Turbos also rob you of power, by adding a restriction in the exhaust. There is no such thing as a free lunch, they're both pretty close in power drain.
I find that very hard to believe, the powerloss of the restriction you create in the exhaust is nothing compared to the powerloss of driving it direct.

Something that being pondered amongst some friends who are into the amateur rally scene is to build a kind of KERS / regenerative braking system. Except rather than store the energy in batteries you store compressed air into a dive cylinder. When you want a boost you can then dump that air through the intake.
This has been done in WRC, were the excess presure of the turbo coming from the dumpvalve were stored in tanks in the bumpers, to be used under acceleration. It worked, then got banned by the FIA.

The good thing about a turbo is that it is free power your using were the supercharger robs you of power to turn the wheels. Also, on a diesel, you can cram as much air in as you like, the more the better. On a petrol though, feeding more air means also injecting more fuel, or it will run lean and not run properly. Also on a diesel, low down you already have loads of torque, so you only need it more at the top end.
So all this makes the supercharger more suited to petrol.
The ebay thing is interesting, but I wouldnt do it that way. The path from the supercharger is so long that you still have a lag to cope with. Also, at higher revs, I reckon you are starving the turbo of air, as the charger only displaces air and that wont be enough for the turbo. The problem is that they are in series, if they were parallel, it would be better.
The merc (clk or slk I think) had them parallel, with the supercharger on an elektro magnetic clutch. It then only works on low rpm, untill the turbo kicks in. If you were to set it up like this on a tdi, that might work well.

#1 cause is driving like a taxi-man: expecting the engine to 'lug' hard at low RPM
But that is exactly what offroaders doing all the time. I also do this driving my roadcar to get good fuel consumption; fewer revs means less fuel. So if that kills a DMF, it is not the thing to have these days, even more so on an off road vehicle.

Oi mike, you cant spell! That, and you just telling us you use it for the sump as well, so judging from that, you are as carp as I am.
I do use a gasket between block and front cover, but not between block and sump, like yourself.
I dont use it on the p gasket, there is a seration in there which allows a bit of movement and this seals ok as it is.
Keep smiling, Daan

I must admit to not having much succes with gaskets, and revert to dow corning black gue. Landrover recommends this for the sump I think, I saw a workshop bulletin once were it stated to use it to stop leaks. The sump is never flat enough for a gasket to take up, and than you have the point were the block meets the front cover which is never completely smooth. They are also cast iron and aluminium, so different expansion. A gasket is not good enough here in my opinion.
also, the great thing with instant when you go offroading in the middle of nowhere is you only need one tube and you can seal the whole car!
Disadvantage is if you use too much, it will end up in the oil and the mess you have to clear up if you take it apart again.

one problem is that the q plate registration is actually younger than mine, which is from 2008. Assuming they are in a numerical order, which I think they are. hmm...

I think that looks realy smart, even if orange is not my taste. I think it is a cat b write off with the chassis bend, and rebuild on a new chassis. The fact that it is on a q-plate makes it more reliable in my eyes. It means he had someone looking at it, and more importantly, he has had to show evidence that the parts were not stolen. The vosa and dvla are very touchy on this with landrovers, because they are stolen so much these days.
I think go and have a look if this is the car you want.

Well, If you cut the chassis, you will need the test. Many people are worried about this, but it is not hard. Rather than trying to avoid it, which almost everyone does, I am all for facing the test head on and have peace of mind in years to come that your car is 100% legal.

This shows the problem with any of the lower grade steels, like cds and blueband : it is al very well mentioning strength, but the moment you touch it with a welder, this all goes to pop quite alarmingly, like you see on the picture.
Daan

Isnt the real arguement not between pipe and tube, I believe the main problem is that 12swg cds is too thin, you wouldnt make a chassis that thin would you?jumping to 10swg gives you 3.24
I am going to reply to this thread by stating facts: A landrover chassis is made out of 14 swg (2mm thick).
Another fact: you can get cds in 10 swg as well.

Ok adrian, looks good. i noticed you are smoking holes into just about anything which is good. How much does this winch actually weigh?
Also, you little man has the same tricycle as little adrian, how does he get on with it?

That seem a bit like hard work to me.
I have one similar to this one:
you just put them on when its freezing, plug it in when you drive off, have a hot behind 5 min later. Its brilliant for my truck that has no heater, especially last year when I used it at min 10. I also use a plug in electric air blower to blow on the front screen to stop it freezing up. a £10 ebay job is just fine. My series truck is brilliant in the winter like this.

One thing about the 300Tdi that everybody knows is the very qyick ability to loosw water. Having a very accurate water temperature gauge with a coolant loss sensor should make you more aware of any coolant probles......
The thing is HOT.
In one country HOT = Deg C.
In otheres hot = 30Deg C....
I don't talk hot...Just in ambient temperatures......
When I bougt my temperature gauge a lap top was £600......
I have read that the main problem with a 300 is that the sensor sits about 4" lower than the highest point in the cooling system. That is a problem I would look at first myself, rather than spend good dosh on something to replace something that actually works quite well.
As fridge says in the red is no good, the rest is just background info, causing you to have your attention somewhere else than on the road.

i dont suspect your get an answer on that sva question, but tray backing doesnt alter chassis does it
otherwise 90% of the challenge trucks wouldnt be able to compete in competitions requiring a road legal truck. SVA/IVA is a big familiy size can of worms thats best left unopened under the competition forum :-) just my view on it anywaymarkyb, you're quite correct, most competition trucks are trailered so dont have to be road legal ( in the official sence). But the organiser usually requires MOT when they mention road legal, and that is enough. You are also correct that the SVA is not a subject for the competition forum.

Looks like a fair scoring system to me, will be interesting to see how it works out.

I used these:
http://www.ndeclarketransmissions.co.uk/page1.htm
From memory, it is the SAE1140 type joint, Which I think is what superwinch uses as well. but as you found getting one made is not cheap.
Alternatively, this uj is also used on the freelander propshaft and the MGB propshaft (My prop is made up with these)
I used a 1140 joke at the PTO end, MGB UJ, Freelander fixed prop, MGB sliding prop, MGB UJ, 1140 joke at winch end. All these jokes share the same UJ, so 1 spare cross piece will do you on the trail.
This also means that you could get an MGB prop or freelander prop and graft that on your shafts. But I would have look on the bay first before you go that route, or send a PM to adrian....

EBAY.
Bought many over the years; people keep borrowing them at work and dont return them.

I dont normally mess with this for too long; in the end if the gear pattern looks right and the whole thing runs freely for a full crownwheel rotation, I usually call it good.
It is probably better to put this in tools and fabrication, so the diff grown ups read it too.

If the car is unused why not remove the wheels, store them in the garage and leave the car on axle stands? This will make theft of either the car or the wheels difficult. RangeRovers are not nearly such a popular theft target as Defenders so I should not worry too much.
But if you do that, the potential thief goes 'someone else had the wheels, I have the winch' type thing. The problem with wheel locks is that one day you have a flat and you find the key is missing. Still they are the solution to your problem.

Good effort to set this up.

you have to remove the front cover the first time round. Then you can drill out the rivets, tap the holes and bolt it back on, making it easyer the next time.

But on a petrol engine this effect is more of a problem than on a diesel, due to changes in combustion due to backpressure. Also, there is another effect with a turbo: the outlet stroke may be harder due to backpressure, but the intake stroke is easier, because there is no longer a vacuum, but a pressure. So this test would not take that into account.
But as said, on a diesel it is very lucrative, so much so that I am not aware of n/a diesels available anymore, but most petrol engines still are n/a.
