I've ordered from ironmachine a couple of times. They have great customer service. | ||
| Hogs |
IS there a FAST for the 12 out ?? or is it just for the 9 ?? and whats FAst site? www. Thanks | ||
| Dscak |
Hogs, Ironmachine.com & yes they have one for 12, but its listed as out of stock right now. Have one on order. Dan | ||

Hogs, if you can read German or simply e-mail Jens, you may be able to get a FAST directly from Hillbilly. www.hillbilly-motors.com You can try BabelFish-ing it, I managed to make my way almost entirely through the ordering process even without it. | ||

Okay I know they have tested these but did they do all testing on a 9? just curious.. also with all the mods .I did so far, D&D, K&N,box Drilled,snokle removed, race ecm, IS there any gains to be expected on a 12 with this fast setup?If so how much HP. and torque??? Just seems if I remember they didn`t have a 12 box which we all know makes a difference on a 9, plus with the drilled air box, Hmmm just wonder if its worth it etc. etc.?? Thanks | ||
| Hogs |
Anyone??? | ||

The mat I can make myself. Breather filters I can buy. Make a bracket for the Temp sensor. Run the stock 12 box cover cut down to just fit the shape of the K&N and buy just a velocity stack from whomever you think makes the best stack. I have a 9 muffler that just arrived and I'm thinking maybe I'll do a little experimentation. Look how much money I saved Honey!?!?!?!?! | ||
| Odie |
And the more I think about= I'm not racing or anything; I just want the same or more power but it also to sound like a v-twin, not a sewing machine. I wonder now if I'll ever get a race ecm due to some of the problems being reported on 12's. Don't know.................but I don't like spending tons of hard-earned cash for minimal results when I can make things myself and at the very least stay where I'm at or make a little more power.......... | ||

Odie, you've just hit on the reason why I drive a lot of people nuts asking all the questions I do. 1) I love the satisfaction of doing it myself. 2) I'm a cheap bastedge. Or if I can't do it myself I want to know what works best, and a lot of the time I can't stand it if I can't find out why it works best, and how it works. | ||
| Odie |
That's one of the reasons I'm a maintenance test pilot!! I'm with you yet again Glitch.........this is getting scary! | ||

ROTFLMAO...Odie!! Sikorsky is that the one on your profile? Balls of steel... | ||
| Odie |
Yea, that's me. Best thing in the air!! Just like we wait for new bike models I wait for new helicopter models! The "M" model is coming out soon with new avionics, more power, faster, etc....it's all the same, just different toys...... | ||

Took the Dewalt to it last night and WOW! That dip in the torque curve has vanished. Anyone who hasn't done this is really missing out. Sounds great and pulls real hard from 3500 now. Wheelies are extremely easy (easier). I was having so much fun with the new found mid-range that a guy stopped his truck and threatened me to stop running up on him (oops!). Cheap power rules. | ||
| Deerhunter17 |
Added a little Dewalt usage to mine today. Had to see, figured I could replace it easy enough..... I can't believe it makes that much difference. I rode up the highway @steady throttle for a few miles. Seemed more responsive. THEN.... I was leaving football practice ( I coach a youth team) wound out to about 3800 to 4, cranked the throttle, UP she came!...... No way! Too Easy! | ||

An interesting thing just struck me, but maybe it's been hashed over before. The midrange dip I always assumed was caused mostly or entirely from exhaust system compromises (diameter, flow, noise, etc) resulting in reversion of exhaust pressure. This was mostly taken care of on the 12 with the exhaust bearing. But now we/I'm seeing that opening up the intake also helps to fill in this dip. It sounds like drilling all the holes does more for the midrange dip than it does for the top end (although it helps a bit). So drilling the airbox cover, instead of letting the engine breath more air, might really be fixing (or altering/reducing) an airbox resonance (intake reversion). I'm sure Buell didn't want to put up with the comments about hanging a breadbox off the side of the bike like the tubers. It's a compact bike and Buell found novel locations for the oil and fuel tanks but air volume is hard to cheat. Multi's would probably lose midrange by dumping the airbox. My VFR800 has a flapper valve on the airbox to adjust the volume to suit the rpm. There is definitely a tuned 'sweet spot' and my guess is that point is somewhat more voluminous than would fit/look good on an XB. My point? None really I guess, drilling works. But maybe instead of going hog wild venting the thing, perhaps just two 1-inch holes would do the same. Instead of letting more air IN we need to let the negative pulses OUT so they don't reflect off the lid and back into the throttle body. Maybe that 12 airbox lid cone helps more because it diffuses this intake pulse rather than smooth the air going in. Or this is all a result of the martini's my wife made us because we're bored watching the Olympics opening ceremonies (they're on really, between all the damn commercials). | ||

light.. I did'nt go nuts w/ the holes.. I only put a few 9/16" holes in the left side probably 8 or so, and two in the front. I tried to leave the most direct flow pattern from the ram air in tact. Whatever it did, it DID. I can honestly say my bike has more response and the wheel came up with ease for the first time.... | ||

