I knowods are listed in profiles, but HP is not. Can you guys post your performance mods and gained HP? Just looking for what mods give what gains- thanks! | ||
| Augustus74 |
Hard to tell unless you dyno the bike, which many people don't. Some companies list the gains on their websites but those bikes are prob. tuned for those mods.  | ||
| Nillaice |
filter, ecm, and exhaust will get you the most bang for yer buck. but there's always big bore kits, port& polish, stroking, turbos and nitrous. .... most of us don't have dyno's | ||

Yo dawg, i gotz this chip on ebay yo, it sez I will get 50 more hp. gots to be real, they cant lie bout that shiz | ||
| Too_tall_ss |
 +25 hp right there.... (it's got so much energy in it, it sweats) | ||

These engines are near the limits of reliability already.Significant mods (in my opinion) equal a grenade motor. 93hp 100 lbs. ft. torque is what my '87 XL dynoed at. I remachined my cases to accept a 3.625 diameter bore cylinders and stroked it to 4.3125.I added Branch heads,Amtec roller rockers,Andrews .490 lift cams,10.5:1 forged pistons,Dyna coils,single fire MSD ignition. Everything south of the crank output shaft later would break. I shorted statorS.Sheared the splines off of the final drive sprocket,broke the mainshaft transmission clutch gear.It WAS powerful,but unreliable. My expectations of both my XL based Buells are more realistic now.They're BONE stock.I bought a moe suitably OVERENGINEERED machine of another make to modify.And with geat results too. If your Buell doesn't deliver enough power,add a make that does. Own the corners (Message edited by ducxl on July 23, 2009) | ||

Why not list suspension/handling mods? They play a MUCH BIGGER role in making the bike quicker unless you're only talking quarter mile or bonneville/dry lakes. | ||

OP asked for horsepower ratings not speed. Also if you've never seen his bike-it's more of a badass street machine kinda bike. (Message edited by Augustus74 on July 23, 2009) | ||

Slaughter is putting down some wisdom so soak it up while you can. If you put your dollars in the suspenders you will see a huge difference in your ability to ride the twisty's faster. Over the years I've had some heavily breathed upon big twins that were lots of fun, but not the most reliable of machines (and really expensive when you grenade the engine. | ||

Based on a XB9, these numbers are from various websites F.A.S.T. air intake system possible 6 HP Performance exhaust possible 4-7 HP Race ECM/Map possible 2-5 HP The largest HP gains for a Buell motor come from displacement, example the XBRR is a 1340cc motor and makes in the range of 150+ horsepower. There are not many HP numbers listed for individual parts such as cam's and port work. The overall horsepower gain with the most popular mods is about 12-15HP, in a number of cases, torque improves much more than horsepower. With the mods your bike has, it is about as good as it will get without doing something like nitrous a turbo, blower or more displacement or a combination there of. The stock Buell motors are already hot rodded significantly compared to it's Harley brothers. | ||

Why not list suspension/handling mods? Cause I ain't got any. Other than the Buell Race Kit, I got nothing but stock components. I did however have a suspension guru help me set up my bike. Let me tell ya what! It's like a whole new bike. I'm tellin ya. Unless you need to be heard, leave the power to the Buell engineers, tune your suspension, and take a class like Ed Bargy's http://www.edbargyracingschool.com/ You'll enjoy the ride more, embarrass a few, and have a really reliable bike. Unless of course you're more into having a "bad ass" bike, and not into riding as much as you possibly can. There's no shame in that. I see bikes all the time that are real nice tricked out bikes with very low mileage. It's all in why you have a bike, and why you ride. I don't care what you ride. I don't care if you can keep up. I don't care if I can keep up. I ride, and ride as well as I can, and I enjoy every moment I get to ride. I love to ride. And because I love to ride the twisties, a reliable excellent handling bike is all I need, not to mention that VTwin grunt sure is fun in the mountains! | ||

