Is there anyone that is willing to take a few detailed pics of their FAST system with it off the bike? Possibly measure height and OD top and bottom of the funnel. I would like to make an attempt to fabricate my own version. | ||
| Brineusaf |
I have one, however I am not willing to take measurements, sorry. Shouldn't be hard task though, once you have the measurements. | ||

FAST system? im new clue me in please. | ||

Somewhere I have a dyno plot also with this kit before it was dyno tuned,after some dyno tunning, the full dyno tune was simmilar as only the fuel curve was flattened out. | ||
| Fullpower |
there are no published performance results, at least on that thread. | ||

Look at this site for some picts http://www.hillbilly-motors.com/html/buell_f_a_s_t.html | ||

Ok, Eric. I've seen that pic about 5,243 times now and I am finally going to ask: Do you really ride it like that? | ||
| Firebolteric_ma |
oh yea i ride it JUST like that....all 5,000 times! here is the dyne plot before much tuning was done. http://www.badweatherbikers.com/buell/messages/32777/214388.html | ||

I've got the two breather filters tucked underneath the barrier, due to my not wanting to puncture it until I have my "great idea" completely formulated. But I run mine with the Turbo Airbox Cover. Definately increases intake noise... love it. I'm pretty sure I've experienced an increase in "something" for the better... but alas I don't have any plots. | ||
| Firebolteric_ma |
Them are some older photo's in the work computer here. Maybe I will update them as the bike is a little different now. That small filter is now used on my home made catch can set-up. The filter is now under the seat attached to the upper portion of the passenger mount. | ||

MY own version (FAST inside the xb9 airbox to reduce intake noise....and it works!!) note the thermal mat under the base of the airbox. http://www.devilstars.com/forum/viewtopic.php?t=358&highlight=modifica+airbox (Message edited by xxxb9s on October 16, 2006) (Message edited by xxxb9s on October 16, 2006) | ||

I don't think you're getting the same airflow as Eric or myself. It appears you be facing..still.. some restriction with airflow. | ||
| Brineusaf |
Ironheadsporty - sorry, I ignored your question.. I really just overlooked it. FAST System : K&N Filter Heat Barrier/Base Velocity Stack Allows you to remove the stock airbox completely. And I think (as in My opinion) that the FAST system would give better airflow than the open airbox kit, and looks better. | ||
| Firebolteric_ma |
I don't think the FAST kit would fit in the airbox as shown. The velocity stack would raise the filter up to much. JMO | ||
| Xxxb9s |
I don't care if you don't think it would fit, it simply does,I ran it for over 6000km so far and it kicks asses. just let me get it straight, do you think I'm wasting time photoshopping my pictures to make myself "cool"?? bah! another thing, FAST showed no power loss compared to the total open air version, it just decreased its intake noise, but the airflow is still the same since the hole I drilled in the airbox is just more than enough to allow the entrance of the necessary (and maybe more) air that the engine needs. cheers (Message edited by xxxb9s on October 17, 2006) | ||

Indeed, my velocity stack raises the airbox quite a bit; in fact I'm not sure if my stock airbox would fit on it, guess I'll see later. Do you have DYNO PLOTS showing that the FAST SYSTEM is the same as YOUR SETUP? I didn't say yours wasn't supplying ample air for intake, I was saying that your setup has more resistance the the FAST SYSTEM. Pretty simply. You have small holes which allow air to get to the filter... I have large intake holes... and Eric has open atmosphere. But yours provides the same resistance as ours? Let see pics of the velocity stack you are using, or pics without the airbox attached of the naked filter. Yours would amount to a stock 07 airbox (almost 06) with the exception of the K&N Cone. They have the same concept, increased airflow throughout the airbox as well as the airbox cover. | ||

 I guess it does fit. YOU are right.  If I push the entire filter OVER the entire velosity stack it would fit,barely and is squishing the filter!(restricting airflow) I just tried it for kicks and giggles. Very tight fit. but you do what makes you happy as I DON'T CARE!!  I can just barely get the airbox "skin" over the filter/stack and it is tight, to put it in the airbox is even more restrictive as you need to push the filter down over the stack which would restrict the air flow even greater and the way the air stream enters the motor. get it on the dyno and see for yourself! show me the numbers! No one said anything negitive but if ya want to get all huffy puffy like one of the old ladies I'll jump at this!  Photo shop.......  (Message edited by firebolteric_ma on October 17, 2006) | ||

