hmm real? or fake? hmmm i certainly hope it is real here ya go

 

Timing is off but I like the sound

 

thats fake. to make that much power up that high the ports would have to be custom and perfect along with some serious custom work with tripple valve springs. sounds just like an f1 dub over

 

Dub for sure. You can hear the first car but not the second car. And 18k on any street car motor is stupid.

 

i believe you need neumatic (sp?) pistons for that....not real

 

pneumatic... why would you need air powered pistons?

Oh and by the way, that's absolutely fake. There's no way an engine set up for road use would be able to turn that fast, there aren't materials strong enough to hold back a piston with the strokeof a road engine that's turning that fast.

 

fake..sounded like a jet though

 

^^thought that might be how you spell it

they do it on formula one cars. It has to do with the fact that the valve that opens and closes to let in fuel and air has a spring that pushes it into contact with the cam. At that high RPM's, the spring cannot push it fast enough to keep the valve in contact with the cam. Let me know if you have any other questions, cuz im not sure if i explained that clearly enough.

 

that phenomina ia called Valve float it is a bad thing but a self correcting problem both valves stay open thus not allowing proper combustion then the rpms drop thus correcting the problem think revlimiter that can never be adjusted(with stock parts) now a rotary and 2 stroke are not limited by this phenomina and are only limited by the streingh of the moving components in the engine

Lol where did that come from
