so do the swap then
I have probably said this 10 times here, I will maybe do it or maybe not, and I am currently gathering as much actual information as I can from people with real world knowledge.

One of those people was on this forum after a few pages, and the rest are on another forum.

There may be new people who have relevant information who did not post that information yet, as happened on the other forum where someone posted after one week.

If someone has a really good reason why it will not work then I won't do it.

So far no one has given me that reason.

The only reason I continue to post here is because it is hilariously funny watching people lose their minds, because their latest pathetic gotcha question failed, and they have to come back and try one more time to catch me out and beat me.

And even though they are always wrong, they just keep coming back.

I do not post new comments here, I only respond to people who comment here, with their crazy ideas or insults.

If those people could just move on then this thread would end.

Unless of course someone reads it and has actual real world knowledge and shares that here, which is possible.
 
I never said you would be driving at 500rpm. I took you initially posted numbers as if you had done some calculations.
Or the need for acceleration.


And anybody that does pose a serious engineering question is Pooh poohed anyway what’s the diff?

J
But all of the problems that you talk about would only occur if I was driving at 500 RPM, so that number is relevant.

I have not seen any serious engineering comments only hysterical garbage about situations that have no relationship to my real world scenario which I explained clearly.

That is why you guys are hilariously funny.

see i just went ahead and did it, and there were plenty saying it couldnt be done and noone saying how to do it

Exactly, but I don't need to do it, it was just an idea that I had.

I decided to get some input from the Range Rover people on a Range Rover forum, in case there was an idea I missed.

The torque converter not locking up was one thing that I did not think of.

But I will be able to see that with my OBD reader on my first test drive of the set up.

Also given how far inside of the standard operating parameters for my engine and gearbox that I will be, I expect the torque converter to lock up.

It is months before I would need to do the modification, if I was going to do it.

I already spent a month researching this idea before I asked the question here.

As you know most people are armchair critics who have no idea about the real world and I thought I would just ignore them here, but I found them to be hilariously funny.

The humor now is not about what they say (because they are just repeating themselves) but rather it is the fact that they are so desperate to be right that even after 25 pages of being wrong, and after hundreds of loser comments, they are still coming back trying again one more time to catch me out.

One of them even attacked me for typing the word "not" instead of the word "no" because that is all that he could find on me, and that was just a voice dictation error.

I have no desire to prove anyone wrong here by doing it then stating that it worked out great, because none of them here would believe me anyway.

Such is the strength of their internal desire to always be right in their own mind, despite being wrong.

I just have a desire to have an uneventful and enjoyable trip to Portugal and back, visiting some friends along the way, with my dogs in my 2002 L322.

If that means doing a simple differential modification then I will do it, and if it means doing nothing then I will do that.
 
No. Never did I mention what rpm you would be doing at that speed.



Ok so my comments have been hysterical on this thread?

J
You keep making comments about problems that I would have, that would only exist if I was driving along at about 500 RPM.

Therefore while you have not specifically said a particular RPM that I would be driving at, you have continued to imply in a hysterical way that I would suffer problems that would only exist at around 500 RPM.

This is why I am not gratefully thanking all of you geniuses for your wonderful input, and why I have instead explained many times that you guys are living in a fantasy world of hysteria, while I am in the real world.

If you think I am so stupid to think a car that idles at 750+/- RPM. Could be driven at 500rpm, Then you are not as technically proficient as you say you are to even mention it as possible.

J
 
The attached image is from RRPhil on another forum where he has been helping me to understand the actual situation not the hysterical made up irrelevant situation.

According to his calculations without the modification at 75 mph I will be doing 75/39.8x1,000 RPM = 2,542 RPM.

According to his calculations without the modification at 75 mph I will be doing 75/29.5x1,000 RPM = 1,884 RPM.

Do the people here think my engine will struggle at 1,884 RPM and start lugging and will not lock up the torque converter at 75mph and be totally out of its usable torque range?

Do they think that my gearbox will decide to stay in fourth gear at this RPM level?

Do they think that I will need to shift down a gear or mash my foot to the floor if there is a slight incline or a headwind at 1,884 RPM?

At that RPM my engine produces about 350 Nm of torque so it will not be struggling given that my car will be at its lowest weight.

My car is designed to tow up to 140% of its weight, meaning it can happily move 240% of the total weight that I will be moving.

