ya well I do too. May want to get a tranny cooler if you do alot of that kind of driving.

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: 812

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.

you guys are killing me AutoX ones a month and some of that greased lightning would clean some of that carbon off

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.

hahaha.....this is hilarious....there are gonna b a bunch of 7thgens in shops or junkyards.....just keep in mind.....D17=slow...hahah ur still not going to beat that WRX or EVO that you always wanted to

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.

 
Rep Power: 319

I had a car that needed leaded fuel...

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.

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.

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.

Any additives you guys use?

I was thiking of putting fuel injector cleaner next time I fill up. I got about 22k miles.

fp60 from lubecontrol.com is the only additive I would use now.

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.

I think you are misinterpreting my posts.

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.

use Seafoam that will clean out carbon deposits. Don't do it though if your neighbors are the type that would call the fire dept. if there is ALOT of smoke LOL.

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: 0

i dont have a tach,..but im sure if i did i would redline every so often,..atleast 3-4 times a week

So you're telling me that driving my car fast is not going to "rag it out" any quicker??? yes or no?

it's an auto, so i can't redline.

 
Rep Power: 400

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: 273

Yes ofcourse, that's absolutely impossible. The automatic transmission simply won't let you even come close to redline, ever, under any condition and without exceptions.
It would take an absolute mechanical miracle for that to occur.
Now where on Earth is my sarcasm smiley?

 
Rep Power: 812

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

 
Rep Power: 334

the automatics can hit redline, but rarely. once it hits that 6900rpm mark, it shifts itself. i doubt it'll never go past 6900rpm unless you have it modded to.

 
Rep Power: 0

it is the same philosophy as the two asprin dose. Most people can take 20 before they are in danger of dying, but a few who drink, smoke, and are just old will be in danger after 3 or 4. Alot of people run their cars to super high rpms daily (**cough cough** me) and will never have a problem, but some who use shitty oil, have old *** cars and don't take good care maintanance wise will blow thier engines at 7k rpms. And that is why civics have a rev limiter at 6,900 rpms so even jackasses who don't know d!ck about cars can have fun.

 
Rep Power: 273

...or if you put in in Neutral. Am I the only idiot that does this? Is this not "true redline" unless the drive is engaged? I mean the engine is still whirring away like crazy, even if it's not pushing torque.

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

 
Rep Power: 400

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

 
Rep Power: 812

revving in neutral is very bad for the engine.
