Does that mean I might have a tune from previous owner? Where does the Rev limiter start on he m6?

6600

OP... If I read your story correctly.... you moved to the fast lane at the same time as someone in front of you and had to downshift to slow down? Why would you downshift from 5th to 2nd at 80MPH when trying to slow down? Why not just shift to neutral and brake?

Hmm. I better be careful because that does not happen at all with my car... so I guess stonebriar sold me a non stock tune or something not working? How can I confirm this was tuned out?

Take it to any Chevy dealer. They can tell you. All they need to do is hook up to the OBDII port.

Checked logs.. highest was 7200 not 7400..

Redline refers to the maximum engine speed at which an internal combustion engine or traction motor and its components are designed to operate without causing damage to the components themselves or other parts of the engine.[1] The redline of an engine depends on various factors such as stroke, mass of the components, displacement, composition of components, and balance of components.

Then I will say you both are wrong. The redline on your Camaro is not at all where the engine will come apart. In fact, its not even close. lets talk a more high end version of the old redline, the shift light. Whether is is a single bulb version as is common in drag racing or the progressive system found in may road course cars like Formula One (there are even systems that can be used in our Camaros that are progressive), the goal is to get the driver to shift his car at the optimal RPM, not to warn him that engine is at its limit. I do agree that there are many factors that control both the engines power producing range as well as its max RPM before the components come apart. Let me ask you this. The redline on the gen 5 SS Camaro's is right about 6200. I promise you you can spin this engine past that point by multiple hundred RPM and not do it any damage,. though your power will drop off. I think we are stuck on the definition of redline, and as I started, I would have to disagree with yours and Mr. Wiki's.

PS: Also consider the other poster's comments. If the electronic rev limiter does come in at 6600, why would they put redline at 6200? Would not the engine come apart in those 400 RPM? Of course we know it would not.

Keep in mind, redline is not the spot where the engine gets in trouble, its the spot where it engine power begins to fall off. Different gears may get you to redline faster, but really will not change the redline.

Technically both of you are right. While it does describe a point in which the engine would be damaged, the actual 'red' 'line' on a gauge for any given engine is set where its power falls off. Changing the cam could make power beyond the previous redline but it doesn't mean its doomed to failure.

Torque logs.. that is weird thiugh.. I found another thread where the Rev limiter kicks in at 6900.. not too far from my 7200.. maybe that's it.

Either that or torque takes a dump sometimes..

You know how it's common practice to hole shot everyone that cuts you off. I just wish the OP would admit this is a product of his road rage. I don't understand why you'd create a thread like this and then not be honest about it. No one was asking for the thread. Either tell the story right or don't say a word!
