Replying to: robertsmx (Nov 29, 2007 4:18 pm) So, it ain't all about rpm, but design and engineering, and considerations to durability. Besides, the last thing I would worry about in a Honda (Accord) will be its engine. |

Replying to: robertsmx (Nov 29, 2007 11:36 am) Honda B18C used in Integra GS-R had a unique honey-comb cylinder lining. It was engineered to rev higher than a typical engine is. You can't apply a generic statement while ignoring facts like these. I don't understand "honey-comb lining." I am thinking it is something like the Crinkle Chrome applied to some cross county motorcycle racing engines back in the 70's. It was a super smooth, supper hard, chrome-molly alloy plating with a spider web of microscopic fractures which held on to the oil better reducing friction of rings to cylinder walls. You mention "apply generic statement while ignoring facts like these" but I don't see any facts in your statement. Are you saying that an engine with a honey-comb cylinder doesn't have any friction anywhere in the engine? I know from your other posts you are way to knowledgeable to state an assumption like that and I won't assume that is what you were saying. I just am missing the facts you elude to, I guess. Maybe you could describe the facts to me more clearly? Other post on this thread have made statements along the lines that RPM has no effect on Honda engines. Honda must have figured out how to completely eliminate metal on metal contact in an engine, which would be the greatest discovery of the 20th century, and maybe the 21st . With this technology we can solve the oil crisis because we wont need it for lubrication of anything in the future.

I think the design of the piston itself, the design of the cylinder wall, the way the rings seat and the material they are made of, and the coatings they use on the cylinders, pistons, and rings helps too. Modern con-rod bearings seem to show almost no wear after hundreds of thousands of miles if the oil was maintained. The Contour held 5.7 qts of oil while the Accord held 3.8 qts. Because the Contour was tracked, it got synthetic, but I didn't have an issue with either one. I wanted to make sure there was something protecting the bearings when the vehicle was oil-starved during hard cornering, so synthetic seemed like the way to go. 180k later it was fine, and that was high load, high RPM driving. I personally am not worried about revs in a motor, as long as its within its factory limits (if you start reving a 7500 RPM redline motor to 10k you might have an issue). In my opinion, manufacturing tolerances are tight enough between all manufacturers. |

Replying to: targettuning (Nov 30, 2007 7:21 am) I agree with your post. You stated the point very well. |

| With regard to climate control, the auto. climate control on my 08 Accord EX-L works great and I have no complaints. Ms. Bug4 loves to put her temperature 10-12 degrees hotter than mine. The system handles the temperature gradient very well and, because the interior is so large or for whatever other reason, the system seems to be able to maintain significantly different temperatures from one side to the other. Other than its initial attempts to get the car up to temperature, I'm impressed with how quietly it operates! Now, having said that, I haven't had anyone in the back seat for an extended trip. So, who knows, maybe the climate in the back seat is unbearable?? I am disappointed the new Accords don't have any duct work to the back seats! | |