I love to ride, too! I put 1000 miles on it last week just riding it around with no agenda or destination. If I have a choice to ride or do anything else- I'll ride badass or bone stock- riding is riding. I bought my bike with all the mods already in place and not really knowing what I got into. I've been playing catchup here and unfortunately am learning as I go (mostly with the help from you guys) I am just trying to understand exactly what my bike has and how I can fix what's broke while exploiting what's not broke. I love everything about my bike and the only thing I'm trying to do is get rid of the PC 3 on it. This wasn't meant to be a d!ck measuring contest- the origional post was to show my dad what our bikes are capible of with a few mods. Not knowing EXACTLY what I have, I turned to the pros on the subject- YOU GUYS!!!! I thought that if you do work to your bike, you would be proud to show off what you've done. In doing so, I would benefit by getting my dad off of BMW sportbikes an onto a real bike- BUELL | ||
| 12rrrrrr |
what mods do you currently have? then maybe someone can give an informed idea of the hp gain (when setup properly) | ||
| Srwitt |
I've got no mods, factory suspension settings. I'm 6'1 165#, and when it comes to my buddys on their rice rockets, I do own the corners, against most of them anyways. Anybody twist the right wrist and haul ass in a straight line. Suspension tuning will be the first thing on my list of mods, but I'm farely happy with it currently, so its not a must do item for me. Jakecheez, read up on the PC3's with our bikes. The general consensus is that they are worthless. The only worthwhile method of fuel/ignition mapping is ECMspy or some other method of directly modifying the fuel/spark tables within the ECM. Edit- Mr Cheez, just reread your post, is it really that hard to remove a PC3? I thought they were a plug n play sorta deal. (Message edited by SRWitt on July 29, 2009) | ||

(I thought that if you do work to your bike, you would be proud to show off what you've done. In doing so, I would benefit by getting my dad off of BMW sportbikes an onto a real bike- BUELL) Does it really matter what your dad rides? For me it is just the fact that I can still ride with him, It is coming to an end due to some health issues and I am going to miss riding with him. | ||
| Shifty |
Agreed. My dad rides a BMW and I love to ride with him for who he is, not what he rides. Then again, I can't stand it when he rides his Goldwing because I swear he maxes out a t 25mph. | ||

The old man rides a 2001 Yamaha Venture. Some days I have to stop and wait, other times he rides like a mad man and never falls far behind. The visiting and beers after the ride are the most enjoyable as we still bench race at the end of the day. | ||

My dad rides a '93 FXD with a raked WG frontend. Talk about not keeping up in the corners! Lol | ||
| Ferrisbuellersdayoff |
My old man has a bone stock `51 Panhead, and I have never gotten away from him. It kinda aggravates me, but at the same time I'm proud of that machine, and the fact the man operating it is my dad. His Shovelhead on the other hand. I sit and wait for the straight pipes to announce his approach before I start up again. | ||

100 rwhp 86ftlbs of torque 2003 XB9 with extensive head work, a modified X1 crank, open air box, jardine exhaust, chain conversion, catch can, etc. (MOST motor work done by Hal's in WI) dyno sheets for some modified bikes including mine are posted in the knowledge vault show us your power board. All the gory details on my bike are here. http://www.badweatherbikers.com/cgibin/discus/show .cgi?tpc=3842&post=519178#POST519178 | ||

To me, the best motor mod is the Dummer exhaust because it really flattens out the torque curve, and makes the bike very easy to ride at any speed. The more you work on your suspension, and understanding of how it works, the faster you will go. I was fortunate in being able to find some good deals on Ohlins units, and they really make a big difference. Just adding the competition springs and re-valving the shocks can make a world of difference too. Tires are critically important, and are improving all the time. I am really loving my Michelin Pilot Road 2 dual compound tires, and they just seem to keep getting better upto about five hundred miles, or so it seems. For track day riders, the Michelin Pilot Power 2cts have been well reviewed as well. Lastest products from Pirelli, Dunlop, Metzler are all good too. I agree with the many brothers who warn against modifying the Buell motor for street use. The bike will hold its own in the twisties against any bike, and if you need to do stand up wheelies at a 120 to keep up with your friends, then you either need a different bike, different friends, or preferably both. jes' sayin'  | ||

