how to make a car rev longer?

[Vinnie]

chuck in a motorbike engine sum1 put a hayabusa engine in an escort and turbod it and it revved to about 15k from memory ran 13 sec quarters too...

besides, any engine can rev really high u jus have to be prepared to go thru a lot of engines

[koldfire]

i was dreaming then accidentally downshifted and rev till 11krpm on B16A for 1 second long...FREAKED! it's got titanium springs n retainers though... wonder if that would damage anything...

with the ability to rev up to 10k rpm, you AT LEAST need better/stronger springs and retainers, and also an ECU to remove your redline(fuel cut point) but my question is, why you want 10K rpm? even with bigger cams like these stage3, it wont make any more power at 9-10k rpm range.

here is an example for you. this is one of my friends allmotor B20Vtec, with his build, the motor has no problem to rev up to 10k rpm, but have a look at where his peak power at and how it drops afterwards. he had a run with255/182 at best, power delivery was very rough and it was a small spike at 7000rpm with that run, so the graph didnt as smooth as this one.


for others that interested in his motor here is a pic of it, and i also have his dyno clip

Nah, its been done, but mainly v-tec engines though
Alot of work is involved

you're not serious are you?

That dip in power at the end is because it's hit the rev limiter. Power production tapers off gradually until a point then it dies.
The graph below does not taper, it jsut dies!

The redline on that motor, according to that graph is 8.5k, not your imaginary 10k.
If you believe its a 10K motor based on that dyno plot, then you'll believe pigs fly!

If you're saying that the engine was run upto 10k and subsequently it was determined that there was no power up there, then I believe that, but I assume the engine builder and tuner have determined 8.5k is optimal due to the geometry and build of the engine.

btw: There are cams on the market that make power to 10k, it doesn't appear this engine was cammed that way, and it wouldn't make sence to build a b20 that way.

here is an example for you. this is one of my friends allmotor B20Vtec, with his build, the motor has no problem to rev up to 10k rpm, but have a look at where his peak power at and how it drops afterwards.

Fark that looks like an animal. YOUTUBE that shit for sure!

ProECU, they set the redline at/about 8.5k rpm, what i was saying is, with his build, his motor able to rev up to 10k rpm, but there was no point to rev that high bcz the way they build his motor.

you're in Sydney and this is a LEFT hand drive ??

[MaskedAP1]

yes, just moved to sydney, and used to live at vancouver canada.

[xtercii]

that's krazii power for an NA motor, what sort of time is this car running?
