Since I got my 08 z06, everyone and their mother is always asking me
to hear the engine exhaust with the fuse pulled.

I got married this month and had a lot of parties so I been revving my
z06 pretty frequently.

My question is..is it harmful to just turn my z06 on and rev the engine once to like 6500rpm's in neutral and turn it off so people can hear it?

I know this is a pretty tough car and it built to handle things hard but so far this month I have revved my engine to like 6500 rpm's just to let people hear it like 4 or 5 times.

I just want to make sure I'm not F****** up anything.

Thanks

to me, as long as your temps are up it can't hurt anything

As long as the motor has had time to warm up.. then it should be good.
Cold revs = NO NO

well how long does it take your engine to warm up? I have been doing cold rev's. I hope I haven't been messing up anything. S***

Nothing over 2500 till it gets up to temp. Oil is not warm and you're wearing out your motor if you do that.

yanniz

don't do that, not good...

patton

maybe look at temp gauge..just a thought

Thanks Captain Obvious. What would be a good temperature number to aim for and how can I achieve that temp? Should I leave the car on for 5 minutes? maybe go take it for a spin? then it will be ready? I just want to know what precautions I should take so I don't mess up anything in my engine.

Thanks.

(I didn't know that cold rev's were harmful to your engine so I came here looking for knowledge from the best).

Your oil temp should be at least 140 before you rev it hard.

Thank you

vetteman24

this goes for driving it hard too. I never get over 2500 until my oil temp is up.

patton

ive tried to answer you on some other issues but you are a smart guy and i,m sure you can find operating temp ...or maybe not

Change your oil and follow the 2500 rpm rule. You'll feel better.

I wouldn't make it a habit to free rev the car at idle, regardless of oil/coolant temp. I see these idiots at these saturday night car meets that free rev like near the limiter (some bouncing off), and I'm just cringing maybe rev it to 4000 or something, but save the 5K+ for actual in gear situations

Never a good idea to rev it to those speeds in neutral...also a very immature thing to do just to impress your friends.

curvesman

How do you impress your friends? Hole shots!

Free revving the engine to 6500 RPM is just plain crazy, up to temps or not.. It should be quite sufficient to go to 3500 or so to satisfy the curiosity of the locals I would think.. I cringe at the very thought of my engine spinning over that fast under no load just so somebody can listen to it.. They might get a chance to hear something else.. Jeez.. tell them if they are around when you leave they can give it a listen..

is there any science behind these statements or is it just a case of "thats the way its always been done" or "an old tech back in 60s told me not to do that."

A car is like anything else....how would your own body feel if someone yanked you out of bed and immediately had you doing 400 meter sprints?!?!
