I'm wondering what kind of RPM I'd see while cruising on the freeway at 65mph and 80mph. I remember my old LS was about 2900 for 65mph and 3500 for 80mph.

Thanks!

Stock, at 80mph im around 4300rpm in 5th.

 

Assuming a stock tire size and stock 4.4 FD.

 

Yikes! Is the engine able to take this? Or am I going to have to modify my highway cruising speeds?

Also, does it make it hideously loud, then, to cruise at 80mph?

 

My cruising revs at 80 is 5000 rpms.

 

I guess. 76K and counting. Turn at least 4300 rpms for the majority of my daily commute to and from work (30 miles each way). Over 30mpg last tank too. Burns a fair amount of oil, but still compression checks and runs great.

Yup, its about 4200-4300. It doesnt bother me at all, you get used to it. Sometimes I even turn off the radio and just listen to everthing working in harmony.

Its funny though, whenever Im driving my non-Honda friends on the highway, they invariably ask, "are you in 5th??", "are you sure??" hehe.

 

Why do people think that 4k is stressful on the engine?

I am at over 4500k on the highway almost all the time. I get 30+ mpg, sometimes 35 on the highway.

Hondas (most of them at least) are meant to rev. In the scheme of things 4500 rpm on the highway for 8 hours is much less stressful than constantly (100+ track miles) being in VTEC (6-8400rpm) at the track at WOT all day.

 

Thanks for the replies guys. I guess it was something I just overlooked when looking at the ITR. Is it so loud that it drowns out the music or is it okay in that respect? I came from a car that was *very* loud, an old Austin Mini, so I'm somewhat desensitized...or so people tell me. Not to mention completely desensitized to stiff ride. Anyhow, the biggest concern I had with the old mini was it became labourious over time to feather the throttle because the car had a *way* over spec horsepower (85 vs. 55-60). That may not sound like much, but remember the car weighed in at around 1250lbs and we're talking about 1960's technology engines with sloppy fuel systems, only 3 main bearings, and what I would characterize as not the most efficient ignition systems ever...coupled with it only being a 1275cc engine .

Anyhow...I digress...I'm just concerned with comfort in a long drive as my mini was NOT. I used to own a 1995 LS, as I'd mentioned, is it fairly comparable in this respect?
