hiya! :D :O

I am sorry for being such a noobie myself :eek: But I am still new to the car world and GT3 is my first actual Gran Turismo game and when I actually start liking cars. Yea...anyways.. :D
I am concern about putting the car on Nuetral and pressing the accelrator pedal to hear the sound from the engine which also leads out of the exhaust system. But I dont know if its healthy for my Camaro Z28 :eek:
Only one person at school told me its not healthy for the engine to Rev it. So...I would like to know you guyz/gurls knowledge if reving it is healthy for the car or not.

All I know is that to not let the RPM meter reach the Red Zone of the RPM meter and thats it :lol:
Thanxie :D
 
It should be ok. Don't rev it into the red. Don't keep it at high revs for a while. And don't do it when it's cold.

Why do I get the distinct feeling you aren't even old enough to have a driver's license?
 
the only problem I could see with doing that, is if you reved it to high (into the red), did it when the engine was not at a good operating temperature, or did it for too long, because obviously there is not much airflow to cool the engine when its not moving!:D
 
What could happen if you get high into the rpms when the engine is not at full operating temp.? Like, what if it's half to three fourths of the way there, but still not fully?

I've done it twice in the Cobra, and am scared I might have ****ed something up, but everythign seems/runs fine.

BTW- I'm not talking about pulling all the way to redline(6500) - more like 5000-5500. THis is also while in gear, moving. Not out of gear just sitting still.
 
Well, what you have to do is to rev it near the redline and then shift it to drive, that'll make the engine run better.

:)

Seriously, it won't do anything bad, it's just like revving a manuel while holding the clutch. Just don't hold the engine at high RPM, and don't go into the redline(technically, you can, but why would you want to, and you can screw things up if you hit the rev limiter/fuel cut-off.
Revving can actually help the engine, on a very cold day, holding the engine at 2000-3000RPM will get it to normal opperating temps quickly so that you can drive the car in a normal manner instead of babying it right after leaving or waiting for it to warm up.

Ofcourse, I use to just start and go, I've even had the 323 rev past the redline while under full acceleration while the engine is cold, and I know it went into the redline because since the trans was cold, it didn't shift to 2nd as fast, and I could hear the engine revving higher than normal(I don't have a tach, yet), normally it shifts to 2nd at 32mph but it shifted at 35-36mph, and I could feel the car leaving the powerband, lol. Ofcourse, no damage done, but I don't do that anymore.
 
Josh, don't worry about it. It's just better to be easy on things until you know the oil is warm and loose and made it everywhere it's supposed to be.

Does hitting the fuel cutoff hurt the engine? I have never done this intentionally, but I dont have a tach, so in spirited driving I will occasionally hit the fuel cutoff in 1st or 2nd gear. I know that high revs will wear out the engine quicker, but is hitting a fuel cutoff @ 5600 RPM much worse than running it at 5500 RPM?
 
I wouldn't worry about hitting the fuel cutoff, it's purpose is to prevent engine damage. Although I've never done it myself, I guess it could be bad if the fuel cutoff is above the engine's redline.

I've bounced off my rev-limiter quite a few times under hard acceleration with no problems. Some other people with '03 Cobras occasionally have problems with their gas pedal getting jammed into the carpet, and some have had theirs bounce off for up to 15 seconds(idiots reached down, and unjammed it while it was happenig rather than kill the ignition, then unjam it) with no damage reported.

It's definitely not something I like doing. It could probably create a lean condition, and **** something up if you just let it keep hitting it like that.

And have you ever watched any Supra videos? A ton have them doing burnouts just bouncing off the rev-limiter like it's nothing. They don't seem to mess anything up.

Still, though, with a turbo/blower it could only be worse for it.

I usually always wait until the needle is at its normal point, but on those 2-3 occasions I didn't have enough time(20 minute work break) so I let it warm up as much as possible before I got on it(for some co-workers). It's ridiculous how long it takes to get it to fully warm up. Those two times that it wasn't yet warmed up I had been cruising around for exactly 9 minutes at around 3,000 and it still was only half-way to its regular position.

it happens to me all the time in my skyline, when it comes on boost it comes on hard and induces alot of wheelspin and hit limiter straight away. the manufactuer is aware of this and places the limiter in the right place. the limiter feel to early on my car (it pulls damn hard al the way up to it), but im not going to change it

I guess it would be ok if the engine was built to take that kind of stress?
 
