'09 Busa-How much Horsepower should it have ?

[Blanca BusaLess]

Actually hooked up to the dyno only twice but both times they worked her thru the gears and in various other ways but there were several runs made each time before and after. It was neat to see the gain same day same machine.

Now I'm curious about the xtre..........**** it never ends......can't just own it......pushing midnight here..........she's calling to me...........I never believed guns talked to people and made them go postal but I would believe it if someone told me their busa called them out for a midnight ride............honey do you need anything from walgreens ?.........I'll go...right now.....back in a jiffy..........no...no...no...its because I love you not her.......

Anyway back to reality. Is it not possible to on the dyno make a map for each gear and program that into some little doozamawhicky ? Forgive me because I grew up with two shocks on the outside instead of one under you but since I did not ask and after reading link led to by Got Busa I wonder what gear my bike thinks its in all the time ? I will run it thru 3 or 4 tanks to see if I notice fuel mileage loss or gain but I assume since I picked up the power the mileage will go. Before I was getting about 35-40 mpg. We will see now. I don't care about taking off top speed limiter. But I am curious if cool and on same dyno what numbers it would show with/without xtre on it. If after having bike dyno tuned you take off xtre it affects the custom map in bike made for all components installed at time of tune , correct ? After removing xtre you would have to retune on dyno again , correct ?

Oh my head hurts....I got Busa-on-da-brain ! SSSSSShh...what was that....did you hear that......it sounded like.........no it could'nt be..they don't talk or have souls do they....???

Read the thread on ecu reflashing. A lot of the things the tre does can be handled with this. Smithabusa is a very knowledgable guy that will help you and his site has a lot of info on it.

Still seems like whether or not you drink from a green bottle or a brown one....to each his own. I find just as many good comments on xtre as I do bad ones. Still no real solid proof that xtre does or does not work. All I know is its on my bike now and it runs like a demon. I guess maybe it would have been nice if possible to just do header and pwr cmndr then dyno then add xtre then dyno and compare..Also would have needed a 20 min ride before xtre for seat-o-pants figure gathering..

 

[m_ridgeway]

Hpc added a bazzaz z-bomb with no gain. Basically the same as the tre. But like you said a lot of opinions out there. Personally I won't be using one but I don't see what it hurts if its already on there.

1.5ozs of weight....Durn now she weighs 2 tons 589lbs and 1.5 ozs !

Ok do you think I can walk past the sleeping Cuban goddess in this room and go sit on my Japanese mistress for a while. Shes cold I know it......Let me get a blanket for her !
I call the wife a goddess because she is a latin beauty as well as being a very understanding person. Not many wives would with only a days talk say ok whatever makes you happy and let you go buy a "Death Muhchine" (said with a Cuban accent mang')

Look in a few of the LSR threads or discussion threads that people got upset about. The TRE has been proven JUNK on a Gen-II bike.

Whenever you are ready, come on down to TEXAS! I'd be happy to help you get setup to make a few runs at a 1-mile event...

If the bike runs great and the A/F numbers are inline, don't worry about the peak numbers. Just because a bike makes more PEAK power on a dyno doesn't mean it's going to be faster on the track.

I so agree with the last statement...we ride outside in a total different condition than what your dyno readings came from...I did this for a customer one day at the shop I built him a peak power map then a map for street strip conditions.We rode out through some back roads,out on some straight aways then to track,made passes,switched maps,made more passes rode back out those same earlier roads to his surprise he saw the difference...A DYNO IS A TUNING TOOL NOT THE GOOD ALL ANSWER...

I too have question my sanity the first time Gray Matter ,O0PS im sorry, thats my bike name ,thats what she likes to be call ,but u are fine they talk and cry they have feeling my loves going to the doctor ,doctor Greg and nurse Terra threat her so good. So your fine its ok your not alone man your not alone

 

[NOW_WHT]

Btw I can make a dyno show 2000rwhp I know the devils in the details and every one esp diff brands read very differently.

No need to reply to my previous post. I quit you. You'll just bable on and on. Have a nice existence.

How many bikes have you built? How many physics classes have you taken? How fast was the tail wind when you went 204? No I haven't read or seen your build. And your math problem doesn't account for gearing, enviro factors, or a lot of numerous other things. So your bike only has a 5-6 percent loss through drivetrain?

which puts you at 180. Then your saying you gained another 20 with the same loss that would really mean you gained more than 20hp.

