I noticed when I'm driving 60mph my rpm's are really high at 3000. Is it normal and safe to run at that high. And is their anything that i could do to my car that would lower them? It's weird to me becase I am used to a v8 engine.

 

you could always swap out the final drive gear for a wider one... it's just the nature of the Close ratio transmission.... mines the same way and i don't think a constant 3k rpms could hurt anything...

8000 on the other hand.

 

3k's nuthin my 4spd tercel cruises along at 3500 at about 70 and it only revs to 5700 rpm!!

 

well im at 4500 rpm to work everyday , wont hurt anything plus warrenty some ***** will run a red light and crash your car faster prolly

i cruise between 3800-4500 everyday to work doing 80-90 mph on the highway... no problems after 10k miles

 

Same with me I don't got that many miles yet.... But i cruise around 80-85 to work everyday and nothing.... You gotta remember your in 5th and that's a long long gear.... your rpms aren't going to go up very fast so your actually not that deep into the power band at that gear

 

You should try staying below 3500rpm (MIVEC) to see how much it'll help your gas mileage.

 

which is hard to do on a 65 mph highway.

 

It's normal for a revvy 4 cylinder. Mine, at about 65-70MPH (auto) is just over 3000. Not bad actually and it really helps acceleration, having tight gearing like that. V8s, most of them, don't like the area after 5000RPM and most of their power is low, so makers gear V8s to run low RPMs, the opposite is true for 4 cylinders, you want to get past low RPMs as quickly as possible, thus the fast gears.

 

Yes.... especially now with gas so damn high....

 

sooo true, i got gas early... 2.59 a gallon

 

Yeah, it's pretty hard to stay at 72mph. That's why I wanted a "warning" LED that turns on when MIVEC's engaged. I usually keep it on cruise control now, and pray that there's some traffic so I won't get "pushed" to 80mph.

 

Remember that you're dealing with half the number of cylinders doing the same job as your v-8 used to, plus the fact that 4 bangers make most of their power in the top end of their rpm range. A normal V-8 makes it's peak power a few thousand rpm's lower than a 4 and has a lower red line on average. In case you haven't read the noob thread, MIVEC doesn't "kick in" untill 3600 rpm and that's when the engine really starts to make power. Don't worry about rpms untill you get up around 6500rpms...
p.s. you won't get there in 5th gear anyways because of drag limitations!

Be happy, rev freely!

 

Um... i've been over 130. and thats about 6800 rpms.

 

i get about 27-29 mpg... even when im cruising in mivec.... it used to be around 24mpg but i guess my engine is broken in...
