High RPMS
 

hi guys
i have noticed that on the highway my car uses more fuel than city. when i do city driving i get around 500kms/full tank. if i do highway driving then i get around 400-450kms/full tank. well its a 96 integra rs, b20b, 5 speed. on the highway the rpm reaches 3500 rpms at 120km/h, dont u guys think thats a bit too much? my 98 civic automatic tranny reaches 2700-3000 rpms at 120km/h. is there anything wrong with the car?

thanks

lol the higher the rpm the more gas you burn ....common sense bro

i know that part dude. (more rpm burns more gas) some cars get better gas mileage on the highways compared to city drivings. anyhow my question is, is it normal for a 4 clyinder b20b to have 3500 rpms at 120 kms?

Are you for real? It has nothing to do with the motor you have. Its the tranny.

Its not a grand tourismo video game that you can tune the gear ratios.

Man the quality of posts on here has really gone downhill, almost everyone is a signature candidate for stupidity that I can use on offtopic or supraforums... :rolleyes:

sounds normal for the rpm/tranny combo.

you should be getting better fuel economy on the highway though. if i just cruise on the highway i can get over 550km easily. in the city my car is horrible. around 350-400km.

just make sure your engine is up to proper tune. and your o2 sensor is working correctly. and last but not least you now have a 2.0L engine in a car with a ECU programed for a 1.8L engine. is it properly tuned for that?

you get better gas mileage on the highway for the very reason that "most" people stay consistent with there on/off throttle inputs compared to the city where you don't have a choice because of stop lights, stop signs etc

Exactly.

120km/h at 3500 for a B20 sounds right if you have an SIR tranny. at 130 my RPM is 3500, larger speed same RPM, but my tranny is longer resulting in less power being used from the engine.

100 kph gives me 42mpg+ @ 2700'ish rpm

140 kph gives me 32mpg+ @ 3900'ish rpm

my final drive has me doing 4500 rpm at 130 kp/h haha don't complain...but i love torqueeeeee

ppl come here looking for advice, especially in the tech section. not everyone has an advanced education of cars, some don't even have a basic one. that's the purpose of this section.
when you were growing up, did your teachers say "you're stupid for trying to solve a question or asking for help" ? no they didn't, they educated you. if you don't like what you read on here anymore, don't come here. nobodys forcing you. even if the quality of posts here are going downhill, attitudes like yours don't help it at all. you don't even contribute enough to this board to even matter anyways. what's the point of you being here?

^ +1
I concur.

qftmft!!!!!

Lol yea you have a s1 or j1 tranny im running about teh same rpm @ 130. i ca get anywhere from 300-550km a tank all depending how i drive

QFMFT.. some people should just know when to shut up. If you love supraforums so much.. stay there.. im pretty sure you being here is just a waste of yours and everybody elses time. help other members when they need the help, dont put them down just because you know more. now smarten up or GTFO!

thanks a bunch guys for the input/tips/replys. i feel like an idiot when i ask cars related question but to be honest this is my first car and until now i didn't even know what radiator and stuff were and because of many helpers on this forum i have learned a lot about cars compared to before. anyhow i wouldn't like to create another thread i'll just ask one more question here. my car has got over 200, 000 clicks on the engine, its 5-speed and i was wondering if it could manage a roadtrip to Montreal. i have planned to take 30 minutes break every 2 hours to let the engine cool down a bit. last i remember when i drove it to Kingstone the steering wheel started making some weird noise and next morning i woke up drove the car and the weird sound from the steering wheel had gone.

thanks

You don't have to be sorry for asking any questions. You're a part of an Integra forum and you have joined it to learn new things. We're more than happy to help you out. But we still ask that you do your research before posting up questions or starting a new thread.

If your car has 200,000 clicks on it, when was the last time the timing belt and water pump were changed? If there's no record, I recommend you get it done.

yea man... no need to feel stupid... that guy is just a big penis lover. BUt I dont think theres a need to take the breaks. Just do ur tune up, make sure everything is running fine (no weird sounds) all fluids are topped up and that should be it. and for a Honda motor 200,000 clicks is next to nothing.

Did you get your radiator problem fixed? To be honest when mine was leaking I just had it totally replaced. Replacing the hoses wouldn't be a bad idea either.

I got tired of topping off the rad. EVERY day and that's just for driving within the city....

And if you're going to get that done might as well do the timing belt and water pump while you're at it if you're not sure if that was done recently.

i replaced my radiator, it was cracked at the bottom. but sometimes it leaks coolant from the small hose thats connected to the reservoir tank and other end is connected to radiator next to the radiator cap. i figured a way of stopping that leak while i was at the junkyard the other day i saw many integras had a small clip thing locked the reservoir hose to stop the leak. well so far i am happy with my car and all i am looking for right now is a cold air intake. anyhow iam not sure about the timing belt and i doubt previous owner didn't change it. i'll change it soon as i save up some money. it should cost around $500 right? including water pump.

all integras have high rpms. and 120km at 3000rpm is normal but i dont see how you getting lower mileage ..your calculation does not seem rite



Does integras have 1 or 2 O2 sensors?

^depends on what year

Buddy more often than not I just come on here for comic relief ( and obviously the fact that my daily driver is an Integra, which I happen to think is a great car ) trust me there is very close to 0% valuable information that is posted here.

