    the Ford team had to design the tdv8 to cope with 45 degree gradients and traverse 35 degree side slopes as well as wade through water 500mm deep.....

    (Apply your indignant sarcasm font here)

    Out comes the calculator... oh goodie now a landrover with a new blue oval tdv8 can do 50/38.8% slopes as compared to the normal 60/40% and the engineering problems youve got to face when redesigning a sump to handle being suspended about 5-6 cms above the water are sure phenomenal. Not to mention that this is a brand new problem that no-one has ever faced before..... ever... no one has ever operated an ICE with it rocked off axis by more than a couple of degrees

    Bloody landrover drivers want these things to be able to move and do it at funny angles with water about next they'll be wanting some kind of dust filtration cause they want to take the things onto dirt roads..Cant wait to charge em a fortune for inventing that.

    And you need to redesign a lubricating system to deal with lubircating the turbos on angles just incase they wind up below the level of the sump... ummmmmmmm hang on most lube systems run at 40 psi, sure if you put the turbo far enough below the sump the oil wont be pushed back up into the sump because of gravity acting on the fluid... Assuming engine oil is a dense as sea water (it isnt) this means your turbo has to be at least 20m lower than the sump before lube flow even contemplates thinking about becoming an issue.

    Perhaps they mean that they redesigned the pick up lines to prevent cavitation during angled operation. Call me pedantic but some easy to get to cheap to replace turbo bearings are pretty much last on the list of crap i want lubircated properly... theres a couple of little things Id like to see lubricated first, nothing really critical to engine operations, little innocuous things like say big end bearings, crank mains, the cylinder walls, gudgeon pins, cam bearings and lobes, timing gears/chains.

    With new sound proofing its quieter than the old engine... hey Ive got a dumb idea what happens If you apply the new sound proofing to the old engine.... tell you what you make me an engine that runs quieter without new sound insulation technology and I might be impressed, but only if you can do it at the 60/40 % slopes im used to with water being flung everywhere with the engine revving its nipples off till then I'll keep my old clanker 2.25 diesel.

    (end your indignant sarcasm font here)

    Sorry gentlemen IMHO this fits into the catagory of cheque book journalism.... Theres nothing new in what they are doing and they want credit for it. Punch it up along side a set of specs for other engines and well apart from lots of torque and ponies it doesnt have a whole lot going for it.

    and the simple answer is,,

    dont buy one.


    not many things in this life are USED to their extreme limits--

    possibbly the space shuttle,, usually formual 1 cars,,

    but not your 2.25.



    maybe it may surprise "us"

    maybe it will sell millions --

    maybe the rest of us "just want one"

    Ok now ive had my cranky go at it...

    while its angle limits are not in line with what Id expect from a rover donk...


    The torque numbers look nice and if its got some of the other innovations that GM/Ford/BMW and volvo (think ceramic skirt liners, the piezo electric push injectors and the new poylmer plasticy/rubbery seals) have been coming out with It'll be quite a capable lump... I wouldnt want to pay to rebuild it tho...

    And the limiting factors for the slopes will be the angle of the V once you start to tilt it the sump oil will begin to pool and encroach on the bottom of the pistons. Bad enough that you have the con rods and big ends stirring the mix but once the piston skirt starts slapping in your in for big time areation and thats bad for lubrication properties.

    Heres hoping the blue oval boys have done the homework and set it up so that its dry sump ready assuming that the lean angles are limited like I said above thats gunna make it a sweet sweet donk, fit the dry sump and with no oil sloshing around inside the engine you could just about run it standing sideways.


    So its got lots of ponies and bucket loads of torque in standard trim, DYNO maps people DYNO maps... Not much good as a 4x4 engine if it has to do 30,000 rpm to make peak torque.

    Methinks thats why its not coming out in the deefers, it might be great hooked up to an auto while its spinning away but with a manual and the need to fineese it at sweet nothing rpms perhaps its a little piggish in its response?

    Give em some time and some of the Rangie/Disco owners complaining about this when lugging off road and it will probabley get sorted then lo, brand new already tested and shaken down TDV8 ready to go in the defender.

    I still reckon when it comes out down here, I'm still gunna take one for a test drive...

    I just want that torque in my 110.
    It would be unstoppable.
