if you develop carbon deposits if you don't burn them out every once in a while, then why don't more auto-trans have this problem? i don't think redlining is as common in automatics.

Rep Power: 787 oh yes it is, for me anyways Just change your fluid every 15k and get a cooler. I paid $50 for mine and installed myself. Very simple, cause remember heat kills 95% of transmissions that fail.
And fyi, I had alot of carbon buildup in my auto after 20k miles, especially on the pistons. I drove normally mostly, not really going above 4k very often. I open it up more now.

Rep Power: 294 This is much more common in old cars (i.e. carburated cars) and high displacment engines. Not that it doesn't happen in Honda's, but Honda's just run way leaner than most, so this sin't really a problem.

Rep Power: 249 remember when they used to have leaded fuel? ...I don't... but that's probably the era this sort of " redline eliminates carbon buildup" advice comes from I'll bet.

But yes, older car tend to make more carbon, but todays car make carbon too, just not as much, hence it is not needed to "burn the carbon" out as often.

Rep Power: 0 s2000man01 - Please understand that I'm not saying this to be confrontational but to keep people from damaging their engines and coming back to you. I think it's irresponsible to suggest to everyone here that redlining on a regular basis is good for the engine. For a very high revving engine like in an S2000, I think it's clear that running low RPM's will eventually build up carbon or whatever but D17's redline at around 6800 (at least my tach says so) so carbon buildup may not be as evident in lower RPM engines.
While I agree that occaisionally giving the engine a good rev now and then is good for it, I don't agree that it's something you should do all the time.
On the subject of shift points, the amount of load placed on an engine in 1st gear is not the same as the amount of load placed on an engine in 3rd or 4th. Basing shiftpoints would be best determined using torque/power curves rather than on strict gear ratio vs. a single torque/power curve.
Torque/power curves are not indentical irrespective of gear. Engines behave differently under different loads.

Rep Power: 0 Honda's originally made motorcycles didn't they? So essentially, redlining shouldn't be a problem, even for non-VTEC engines so as long as u don't do it on a constant basis rite? I mean, Honda's can take it way better than Ford's anyway.

Rep Power: 286 Its common practice to "blow out" your carbon deposits especially for those who deal with alot of traffic(idling) or short trips(like to the store, dropping off kids, etc). Idling and short trips where the engine, intake/exhaust systems never get up to full operating temp or build up enough heat to clear out any condensation in the exhaust is really bad over time. Its good to every once in awhile to get it warmed up to operating temp and take it on the highway and run it hard for a few passes. For instance my wife's minivan is primarily used for a grocery getter/school bus and rarely see's any highway time during the week. I make it a point to take it on the highway on the weekend and punch it a few times to clear out the build up. You dont have to redline it, but take give it a good romping so it drops into passing gear and hold it for few seconds. For my 5-speed EX, once a week during my commute I run it up to a high rpm in either 4th or 5th gear after everything is stabilized.

As I already said, the shift points were calculated for MAXIMUM ACCELERATION. IE, racing, drag strip, etc. Obviously you don't redline every damn time you drive the car. lol
Secondly, yes carbon buildup occurs on ANY engine. A healthy dose of some spirited acceleration CAN help knock loose some of the carbon deposits, which you'd then see burned out the exhaust in a puff of black smoke.
And even if it DOESNT knock the carbon loose or out, it's not hurting anything anyways. There is nothing wrong with accelerating briskly or even all out every once in a while.
this is not research I've done myself, but merely passing on words from those who knows more about honda engines than probably all of us combined.

Rep Power: 0 i like how people dont realize the redline is there because that is the brinking point of doing damage to your engine, and they dont realize hitting it isnt bad. I mean if it was bad for the engine, dont you think the car manufacturer would make the redline lower so not to damage the engine?

Rep Power: 375 if you beat the snot out of it all the time, yeah that's going to do more wear and tear than babying it. that goes for any car, any engine, any manufacturer.
but that doesn't mean you can drive a little spiritedly and have a little fun now and then.

Rep Power: 787 rofl, i've been to redline a few times in my auto, and I was not even flooring it. Seems like it would've kept going too if I didn't let off. By redline I assume you mean the red part on the cluster

Okay, i hardly ever do this, but I'll admit once or twice... I heard somewhere it's good for the engine

Rep Power: 375 revving the engine way up to redline while the car is in neutral is bad for the engine since there is no load.
