370z revs
 

Hey guys,

Just wondering... Ive been watching lots of car vids lately and noticed that some vehicles when revd up rev up then down really quickly. When reving the Z i find that it revs down really slow. What causes the engine to rev so quickly on the downward cycle?

D

do you mean when you are reving it in neutral it takes a long time to rev down?

It can be anything from the car's engine management to lightweight flywheels.

Yeah, thats exactly what i mean.

Lightweight flywheel will give you faster revs

i need my car to rev down super quick so i can rev it up again super quick:P this is bs man :)

not sure where this is going?????? :ugh2:

Well I do agree that while upshifting, the revs drop down a little slow when trying to get quick shifts, but not enough for me to buy a lightweight flywheel.

Lightweight flywheel will make most of the difference, engine management makes SOME difference too...

Everything you want to know.
Rotating Mass, Available Horsepower, and Acceleration
Thanks google!

If that's all you want, then, yes, a lighter flywheel will help. If you want to get obsessive about it, get light-weight crank, rods, and pistons.

Part of the problem, especially on increasing revs, is the 370 engine control system. It limits how quickly the engine will accelerate for better emissions, MPG, and knock control.

if you like chirping your tires into second gear leave the stock fly wheel on :D

Also rev down faster as well. Less rotating mass, but launching and driving are affected you will have to give the car more gas to get the revs up with a lighter flywheel. I don't know how our electronic gas pedal will handle that modification. I know with a standard link to the throttle body I had to do extra work to keep the car from dying going over bumps and launching with my light flywheel.

...and into 3rd with the 7AT! I like to pretend that my heavy stock flywheel is some sort of KERS system that adds to the kick in the pants when up shifting. :driving:
