u know when u rev the engine and the rpm shoots up? this is the first car where the rev falls extra slow. i was told this is due to some emission bs.

how do we fix it?

If you want the rev to climb up faster:

More power
Shorter gears and/or shorter final gear
Lighter flywheel


If you want the rev to fall faster:

Lighter flywheel

Lighter flywheel should fix that.

lighter flywheel + lightweight crank pulley

its not limited by flywheel, the electronic-controlled just keeps the throttle open longer for more complete combustion (and less CO emission). So far not sure if anyone has found a fix for it. It bothered me at first but is relatively minor so I just got used to it

my friends 350z is like that....i hate driving it lol

now that someone mentioned it...it does fall kinda slow. doesn't really bother me though, but a lightweight flywheel helps a lot in making it climb faster.

Try the sprint booster, i had it on my s4 and it worked marvelously

Took me a while to get use to that, my clutch foot felt a little stupid at first!

yea, its no big deal. i was just wondering if there was a quick fix for it. i dont even rev my engine these days. i used to like a **** back in my hs years with the celica...

that's the reason for the clunky and notchy shifting.

I never thought about it much, but that explains why it never gives grief when downshifting to slower gears as it hold rpm a bit.

Anyone w/ any feedback regarding the sprint booster on an evo x.

yep, i've been saying on here for a while that if you let the RPM's fall a bit more before you shift that the shifts will be MUCH smoother.
