Thats not high RPM's at all. Gas/Petrol engines, especially 4cyl engines like to rev. They make power at least around 3000 rpm. Climbing a hill at 3500-4000rpm is no big deal. You'll be fine. Hit the pedal and GO

 

Something there seems to be off. RPMs's to MPH is linear as in every Y amount of RPM equal X amount of speed increase. So iff at 2100 RPM's your doing 55 and at 2200 your doing 60 then at 2300 you should be doing 65 not 2700.

 

I didn't notice that, looked right past it. Are you SURE that 5th is higher RPM than 4th? Try it at 50mph.

 

THanks for the replies everyone

I am not quite sure what you guys are saying between the 4th and 5th gear, should I go 50 mph in 4th and 5th and see which has lower RPM?

About the linear increase, it seems like a standard increase in engine speed, my numbers might be slightly off and the car runs smooth as could be I am just worried about running the car at 2800 RPM for a few hours at a time on the highway...

2800 RPM seems too fast to spin the engine at for multiple hours, am I just a worrywart or is that too fast for 65-70 mph?

Thanks again all!

Don't worry about it - 3000 RPM is nothing to this engine. The power curve actually has a sweet spot at around 3500-6000 RPMs. Max torque is at 4400 RPMs, max HP generated at 5600 RPMs.

That said - assuming that you are in 5th gear with OEM transaxle, tires are the OEM size (185/65-14).

Your engine speed should be as follows:

2086RPM @ 55MPH

2275RPM @ 60MPH

2465RPM @ 65MPH

2655RPM @ 70MPH

There might be a slight variances due to gauge resolution, but looks like most of your numbers are within the ballpark.

Running the 1ZZ-FE engine at 2500-3000 RPMs is like idling a small block Chevy. No stress at all on this car/engine - like you said, you're just used to lower RPMs.

When I tow a smaller trailer on long grades - I routinely hit 4000+ RPMs for hours. No issues at all, over the 200K+ miles that I've driven my Corolla.

Just make sure you wind out out the engine a bit when shifting, since its sounds like you are used to shifting at lower RPMs, as that low RPM lugging can be harder on these higher revving engines than bouncing off the redline.

 

Don't worry about it, lol for the people like me with the 3 speed auto 75 mph is 3500 RPM. so it's hard to cruise any higher than that when you have to hear the motor turnin that fast. I usually travel the interstate between 60 and 65 mph in the right lane of course haha.

 

These guys are right, let'er rip. Idling or lugging an engine is actually more harmfull to an engine then some revs. BTW, those speeds in 3rd gear is where some acceleration is at.:clap:

 

I think mine revs at about 3000 at 80. Here in Colorado, many sections of Interstate highway are at 75MPH, and I usually do 5 over. I wouldn't worry about it, 4 cylinders like to rev. Heck, my Mom's V6 Avalon likes to rev. FWIW, I used to drive an 86 El Camino with a 3 speed transmission. At 80 it was at 2900RPM and I would drive like that for hours and it never hurt anything. Gas mileage wasn't any better doing 65 either.

 

I once had a 1990 Toyota pickup with the 3.0 V6 and a 5 speed. Drove up a big summit in 3rd gear around 4500rpm the whole way. Got horrible gas mileage, but didn't complain any

 

My 7th Gen reved the same range. Still confused how 3000rpm at 75mph with my 95 5 speed can get better gas mileage than the 2300rpm auto in my 2000 at 75.

 

Thanks for the replies everyone, I just wanted to make sure I wasn't going to damage anything

You all have a very kind community here :rockon:

 

Better to be safe than sorry. But yes these little 1zz-fes love revving. You'll enjoy it I am sure
