hey guys i cant seem to find an answer to this question. As u guys know, when driving a prelude (city or highway) the motor seems to stay around 3k RPMs. This is usually higher than most cars (around 2k).
but what i've been searching for and can't seem to find the answer is:

1. Why do prelude RPMs sit higher than most cars, when being driven? would the tranny have something to do with it?
2. is there anyway to lower the RPMs when driving? of course a way which would be safe for the car and be able to DD
3. Do all prelude engines (H22 H23 F22 etc.) idle like this?

i'm not a mechanic or anything but i just like to know bout cars and if anybody could clear this up for me i'd appreciate it much

Thanks!

ive been told that preludes are more geared towards performance thats why they run so high. mine runs at 3500 at 70 m.p.h. at least give me a 6th gear for economy.

thats normal you have nothing to worry about
mine runs about 4500 rpm @ 80 on the freeway
about 3500/3700 @70 mph on the freeway
these are geared towards performance
get you a nice exhaust and enjoy the hum and guzzling of gas when your on the freeway!!!

not to be a dick, but this has been covered like dozes of times

1. Why do prelude RPMs sit higher than most cars, when being driven? would the tranny have something to do with it?
yes, its all the transmission. its how the h22 trans is geared
2. is there anyway to lower the RPMs when driving? of course a way which would be safe for the car and be able to DD
yes, you can do a transmission swap. or swap in an f22 5th gear because they are longer
3. Do all prelude engines (H22 H23 F22 etc.) idle like this?
no, they dont. in order of shortest gearing to longest. h22/h23/f22

Last, most small-displacement sports/GT cars are geared just like this, using a close-ratio gearbox to keep the revs from dropping off too much when shifting up. Back when Lucas, Prince of Darkness, ruled the Earth and all engines were mounted north-south, many European cars could be had with optional, strap-on overdrives -- literally, a reduction gear with a hydraulically or electrically-actuated clutch, that attached to the back of the transmission, engaged by a switch on the gearknob. That could be used no matter what gear you were in, so the average four-speed became a seven-speed (using in first gear was unwise). American cars and some trucks up through the '70s had a similar setup -- the station wagon I learned to drive on had a big T-handle under the dash marked "Overdrive"...I was told if I needed it, I was going too fast. :) Now it's just easier to add an extra cog to the standard 'box, and that's what the top ratio is on sedans and the like. Our Element (with a 2.4 liter 4-banger) does 80 at about 3500 rpm...but better kick it down a gear before trying to accelerate!
