What speed do you use 5th gear ?

[cowie165]

I love seeing other poeple jumpin left and right all over the place, punchung it off and on again.

Then i cruise along at about 40 and pass em just cause i know which lane will be better.

Hehe

Our family car used to be a 47kW auto corolla. Lane choice was all i had... but as you said, it works!

bunch of grandmas!

except for wreckedhead of course who has to rev to 9722 so he can pull 5th

actually its 9480, anything over just isnt safe.

[Morgs]

I drive everywhere in 1st gear because im scared changing gears will smash the box

[siksII]

above 80-90km/h for me..

[Cubes]

I too cruise around at 50km/h in 5th. Put the foot down a little boost comes up quick and accelerates away easily.

Since the new motor I also find my self pulling out of corners/round abouts in third and fourth from as low as 1000rpm.

I've always dropped it in fifth when cruising at a steady speed.

If I need to accelerate, drop it back a cog.

Maybe this is why I used to get 470km's to a tank of juice (50l) with the rb30det and recently managed 520km's from the rb30det?

I only use 5th over 80km/h. Usually shift at about 3000-3500 when cold, and 4000RPM when warm.

lucky you i get about 200ks to 50l

170km/hr or so when you run out of 4th

in the old r33 manual i don't think i ever really used it too much, except when on the freeways at 100km/hr (even then thats the top of 3rd if you are really hammering it).. but that was melbourne/crapville. I used to see 5th as the "sleep gear" - leave it and you tended to nod off .. :headspin:

[Shell]

i can't believe so many of you drive in 5th at only 50 or 60kmh!! It just feels wrong!

i usually change at about 3000rpm and only use 5th when I get to 90-100kmh!

if i had to sit in an 80 zone for a while i'd probably whack it in 5th, but if that dropped to a 70 zone I'd have it back in 4th...

[R33S2]

Have a look at dyno read outs it shows the torque curve starting about 2200 on mine anything below that is hurting you motor. Read execive wear as oil is not up to it and if you listen you'll hear your motor groaning and its saying put me lower gear please.

[Cubes]

If you are cruising you have very very minimal load on the motor.

With minimal load it doesn't hurt the motor to cruise around at low rev's.

My peak torque is at 2000rpm. 100rwkw which is around 150kw at the flywheel, using the formula Power = Torque x RPM / 5252 that would equate to some where around 740nM of torque.

Sounds almost unrealistic.

[Viscount]

I basically always drive between 2 - 3k revs. I use 5th generally for 80km/h and over.

[Greg]

I don't get it, I always cruise around in 5th so long as the car feels like it has enough "go".. ie down hills or higher speeds.

Why is it bad under 1000rpm?

are you serious? under 1000rpm the engine is either about to stall or blow, putting that sort of strain on the engine is just lazy - change up a gear.

[Cool Hand Luke]

Its actually something you can pick by ear. if the car is loading up it vibrates and sounds like shit bascailly. I found my rb20 if ther are no hills, and im not going to accelerate at all 70km/h was ok, but realistically 80km/h without putting excess load on the car

Ok after reading a lot of posts of why driving at lower revs in x gear is bad... anybody want to mechanically explain why its bad. It's all good to say something but without anything to back it up it means sh#t to me. I can see this thread as the type of thread which attracts lots of comments from kids who don’t really know what they’re talking about so that’s why I ask somebody to mechanically explain it so I can take the explanation literally & put those actions into place if I feel I need to.

Cheers,

i second that

Have u even ridden a mountain/racer bike up a hill very slowly in the highest gear or gone from stationary in the highest gear??? If you have u will know it takes alot more effort/force/energy to do so than if u had it in a lower gear.

Same goes for an engine being loaded at a slow revolution in 5th gear where it is getting an unnecessary load applied to it

[lanc3]

Wouldn't it be common sense to know that forcing movement at a low force wouldn't do much.

And especially with an engine...?

Ok so how is this 'load' physically hurting the engine... name parts exactly...

Trying to ride a mountain bike up a hill in a higher gear doesn’t actually physically damage me, I'm simply not able to do the same thing 'pedal legs' as fast as if in a lower gear, no damage, just reduced speed / power / torque.

So now we come back to an engine, how is an engine different at lower speed as it is at higher RPMs. *pistons, crankshaft, cams, all move the same still, just different speed depending on RPMs*. Each piston ignites creating x amount of torque at the given RPM. Now once the RPM is low enough & cannot create enough torque to move the car in the higher gear how is this actually damaging the engine. Isn’t the engine really just doing the same thing as it is at idle RPM, the internals are still all moving the same BUT the only difference at that same low RPM a lot more Air & Fuel is being injected to try & get the car to accelerate at that low RPM.

This is my understanding of an engine & trying to get some explanation why low RPM in high gear is actually physically damaging / harmful to your engine, I heard someone say something about Oil before? Is oil the final factor? But at the moment with my limited understanding of engines I cannot see why an open full throttle at low RPMs is bad. Please correct / enlighten me.

dude why the hell would u even change at 2500 rpm's thats just silly

skylines can handel 5000 or 5500 quite ok

are yous all stingy with your petrol or did your pops teach yous all to drive
