Cruising regularly at 4000 rpm

Honda who is known for high RPMs wastes so much time combating the mythical cylinder wear. They use oil jets, carbon reenforced sleeves and molybdenum coating on the skirts. But they’re still notorious for blowby. My old Integra drank one qt per day after about 200k miles. Obviously it had nothing to do with high RPMs. I mean there is no wear involved with metal rings sliding along another metal surface. Doubling the number of passes will literally not add any additional wear.

The FA20 has none of the precautions Honda takes so we are in better hands. Go ahead, sling your hearts out.

4000 is not high for these engines.

I never said it was. You can pretend you don’t understand what I’m saying but I trust you’re smarter than that.

I got my answer people, stop talking lol

NOT YET!



I'm still waiting for a response from @Tcoat for the question I asked in post #215 .......

Either he is ignoring the question OR he has opted not to follow me down that pig path .......

@ermax ...... maybe we will get them after all .........

Not going to happen. He has his attorney over there saying, “don’t answer that question”. Hahaha

I figure he @Tcoat is conspiring with ol @PetrolioBenzina , to figure out an answer for my question in post #163. The only thing he (PetrolioBenzina) came back with was with what gears were involved ...... which is totally irrelevant to the question .......

Ok I will play. First you have to tell me what the difference in operating temperature is between 2,000 and 4,000 RPMs. If we are going to say that heat causes "extra" wear then we need to know the dramatic different between the two engine speeds.

I already answered 163. Do you remember what you had for dinner last night?

[ermax]

I have a close relationship with the developer of the physics engine used in the simulator which is used by the entire F1 field. I will connect you with him so you can let him know his engine wear simulation is completely flawed for using RPM as a variable.

You are seriously overthinking this. No one is debating or looking for a way to quantify the extra wear. Just admit that there is more wear at higher RPMs than lower RPMs.

Oh, OK ......my bad ......you did address the question in the post #163.

The question was:

So, allow me to ask a question.

You have two identical 86s, you are going to drive both for 100,000 miles at 60 MPH.

On one car, the revs will be kept at 2,000 rpms.

On the other car, the revs will be kept at 4,000 rpms.

At the end of the experiment, your tear the engines down and inspect for wear.

Which one will show the most wear ...... or will they be the same .....??"

Your response was:

"The difference if any at all the would be so minor that you would not be able to see it.

The numbers look like it should be different but the engine does not care if it is doing 2,000 rpms or 4,000."

Maybe I should have made it multiple choice, because I don't see an answer .....

As far as asking me what I had for dinner last night ...... I answered that by saying that I didn't remember ....... now, it's a day later and I still don't remember. Ask me two years from now and I probably will remember ......

Now, what were we talking about .........

My question in post #215 was:

"Is it friction, or is it heat caused by friction, that wears out engines .... ??"

Your response is shown up above.

That response didn't answer the question......

Your move .......

PS - the toddler just came to me pulling on the back of her diaper ......that means a poopy one ...... and ma ma is busy with helping the other two with their homework ....... be right back ......

And there is the question in a nutshell ......

I think what I'm getting from this is that yes, higher rpms do create more wear, but it's negligible compared to the other sources of engine wear such as cold starts, assuming the higher rpm driving is done when the engine/oil is warmed up properly.

[humfrz]

Where did ol @PetrolioBenzina run off to ......??

Maybe he discovered the error of his ways and is standing down ...... ??
