2.5na driving style (revs)

CharlesY said:

Yes, but there's always someone (who has had a few crashes in all likelihood) who comes out with "Never had a accident but probably caused hundreds" statement.

I treated that as it deserved - with contempt.

In her youth in Sweden my mother was a skiing champion. No doubt some modern ski-expert will say my mother probably caused hundreds of innocent skiers to fall on their arses.

Same thing.

The skiing champion point is irrelevant, a skiing champion doesn't cause accidents, but a slow, incompetent novice skiier who shouldn't be allowed on the black run can quite easily cause an accident. You said yourself she was incapable of changing gear and destroyed several gearboxes, yet you defend her driving?

The mind boggles. :der:

I think the consensus is you can drive your diesel however the **** you like as long as you change gears when you're meant to

On another note. I remember reading in a thread somewhere that in first gear, you go 5 miles an hour for each 1,000 rpm, so I could gauge that I was doing 4,000 RPM by doing 20MPH, 4,000 being the highest that the engine's supposed to go. Is actually doing 4,000 (and/or 20mph in 1st) likely to damage me rockers or shall I give it a go? I just want to hear the kind of roar that I never want to go beyond in any gear Given that CharlesY has said that 2nd is twice as high a ratio, I guess that I could do 40 in 2nd to be doing 4,000? I've never heard it roar more than about 25 mph in 2nd gear trying to get up and stay in 3rd on a hill, so I guess I'm well within limits

That's not a good gauge of speed as there's a many number of variables that will affect your speed to rev ratio, gearing and tyres being just two of them. the NA engine is not designed to rev high, it produces the most torque low down in the rev range and was created to be a reliable maintenance free (ish) work horse, not a high revving screamer of an engine. Chances are the engine will just run out of puff above 4000 RPM so your revs will not increase, but take it any higher and you risk damaging the engine or at least reducing it's workable life.

If you want to hear an engine rev a bit higher, buy a motorbike or a japanese sports car. I can rev my bike to 16,000 rpm all day long but I wouldn't take my land rover to a quarter of that.

I think that the claim is wrong anyway. Looking at my lt77 gearbox ratios, I have the following:

1st: 3.5850:1
2nd: 2.3008:1
3rd: 1.5074:1
4th: 1:1
5th: 0.8314:1

so if 20mph in 1st is 4,000 revs, then in 2nd, I would be doing ~31 mph at 4,000 revs, ~47 in 3rd, ~71 in 4th or ~86 in 5th

Seems about right, but it's purely based on the idea that 20mph in 1st is 4,000 revs

NEVER pull away from a standing start in second gear.

ALWAYS start her moving in FIRST GEAR.

Second year is TWICE as high a gear as first gear, and so you WILL be wearing out the clutch up to FOUR TIMES as much every time you start off.

That's the way it is.

Unless it's down hill of course, then just let it roll a bit and away you go in second and then straight into third asap.
I agree with starting in first as a landy is a lot of weight to get moving but once moving keep the revs low. In a higher gear you go further at each firing stroke so saving fuel.

In ROUND NUMBERS, as a general principle,

in a 4 speed gearbox in a car sort of vehicle,
you will do ABOUT 5mph per 1,000 rpm in 1st, 10 in 2nd, 15 in 3rd, and 20 in top - more or less.

In a typical 5 speed box think 5, 10, 15, 20 and 25, per 1000 revs in 1st, 2nd, 3rd, 4th, and 5th more or less.

What I am trying to point out is that 2nd gear is just about TWICE higher than 1st in most car/van sort of vehicles, and so using 2nd gear to start of will soon wear the clutch out. In HGVs (I have a Class 1 HGV licence Mr Ghost) things are very different, and you might have 15 gears to play with, which is fun.

And as for this stuff .... "The skiing champion point is irrelevant, a skiing champion doesn't cause accidents, but a slow, incompetent novice skiier who shouldn't be allowed on the black run can quite easily cause an accident. You said yourself she was incapable of changing gear and destroyed several gearboxes, yet you defend her driving" .... yes indeed I do.

Having passed her test in 1958 at the first attempt, Mum learned the art of driving quite well, and by the time a few years had passed she really was pretty good. I never said she was incapable of changing gear! I said she would go to the shops and back in one gear. But later she worked out that there was a better way. In her prime she did have a tendency to go a little too swiftly for my liking. But for sure, she held no-one back, caused no upsets, and never once got a point or even a parking ticket, and I can say hand on heart, I don't believe she ever caused an accident either.

I wonder what Ghost can say about HIS driving record? I can say mine is pretty good, but I've had a few points over the years, and some bumps, but none my fault. I try very hard to drive carefully, but sometimes the nutters and experts make it difficult.

My mother was always able to shrug off experts and nutters. She never wasted time on them. Let them go ahead. It is much easier to keep well away from nutters and experts who are ahead of you, that when they are far too close behind you. I try to follow her example.

Talking of mothers' driving skills, mine is 99 years old in May, never taken a driving test, she didn't have to way back then, never had an accident and still drives to the shops every week. About a ten mile round trip. I sometimes travel as passenger and have no worries about her style of driving, which is more than I can say about a lot of younger drivers.

You're fighting a losing battle here I'm afraid, there's no point in attempting to defend the undefendable. The plain old truth is that if someone is not confident enough to perform basic car control procedures such as changing gear, they should either be driving an automatic or not at all. I wouldn't follow her example too closely if I were you, sailing blindly through each journey with no heed for other road users and 'shrugging off' those who you disconvenience is not a trait of a good driver. And don't try to tell me completing entire journeys in nothing higher than first gear is acceptable if you live anywhere other than central London.

Resorting to questioning my own driving record is a childish and feeble attempt at retalliation from a man who knows he is in the wrong. How good or bad a driver I am is irrelevant, I could start reeling off a list of cars, motorbikes and vans that I've driven, miles I've covered, tests I've passed and accidents witnessed or been involved in, but to do so would be bringing myself down to your immature level which I'm not prepared to do.

I'm sure if we all drove everywhere at 25 mph in first there would be a lot less accidents, that doesn't prove your mum is a safe driver, quite the opposite. If it were anyone other than your mother being discussed you would see the same point of view.
