Default When exactly is it considered "Luggin Your Engine?"

I been doin some frequent long distance trips and tryin my best to keep the rpm low as possible for gas mileage.... Im just guessin but to me it seems like anything below 2200 rpm while cruisin is bad, correct me...

I don't know for a fact, but I would not assume so. I notice my parents' cars which have automatic trans normally cruise with the RPM below 2,000. I've tried cruising around in the city in 5th, like 20-30mph... with very little load, and I'm still above 2K...

Is this w/ your gsr? Aren't the rpm's high anyway for cruising? I can't keep mine low cuz I have a short geared tranny, but if you think in the sense of an automatic tranny then when you are just cruising (like cruise control) you shift to your highest gear. Whenever you attempt to accelerate or increase your speed, you need to downshift. This way although you are at a very low rpm, it's not like your engine is working hard to accelerate the car, just to simply keep it moving. In the same respect, you downshift to accelerate to prevent putting a load on the engine at such a low rpm, where our Honda's have virtually no power. Does that make sense? Hopefully someone will correct me if I'm wrong... it's just what I think.

That's pretty much it. Lugging the engine is putting load on the car at such low RPM that the engine will actually make a "chugging" sound or make a flatulent sound (if you have exhaust). It just SOUNDS like the engine doesn't have enough power to move the car. If that happens, just switch gears and accelerate smoothly. I cruise (read: no load-light throttle) at about 1,800RPM at 40MPH (5th). I accelerate at 40 at about 2,500+RPM to avoid lugging the engine. Get it?

Plus if you don't, it's that much harder to accelerate. The engine doesn't make enough power at low rpm's to try to move the car, so when you step on it, it takes a long time to get to your desired speed. If you just downshift one gear, you'll be fine. You don't have to though... but it's a good idea.

OT: haha I miss having an LS tranny (assuming you have one w/ those numbers). Now I have b20+b16 tranny so I cruise at 4000@75mph in 5th.

makes sense to me, and that exactly what I try to lately. Like if the road is flat level or slightly down hill, once I get going... I'll dump it into 5th gear and give it just a tiny bit of throttle to maintain speed. But I was saying, even at moderate speed levels, I'm still above 2K rpms. But this does get me a bit more gas mileage, and I'm confident its not harming the motor. You just have to down shift more often when needed, or control your driving habits

That's where I have trouble! I try to go w/out redlining it every day, I really do...

Now here's what I'm wondering, as far as gas mileage goes, especially because I have a short-geared tranny. I've only heard that the motor is actually more efficient at higher rpm's (like 3000-5000) rather than down low, so wouldn't you get better gas mileage if you shifted at around 5000rpm, yet kept your foot easy on the pedal? This way, you're not consuming large amounts of fuel by flooring it, yet your still using the efficiency of the motor at higher rpm's. Anyone got any info in this direction? I just noticed that although I cruise at 4000rpm I still got over 200 miles a tank. I'll know my exact mpg by the end of today, but it seems like I'm doing decent.

im making over 300... perhaps you should lower your rpms. i shift at like 2.5-3 when its cold and then higher when its warm but never in vtec.

i let myself have fun 1 out of 3 tanks though so i dont get bored or start driving like an old man.

i don't drive like an old man. i have a cammed LS, so i have VTEC all the time pretty much. anyways, here's what i know, from stock to cams, it hasn't changed:
1) shifting at 3500 gets better mileage than at 3000. this is because with more power, you can accelerate faster, which means less time spent on the gas pedal. this more than makes up for the extra fuel from revving higher. more mileage.
2) i always use about 50%-60% throttle to accelerate in normal traffic. same reason as #1.
3) i can climb many hills below 2000rpm. i think that's a non-VTEC phenomenon, but i can and i do. i also stay in a gear if i only need light acceleration unless the engine speed drops below about 1700rpm. light acceleration at that speed is still good, even with Crower 62404's (stage 3).

im still trying diff throttles but ill see how the 3500 goes instead of 3k next time i fill up. very little left so i could drive in vtec and get to the store once or something.

are you sure climbing hills that low is good? cause ive got this ridiculously tall and steep (to a honda ) hill that i have to drive up sometimes and i think its more than a quarter mile. ill check the odometer next time but if i drive it in 4th the rpms start gettin kinda high. if i drive it in 5th i will start losing speed. ******* hill...

i meant i drive up some fairly impressive hills in 5th gear (LS 5th gear!) at 1800-2000rpm and don't lose any speed. i drove my mom's 3.5L chrysler automatic and it downshifts to 3rd (it's a 4-speed auto) trying to do the same vehicle speed up that hill, which is about 40-45mph. it can't make it in top gear even with twice the displacement, haha. POS chrysler.

why would it hurt the engine? engines make power, that's what they do.

don't you mean DOH!-mestics?

oh yeah, forgot to mention. that car has 220hp (factory claim) and spins 1 giant chrome 17" with nice 225-55R17's on it very easily in first, even on hot pavement.

wouldnt that be the torque that we are lacking? my friend had an old mercury grand marquis, the thing made ******* ridiculous torque, but only at like * &lt; 1k rpm...

i bet so. with minor mods LSs make 130ft-lb of wheel torque, but GSRs seem to need a lot of mods or really good tuning to hit that. and they make their torque a LOT higher, too. known fact. LS intake ports don't flow as well and therefore make peak torque lower. exhaust ports are nice, though. i'll be porting my intake ports later this year, and we'll see if i lose a bunch of low-end power. i expect to, but with LS i have a crapload of torque to lose. i'll gladly trade it for torque higher up, where it makes more hp.

as for the original topic, i lugging isn't bad for the engine, just bad for fuel economy. i do it just to prove to myself that i can do it. BTW, i don't really care about gas mileage. i'm going to have fun with my car, dammit, and nobody walking around in the desert with a nuke on a frickin camel is going to stop me.

Same here, I just filled up today for 24.00 (9.3 gallons) and found out I made 24mpg. That's w/ redlining it at least once a day and driving about 40 miles a day. Not too bad, considering at least an hour of that is on the freeway at 4000rpm in 5th gear (75mph-80mph). I love my short geared tranny!

My b20b has low horsepower and high torque, 120hp/140tq, so I can't wait to start modding it.
