Hayabusa 1300cc - best mass produced engine ever ?
Discussion
I was pondering the Suzuki Hayabusa engine last night and got to thinking it must be the best mass produced engine ever !
1299cc, 104 lb ft torque, 180bhp, will go for 50,000-80,000 miles (not heard of any higher ??) with only a valve shim adjustment and general servicing, still give 50mpg in a kit car and can be tweaked (easily) to about 220bhp with the standard capacity.
It weighs just 90Kg including gearbox, clutch, injection kit and the ECU.
With a turbo charger, new rods and pistons (std crank and head) will produce over 500bhp !
They can be purchased for £2000 and a full turbo conversion is no more than £4500 for 400bhp.
What other engine can compete with this ?

I'm really tempted to buy a Hayabusa bike but I'm sure I'd die within hours of getting it.
Just watched a video of a GSXR1000 going flat out at about 175mph (the lcd speedo was reading 28x km/h) and a turbo Hayabusa flying past it at what must have been close on 190 mph, pulling a wheelie ! Absolutely mental bike.
Just thinking of which kit to build next but a major part for me of the fun is with the engine. Ford/Vx engine may be cheap but they're expensive to tune and don't sound very good. Had been tempted by the Audi 2.7 V6 as used in the A4, A6 and S4 but again the cost of doing anything serious to them is prohibitive. I can see why people use big American V8's.

I'm not a bike rider and I've never had the chance to drive a 'busa-powered kitcar but aren't they a little tricky to drive? I mean, it is a brilliant engine and all but isn't it a little short of torque for car applications and isn't the powerband a bit narrow?
Now, imagine if they had built an I-6 engine from the same design. 2.0 liters of displacement, same ability to rev but with less vibration, a wider powerband and 50% more power to spread around that powerband...
Anyway want to cast me a six cylinder Hayabusa block?
Or what about mating two Hayabusas to a common crankshaft and creating a 2.6 liter V-8?
I'm more of a straigh-six guy myself but there's lots of folks out there who love a V-8...

Err 50mpg not likely. My R1 1000cc only gives 30mpg, and less than than if you thrash it. Thats only about 170kg.
Stick a 500kg mass around the 1200cc and you won't be talking anywhere near 50mpg. You can't beat the laws of physics.
You might be right...
still, doesn't the Lotus Elise get nearly 50mpg and it weighs around 800kg and has a 1.8 liter engine?

Yeeeeees, but the Elise engine isn't tuned to 140bhp/litre is it. Mores the pity.
You're comparing apples and oranges my old fruit.
You could I'm sure get about 50 mpg at 50 mph, on a light throttle . . . can't imagine doing it myself.
People keep mentioning lack of torque but even without a turbo, it's still got over 100lb ft at the crank, it's not a lack of torque you seem to thinik of when driving it, it's the lack of grip from most tyres. If it was a 600cc then yep, with only about 50 lb ft I gues you might miss it !
