I was wondering what damage driving in high RPM's causes to your car. I
taught myself how to drive a manual but pretty much assumed you always
shift around the 3.

Thanks,
John

If your vehicle is a Honda then its a high compression 4 cyl. or 6 cyl. High
compression engines work best at higher rpm's, I usually shift my 89 Accord
around 3,500 to 4,000 rpm. If you had a older V8 Chev or Ford you would be
shifting lower because your working with lower compression.

I can only talk from experience but here is what I know. I have a 94 Sentra
SE-R with almost 120,000 miles on it and I have probably hit at least 7,000
RPM every day I have had it(Redlining is 7500, which is probably every other
day). I have never replaced anything in the engine, not one single
thing(not even timing belt). I once needed a new battery, but that was my
fault(left lights on). my car is as fast now as it has ever been and runs
as good as the day I bought it, albeit not as smooth or quiet but 120,000
miles is allot. I seem to think maybe it is good for the car to rev it out
every once in awhile. With today's light cars with small engines your not
even getting to the Max HP of the engine shifting at 3,000 RPM. Just my two
cents, don't blame me if yours blows up.

I've driven a stick shift for 5 years and I've always shifted around 3-3.5.
But the red line on that car was at 6. The red line is usually a very good
guide for me.

What 3? Like the 3 on the tach, as in 3000 rpm? That's probably safe, and
adequate for tooling around town. For faster acceleration, you'll want to
shift at higher revs, but don't exceed redline!

Compression has noting to do with it. Diesels us about 22:1 and turn
very low rpms, 2000 is about max. for most.

Shifting around 3000 is fine. There really is no damage if you rev high once
in a while (lets say you want to get aggressive a bit). Basically you should
be able to go to redline without any damage as long as you are not there for
an extended period of time.

If you do decide to drive aggressivly then you should do oil changes a bit
more frequently.

PS. My mustang has a redline of 5900 but on daily driving I usually just
shift around 2000 to 2200 rpm but if I need to race someone I usually end up
shifting around 5200. I can get away by shifting around 1800 but the car
feels pretty sluggish so I only do this if I am real low on fuel :)

Also, if you drive with the RPMs too high for a sustained amount of time, you
could have oil starvation set in on your engine... But that would be if you
drove at your redline for a few miles.

I'm talking about gasoline engines here and I'm sure John Eustice was as
well. What do you shift your GASOLINE fueled high compression vehicle
at, 2K rpm?

What kind of Honda (assuming it's a Honda) are you driving? If it's one of
the newer 4-cylinder models, shifting around 3 is very low.

I have a '99 Miata, and a good shift point is 5500 rpm, although shifting at
7000 rpm is fun from time to time. It's also harmless. The same should be
true of the 4-cylinder Honda's, although you might want to check with a
guru.

You're kidding me right. What, you're afraid the engine will blow up if you
take it past 3K? At your shifting rpms, you get jack for torque, you foul the
plugs and get crappy gas mileage.

You have got to be kidding me. 2k? What are you reserving the
other 4500 rpms for?

When I drive my '92 Accord, I usually shift around 3 to 3.5K for
normal "blah blah' driving. 4 to 5K when I feel a little frisky,
and 6K when I want to pull ahead of something real quick.

Right! On my '83 1.3 litre Civic FE, the orange light comes on at 2,000 to
recommend shifting up. This was a Fuel Efficiency (FE) feature for that
model. I consider it to be good driving ..... but on the roads I'm in the
minority. Mind you I'm still alive and driving an '83 Civic.

Jeezes. You're joking, right? Maybe if you're driving for maximum
fuel economy.... These motors are designed for best torque around
4000 RPM's. You KNEW that, right?

To drive a Honda automobile and never rev beyond 3,000 rpm is ridiculous.
Every current Honda/Acura car, even the 3.5RL, makes its highest-rated
horsepower above 5000 rpm. Never "cranking" it means you never use the Honda
horsepower you bought and which was advertised/promoted by Honda. My
soon-to-arrive Prelude VTEC kicks out 200 bhp at 7000 rpm. Heck, the VTEC
changeover doesn't even kick in until post 5000 rpm. And I intend to enjoy
my 200 bhp....

Of course, even though I've already had five Honda/Acura cars and 1 Honda
bike in splendid shape after daily high revs (all in family hands or
otherwise still going strong despite the cars being at least 8 years old),
one never knows what might happen to your engine. Just in case you have a
bum engine or some other bad luck, you understand!

I would think shifting at such high RPM's would cause you to have clutch
problems earlier than normal.

I think about 80% of clutch wear occurs starting from a dead stop. If you rev
it high and let the clutch slip a lot you will definitely increase the wear on
your clutch. But running it up to red line in gear, then shifting smoothly to
the next gear would have negligible effect on clutch life.

How much do a sports clutch cost ???
Maybe I will not brought a Vtec engine but not using the vtec
only because I have to save my clutch from wearing earlier!
Vtec power (the quick cam) intervene or changeover on 5000rmp
or even higher, and the vtec engine can bear 9000rmp or more!
you know !check your Vtec handbook!

And you'd be wrong. The motors are designed for the higher RPM's.
I'm always amazed with people who think that they know more about the
motor's safe operating area than the Honda enggineers do.

He may have a point. The only problem I've had with my GSR is a
broken clutch spring. And it broke when I downshifted from 5th
to 3rd (about 3000 to 6000 rpm) which is something I do regularly
when I pass on two-lane roads. I wonder whether all those rpms
might have contributed.

Well,but we are talking about DRIVING in HIGH RPM but not
safe driving!
And I don't think driving in high RPM equal to dangerous driving!

Clutch springs usually bareak because of improper shifteing: Jerky, hard, or
clutch drops etc.

Down-shifting from 80km/hr is the most fun...Forget 3rd gear, go all the way to
2nd. Also, If you can't sink it, then don't bother, just take your time and
merge like the rest of the sheep's ....it will save on clutch spring.

That's pretty high for a downshift. Why not wait for an opening in 4th gear
and then downshift to 3rd?

Come on Honda VTEC engines are racing engines. Have you ever noticed the
REDLINE goes to ... 7000? There is a reason for that.

I suggest that you MUST have a sport clutch kit !
I usually downshifted form 4th to 3rd in about
6000 to 8500 rpm in fast cornering to keep a higher
rpm , and my integra Type R can reach 10,000 rpm
after modification!!!

Third gear is good, when I'm feeling conservative, but I like kissing the
redline. In second gear I can reach 120km/hr.
