Driving on highway with high RPM = Bad?
Is it bad to drive on the highway (407) with OD off (3rd gear) for like 2 minutes on an automatic tranny. BBARBLO said driving on the highway with high rpms on auto tranny are causes of blown trannys.
Just wondering... because its very hard to engage i-VTEC without turning OD off unless using (1 , 2 ), so the time vtec screams is on the 407 ramp.
Another question...
On Wide Open Throttles, the car makes a deep "VROOOOOOOOOOOOOM" sound (up to 4500RPM because it will shift to 2nd) but on moderate acceleration it doesnt sound like that, and vtec is not engaged during a WOT because you cant hear the "pump like sound"
VTEC = FUN and Destructive.

I really don't know, but I wouldn't be surprised if driving at high rpm's was the cause of blown trannys.
Driving at high rpm's unnecessarily uses more gas since it causes the engine to work harder and sustained usage like that can't be good for your engine/tranny. Maybe it's "ok" if you did it once in a while, but if you did it rather often then you would get to know your mechanic really well and should be able to put his children through university.

It's easier to drive "in the VTEC" with a 5spd.
Driving with the OD off might not be too healthy for the tranny. I don't think stock autos are optimized for hard driving.
In a 5spd you set the pace.
(gotta love the VTEC!)

Man, I didn't say high RPM caused it, I said overheating the auto tranny causes blown trannys. I try to be precise in my wording, so every word counts...
Overheat an auto tranny, and it will die. If you know how auto trannies work you'll understand why....basically, the tranny moves power through fluid...there is no clutch or anything, it's all hydraulic manipulation through the valvebody and torque converter. In order to make trannies last, Honda uses a 3 row instead of 2 row radiator on it's auto cars and has tranny fluid lines running through the rad for cooling purposes. So a few minutes of booting around won't kill it, but if you drive it like you stole it for about 1 hr, you potentially run the risk of damage. Racing auto trannies use synthetic fluids and BIG BIG oil coolers.

i-VTEC hardly engages, even on hard throttles so the time to use it is on a freeway with OD off. i-VTEC engages at 4500 rpm, and thats around 110km on 3rd gear, so at 140 it is around 5800, redline is 6500.
Why goto the track? Why speed 10km over the speed limit which I suppose everyone does and if you want to prove me wrong than we'll

AzimuthX,
I was just being curious... when entering the highway all you need to do is match the speed of the cars your going to be merging with (easy part) and find a gap (sometimes harder to do)
150 is just a way to get cops to notice... take it from me took 2 tickets to slow my *** down ... now hardly ever break the limit... yes most of the time I'm in the right hand lane as people pass me but hey cops down notice me then, which is better for me... if I want to hit 150 or 190 or whatever I'll hit the track.
just my 2 cents...

AzimuthX, heed gatherer's advice. Primarilly, I say this because you are not an experienced driver. While 150 km/h isn't really fast, it's fast enough for you to lose your life. This is coming from someone who's driven 240 km/h and has gone over 200 km/h many times for extended periods of time. I really think it's a stupid thing to do now...The car gets extrememly light in the steering, and prolly the smallest thing would have killed me in an instant. In my old car I used to pass ppl on the shoulder in rushour traffic doing 180+ 
and I can't even tell you how many blessings I've counted. I used to drift my way to work at 8AM on highway offramps. (wakeup-call for sure, but definitely not smart) 150 km/h is enough to send an SUV flipping end over end to a halt... If you know what's good for you, you won't do it; just think of your parents and how hard they worked to get that CRV, and how they'd blame themselves if you crashed.
There is no need to turn OD off....that's for towing, not performance. Performance can be extracted from the auto tranny computer by keeping the thottle at WOT...pedal to the metal! As soon as you back off, it will shift to the next gear, so as long as you wanna keep going, pedal to the metal. That's what sucks about auto trannies....it's either all go or no go. Either WOT, or puttin' around like an old man.

1. I don't promote speed but sure.. speeding can be fun! I don't have Vtec... but that's fine with me... I just keep it in gear 4 when I'm on the highway and it sits nice and high.. but why would you do that? With gas prices @ 80 cents a liter for the cheap **** and 95 cents a liter for the 94 stuff....... it's not worth it.. your rice burners become fuel guzzlers.
2. SUVs are not drag racing cars...... I do not suggest you attempt to drag race in it... Unless of course you're looking for a bit of fun. I use to drive a Lexus RX300 and I would drag race with it against any car I saw "dressed up to the ****" on Eglinton close to my house. And yes.. my 2 ton SUV can keep up with Integras done right to the ****. So blah.... That was when I was young and stupid. I ended up bumping it off a curb so that ended my stupid childish nieve days.
Also.. If I don't remember wrong.. SUVs are banned from the Shannonville Track..... except for 1 SUV.. the BMW X5. Apparently that's the only SUV stable enough to handle the track.
A 3.0 X5 doesn't race that well but I can imagine a 4.6i would
3. I have never gotten a speeding ticket so I count my lucky stars too...... but I do have a careless driving charge under my belt.. so I don't do stupid **** anymore like drive fast... I drive the speed of traffic... Unless it's 4 AM and I'm the only one on the highway. If that's the case..... if I **** up.. it'll be me that ***** up and not other people.
Speed Kills. Hey.. isn't there a Bush song called Speed Kills? There u go.. proof that you'll get iced if you speed and be stupid.

why don't you buy your own car to experiment with, rather than engaging vtec on an AUTO SUV that your father worked hard for. Also... are you the one doing this?, or is your dad a bad influence on you? btw... honda warranty doesn't cover abuse

There's an idea, a beater would do you good.... some great beaters include Toyta Tercel, Hyundai Accent, Ford Escort GT, Nissan 2000NX, Saturn SL2/SC2 5 spd....all light enough to have fun, powerful enough to dick around, but not powerful enough to get too out of control, and all can be had real cheap, like under $3000.

I respect all of your opinions 
SUV were definately not made for drag racing and so weren't Civics
A CR-V will definately win a Civic Sedan / HB Stock According to Numerous Track Results.
Don't worry, I will have my own car to dick around if I do get placement in Toshiba as Computer Engineer.
NOSpleeny, you and your gas prices...

Hrm... I have my doubts... according to Honda's site... the CR-V can achieve 0-100 in 10.5 seconds while a Civic LX (NON-VTEC) can reach there in 10.3 seconds.
Although the Civic LX (4 door) is a bit low on the torque and HP.. it's a lot lighter... and it's drag is boat loads less. Think of the size of the sails on the side of the CR-V. I'll be surprised if you boot that car and it doesn't take flight
But I say it'll be a close race between a stock 2002 Civic LX and a CR-V (2002).
However.. an SiR would consume the CR-V like it was dinner.

come on a almost stock cx hatchback (I've decided not to go through the effort of replacing my intake which is the only power mod on the car) against the stock CRV... I'll even throw in my lack of experince driving down the 1/4 mile (never done it beforehow hard can it be?)
