get it just right and use it as a plug. Ill also be re- locating my battery and coils slightly. I wont be using anything off my old airbox except the rubber grommets used to connect the carbs to the airbox.
 Once the mold is done it will be easy to re-create airboxes, (as im sure you know) to sell.

My biggest problem with the stock airbox is all the litttle details on the outside. Those would be hard to replicate in carbon as it doesnt want to drape that easy. I figure the best thing for you to do would be pull a mold from the inside of the stock box.

Hmm...taft...building your own breatherbox... GOOD IDEA. i just wish i knew how to use lay carbon fiber or fiber glass, never worked with either.  ??? I already made everything to eliminate the breather box. Made a mounting bracket for the regulator, and also picked up spark plug wire so i can relocate and change the color of my wires (red). Would love to see what you come up with!

worthless without pics.

im not giving away my design

a carbon airbox for a Rs would be....titties!

BETTER than titties, cuz you could fondle/sleep with it and not get into any trouble with the GF/SO/WIFE!!  [laugh]

once my prototype is done ill probably make some to sell if i think i could sell 5 or more. I just have to get my hands on a s4Rs first.

very nice but its not real c/f is it.
Its Carbon matting in resin. looks nice but isnt much lighter than g/f and is no  use at all for structural parts
Its not pukka.  layers layed in a mold then cured in an autocalve. which iw hat you need for structural strength

I'd still get in trouble with my wife.   [bacon]

NOt if she got her own carbon fiber tits.

What are you talking about? I use real carbon. Id use pre preg if i could get ahold of it. its like 150$ a yard though at the cheapest. i predict my airbox will weigh an eighth of the stock one. and an airbox isnt wery structural, but ive been toying with doing a subframe

The airbox isn't really that heavy to begin with.  Most people will want a carbon box for 2 things.  Looks, and increased volume = theoretically better performance (especially on a 4v testa)

I'm not sure what that other guy is talking about.  Besides the fact that pre-preg is very expensive, you need to keep it quite cold to keep the resin from cooking off....and oh yeah...you need an autoclave to pressure cook it.

Otherwise you are wasting your $$$.

You guys think most of the carbon parts on the market are pre-preg? :D [drink]

Also, update on the exhaust hanger bracket.

No cracking or other problems, but I'd like to give it another week or 2 to make darn sure.  Its much lighter than the stock bracket, but that isn't that heavy to begin with.  Mainly for looks. 

I've also got some Ti fasteners on order for the muffler to bracket bolts and the bracket to frame bolt.

You're not allowed to post again unless it's with pics.

If you could buy pre preg parts they would cost 5 times as much. who would pay 1000$ for an airbox. I figure ill have about 100$ in materials total in mine when its done. It will take alot of time though, and thats the most valuable thing.

If you wanna buy me a new DSR Nikon then I'll be all over it.  Until then I've got to wait.  Camera friend guy told me Cheap or Fast, pick one. :D

I fall into the wanting a larger volume air box for my testa motor...That and it would look bad ass beyond that [moto]

BUT here is the question, I run the DP kit with the open airbox, would any extra volume make any difference in that situation still?

the lid off the airbox doesnt help in the way you might think. Its not exactly letting more air in that is helping so much, bit it is helping a little. Its changing the resonance frequency of the box. At least this is true for the 2v motors.

open lid or closed lid, doenst matter. the volume that the engine is gulping at that first hit of the throttle is based on the size of the airbox underneath the filter. (calculus shudders anyone?)
The larger the airbox, the more air the bike has to grab in the intial pull. Every gulp after that is based on the how much air the filter will allow to pass.

If you look at how our engines gulp air, you will see that there are laps in time between each engines intake stroke.  During this time, the aribox fills back up and the next stroke gulps all the air again. If i had to take a guess, a larger airbox will only help low end tq, becasue at the higher RPM spectrum, a larger filter surface area will move more air since the engine is swallong air very rapidly. A ram air would defintely help as it gives a minor force induction effect.

has anyone seen that honda civic video where they replaced the eintake with a leaf blower (litterally a 1/2hp leaf blower) the car got an amazing 7 extra hp with that setup lol. If you made a smaller box with a ram air designed (with an actual scoop sticking out somewhere) you could make up for the size by just going faster and ramming more air into the box.

IM glad you took the time to say that cause i was to lazy too.

  Thats why i like my box design. Almost twice the stock volume for low end power, midrange should be mildly mildly slightly better, then positive airbox pressure past, say 50 mph. Top end, where i feel the monster needs it most to make up for that drag coefecient.

Somewhat off topic but still related... by running say the TPO velocity stacks and a filter would that get in more air or less air than an increased volume airbox?

<serious as make the beast with two backs>
 Were do I find the Jessica Alba clones at... pics not needed, just directions.
</serious> - Chris

ps, sorry I've contributed nothing.... just want clones dammit!

