Busa Engine

[Karlo]

What Is The Suzuki Hayabusa?

The Suzuki GSX1300R, also known as the Hayabusa, is a hypersport motorcycle introduced by Suzuki in 1999. It has a 1299 cc inline-4 engine rated 175 bhp, and a 6-speed sequential constant-mesh gearbox. The Suzuki Hayabusa is consistently tested as the fastest production motorcycle in the world.

The Hayabusa engine can be modified with turbochargers, and turbocharged Hayabusas hold many top speed and acceleration records, including the Fédération Internationale de Motocyclisme 1350cc world record of 252.832 mph (406.894 km/h), the fastest American Motorcyclist Association U.S. record for an open wheel bike.

As compared to a traditional automobile engine, these two power plants have very different driving characteristics in terms of both delivery and handling. By their very nature superbike engines are considerably smaller and lighter than car engines, therefore reducing the overall weight of the car and allowing a high power to weight ratio, which in turn produces rapid acceleration and impressive levels of agility through the corners.

To produce a high specific output from just 1.3-litres, the Hayabusa engine has to rev much higher than a car engine. Maximum power is reached at a heady 9800rpm. Car engines have more torque low down on the rev range making them easier to drive around town and more comfortable when touring. Superbike engine cars deliver their biggest thrills when being driven flat out - when they are fast, frenetic and uncompromising.

For that reason superbike engine cars are more suited to the track than the road. On the track, their sequential gearboxes add another dimension to the performance of the car. Using the superbike gearbox and clutch at slow speeds on the road does take a little getting used to as it's action is not as smooth and easy as that of car engines. Due to their design, the life expectancy of a superbike unit is shorter than that of a car, but they offer huge performance at a low price.

Not having any bike engine experience, I was searching for information on how to get power to the wheels with a bike engine.

Here are some pics that help.

More pics. The Blue box is reverse which is activated with a lever inside the cabin.

What about the Torque output Karlo?

[Karlo]

105 TQ with mild mod.

Qaife makes several differentials that can be used with the Hayabusa, from simple chain-driven limited slip differentials to units that connect directly to the output shaft of the Busa motor and include a reverse lever.

Bike engines are wonderful until you realise its a bike engine! Have to rev them all the time, change gears all the time, overtaking on a highway requires changing down 2 or 3 gears and lots of buzz and noise - it really gets to you after a while.

I read with interest that at the peak of the Lotus 7 copy car bike engine craze that 80% of the cars made were bike powered (Hyabusa'a the bulk of them) but not so long after 80% of all the used cars with low mileage up for sale were those same cars.

Something to think about - if strictly track day car go for it, if a lot of road use think harder about it, especially if your in the over 500kg bracket.

Thanks for the info. I decided not to go the Hayabusa route once I saw that the differential setup would be nearly as expensive as the engine/transmission itself. I'm looking at making the R-C-R Superlite Roadster using a Mazda DISI motor--278 horsepower can't be wrong...

[cheapracer]

Firstly I will mention I actually drive a 2.3 Mazda 6 so you can't sell me on them, I'm already there.

I don't know why you would want to go for such an engine, 4 cyl vibration, heavy, intercooler to be placed somewhere, plumbing everywhere (intake and exhaust) and not the best type of powerband to have with a lightweight car etc.

Look at a Nissan V6 or similar.

[cordycord]

My friend is willing to give me his brand new DISI motor/trans/wiring harness for free. Does that sound like incentive? :)

I've got to disagree with you on vibration, weight and powerband. The DISI has a great torquey powerband, is smooth as all get-out and is relatively light. Plumbing? Yes, you've got a good point there.

I'm interested in the source of your knowledge /experience (?) on Hayabusa powered cars.
1st -Have you ever ridden in a Hayabusa powered car or are you quoting some unknown internet source?
Your statements are just incredibly ridiculous.
Let's review -
"Have to rev them all the time, change gears all the time, overtaking on a highway requires changing down 2 or 3 gears and lots of buzz and noise"

The Suzuki Hayabusa engine is a great solution for a lightweight car that is geared correctly i.e. 3.2 or similar. The reason for the low numerical gearing is that the bike transmission has an internal multiplier. A stock Suzuki Hayabusa motorcycle has a top speed of close to 200MPH. A stock Hayabusa powered BEC with 3.2 gearing has a top speed of less than 140MPH.

If you had ever ridden in one you would understand how wrong your statements are.

"at the peak of the Lotus 7 copy car bike engine craze that 80% of the cars made were bike powered (Hyabusa'a the bulk of them) but not so long after 80% of all the used cars with low mileage up for sale were those same cars."

The Hayabusa is very expensive in the UK and therefore is not used in many of the BECs. The much smaller and more common Honda Fireblade is used in the majority of the BECs. I and many others would be interested in your source for all of these used BECs with low mileage.

"especially if your in the over 500kg bracket"

The Suzuki Hayabusa engine and trans together weighs about 180 lbs. If the car is properly designed it will weigh considerably less than 500kg.

It's a Suzuki Hayabusa engine not Hyabusa.

He he!

Chet, i'm not interested. I took the time to post to offer my opinion based on my own personal experience, if you don't agree with it thats just fine by me but I hope it gets someone else a little broader thinking to obtain a better result :-) The only thing I will mention is that I clearly stated 500 kgs in my post and you would be suprised how many home builts fail to be under that as are their owners.

Thats the best incentive i could think of!! Congrats, :clap: (Can I be his friend too?).