I have explained all of this before but hopefully this will be the last time that I will have to explain it, although it might be a little bit technical for some of the people here.
Those are different rev ranges to your earlier statements

You are speaking about a man who is so technically proficient that he thought changing the diffs would affect the speedo. :rolleyes:

And I think I said a different mile per hour.

I hadn't done the exact calculation and I was only estimating, giving you an example.

It doesn't matter if I was giving an estimate, or if I had made an exact calculation, because it doesn't change the overall idea whatsoever.

It would only matter if the situation was me driving at around 500 RPM on the highway, which would be impossible with a 24% difference in the differential ratios.

Anyone can do that calculation in their head in five seconds.

If it is normally at 2,000 RPM in 5th gear on the highway then the change of differentials would result in around a 24% reduction in RPM which is 2,000 x 0.76 = 1,520 RPM.

That is not 500 RPM.

If it is normally at 1,500 RPM in 5th gear on the highway then the change of differentials would result in around a 24% reduction in RPM which is 1,500 x 0.76 = 1,140 RPM.

That is also not 500 RPM.

Once again you are making an irrelevant point and trying a gotcha question rather than just accepting that you are being hysterical about things that are irrelevant to my situation.

For maybe the 20th time now, if I was driving with a full horse float to Portugal and I was concerned about my acceleration then your comments would be valid, but I have made it clear maybe 20 times that I am not going to be driving in those circumstances.

This is why I don't understand why you keep coming back here saying exactly the same things expecting me to give you some kind of respect that you do not deserve.

Your examples are hysterical based on a situation that does not apply to me.

How many more times do you need me to say the same thing before you will listen?

We have about 25 pages of me repeating myself and you idiots refusing to accept the actual situation, then repeating yourselves thinking that you are helping me, and thinking that I am too stupid to understand.
 
You are speaking about a man who is so technically proficient that he thought changing the diffs would affect the speedo. :rolleyes:
Most cars run the speedo off the gearbox so that is why I assumed that with the L322.

In that case changing the differential ratio does affect the speedo.

Maybe you didn't know that, but you can look at the attached image for that fact.

But the reason that I asked the initial question was to learn such things.

I did learn that the L322 runs the speedo from the ABS system, from RRPhil on another forum and I thanked him for that important information.

But if you read my initial comment I pointed out that if the speedometer was affected then it would not bother.

I did that to avoid hysterical people bringing up that irrelevant issue.

Got any more empty insults that prove that you don't know anything about cars, because you don't know that most cars actually run their speedo off the gearbox, not the ABS?

And you do not know that in most cars changing the differential ratio will change the speedo accuracy.

Do you understand that every time you try to make me look stupid you only make yourself look stupid?

That is why I keep coming back here.

What is your win / loss ratio, for all of you guys attacking me here, 0/60?

Congratulations for losing again.

So 26 pages so far. This has probably already been answered, but..

Why? I’m genuinely curious now. The time, effort and cost to purely save a few £££ and run your car at 1100rpm vs 1300rpm barely seems worth it.

If this is purely a cost saving measure, have you measured est mpg at 1100rpm vs 1300rpm at XXmph to see roughly what it would it would equate to?

LR when designing the car would have specced that diff ration for a plethora of reasons - peak torque output at XXmph in X gear to offer the best drivability, not putting undue stress on the engine and giving the best fuel economy possible.

Ultimately this might be the sort of job you need to take the plunge and do to help educate anyone who follows your footsteps.

Also if you want to wear Lycra 🤷‍♂️

I have answered this about 100 times now.

Ok not 100 times but it feels like that.

Go back to my original question and you'll see that I have no interest in fuel saving.

I very clearly explained my reasons in my initial question and multiple times since.

But the Einstein's here seem to have no interest in my situation, only their own.

I have also explained that I have no interest in taking the plunge just to educate people here.

In fact I have said several times that if I do it then I will never tell anyone here the outcome.

Firstly because you guys are losers and you don't deserve the information, and secondly because none of you will believe me if it goes great because that will prove you all wrong.

But thank you for proving my point, that Range Rover will have chosen the differential ratio for a wide range of scenarios and I am using it in a narrow scenario and therefore the original differential ratio of the car is not relevant to my situation.

In your OP you say it’s to have a lower RPM when driving at highway speeds. Is this the sole reason then?

Would dropping down to say, 56mph not be a better option for you? It would be unlikely to add any considerable time to your journey - especially if you encountered any traffic etc.
