Redlining

[Spectre927]

I have a 96 GSR, with about 108,000. The engine looks good, and sounds good and i got new radiotor, new water pump and timing belt/acesory belts and do regular maintenance(3,000 mile). I always hear redlining is bad for your engine, which makes sense, and so is driving 45mph in 5th. Is it just as hard on your engine redlining it in 1st as it is in 2nd, or 3rd, or any gear for that matter? Seeing as how its such a wonderful sound, I can't help it. How many times a week, should I try and keep it down to, so that I don't blow my engine or anything harmful? I hope I don't sound too ignorant, but everybody has different experiences, so Im trying to see what the majority opinion is about this.

essentially never redline your car when there is no load on the car. If you really want to stretch your rod bearings n bolts then be my guest but other than that its okay to accelerate to redline once in a while just not at everychance you get. And by no load I mean that the car is not in gear. There is no point to doing it other than to be ignorant and break stuff (but it does sound cool ill admit that). Just drivng and shifting at redline wont kill your car. When you race or are trying to accelerate as quick as possible then shift more towards redline If I had a gsr and was going all out id probably shift around 8,200rpm (just my 2 cents so dont take my word for what you should do- every car and driver is different)

yeah, don't redline in neutral. I don't think it is SUPER bad to redline, just don't keep it up there and dont drive at like 5000rpm just holding it there. I heard redlining cleans carbon deposits off your valves though

Is it bad to bring my 98 ls up to about 6000 rpm in neutral???

[TegLs]

O and at what rpm would my 98 ls wun accell no more??? i always shift at around 6800 rpm...

[92acuraattack]

well Im not sure about the later integra non vetecs but in my 92 teg I can shift at 7300 no problem and I believe the revlimiter is around 7500
however do not test where the revlimiter is when its not in gear because the engine can go to a higher rpm than the revlimiter on its momentum (plus its just bad for it)

when accelerating try shifting at around 7000-7300 (my advice)

OO driving in 5th gear at around 45 mph is bad for the car???...i think i usually use 5th gear at about 50 mph or so is dat bad

I've heard its better to overwind it than underwind it, in other words if your not sure what gear you should be in go to the lower gear. Some one told me its just as bad to drive in 1st gear at 7k as it is to drive in 5th gear at 1k. Thats just what I was told. Seeing as how we have so little torque, I can see how it'd be difficult to get a 2500 lbs car to go in very low RPMs.

[Spectre927]

The basic rule is a gear for every 10 mph, so 50 in 5th wouldnt be too bad, except never cruise in 1st, I go from near dead stops a lot while in 2nd, but my car at 45 in 5th doesnt have a healthy sound, and a school bus could probably out accelerate me.

[TegLs]

On my Ls i usually shift at 3-3.5 rpm on my normal driving and those are good time to shift rite???

[92acuraattack]

well it depends on how fast you want to accelerate and you will know when to shift at what rpm and mph the more you drive and become familiar with your car. around 3500 and above is normal.

and I agree 45 and 5th gear = whoa holy high gearing batman we need to down shift or the joker will get away in his school bus for sure

I have a '92 gsr and i just can't help reving it right up sometimes. I don't know how someone could just cruise around in there 'teg and keep it under 5k because quite frankly at commuter speeds in my morning commute i get over that in 5th gear. If i am accelerating it depends on the situation, but normally i shift around 6,000. If there is a lane merge and an asshole to the side of me, well then i shift at 8,000.

[Spectre927]

Well I have some modifications to it, not too big a deal, but from 1 to 3k rpm it sounds normal, not too loud, but after that it sounds loud and just by the sound people think Im like racing them. Its weird because after like 3500 rpm, I can't hear the exhaust, and all the noise is coming from the engine(vtec 5.xK rpm and up) and the intake(6k and up), buts still hella loud. I love it. I don't really like the attention it draws. You never know when a cop might be around.

i drove a lexus is300 the other day and all i can say is damn. it has like 2x as high gearing as our tegs. going 45mph in 2nd gear you are at like 2800rpm, in my car im 48mph @ 3000rpm in 4th. and it still has sooo much acceleration in the IS300, you get up to speed so fast so easily.

You guys sound like a bunch of F&F wannabe's. No offence but what are you guys talking about? The reason it's called the redline is because it's not good. You guys can't possibly take it into the red anyways. That's why Honda and most other automotive companies have rev-limiters. Unless you have a chipped ECU you are not even in the red. The only motor I know of that was made to ocassionally hit the red is a rotary and seeing as we all have piston motors we should never see it. I have a chipped ECU and my valvetrain is not built yet so when I push it I constantly watch the tach as not to float valves. Oh and the whole 45mph at 5th thing, the only reason you guys say that is because you guys probably have LS's. Drive the short gear ratios of a DOHC VTEC high rev engine and tranny and you'll think differently.
