I always wonder....how come a normal 4 pot engine from a car....... will not sound as nice as a 4 pot engine on a big cc bike ? I mean even with an after market exhaust on the car.....it still loses out in terms of sounding as nice as a bike..... even if both shared the same engine cc [drivingcar]

Because bike engine[4 stroke] can go as high as 15,000rpm while car engine only max 6000-7000rpm..so they sound diffrence.

why is car max 6000-7000rpm but Because bike engine[4 stroke] can go as high as 15,000rpm

 

why car not make Because bike engine[4 stroke] can go as high as 15,000rpm to same as bike?

Engine capacity. A Honda Goldwing has a low rpm range as a car. A typical 400 cc will have double the engine speed of a car (with a engine cap of typical 1,600 cc car). Rough rule of thumb for bike engine rpm at a given speed is double that of a car.

This is a no brainer question.

 

The answer is simple. For the same engine they are subjected to different amounts of load, be it weight, electrical load & mechanical load. Everything on a car is much heavier, requires more wattage and more power needed to distribute to other devices like air con, power steering, bigger cooling system, bigger gearbox & front/rear/4wd axle.

 

The motorbike is the minimalist. Everything on it is basic and less complex dan a car so the loads subjected to the engine is also minimal. Just imagine using a vacuum cleaner, picking up a piece of tissue paper vs picking up a rug or carpet and you will notice the difference in sound the motor produced which tells you it's under stress and overloading when picking up the rug.

 

To answer someone here why can't car engines go up to 15k rpm or more is simply becos you dun have the bank acount big enough to maintain your car. F1 engines can reach 19k rpm but they have F1 kind of budget to maintain their cars which are also much lighter dan ours. Go figure.

 

Our cars can only maintain that 6~7k rpm is also to meet CO2 emissions and FC. More loads on our cars also mean higher CO2 emitted and higher FC. Ha! 15k rpm on car engines.... some ppl already kpkb on the money they have to fork out during servicing and the fuel bill they have to pay every month.

As a Honda and VTEC fan, i hope the HSV will go into production.

 

That is 1 car with a V engine that sounds like a F1 car. Then TS will get his dream.
