Does revving the car damage anything ---

No but it really serves no purpose . Why are you asking? ---

It serves a purpose for me I’m currently changing my exhaust I’m trying to find which brand sounds the best I’m wondering bc to here what it sounds like I have to rev it up I just wanted to be sure before I started doing it just to ruin things ---

Loud exhaust on a 2008 Impala , seems like a waste of money . ---

I re did the motor It’s a 3.5 I put a turbo cold air intake with a performance chip upgraded cam and a bunch of other stuff so i get what ur saying but I already have a bunch of money into it ---

I put FM 40s on my car, sounds good outside, but resonates inside while driving. ---

Rev’ing the engine puts forces on the internal parts that otherwise they wouldn’t be subjected to at normal idle rpm. So it does damage or at least increase the wear of the engine a little. Not something to beoverly worried about as long as it is only a brief rev and stays well below the engine’s maximum rpm spec. ---

> [@Tyler13](#): > > I re did the motor It’s a 3.5 I put a turbo cold air intake with a performance chip upgraded cam and a bunch of other stuff I find it interesting that you were able to chip a car that has no provisions for a chip. This engine is tuned via hand held tuner or a laptop with the appropriate OBD-II connector. I’m not sure if going to a different cam was really needed as this engine has VVT. ---

The performance chip is connected to the mass flow air sensor if I’m not mistaken and I definitely know that the performance chip is on my vehicle ---

It seems like it would be possible to put add’l circuitry between a sensor and the ECM to cause the ECM to run the engine differently. Maybe that’s what happened. As I recall there’s been some posts here about installing custom circuitry between the O2 sensors and the computer on certain cars to make the CEL turn off and stop complaining about the cat. ---

There aren’t any piggyback chips for gas powered cars that new, at least none that I’m aware of. I know Ford you could get them for Ford’s EEC-IV ECU, but those haven’t been common since the mid 90’s. GM’s “chip” tuning consisted of custom burned EPROM’s I want to say went the way of the dodo when the LT-1 went away. Anyway, you’re not going to be doing much with a “chip” that plugs into a MAF sensor at least not enough to make the necessary tuning adjustments to accommodate a turbocharger. ---

The engine is more healthy when it does what it is suppose to. DRIVE! especially on a highway… ---

Depends upon what you mean by rev. If you mean flat on the floor and hold it there then anything is possible. The rev limiter shoujld keep it under control BUT if the engine mechanical condition is pretty shaky then it’s possible to blow one at the limiter. If by performance chip you mean one of those things that go onto the MAF sensor or ECT then that is a scam that will do nothing. If by turbo intake you mean one of those intake air or electrically driven impellers then that also is a scam. The latter was recently dyno tested and a 5.0 Mustang lost 30+ horsepower with it in place.Best of luck anyway. ---

“…but I already have a bunch of money into it.” This would be a good time to stop putting money into it. Classic case of a ‘sunk cost’ -google it. The benefits you think you will get will cost more money and performance may suffer and I bet you will be disappointed with the results. ---

> [@VOLVO\_V70](#): > > turbo cold air intake No, you put a cold air intake on it. If there is any “turbo” at all in the device it is an electric fan, and as @ok4450 posted, does nothing. In fact it likely hurts performance. [Next page](https://community.cartalk.com/t/2008-chevrolet-impala-revving-cause-damage/150461.md?page=2)
