200+

[DXB]

200+mph can be acheived with a stock Busa just about..

How much power do you need to do 210, 220 and even 230mph +??/

[zrxdean]

Most stockish Busas run mid-180s. It ain't as easy as you might think.

There are calculators that can predict how much more power is needed given current known values. To go faster you need exponentially more power.

Thanks for the link, but ive found calculators in the past to be innaccurate, i am after proven top speeds with X-amount of power etc?!

There must be some board members who can shed some light.


Most UK Busa's ive heard do late 190's standard, some just touch 200... Mid 180's sounds a little low.

It's the variables that make the calculators inaccurate.   Every bike is different, every tuck is different, traction, air density, humidity, rider weight.  ETC.   Your best bet is to test your own bike with you on it.  Let us know your results.   

I know I was using about 280-300hp just to go 217,  Many have gone faster with much less power, in much less distance I'm sure.  Put a good rider on my bike and you'll have more mph with no doubt.  Just too many variables

It's a well known fact that the shipment of motorcycles across the ocean to the United States causes a phenomonen know as Salt Waterosis. This results in said motorcycle gaining several pounds over what the Manufactuer says it weighs and losing several HP over what they claim.
It's also a given that the high concentrations on Nitrous in the UK air make British Bikes faster.
I have yet to encounter the 200MPH stock Busa, much less 190mph.
You know I thought all Busa's ran 200mph until I tried it. My stock '04 with slip ons ran 178MPH.
With Full Brock's system, P.A.I.R. block off's, small airbox mod, Better ram air tube seals, Power Commander, synthetic oil, running fuel and I weigh 110lbs I've run a best of 192MPH in the standing mile. Now it would probably run faster with an unlimited length to top it out but the mile certificate is what I have.
The accepted # I hear the most is 200HP= 200MPH.
I think my first Dyno run showed 154WHP I ran 182mph with that setup. Believe me it's alot harder than just adding a few mods and going 210MPH.
My advice to you is if you want to go that fast get involved with one of the LSR events Texas Mile. Loring, Maxton, ElMirage, Bonneville whatever the UK has, prep your bike enter and see what you REALLY can do, NOT what you think. Then get involved in some of the LSR boards and get some help from people who are out there doing these kinds of speeds.
It's pretty easy to run 180MPH but from there every MPH comes at a price. I've been on the phone with my Sponsors for a year on and off just to get that 192mph certificate. Do some research on LSR on the Busa Boards and you'll find a wealth of knowledge and a ton of people willing to help you out. I would have never gotten this far without board members help!

I got 300 HP on pump fuel and I start to run out of HP around 220 with 20/40 gearing. I am pretty sure I could hit 236 and I am up at 7000 feet, but the RPM gauge is slowing down around 220.

Its definetly not as easy as you would think... I find it hard to beleive any stock busa could pull 200 MPH. THere has been rumors and here say about it, but I just find it hard to beleive.

[SRADkneedragger]

Some more food for thought. SRAD told me that years ago when he started roadracing He bought like 10 YSR50's and started matching all of the best parts to build one motor. ie find the intake and reed cage that match the best, find the shortest cylinder and the engine cases with the shortest deck height, best crank, I think you get the idea.
Factories do the exact same thing when they roll out a new Model for the press or build a bike for SS Racing. They hand pick the best of the best parts to build an engine that will perform at it's peak as a "stock" motor. The longest rods, the shortest cylinders and the shortest head = more compression. The straightest crank means less rotational drag, etc etc . I think the first Busa's were probably done this way and that is why they were so fast add to that the raging HP wars.

I dont yet have a Busa, but id expect after 10 years of this monstrous bike that there would be some Top speeds already attained by people.

May I ask, 217mph indicated or genuine GPS verified?

Hi Marie,

thank you very much for your input into this thread. I unfortunately as mentioned above do not own a Busa, but would like to one day and am just genuinely interested hence the post.