The Physics supports the dyno numbers, not discredits them. I ran an eddycurrent brake dyno for GM in my undergrad days, so I know a bit about dynos. What I'm saying is that iIf you compare the claimed numbers on an inertial dyno, they come very close to the emperically derived quarter mile trap speed calculator, and they are dead on with terminal trap speed calculations for aero drag >>the Gen II tuned correctly is good for 200 HP Yes, the calculations very carefully take into account gearing and rev limit, as well as air density, etc. I have forwarded several physics calculators for the Busa and ZX14 to anyone interested on this forum on request. If you want to debate physics and the limitations of the calculations, we can do that: yes, I know a little bit of physiscs. The forum is supposed to be about information sharing. Let me know if your interested

Ok , I know this is a WFO topic but my question is :
How much horsepower should a Gen II Busa have ?
In particular MINE ! 2009 Busa . I put Muzzy slip ons and a K&N
filter. It seemed like it wasn't running right after that. A little surging.
My guess was that the bike just wanted to be free and have a proper
parts mod and a good dyno tune. So I purchased a 4into1 Muzzy stainless header for her. Reason I stayed with the Muzzy is because it allowed me to use the can and only have to buy header and midpipe.
I purchased a Power commander V, Healtech XTRE as well as Schnitz block off plates . So off I went to the local speed shop which came highly recommended by word of mouth as well as internet chatter.
Upon arrival we did a baseline pull and then the mods and another series of runs while tuning followed by a final set of figure gathering runs. Machine used is I believe Dynojet 250i.

STOCK NUMBERS WERE :
MAX HP 164.64
MAX TORQUE 97.08

AFTER MODS :
MAX HP 182.25
MAX TORQUE 104.95

I live in south Fl. at sea level. I always get confused as to whether you make more or less here ? I am curious about the figures because all the numbers I see for others are higher. I have even seen article by 'Got-Busa" where his made 180 out of the crate ? I have seen some in the high 190s after the same mods just maybe a different pipe. I figured XTRE would make a HP diff ?
The throttle feels so much lighter now. The bike revs so much quicker now. It is the way an American Jap bike should be ! An opened up dyno tuned monster.
Now granted I did gain almost 18hp which is a respectable number and seat of the pants feel is definitely different. On a Hayabusa will I miss the loss of a few ponies on top ? Not around here but I still wonder
where ya'll think she should be or if this is respectable for sea level in SoFla ?

I have posted dyno runs below.

OPINIONS ????

They must have used fairy dust, and some dyno trickery to get you 18hp out of just a pipe. They most likely fudged you a nice low baseline...then got you the typical gen2 full exhaust numbers. That way they "blow" you away with their incredible gains....and keep you and everybody else who hears about it coming back for more lol. You're baseline stock run was way low, but your numbers after the pipe are pretty typical. Just ride her and enjoy

You keep telling people to click your signature, for what. All you did was copy what Brock, Dave O and Lee worked on for two days at Maxton in order to get the Suzuki sponsored bike over 200. It did not happen on the first day either with a few riders trying. I was there watching. Those guys are all pretty darn smart and the team came up with the trick. Should people not be clicking on their signatures not yours, thats my problem with you. Unless you built another bike you have really done nothing but copy cat, but you act like you invented the Hayabusa.

Hats off to Johnny Cheese for a great tune I know he did something. Try tuning your own bike next time. Do it all yourself with no guidance then come talk to us. We don't go over 205 the first time out ever on our 1441 and you are all over the web bragging how your bike is so much faster...blah blah......now thats some funny stuff. I am pretty certain everyone would rather have the bike I built, not some cookie cutter project anyone with the ability to read could do. So there you have it..........thats why I can't stand you and laughed in your face at Texas. You keep PM' ing members that I don't treat people right, respect is earned not given. Copy cats and cheaters get none.

Yea I'm interested in learning.

Let's start.

How much hp is the gen 2 rated for?

What is the loss through drivetrain trhough wheels. I would say its at leats 10 percent.

That puts you at 171.

How are you adding 33 plus fwhp which would equal about 30 at the wheel if we use the same loss.

[m_ridgeway]

I'm assuming rated hp at 190 at the crank.

[GPW]

That has been a question of mine all along. How do we do better than at the crank HP with a drivetrain loss 10-17%-20% with bolt-ons...the Busa I just finished made 185 SAE 189 STD with MR9, I am pretty certain it will run 200. To be sure, I am bringing it with me to Texas. I will ride it at 222lbs dressed and see what the result is. Based on the dyno results of 2fast's Alien Head piped bike with supplied map and tweaked map and MR9 I am certain that we are not out powered by any HP. We are actually stronger everywhere in the powerband not just peak power. Factual results witnessed by Kevin himself.

 

[m_ridgeway]

I probably won't be able to make if I do I won't be able to race. But I'm thinking of going just to watch and learn and then compete once I understand a lil more about what its all about. Might bring my car see if shell do do the factory rated 150. Lol. I doubt it'll break 135.

Shouldve cranked up the correction factors. Then you couldve had limitless gains.

Lmao. Google johnny rice. He has a video where he draws a dyno sheet that shows vtac kicking in on his honda. Vids like 4 y/o and still cracks me up.

I wish I had made a copy of my bike's certificate of origin, but rounded to the nearest horse it stated 195 horsepower. I'm pretty sure it was 194.7

Where did you get that? I never seen one before. I bought mine new btw. My buddy didn't get one when he bought his new from a diff dealership either.

I bought mine new, but it was from an out of state dealer. I had to bring the certificate of origin back to my local tag & title office to get the official state title made up and for registration.
