I almost hate to even ask this, but I was at a car show earlier today and a few people really wanted me to rev it up before I parked. I did and noticed for the first time it will only rev to 4K rpm. I have an A8 by the way. Is there a way around this? Not a big deal but it would've been kinda fun to really let her bark. The damn car had a crowd around it and I was parked right next to a new Hellcat Challenger. Here kitty, kitty, kitty.....

Thanks guys!

Bad practice for any engine.....

Yeah, I know. I'm only talking about once in a great while. I'm not a kid. I was just curious if there was a way around it (besides custom tuning)?

Thanks

vipervetteguy

Didn't mean to treat you like a kid. Sorry.

No worries. This is why I didn't even want to ask. I was more curious than anything. Obviously this was the first time I even tried revving it.

Were you in neutral or park?

Obviously someone who hasn't gone on an assembly plant tour. You can hear everyone of the Z's at the assembly plant when they are started for the first time over the Stingrays. They "bark" and the assembly plant folks make sure they can. The once in a while throttle "blip" at a car show with the engine warm or at least semi warm and oil pressure up, IMHO, will do very little damage, if any, compared to a bone cold first start up. Would I do it every day, hell no, but like they say "if ya got it, flant it." And I hope to keep the "kid" in me alive and well as long as possible.

I have an A8 too. They say the exhaust opens (barks) at 3500 rpms. If what you say is true than GM programed a good thing.

Park

Try neutral next time???

CONMAX

Most SC engines won't rev much except under load. Since the SC won't produce boost w/o load, the engine chocks for air.

STill a bad idea. Neutral or park.

Revving a warmed up engine doesn't hurt a damn thing. Just don't bounce it off the limiter for extended periods.

JackTripper

Exactly. Just ensure the car is warmed up. Whenever I go through a tunnel, I press the clutch, give it a couple revs and smile.

Where did you hear that? Most automatic vehicles have a low rev limiter while not in gear to protect the torque converter from a red-line slip shift. Nothing to do with the supercharger.

Rev it high enough and it is.
Tell an old neighbor who love to rev his engine. It coughed and stalled and next thing the wreaker was there to get it. The car never returned.

Revving an engine is needless and serves no purpose.

I always heard it was bad to rev a engine. It has no load.
I hear someone revving the engine I think idiot right away.

But I guess different strokes for different .......

racerns

Pretty sure these engines have a bypass valve that are open when the engine is not under load.

Well at least this thread will let me know who not to buy a used car from!!

Dear Lord. You guys are funny how you can take something and run with it. It was an honest question. And thanks for calling me an idiot for revving "my" engine once or twice a YEAR! Geesh. Don't worry about buying my car. It won't be for sale for a very long time!! Not all of us are kids with daddy's car, guys. I've worked my whole life for this car. I wasn't asking for anyone's approval. Just wanted to know "why" the car would only rev to 4K? Nothing more.

Rev it up, won't hurt the engine As long as the oil is somewhat warm. No load, no nothing, Engine doesn't care. Don't sit there & bounce it off the rev limiter like some silly guys do... A dyno pull to redline puts a lot more stress on the engine.

I believe most autos will not let the engine rev past a certain number to protect the trans. I'm not sure if it's the torque converter or what, but I believe this is pretty common.