May I ask what the LSR board is?

I will ask my friend, he tested his Busa at UK's Bruntingthorpe Proving grounds so he has an accurate GPS recorded time, I know it was under 200mph but i will check exactly.

Another UK magazine tested a press bike which did a gen 200.2mph.

I got 300 HP on pump fuel and I start to run out of HP around 220 with 20/40 gearing. I am pretty sure I could hit 236 and I am up at 7000 feet, but the RPM gauge is slowing down around 220.

Its definetly not as easy as you would think... I find it hard to beleive any stock busa could pull 200 MPH. THere has been rumors and here say about it, but I just find it hard to beleive.

May I ask you also, GPS verified 220 or Indicated? Speedos go to 220mph right, so a Gen 220 the Busa would show (if clock could show) a good 235+ as the Speedo is pretty innacurate at high speed.

[joea]

when you find one of the 200 mph stock busas, buy it..............

many come to bonneville each year.........most run
170's...and a few mid 180's.......thats real world, verifiable...certified....not
an article....heresay...etc........

[fvance]

I went to Bonneville last year with a mildly modified 07 busa, dynoed 168hp, most box stockers are around 145hp on the same dyno. I ran192+.  Fred

[Jonny Hotnuts]

A friend of mine was on a testing group in 89 or 99 on the busa and he told me that it a stock "pre production" 99 was able to go 200.

BUT.....

It was in a group of 5 other bikes and made the 200 mph speed only for a few seconds when drafting. It was their intent to say the bike was able to go 200 for marketing.

I dont know how accurate his statements were nor now well I remember the conversation.

I only know that he raced for a Suzy factory team and was in fact part of the testing team
(from what I remember I think he mentioned the testing was done at daytona)

Most likely would have happened in 98 or 99...

I took Michelles 2001 stock Busa to El Mirage and ran 187mph on the first and only pass I ever made on it, it was restricted and I am sure it would have gone a little faster it it had not been.

I have see stock Busa's run nearly 200 mph however most run 180's or so..

While it's a different scenario, my situation is still good for contemplation and comparison. I have 287 hp to the tire and BARELY got 200 out of the bike at Texas. I'm a big guy (6'2" 210) and my tuck SUCKED. I can vouch for the fact that it's a lot harder to go fast than most people think. Assume you will go slower and maybe you'll be pleasantly surprised.

[Jonny Hotnuts]

Dont beat yourself up, the fact is that it REQUIRES more HP to go 200 at maxton or texas then B-Ville.

B-Ville has a lower air density then Max or Ta-hos.....good for turbos, bad for NA.

Measured by East Coast Timing Association in 132' at the end of a standing mile.    Sept 08'
www.ecta-lsr.com

It would seem that the log run is not working at this time.  if/when it does   Bike # 9398

My last two sunday runs were done within an hour and 5 min of each other , and came out within 1mph I think. top was 217.861???  I'll blame the poor speed on Boost control ramp, and gearing not being proper for the power.

[Got-Busa?]

See sig for a Gen-II but the weather got me there....

[DXB]

These 280HP GSXR1300's which run mid 8's at over 160mph,

what do they do 0-60 and 0-100mph?

[halvefast]

See sig for a Gen-II but the weather got me there....

Yep Got-Busa is one of the very few who has attained the 200 on a stocker,
yes it was favorable weather for the 204 number,
but he was kicking the door in during much worse weather too! 

Just to add some numbers for you to ponder with here is what it took for me to reach 200:
My total weight package was 760 with 225hp (on dope) ran 200.2?? into 5mph headwinds,
next event we had 15mph head/side winds with 241hp made 4 passes over 200 best of 202.577
same set-up more juice, would have had more speed with a gearing change.

[Kiwi]

These 280HP GSXR1300's which run mid 8's at over 160mph,

what do they do 0-60 and 0-100mph?