You can disagree all you want about vibration, primary and secondry vibrations in 4 cyls are a nightmare for designers and your basing your statement on the thousands of hours granted to you by Mazda Engineers (hope you can match their prowess!). I notice the latest Ariel 3 has totally revamped engine mounts for example and boasting about it on their website. I wouldnt be suprised if they asked Honda Engineers to help them with it.

The torque of a turbo comes in pretty hard and not so progressively as a V6, not ideal in a lightweight car, I was just sighting options, trying to help, good luck with it :-)

Cheapracer, you state "I took the time to post to offer my opinion based on my own personal experience,..." well Webster defines experience as - "direct observation of or participation in events as a basis of knowledge"

Based on the fact that you failed to answer the question if you've ever even ridden in a Hayabusa powered car should we assume that you haven't? If that's the case then what "personal experience" of the subject do you actually have other than possibly reading some mythical statements on the internet from another person with "experience"?

I obviously do not agree with your posts but I always welcome opinions unless people try to mistakenly provide them as facts.

[cheapracer]

Chet, free world, assume away - did I kick your dog in a previous life or something? I really don't understand this.

Ok I'm terribly sorry about your dog, I can only live my current life the best I can and enjoy attempting to help and share with others. I don't get paid for this, I seek no reward and I certainly don't expect to be attacked for it either.

If you want my personal history, I am quite happy to share but the bottom line is that you wouldn't believe it, you would only scoff at it, say it wasn't true blah blah..... so whats the point?

Anyway for others, heres some pictures of me in 1 of my 2 car factorys with my latest electric city car I'm developing and I promise to post pictures and details soon of my latest Exo Car in development (the reason why I am hanging around in this forum now, not to have ego/flame wars) as well as my current 80% complete sports car.

I can't show you my bike powered race cars or give you details of them because thats an exclusivity part of my contract with my client, sorry.

[cheapracer]

Ok Chet, I'm really bewildered by your attacks so I'm guessing;

You ride a GSX1300R?

You sell or rebuild GSX1300R engines?

You have a kit car/locost etc. with a GSX1300R?

You make or sell kit cars.locost etc. and reccomend GSX1300R's?

What score did I get?

[cordycord]

cheapracer,

I saw your car--it looks like a copy of the new Tata, right? And you no doubt know that Renault had a "Le Car", right? That little R5 Turbo was a fierce little ride.

As for 4 cylinders being buzzy, let's think about this for a minute. This engine is going in an open wheel car that has only a minimum of wind protection and no creature comforts. Complaining about any type of NVH in this car is like complaining that it doesn't come with a shower attachment. :D

[cheapracer]

cheapracer,

1/ I saw your car--it looks like a copy of the new Tata, right? And you no doubt know that Renault had a "Le Car", right? That little R5 Turbo was a fierce little ride.

2/ As for 4 cylinders being buzzy, let's think about this for a minute. This engine is going in an open wheel car that has only a minimum of wind protection and no creature comforts. Complaining about any type of NVH in this car is like complaining that it doesn't come with a shower attachment. :D

1/ No, sorry. if it looks like the Tata its a coincidence. Various front and rear moulds were taken off an employee's car (cheap R&D!), some parts of the shape already existed, I cut and shut a roof off a theme park bus we sell and the doors were from another friend's car with custom window frames based on requirements from my primary customer for it (more height).

2/ I can't disagree with your general thinking but making something more liveable with is always worthwhile. And I'll mention again that Ariel seem quite proud of their new engine mount/less vibe setup.

Maybe its because I'm from Oz where we grow up driving big inline 6's and V8's that I notice the buzz/vibes/how many gear changes compared to some other countries and what they grow up with. My last sports racer had a Kwaka ZX1100 engine then later I went for a Subaru 2.2 EJ22 engine and lap times weren't much different but it was so much easier to drive with half the gearchanges and more torque. I hear that car now has a WRX motor with 450 hp and 480kgs. It only had a 84" WB and 58" tracks, good luck with that!

[cordycord]

Well you've clearly struck a nerve regarding me and 4 cylinder engines! I'm in the motorcycle industry (among other things) and the only engines that strike me as buzzy are the single cylinder type. I've had several Ducatis--people pay more for the vibe, you know?

Whereabouts is your operation? I make it to Guanzhou and Dongguan on occasion.

[cheapracer]

Sorry if I hit a nerve, I'm always up for discussion and my purpose isn't to pee people off! I'm for and support any 'special, kit car, race car etc.', love it all!

I had a couple of 70's Dukes, pre Japanesed, Italian electrics put me off for life, he he!

I'm in Chengdu and Deyang, Sichuan Province - make it here anytime, "wo mai ni beizi cha he kan kan meili nu ren, huang ying" :-) (I will buy your tea and we can look at beautiful girls, welcome).

Either public or PM me about the 'motor bike' industry, I work out of a major motorcycle company's factory here and they are my production partner for an upcoming vehicle.

Anyway, better get back to my Exo :-)

=========================
I know now they also make narrow and broad gear ratios. Those with a turbo added can cut you amount of shifting down quite a bit. Being sequential by shifter or push button, up or down gear changes are a snap.

Plus you can always get a quiet muffler.

Experience: Just driven a lot of bikes. Buzzy Engine's are 2 Stokes. ;-) I guess there is alway perspective and personal experience. Cheapracer, you car is coming alone nicely. I'm really glad there are so many small affordable FUN cars coming out. For the bang for the buck, they can't be beat.