I find something very interesting. Most everyone has this obsession with...horse power. And very few mention torque....and worst yet, I've seen no one even mention driveability (excuse me...rideability). In tuning both my XB and my 1125, I did/am doing things that not only enhance the overall power...but ALSO, to enhance...how they run at lower speeds. Since I drive the Los Angeles (and surrounding areas) freeways and roads, I need to know that when I wack the throttle at lower speeds...that the engine and chassis will do what I ask. It's like when I port cylinder heads...porting for max lift "only" is ridiculous. The valve is only there for a split second (even at idle!), the valve spends a lot of time going thru its mid range of lift. Porting for max lift is easy, finding good flow at mid lift...takes time and effort. Just like tuning the engine the heads are going on..! Just my take on things. Mike | ||
| Fast1075 |
Looks like someone has a good understanding of flow dynamics....reminds me of a true story....there was a Suzuki GS1150 cylinder head that made the rounds from owner to owner usually from E-bay sales...it was a fake "proStock" head that was SUPPOSED to have been done by a major porter...it was a good fake, right down to a fake badge attached... That POS would flow some major numbers at full lift...but wouldn't make enough power to pull a greasy string out of a cat's butt. The moral of the story is choose your mods carefully. | ||
| Od54 |
I know I'd like to move both my curves up all across the RPM range. It doesn't mean I'll use the top end to do some huge wheel stand at insane speeds, but that kind of power can be a by-product of getting some more low end. Horsepower isn't just for top speed, lets face it, we run out of revs first. I've got a hotrod with more top end power than I can use. It just came along with all that other power than I can use. | ||
| Jakecheez |
great, thanks guys! for the most part, you guys are extremely helpful. not this time! 1. i dont give a flying FU[K what me dad rides. yes i love riding with him, yes he rides a sportster and a bmw. 2. i asked you for horsepower to mods. looking at cost effectiveness to bump hp. 3. if i wanted info about rideability or tq, id have named the post (mods=rideability) or (mods=tq) you guys are rediculous. i asked a regular question and got made fun of, bashed, redirected, and ignored the whole way along. thanks for being pricks about it- | ||
| Fast1075 |
Jake...I think if you look real hard...there are some valuable tidbits in this thread...at least one direct answer..so there are some goofball answers...if you had listed all the mods you have in the original post instead of making everybody look at your profile page it would be easier...Brian even posted a link to his dyno sheets...  | ||
| Jakecheez |
fast- i get it, there are some good and helpfull things in this thread. i just have to wade through so much unnecessary bull$hit that the whole thing reeks of it. and why would i have to list my own mods? i was asking for YOUR mods/HP gains. thats it. i found what i was looking for in an issue of super sportbike. | ||
| Froggy |
Problem is, many mods individually do not affect things enough to show up clearly on a dyno. A K&N filter will improve airflow, and might show a HP or two on the dyno, but that could also be within margin of error with the dyno. Also what works great on one bike might not work great on another because something else is different. I don't know what else you could do to your bike for more power without doing something crazy and expensive like a turbo or nitrous system. The sky is the limit with what you want to do to your bike, your best bet is getting in touch with Pammy at Cycleramma, she can help you with whatever you want. | ||

100 rwhp 88ftlbs of torque max 2005 XB9 with head work and other mods. not done with it yet. like dilablobrian bike it takes a lot of time to get it there. but a xb9 can be made to anything you like. plus side it has lower cost insurance!!!! cheap fast upgrade for a xb9 is a xb12 crank then port the heads and get the xb12 ecm data. tune from there. that can get you in the low 100+ hp upper 80"s tq. mike | ||

Actually Jake, your statement was that you would benifit by getting your dad off the BMW. You did kinda ask for it. |