I don't think anyone measures these numbers. But I have run 8.8 @ 158mph. All motor, stock wheelbase. That engine was making around 225hp. It also went 204mph in a flying 1/4. It was doing 5.8s @ 130mph in the 1/8. As far as top speed goes you also have to remember there are certain factors which will effect the result. I don't think any of the venues allow for the ultimate numbers. Bonneville will have traction and altitude to slow you down. Maxton is only a 1 mile run up, etc. But when it is all said and done, the Busa is the fastest bike available in a straight line, and the easiest to make even faster.

[HOS]

DXB hello mate 

You need to check out with the guys who do the top speed runs in the UK like 200mph.org or UKBusas.co.uk ok ?

There are NO definitive figures like the ones you are asking for because there are so many variables 

Rider weight is a major variable.
Air temp, air density, humidity, air quality, air movement etc are all major factors at these high speeds. Thats just "air" !

I believe a stock but well set up Busa has hit 200mph in the UK.
The Flying Dutchman hit 265 mph last year or the year before.

Pay attention at the back there !! 
http://www.suzukihayabusa.org/forum/index.php?topic=129549.220

0 to 60 times are pretty irrelevant tbh unless your on the track and most are looking at distance times over yards and not times to certain speeds.
0 to 60 times are more about how strong your forearms, your back and your grip strength is than power of the bike 
On a stocker your looking at 2.5 secs or there about 0 to 60.... but only if your strong enough and have the right technique and the balls.
The "launch" is critical and it isn't easy to launch them quickly 

[HOS]

DXB, to give you a feel of the acceleration and I appreciate you would like a Busa, so please enjoy these two videos 

1st one a tanks eye view on a stock Busa, front wheel comes up so easy  The speedo is mph not kph OK ?

http://www.youtube.com/watch?v=FfGK4gQdaZA

2nd one is a sweet turbo Busa, watch how fast the speedo needle rises and how fast you run out of road ?
At the 12 o-clock position on the speedo, thats about 120 mph.
Trouble with Busas is everything else is just in the bloody way !!!!

One of the biggest things to consider speaking as a rider who's done over 180 is the wind pressure on YOU ?
You need a strong neck  !
The hammering you get above 130 gets worse above 150 and above that its getting savage.
At really high speeds your head is almost rattling or vibrating to the point of your vision becomes blurred.

The Busa aerodynamics do`nt really work well until your over 130 and then its getting hard on your neck for long periods of
sustained high speed.

Other factors at that speed are what happens if something solid hits you or the bike? Or if your front wheel hits something more than small pebble ?
I have mates who been downed at high speed by birds hitting them or the bike. One time a mate got hit in his right hand by a bird while he was doing 120.  

[Jonny Hotnuts]

Rider weight is a major variable

Dude not to be a dick but weight almost has no effect on top speed....unless your added weight ALSO means added girth.
The weight alone only has a small effect due to increased rolling resistance due to tire deformation and increased load on the wheel bearings. For an example 2 identical cars with the same motor one weighs 1000 pounds, the other 2000. If the 1000 pound car can go 200 mph the 2000 pound car will only loose about 3 mph.

This is not the case in drag racing....or racing where you have a limited space to reach your top speed.

The Busa aerodynamics do`nt really work well until your over 130 and then its getting hard on your neck for long periods of
sustained high speed.

Cant really say I recommend driving at high speed for sustained periods of time....but each to their own.
I can say that for high speeds you should be at full tuck with as much of your head behind the windscreen as you can get.

Good luck

[bulletb]

It CAN really happen- 200+ if the weather's right!...I know I did it!

GenII w/pipe & pcIII,gps derestricted...all stock motor! Cheese tuned.

But a "Mile" is not really a far distance....when your haulin ass! it's less than 20 seconds for the entire run!

Lightweight guys tend to have less frontal area compared to heavyweight guys and they can also tuck in better.

Losing 3 or 4mph due to a heavyweight rider can be all the difference.