Stop taking yourself so seriously and trying to be all high and mighty, because your not...

P.S. on Supra or NABR forums you will never ever see a thread anywhere near as ridiculous as this, and if somehow there was, they would get ripped a new one faster than an SP57 spooling up. I'm just trying to do my duty. I am sure most people know I am correct, even if they don't want to admit it, but I don't really have any respect for this forum, so I don't care.

Sorry but thats the truth.

to you there may not be any info of value but to others like newbies to integras or cars in general there is.

since you know you're correct and think you have all the answers maybe you can tell us why you're comparing supras to integras. you can't! you can't compare a supra froum to an integra forum. supras aren't as common as integras and they're not nearly as affordable as them either. you're bound to get more newbies with tegs than you would with supras. it comes with the price tag.

it's your duty? who gave you the job of bashing newbies trying to learn a thing or 2?

i'm not trying to be high and mighty, i'm just sticking up for the little guy that's actually trying to learn something about their car.

mark, why you letting this butt pirate even talk. He can go to supra forums and stay there. Since ive been a member here, hes always been a fag saying stupid ----. I hope hes at the meet, not just another keyboard warrior.

Censorship, always the answer for you eh? And I'm flattered you have been following my career here on integra forums.

You hope I come out to a meet, is that a public threat?

P.S. Buff4Prez, you might be right, we just have vastly different standards at the other sites, and sometimes I forget that the level of expertise ( or lack of it ) is much different.

yo don't u have any better to do than goofing around? seriously you need help. if you dont have any important tip/advice you dont even have to come here and post a reply. chill out man. Nobody is born with skills/knowledge.

Ok, but it sounds like you are the one the needs to chill out. I didn't know the internet is only to be used for important stuff like that...

The clip thing is probably the hose clamp.

Well just be careful of the big rad hose. Mine burst about a week after I replaced the rad....

I think that price is about right for the pump and belt give or take.

why need for threat? your obviously too smart for us. i just think you talk too much smack and need to back it up.

1st off, stop gettin on and off the gas pedal on the highway, keep it steady (cruise control if u have.. ) too see how much mileage u get..

2nd off, What kinda gas you use? 94 sunoco octane costs more BUT burns leaner and does get you MUCH better mileage I FIND..

3rd off, i duno what you're bitchin about dude, in 5th gear i'm doing 110kms/hr and 4000RPM !!! not to mention vtec at 4800 just over 135kms/hour talk about burning gas...

lol 2700-3000RPM at 120km/h thats great im at about 4000RPM at that speed me and my stupid short geared tranny

LOl yeah i hate looking @ the rpms so high cruseing .. let off the gas and the motor slows you down so much. thank god 4 cruise control id have the worst gas milage w/o it

I'm not sure what you mean by burns leaner? As far as I know fuel cannot be burnt either leaner or richer on its own, it is simply mixed with a given quantity of air as determined by the ecu, and that determines the A/F ratio.

Don't concentrate on how many Km's tht car has but rather what condition the motor is in. If you don't know when anything was replaced I would start by checking the T-belt, fluids and just do a basic tune up. I personally dont think breaks are needed to cool the car, keep an eye on the thermostat to make sure it isn't overheating. If your rad, fan, and thermostat are working properly the car should regulate itself ant not overheat.

I had a 92 accord with 420 000K's and drove it to NYC and back a few times without any worries. Never needed to take breaks for the car. I maintained the car well and it ran great. I sold the car to a friend, it now has like 430 on it and still going. I've seen integras with 400K on the original motor and tranny. If properly maintained you'll have years of driving left on that car.

There's a reason that people still buy older hondas :)

Have a B20 90% city about 520 on full tank, rpm sounds about right.Thanks to this forum and tech sec, and everything else, had a DA and DC now, know the diff. between the two after i joined this forum and a lot of other things. Thanks for the inputs.

correct me if i'm wrong, but the 94 octane needs more heat to light up, meaning no premature combustion giving better performance. On the other hand an 89 lights up faster taking up less energy due to iso - octane or w/e it's called.. The way i look at is if you run your motor HOT at higher rpms, you should use higher octane levels.. If you don't beat on the car too much and don't take it to 7000-10000 rpm on the highway, track, etc. you don't really need high octane. By LEAN i don't mean rich/lean so there's no need to pull out your spark plugs and check to see if they're too white or dark/wet.. What i mean is that the burning rate of a 94 octane on the highway is more efficient (at higher rpms/higher temperatures) than an 89 octane is because 89 just burns too fast so it needs to dump in more fuel.. If i'm wrong, please feel free to correct me in an appropriate manner...

Thanks!

Ya your pretty much right about 94 takes loger to burn then 87 and will actually change your igntion timming up a bit. But the high octane doesnt neccessarly have to be used with higher rpm's its more for higher compresion ratios, 87 iso-octane in car car with say 10.0:1 would knock in the motor the higher the compression ratio the higher the octane needed. And i dont think you will use more gas at higer rpms with a lower octane t you may get a few extra kms on the highway lets say because of the slower burn rate but even if you did you just paid an extra 14 cents per liter to do so, so i would say if the engine doesnt need it i wouldnt use it unless you just wanted to run a cleaner gas and it gives you piece of mind to run it in you engine .