I drilled about 13 holes, total area a bit more than half the throttle body (XB12). There's 5 holes on the opposite side that you can't see.  Definitely feels better but I won't know how good till I go for a good run. The front came up in a part of the road where it never has before, but maybe I was trying harder. Very windy today so not real good riding weather. Couldn't hear any extra airbox noise except a little at 3700-3800 where it's always a bit loud. Very good 1st impressions and looking forward to the hills again. Definitely stronger down low around 3000 rpm. | ||

See I told ya'll.  | ||
| Opto |
Yeah thanks mate, now if I can just gather enough motivation to finish the Megasquirt FI, between that and a drilled airbox and the Drummer things might get real smooth. | ||
| Hogs |
We might all have to re look at all these ehxaust claims now , since this new drilled airbox deal, all the exhaust claims MAY change some for the better and maybe some for the worst, and some don`t do anything......I wd. think drilling holes,slots, etc, IS not the total answer YET... Some kind of new air entry,either through scoops,down low pickups,and under the tank cover just an open K&N air filter all around while using the 12 airbox dimple on top maybe a good starting point... | ||
| Tatsu |
Hey for those of you using the Drummer.. did you remove the servo motor and padding that was holding the motor in place? I wanna try the airbox drilling and I like Opto's method, but that servo motor pad is in the way. | ||
| Darthane |
Depends on what ECM you're using. If Race, remove, if not, you either need to leave the servo or build something like Opto did to mimic it so that you don't end up with the trouble light on all the time. | ||
| Tatsu |
I'm running the race ecm, so I can remove it. Any problems with water collecting there? Sorry I haven't pulled out the form to see if there is a draining hole. | ||

just got back from a little riding before the rain hits, I don't know if its related, but I noticed the engine ran much smoother around town than normal. This is the only physical change I done to the bike. Everything else is stock.(And yes there is an increased in sound from the airbox cover) It is cool out today, and a lot less humid than has been lately. But it was MUCH smoother ( 25 - 35 mph range, 2nd gear) | ||
| Shawn_9r |
OK, I know this has been gone over many times (can't find the tread)... has any one "DEWALTED" a stock 9 box with NO other performance mods and if so was there any difference? I am trying every}thing to avoid mowing the lawn and that sounds like a good way to get out of it. | ||
| Glitch |
Drill 'er box Shawn! She'll love ya for it! She'll spin up faster, and she'll be louder too. How can you resist? | ||
| Shawn_9r |
I can't... the drill is already out. Thanks! | ||

Ok Guys, I got back on the Dyno today with the Buell Race Can on the bike. For those who have not been following this thread, last week I Dyno'ed my '03 XB9R w/Race ECM, Race Air Filter, D&D Exhaust and a 12 Air Box that had been drilled for better air flow (see earlier in this therad for pics). After doing the Dyno runs with the D&D Exhaust, I got to wondering how the Buell race can would compare. Since I have both, I put it on this week and did some more Dyno runs today. Below is a scan of the chart from today, it shows both the best run with the D&D last week (red lines), and the best run with the Race can today (blue lines).  If it's hard to see, the overall numbers are: D&D 74.8 HP, 64.1 ft/lbs Torque Race Can 79.7 HP, 65.6 ft/lbs Torque While the Race can makes more power down low (below 3800 RPM) and on top (above 5200 RPM), the D&D is stronger in the middle. More importantly, it shows that the power comes on sooner with the D&D (by 500 RPM), and that while the Race can shows up later in the RPM range, it does surpass the D&D at 5200 RPM and for the remainder of the RPM range. Another difference is that the D&D is roughly twice as loud as the Race can, to my ear anyway. The guys at Bennetts love the sound of the D&D. My neighbors are less enthusiastic about it, especially since I leave for work at 5:30 am every weekday. Both pipes feel great with the drilled 12 airbox, and it does make a noticable, verifiable difference over a non drilled 9 airbox. Put it this way, even though I love the feel of this bike, when I did my first set of Dyno runs with this bike (Race ECM, Filter, stock 9 airbox and D&D exhaust) at 67.4 HP and 59.1 ft/lbs, I was a little disappointed it wasn't more, but figured it's a light bike and it does feel great. Now that it has 79.7 HP and 65.6 ft/lbs I'm pretty stoked! Cause the bike feels just that much better!! Oh, and Opto was wondering how it would perform with the outer cover on, since I did my runs last week with the outer cover off. I ran it both ways today and it made slightly more power with the cover on every time. Go figure. Timbo |