I'm seriously interested in one of those.

Im in a pissed of mood right now so you get my attitude of the day....read it again, and think about it.



Now what do you think? If you still dont know. What has more area? 2 toilet rolls? or a big square box?

somebody needs a hug.  come 'ere little guy.  [coffee]

YO, master of the universe...I don't think everyone knows about that whole....psycho cutting that poor kids head off while he slept and then carrying it around on the bus......

take a deep breath...

yea your probably righ. People dont like gore around here.
edit: or  make the beast with two backsed up world.

yeah, still blew me away when I read that.....

canadians are crazy man....


BUMP for some pics

I had some thought on this air box situation. A bigger air box will contain more initial static air. Once the engine is running, negative pressure is established based on the restriction of the air filter. If you incorporate a bigger filter with a bigger air box you would get less negative pressure since more air can move throw more air filter. I would gather that the same sized air box with more square inches of air filter would accomplish the same as increasing both. As soon as you drop the hammer, that pressure inside the air box is regulated by the air filter. If two pods have more surface area than a single square K&N filter, then pods would move more air. I know on my ST, the stock box cover has two intact tracts. When I put the DP open air box kit, it made a big difference in response. To me logically the next limiter on air intake would be the amount of surface area of the filter. At least that's how it seems to work out in my mind. My guess would be if someone Dyno-d with filter on and filter off would answer the question. Has anyone done that?

you forget the way a twin engine behaves. Theres a lag time between each piston firing, in that time the airbox doesnt have much pressure, instead the it fills up back up to its static size. when the next piston is in its intake stage, it draws that bit of air again. If the amount of air that the piston draws in equals to the size of the airbox, then having a larger airbox would be essentially useless without a ram air setup.

If the amount of air that the engine sucks induring the intake stroke is greater than that of the airbox, than increasing the size would benefit. why? because its easier for the engine to grab static air than it is to create a vaccum and suck in new air through the filter (which is where a larger area would come in handy).

The issue with Pod filters is, you completely loose that airbox's static supply. Instead you have about as much voulme as 2 toliet rolls of air, more if you get a larger filter with a larger interior voulme.

Some questions you need to ask and research is, how much surface area is there on the pod filters? I assume its doubled. If my assumption is right, does doubling the filter surface area make up for the lost in static voulme? aka, becasue there is more surface area (which leads to less resitance to pull a fixed amount of air) will it make up for voulme? Its hard to answer it since im not an engineer.

Furthermore the TPO kit come with velocity stacks that changes the way air is sucked in. depending on the length and shape of the curve on a velocity stack, it can shift the power higher up or lower in the power band. TPO has dynoed their bike, there is an increase in top end only. If these results are true, than the TPO airfilters does indeed make up for the lost of voulme in the airbox (since there is no power lost and the power band remains the same at the lower rpm range). If it didnt, there would be less air going into the chamber and less fuel, therefore less power.

Regarding your statement about a larger filter with the same size box. you already have that. with an open airbox, you have the larges filter the box will fit so the point is moot unless you somehow make a larger filter fit

You will not get positive pressure in the airbox at 50mph, more like 120.

Good points. Definitely an interesting subject!

Sportrider did an extensive test and write-up on the Kawi ram-air system on a ZX9R. With a millibar pressure sensor and some other gauges they were able to see positive pressure at speeds as low as 70-80mph! Kawi was the first to use ram-air in a prod bike and has developed it far more than anyone else.
Most other systems may be as high as 100-120 befire realizing anything, it is ALL in the design. Which explains why my 9 could catch and overtake larger displacement bikes, especially at speed.

The system on the 7, 9 etc is very extensive (adds weight) and fairly complex. While it may seem as simple as running intake tubes to the front of the bike, you really need to find the high-pressure point at the nose and focus it to realize any gain. You can get some easier gains by having the system draw cooler air from the front of the bike rather than hotter air up under the tank but either approach requires a completely and well sealed/insulated intake system.

just my nickels worth...

you mean pictures of the test Hypurone did? here they are.

This is of a 4cyl jap bike

Sorry i knew you ment the carbob fiber airbox. heh

Would it be of any benefit to move the filter from the middle of the airbox to the lid of the airbox?

Do I get to unroll the toilet paper rolls? ;D

On subject..... you all are thinking of the filter as unable to pass any air to contribute to in the intake cycle...not exactly sure thats the case but the volume of air already past the filter would be less restricted on inital movement.

Wow, that is a good article...

And I have 500 or so air boxes. I would be interested in donating one if, of course, I get one in "CF".

I didn't see the thread, so I started another one.  Maybe someone can merge the 2 into 1?

How much would an airbox cost me outright if I just wanted to buy one.  I don't mind giving a discount on something like that, but I don't like to owe work to someone either. [beer]
