  1. This what he is talking about.

    You pretty much need a class 4 receiver and then you could mail order the hitch parts. Probably tough to get a receiver hitch in the UK as they use those silly plow shaped things on the back.

    You could probably mail order a receiver from the States, but as stated, it probably is not legal in the UK.

  2. i dont suppose you have the old and new low ratios to hand do you to make a comparison or mph/1000rpms for H and L?

    OK, 3rd line is low range. You can figure out your own speed/1000 rpm

    2007 Defender

    Gear Ratio High Range Overall Ratio

    1st 5.443 23.334 63.0

    2nd 2.839 12.171 32.9

    3rd 1.721 7.378 19.9

    4th 1.223 5.243 14.2

    5th 1.000 4.287 11.6

    6th 0.742 3.181 8.6

    300TDI/TD5 Defenders

    Gear Ratio High Range Overall Ratio

    1st 3.692 18.4 43.4

    2nd 2.132 10.6 25.1

    3rd 1.397 7.0 16.4

    4th 1.000 5.0 11.8

    5th 0.77 3.84 9.0

  3. Also what years?? Axles have changed over the years.

    From Maxi-Drive catalog

    Salisbury (110 to 1994) with drums. 665 and 985 mm

    Salisbury (110 1994 to ~2002) WITH DISCS 650 AND 970 mm

    Don't show the 90 numbers, but again they would change when 24 spline came in.

  4. Well I am on my third 300Tdi and have driven probably hundreds of others and they all take ages to warm up but the new (post 99 export spec) ones seem to take even longer than the old ones did. We have a Toyota Surf on the hire fleet at work which warms up nearly as quickly as my V8 Discovery, probably a quarter of the time it takes my 300Tdi to reach full "needle in the middle of the gauge" operating temperature, so it obviously is possible to make diesels that warm up quicker!

    Well I have a 200TDI and have driven many. It warms up as fast as any other diesel I have driven (I also own a VW diesel).

    With a diesel, you need to do some work to warm them up and then it is as fast as a petrol. If you idle it cold, it will never warm up, plus it is REALLY bad for the engine.

  5. I have never understood why Land Rover cannot make engines that warm up quickly when anything else in the world warms up in 2 min - I was in a Ford Ranger the other day and was amazed that the heater was blowing warm air after just a couple of minutes idling, you could leave a Tdi idling for 20 min on a cold day with the viscous fan removed and you still wouldn't get any warm air. I can't figure out whether the engines are just too efficient, whether the thermostat or circulation design is completely wrong, or what it is, but the diesel engines all take ages to warm up and always have done.

    IME, the warm up time is no different than any other diesel engine.

  6. Actual compressors are between isothermal and adiabatic.

    For adabatic (no heat loss) compression of air:

    T2 = T1 * R ^ ((K-1)/K)

    K = specific heat ratio = 1.4 for air

    R = pressure ratio, say 2 for 15 psi.

    T1 = Inlet temperature in K = 300 K

    T2 = outlet temperature (K)

    T2 = 300 * 2 ^ ((1.4-1)/1.4) gives 93 C worst case with no heat loss during compression. In addition, the water vapour in the gas reduces the temperature increase quite a bit if saturation is reached.

  7. Yes, but the flowrate of air is the engine size and the turbo pressure. The maximum turbo pressure is regulated with the wastegate. If you have not changed that, then the flowrate and temperature of the air leaving the turbo is no higher than stock.

    When you increase fueling the air rate stays the same. The extra fuel is supplying the extra power by itself. In order to add more air, you need to do things to the turbo.

  8. Will see what the smoke situation is like later! My worry is that it will affect the exhaust manifold. Is this likely when its coupled to a uprated intercooler?

    Andy

    Certainly....

    The intercooler only controls EGT if it is not cooling the air enough. At stock boost levels, the stock instercooler is more than enough.

    Don't hold your foot to the floor until you get an EGT gauge. Mr. timebomb we'll call you.

  9. By the way I would personally like to offer the award of All time Tw*t of the Century to whoever was responsible for the positioning of the bolts to the engine mounts and the bell housing nuts - particularly the one directly under the starter motor which required the removal of the driver's floor to get at. Rant over.

    The method in the workshop manual (which I find easier) is to lift the engine, remove the engine mounts and lower the engine down without the mounts. All flywheel nuts are then accesable....

    As to the flywheel housing, you should be able to seal it with any normally sealing method that suits your fancy....
