Revs At Startup

[szymonsta]

guy i work with has an immaculate super-low kay 350Z HR and his also revs very high up to ~2k-ish on cold start up. i think its normal.

Yeah I get this as well, it's annoying when you're in a hurry and when changing gears on the auto (especially to reverse) at high rpms makes the car jerk...

^^ yeah hate that too. mine clunks (and even get a click from the back end)

Yup, I get the clicks from the back, but not so much clunks unless I change gears as soon as I start the car.

the high startup revs have been cured with the full inlet cleanup as per the direct injection thread

It's not just annoying, it's damaging to your transmission. If it's a cold start, let the engine warm up a little so that the revs drop to around 1000rpm or less. I never engage any gears unless it's completely warmed up - so, well below 1000rpm.

Yeah my engine stays down on cold for about 3-5 mins when it's been sitting outside all night i have a manual so i always drive like a grandma until my engines warm shifting before i need to and minimal acceleration.

It's not as big a deal for a manual since you can ease out the clutch (at the expense of possibly burning it out if the revs are too high). Still, it's much cheaper to replace a clutch than it is to rebuild an auto. It's the autos where we need to worry. Engaging an auto at that rev range is pretty much neutral-bashing it which is never a good thing.

Yeah good point, i just hate the idea of flogging the car when it's cold. Flogging it at all for that matter..

It certainly isn't ideal, but I don't think it is all that brutal to the auto, after all, V35 autos aren't failing prematurely.

The engine is reving but it drops fairly quick when you engage drive. So it isn't like holding half throttle and dropping it into drive and chirping the tyres.

I would wait if you have time, but not be too worried about it if you don't. It is probably worse for the engine and transmission mounts.

Yeah I always warm up my car so that at least the temperature is 3 bars above bottom cold and below 700 rpm. Still get a slight click sound and as suspect it's probably the axis click as its a common problem with our cars as mentioned on g35driver.

Yep i get the clicking from the back on acceleration. Also get a little bit of a clunk as i brake, but i do need my rotors machined pretty bad.

i warm mine up for about 5 seconds. dont care.

On a cold start 1st thing in the morning mine will fire up to 2000 rpm and then drop straight down to 1500 rpm, in gear it will be idling around 1000rpm, the click you guys are taking about is a common thing with V35s just do a search on it
