Shifting RPMS?

Hey all... just a quick question. I'm a n00b here, mainly because I just bought my '03 P5 a month ago, but I've got some questions on how you all run your P5's. 1st I guess is, as a daily driver do most of you start off around 1500 rpms? Then I guess the next question would be, to conserve gas you prolly want to shift around 3500 rpms, right? But, if that a$$hole in the Civic next to you thinks he can take you off the line, how far up do all rev your engines before shifting gears. I've ran mine upwards of 6500rpms before shifting and I guess I'm curious what everyone thinks as far as wear and tear on your engine goes. Aiiight. Shoot me if this is in a different post.
 
i shift like 4000 when im just crusin, ill run mine up to 6500 or a bit over if there is that civic case, im drivin a msp tho

rev limiter is at around 7200rpms. i've hit the rev limiter before.


wait, u've hit 7200 rpm?!?! not on stock internals, right?

Take it easy for the first 500-600 miles or so; while "traditional" break in isn't really necessary, it's still a good idea to do so.

Second of all, forget about the Civic. 6.5 grand should wait until you get some miles under that engine.

Personally, i could care less what most people are doing around me, but generally I'm shifting around 3500 or so, unless I need to accelerate for the intersate, etc - I'll top her out at 5500 or so then. No more......you don't make much power beyond 6500 anyway, so save it until you have some mods that'll open up your top end...
 
Awesome. Thanks guys. I (unfortunately) didn't get 'er new so she's got 30k on it right now, So, I'm not too concerned about the breakin period. However it's good to know that it is essentially pointless to rev it up that high if my power is tops out earlier than that. I feel better about giving it my own "limiter" at 5500 or 6k. Thanks again. Sorry for the lame post.
 
Daily driving, shift at 3500-4000. Racing. shift at 6. There is no point reving to 6500, you still drop into your powerband shifting at 6. Look at some dynos and watch the tach when you shift, you'll be suprized.
 
power in these cars peaks at 6000rpm. torque peaks at 4000rpm. no point in going beyond 6000 and especially into the red unless you like things blowing up(if done numerous times).
 
For fuel efficiency I shift at 3000 rpm in first through fourth, and into fifth at 2500rpm (40 mph). I've averaged 24 mpg so far with a high of 28 mpg last week -- the average is low because the dino oil didn't like the single digit temps in Dec. and Jan. so I got 20 mpg then. I'll see if synthetic helps that this winter.
Oh, and shifting like this keeps me moving with traffic, so I don't drive like grandma.

For performance driving, keep the revs between 4000-6000 rpm and you'll be good - not fast, but good. Reasoning is this: 4000 rpm is the torque peak and 6000 rpm is the HP peak. With our gearbox, keeping it there is easy.

You have to shift at 2000 2500 rpm to get the stated 25/31 mpg. It is really boring to drive like that but that it what you have to do to get it.
 
I shift between 3500 and 4000 in normal driving but when I want to give it a burst of acceleration I go to 5000 maybe 5500.

When there's traffic or cars in front of me that don't accelerate much I shift at 3000.

i've done it 'numerous' times.
i'm still sitting here with an engine that runs day in and day out just fine.
 
Yeah the rev limiter is there for a reason. If running the car to 6500rpms would cause damage, the redline would be only 6000 and the rev limiter set lower.
 
Noise does not equal power. shift at 6k people! :p the car has alot more "shove" when shifting.
