General Punto With Hayabusa Power ....

The Hayabusa weight is 250kg, if your shell is 640kg without the engine, I don't think it's going to give the police much trouble. Consider adding 100kg for your engine, 40kg for your fuel, much less aerodynamic than a bike. I'm wondering how your gearbox and sprockets are going to tolerate those kind of stresses.

Interesting though.
 
He's junking the bike but even 1000Kg and 180bhp (with the standard engine) will be PDQ but he says he's going to turbo it.

The bike gearbox output shaft is the weak point. It will almost certainly need a special shaft with outboard bearing to better support the engine sprocket. Bikes cant use all the power from standstill, so the standard gearbox copes ok.

Atom (I believe it is) offer a Hayabusa based V8. Special crank and block with 'Busa internals barrels and heads. I'd hate to think about the fuel consumption.

I would like to see a blown 2 stroke radial in a car (or bike). One row of 4 has 4 firing strokes pre rev. Two rows has 8 bangs per rev. They dont use the crankcase for air & fuel so there is none of the popping and stuttering of "normal" strokers. And there is no vibration. Mechanically its fully balanced and its firing two or four times more often than a normal 4 pot 4 stroke so virtually no torque pulses either.
 
i cant find it now but a little while back there was a youtube video posted of a cinq that was powered by a yamaha r1 i think it was and all it done when he put his foot down was spin its back wheels and skid all over the place so i was just wondering how puntosales was gonna overcome this problem
 
If you floor any powerful car (or bike) it will simply spin up, but slightly less so if its rear drive. Sticky tyres and a light foot are the only way.

Bike engine are less bad because they have no low down power. The R1 probably wont pull at all below 5000 rpm then at 10,000 all hell breaks loose. Redline is around 14.

As WhiteSei says... you have to drive it differently.

4 cylinder Bike engines dont need much torque, no weight in a bike really so get the motor up the rev range.

Exceptions are the V twins which for a bike engine, have plenty torque.
 
Keep the revs between "fluffy rattly about to die" and the "OMG this IS quick" and its all quite docile. They are not like the old race 2 strokes that packed everything between 8000 & 9000 revs. Not as much fun either ;)

There was a 1950's style kit car that used a sports bike engine with a special 2 speed transaxle. High ratio was handy to keep it docile. Low gear was for full on power & let it rev.

to get the power down ... is all in the suspension settings ... harder at the rear ... tyre presures set right ... and well learn to adjust the way ya drive ...

get a rear wheel drive car .. M3 ... or cosworth .... all will spin the wheels ... sticky tyres and a different driving style .... but front wheel drive will spin up and give you an all over the road drive ... so slow and learn what and when ...........

FRONT BUMPER ... NOW WITH FRONT BRAKE DUCTS ...
