reving engine before shut down

[maxmonster]

do any of you guys do that? i know my boss/cousin does that for his beemer. i asked him why and he says its good for the car. he never gave me a straight answer but i was wondering if it is good for the car or not.

[Adv4nc3r_Mk5]

Its sure good for his Ego at least :happyanim:

[ekk20]

kinda like when civic's are backing into a parking spot revving the engine to 6000rpm so the vtec can help them get into it?


the only thing you would want to do is let the car idle for 30 seconds to a minute if you have been driving it hard. it allows the turbo to cool down a bit before shutting it off. there's a recirculation pump that helps with that AFTER you shut it off as well, but it's better safe than sorry, plus it's in the manual.

your lack of honda knowledge is showing http://www.mysmiley.net/imgs/smile/tongue/tongue0005.gif

vtec won't engage at low speed, you have to be doing at least 10-15mph

It's actually potentially bad for engine as the excess fuel washes the oil off the rings and drips into the crank. That results in dry start ups and diluted-less effective oil. While a much worse issue with engines with carburetors, it can still be an issue in FI engines.

lol @ your boss. he's the one that needs to be fired.

[maxmonster]

heard that

[bonton]

It would only be good if your car had a carburetor. The rev would prime it for the next start....my dad would do that in his old blazer, I remember asking him why.

[fraken5]

funny i did the rev thing in my '88 monte carlo just for fun... ahh straight pipes

To rev a turbo engine before turning off the engine is definitely the wrong thing to to, as the turbo is to cool down before turning it off. Actually, I cannot see any benefit in revving ANY modern motor before turning it off.

The only time I've heard of this is on RX-8's...if you haven't driven the car long enough to get it to operating temperature, there is a chance that the motor will flood. (I did it once moving it in the driveway when the engine was completely cold, and even though I revved it, the engine flooded, the dealer had to tow it, and the tech said he took about 8 ounces of gas out of the motor and had to replace all the plugs because they were fouled. Luckily they cover it under warranty.)

On the RX-8, you have to rev it to 3k then cut the motor, and supposedly it helps, the dealer even recommends it. It helps burn off any remaining fuel left in the housings, but again this is a rotary engine, I don't see the point on a piston engine.

edit: sorry, just saw he was family...so, I'll revise to "your boss/cousin is giving you bad advice, avoid doing that yourself."

kunta kinte!!!

sp?

[MoB$TER]

Tell him what a great idea it is, and how it helped your car alot if your lokking for a promotion :biggrin:

[WakeHead]

Boy BMW drivers are sooo smart. :clap:

[fierostetz]

tell him he did a great job of cleaning all that pesky oil off the internals before shutting it down ;)

[VMRSport]

I've never done anything like that before. I don't even think that revving the engine up to 3-4k will do anything to help clean the engine out.

I always make sure to get my car go through the complete rpm range once or twice a week though. That will definitely help clean and clear things out of the engine a bit. Won't do wonders or work any sort of magic, but it does help burn off excess bits of oil, etc.

I always love it during track days.

The experts riders cruise their bike into the pits and shut them off.

The novices roll in, revving away the whole time. Stop their bikes, rev a few more times, listening intently for something, and finaly shut off their bikes.

Meanwhile all the experts are looking at them like "WTF? are you doing?"

Used to be you had to rev car/bikes with carburetors, espeically ones that are set up for high performance and don't really like to idle because of the cams or the jetting. Then revving was "clearing the throat" of the engine so to speak to avoid bogging/over-rich conditions when initially taking off from a stop or low speed.
