Default what rpm do u shift at?

Hey just curious to see what rpm people are shifting at while dd, and what rpm they drive around at? I shift at just over 3k and Cruz at around 2.5k just wanted to see if this is normal. Srry if this has been asked I'm at work on my phone kinda hard to search well.

During DD I keep my foot out of it to never go too far above 10inHG on the vacuum side of the gauge, rev to no higher than 3000RPM and try to keep myself in the 1800-2300 range while cruising, this of course is unless I need to get the hell outta the way really quickly. I'm sure it annoys the people behind me to see a WRX with exhaust on it putting up to speed as slow as I do, while I'm being passed by old ladies in Toyota Prius'...Priuses???...Prii??????

Anyways, yeah, slow, but I don't seem to notice much of a difference between driving like that and getting after it a bit up to speed, other than maybe 1-2mpg strictly city driving.

I normally shift around 3k rpm in the morning during warm up, but normall shift around 3.5k-4k driving normal, keep in mind I have an v8 ej207 motor so the powerband is a little different. The v7 motor that I had under 3 grand the car was hopeless

I normally keep it below 2500 until my oil temps are OP temp. then i shift at around 2800~3000 for DD... On ramps are another story though

Shift rpm depends upon how aggressive I'm speeding up which depends upon the throttle percentage. Throttle percentage will create a natural power band that is different from different percentages of throttle. For example, light throttle will typically choke out above 3k rpm. You will feel the power drop, and that's a natural time to shift. You press down the gas more, and the power band shifts some. During full throttle, redline is the ideal shift point given the power band and gear.

Most of my mild cruising with partial throttle has me shift between 3-4k rpm. Where I shift specifically only has to do with the power band at the throttle I'm applying. When the power output rolls off, I shift.

I try to keep my shifting between 2k and 3k for DD. If I'm revving up I'll let the tach hit around 3k and then after the shift I will try not to let it drop below 2k. Otherwise you're eating up fuel trying to get up to speed at low RPM.

When I'm cruising around I try and keep it about 2.5k

Daily driving = 2000-3000rpm
Anything over 3000rpm = passing/merging / spirited driving.

But seriously, we need a 6th gear. :P

i shift at 2400-2500 for normal driving... but in first gear i shift just a little over 2000.

for passing someone i usually go up to ~3200-3500

love low end torque


...and unless you are in 5th gear.... you shouldn't be cruising at 2500... that's a bit high for cruising in gears 1-4... but I guess it also depends what car you have. When I cruise in 1-4 ... I keep it at ~1600-1800

So you're cruising around at 1k RPM higher than idle?

Then you're just guzzling gas anytime you have to go up hills. Either that or you're doing a lot of shifting / downshifting for passing etc.

It probably also depends on the terrain, but here in Seattle there's so many hills and curves and turns that it doesn't make sense to cruise that low. There's no power down in the 1600 RPM range, and anything other than a flat hill is going to gulp gas.

yes, there's nothing wrong with cruising at 1k RPM above idle.

if i'm going uphill then that's a different story. i can tell if my motor is struggling.

if I have to make a pass, then I just downshift 1 gear which puts me at like 2500-2900... how hard is that?

if i know that i'm gonna have to make lots of passes for whatever reason, then i'll keep the RPM high during that time

and it doesn't matter if you dont have power in the 1600 range, you dont need that much power to maintain a constant speed.

if you're the type that is scared to shift/downshift then by all means cruise at 2500 and look like a rookie. we don't drive hondas, our motors actually have torque.

I realized that you and I are talking about apples vs. oranges. You drive a wrx while I drive a 2.5i. Your car has so much more low end torque than mine (turbo). That accounts for a lot of the power band difference, and why you drive in a lower RPM than I normally do.

You know our cars "cruise" at about 2500RPM at 60mph right? That's how subaru engineers designed our car, to run optimally around 2500RPM cruising speed....

And I'm not a rookie

So you're a big fan of lugging the engine?

If you love the low end torque, you'll love it even more if you actually go up to (and beyond) peak torque.

So what do you think you're gaining by driving around with RPMs that low?

You're right. I do it all the time... in my LS6-powered CTS-V, which has develops more torque at 1500rpm than a N/A EJ25 develops at peak torque. In a small displacement 4cyl there's nothing to be gained by rolling around at 16-1800rpm.

I hate to break it to you, but the EJ25 is still just a N/A 4cyl. Yes, it's designed to provide a bit more low end than most inline 4s, but I doubt I would drive a Honda 2.4L or Nissan 2.5L or Toyota 2.5L any differently than the EJ25 when it comes to day-to-day driving.

As for when I shift, I'd say my driving style is about the same as Back Road Runner's. I guess that makes me a rookie.

prime example that member # doesn't mean anything.

something tells me you've never driven a WRX 2.5L but just like to run your mouth.

and research: torque vs peak torque

Hey its better than Tom "cruise" you know? haha anyway when I'm trying to save on gas I cruise at 2k and shift at 2.5-3k never going above 3k unless on interstate. I never go above 6k even when I'm farting off and even then I've only been that high a few times.

I'm a little confused by what your trying to say, but the turbo shouldn't have much effect on low end, check out some dyno's and you will see what I mean. Maybe if a roots or screw was installed this argument could be made

For dd, I normally shift at 2800-3000 or so. But when the engine is still warming up I'll take it easy and shift at 2200 or so until it gets close to operating temperature on the gauge so as not to induce any extra wear. But when the engine is good and warmed up, I'll shift any where between 3k and 5 k depending on where I am driving, but mostly 3k or so. If it is an on ramp I'll go right up to 5200 or so in gears 2 and 3 if I need to book it, if not then I'll shift at closer to 4k in 2-4 with about medium throttle. My car has 182,000 some miles on it right now but still gets up and goes though...lol I am using the shell T-6 oil in it and about to do a 3rd oil change using this oil and so far it runs good with it.