Weird. My FAST system fits just fine. | ||
| Hogs |
oh yea i ride it JUST like that....all 5,000 times! Firebolteric, You mean you never have rain plm. issues with that?? | ||
| Firebolteric_ma |
I have not had any problems yet. If I do get cought in the rain w/ the cover off I just re-oil the filter when I get home. I have checked it in the rain before and very little water actually gets to it. maybe some mist but that is about all. If I know I will be riding in the rain I will put the cover skin on for the ride that day, just to be safe.  | ||
| Glitch |
5,000 times! How many miles?  | ||
| Firebolteric_ma |
well 17,000 miles on the odometer...so...um...uhh..I need to get out and ride more often. That is only 3.4 miles per ride, bought it 2.5 years ago, if I rode every day (which I don't due to New England Weather)it would be 912.5 days of ownership and I would need to take it out 1.61 times per day... Now how am i going to pull this off with the wifey?  | ||
| Brineusaf |
I ride in the rain wth mine, but i have the turbo airbox... but rain still gets in (obviously... i don't ride backwards). I just think the only way to get the full effect is to either run an "open atmosphere" or an airbox designed for compatibility with the System. Granted, other setups will "work" but... I work hard for my money, and I want my money to work hard for me (song?). If it works for you then great... What you need to ask yourself is "Is this good for the company?".... wait that's not it... "Are you happy?". I am... | ||
| Xxxb9s |
I still don't care your doubts in fitting the system in the airbox, I ride it and that's enough to make me happy, try it yourself, if you need proofs, I will not for sure waste my time trying to convince you. Not to mention you are offending me not believing what I'm saying, but once again who cares, who are you?.. I could also add that the airbox cover needs more "pushing and pulling" when placing back its bolts in their holes, and the holes are slightly deformed (nothing that plastic can't handle)...but why wasting time writing..... no dyno curves available, sorry for those talking about "you drilled small holes" you probably missed the "halfmoon" BIG one on the top of the lid, not to mention the airbox "frame hole" (xb9 2003) that is still in place and works as always. the system takes all the air it needs "believe me" (ah ah ah ), maybe you also missed that the top of the "mushroom" raises on the top of the airbox and it basically is....outside it. no I don't need more air cheers | ||
| Ejiii |
My FAST system also fits fine under the airbox cover. It works awesome, maybe not as good as no airbox cover at all but it works! | ||
| Brineusaf |
Don't get all bent out of shape. If your setup works for you then GREAT. But your saying that required more pushing and pulling just confirms that it wouldn't fit properly when positioned for maximum air-intake. But Alas...enjoy. | ||

Calm down friends, as long as You use stock heads You won´t take the FAST system to its limit even if You partially shroud it with parts of the air box. The heads limit air flow through the engine when using the FAST system. How do I know? One of our 1170ccm engines with modified heads pulled 108hp on the wheel using the FAST system and a Deep Thunder Exhaust otherwise beeing stock (cams, compression, valve size...). So the air flow capacity of the FAST system is high enough to feed modified engines meaning that it will be way enough for a stock engine even if it is partially blocked. Still if You run a highly modified engine I would recommend not to use the air box cover. Best regards Alex | ||

Thanks Alex | ||

Xxxb9s QUIT BEING SUCH A TOOL! If it works for YOU then that is all that counts. I mean really...who cares, right! Surely none of us really care how your bike rides in all reality. JEEZ! No one doesn't believe you...really..I believe it can be done as you have it, was just commenting on something, THATS ALL!!! YOU do not need to prove a thing. just making conversation with asking for a picture, I mean doesn't a picture say a thousand words? maybe we could learn something from your set up....OR help you make it better with some pointers..I don't know. OFFENDING YOU......  ....My you get your panties in a bunch easily. NO OFFENSE WAS MENT!!! I will say "SORRY" if I hurt your little feelings. There should be some clarification as to the "Air box" and the "Skin" or cover. The FAST kit in the "Air box" pushes the filter over the stack to a point you are not getting the full effect of it.(NOT that the buell can use it all anyways). It just raises the stack further up into the filter...like halfway into it. You can also use just the "skin"(with no air box) on the system also as I have been known to do when it rains. This is also a TIGHT fit when the filter is on the stack "Properly", BUT it will fit. | ||
| Firebolteric_ma |
EXCELLENT point there alex! Now I need to get my heads done. Winter is on it's way. | ||

I gather its time to shine a light on the miracle of the FAST system. The Buell XB comes with a perfectly fitting airbox base plate. Who wants to get of of this and exchange it against a flapping mat with no proper connectors for the head breathers and the air temp sensor?...............nobody. The velocity stack is a problem. So I suggest to get yourself a bit of aluminum get it shaped by a local guy and use the air filter cover that Stefan Freitag in Germany has developed together with a big K&N Filter. Use the base of the rubber stack as the seal for the Aluminum part. You just need to cut this a little and you have a much better and cheaper solution. tiger | ||
| Brineusaf |
Tiger - Where do you live? I've only seen myself, and another Bueller (my friend) in my area, which appears to be your area as well. | ||
| Brineusaf |
Ok, my problem with the stock airbox base - it wasn't flat, and contained areas in the rear of it, where debris could become lodged. As far as the breathers are concerned, make a bracket or purchase one (HBM has one) which connects the two breather filters to add stability and a professional clean look. As far as the air temp sensor is concerned, cut a hole in desired location, install metal gromett, then install the rubber gromett you removed from the stock airbox base, then simply insert the temp sensor. IMO if you intend to pursue more dramatic engine modifications then improved intake is going to be demanded regardless. I don't like the idea of having to put dissect stock pieces to save a few dollars, I like the idea of a well thought out product. Tiger - we need to get together one of these non-rainy days before the snow starts for a ride. | ||
| Tigerbythetail |
Precisely........I love the idea of a well designed product..........the FAST does not cut for me anymore. Got one and done it better.........the stock rubber makes a very good seal. tiger | ||

I have a FAST system sitting on the shelf. I did not like the way it fit on the throttle body and the air filter was a bit tall so it interfered with the stock air box cover. I'm pretty satisfied with a modified American Sport Bike open air box system and base plate. |