Sometimes it helps to rev the engine abit high just to check for any unusual rattles which will be easier to notice at high revs.

hiya! :O

I am old enough to drive :D I am 17 :lol: , but just got my license about 1 month ago :O

Also, thank everyone for telling about this for my thirst for noob car knowledge, keep it going and ill keep listening :D :D

hiya! :D

Well I do know something about cars :D But its a sad thing how I only pretty much learn it from playing Gran Turismo 3 :O The purpose of learning from it is to help me understand and "know" the car a bit. And I also conduct alot of research online about certain cars that are popular such as the Skylines, RUF, Vipers and it goes on and on :D
I am not a "technical" smarty yet like all you geniuses :O , I am only a "basic" VERY BASIC type gurly :O I am only familiar with basic stuff like the type of cars that have drives like, FF, RR 4WD etc. V8, V6, Inline-6 and it goes on :O
Anyways... yea I am a basic compared to all you smarties :O :D
 
Hitting the rev limiter won't do any real damage to the car. The whole point of the rev limiter and fuel cutoff that follows is to prevent the car from being damaged after all!

And honestly, if your car CAN actually go into the red zone a bit it's probably okay because most cars have their red line 15% earlier than they need to. That's why my engine's red line is at 5300 rpms, while the engine can handle about 6200 rpms. Often times when people install performance chips in their cars and tune them the rev limiter is raised to be closer to the engine's physical rev limit. So like if I had one I'd probably go to 6000 rpms.

Another thing to consider while I'm at it is that the 6200 rpms is about what my engine can handle before shortly throwing a rod or something. Sometimes an engine doesn't even have good enough gear to reach it's physical rev limit. For all I know maybe my motor can actually go to 8000 rpms, but maybe the injectors, cam, internals' balance, etc. aren't good enough to get it there. There are a lot of factors really.

So having a car in neutral and revving it up is fine, you can probably do it safely all you want. But as said previously, it WILL shorten the life of your engine, and you DEFINITELY wanna wait till it's at it's constant operating temp.

I remember one time I was racing my friend's Camaro in very cold weather and it was basically right after I turned the car on. I blew a coolant valve by the end of 3rd gear and I'm d*** lucky that's all. :O

EDIT: And for you guys with auto trannies, don't rev high in neutral and then put it in D -- it is NOT the same thing as a clutch drop and you can easily damage the transmission that way!

hiya again :D

So what do you mean by it WILL shorten the life of your Engine
"But as said previously, it WILL shorten the life of your engine, and you DEFINITELY wanna wait till it's at it's constant operating temp."

And also, about how you said about people with Automatics, Reving it in Nuetral and then putting it in D "Drive", do you mean as in more like Rev it and dont put it on D until the transmission rotation STOPS in the engine and then put it on D?
:D
 
only put it in drive when the engine comes back to idle

also i dont know why people have an obsession with reving engines in neutral, a couple mates of mine used to give there cars a few revs before they turned there engines off, because it sounded cool:rolleyes:
 
Ok I am going to tell you some stories. Everyone has given you some good info. I work at a autoparts store and we have a machine shop. I have seen things that should not have happened, so every thing I am going to tell you is so that you can learn more.
Reving the engine helps clean out the fuel lines and helps to get rid of carbon deposits. Reving it just to here it; bad. If the oil is NOT up to operating temp, it dose not flow properly and could starve your engine. No oil= seized engine. I have put a few rods through my race engine just by having a pick up problem. It only takes s few sec to do damage.
Shutting the fuel off at a high rpm CAN burn your pistons.If that happens, time to rebuild. Racers do shut off thier engines at high rpm when they are coming off the track.(oval racers) They get away with this because they all run a manual transmission. They push the clutch at the same time as they shut off the engine so that it stops right away. Holding your engine at high revs for too long can cause "valve float". If this happens, the pistons MIGHT hit your valves and cause some major damage.Bent valves,cracked heads, and so on.A V8 dose sound nice when reved, but don't make it a habit.

I have to disagree with that. To clean out carbon deposits in the engin effectively one should ideally do some freeway driving at a constant 100-120kph for 2-3 hours. Revving the engine for a few seconds will do hardly anything to clean out the deposits.

Secondly, from what I remember reading a while back, revving the engine in neutral IS bad. When an engine is revved high on the move i.e. in gear, the pistons and piston heads have the inertia of the engine/transmission to move against.

With the car stationary, the only force keeping the piston-head from flying into the cylinder head is the piston. It is extra stress on the components that, for the most part, is unnecessary.

:grumpy: Well what I read was something to that effect anyway.
 
There is a old trick, you mix soap and water, rev the engine to about 4500 and slowly add the mixture. It cleans out all carbon and you don't get a ticket for speeding. And yes it is better to have a load on the engine at high rpm's.
 
have you ever heard of water injection??, it works well
