    Impressive - and quick. Youve done great work, and those new tanks fit in really well.
    Good luck at the pits (and bring your chequebook!).

    Looking good chap.

    Bet you're itching to get out for a good run on the road?

    Sure am... straight over the pits, then a few weeks of obscene fuel economy and then its diesel time!!!! Just the few blasts up the road remind me why the last went diesel very quickly!

    Conversion plate..

    Whilst waiting to get to the pits, I've started to tackle the job of mating the LT230 to the ZF box. Thought I'd put it in a thread in Projects for a few others who might not get into the world of 101's! Here's the link.. if it works!

    Why are you going with the LT 230 and not the LT95?
    I would have thought you would want to keep the winch capability etc.

    Hi Keith.
    The LT95 is all one piece, and the job of chopping the box in half put me off.. It's the original 101 box, so I don't want to chop it up. Not only that, the LT230 lends itself to the job as the input gear is fully supported, the depth of the box is less than that of the LT95 transfer case, the ZF box I'm using has two PTO outlets, one of which I have a hydraulic pump in, which will eventually run a rear mount winch. I now have fuel tanks either side so would never run the original Noken Winch... Not only that, they're as rare as chooks teeth now, and better suited to a genuine/original vehicle. Ashcroft also do a kit to upgrade the center diff which I plan to do to help it cope with the huge torque increase! The LT230 is easy to work with, has a good flat mounting face to suit sitting on adaptors etc. Cheers for now!

    Lots of good reasons there
    I had a spare LT95 so could cut it up.
    I had to use the T,box off it to get the third axle drive otherwise may have done the same as you.

    The 101's theoretical speed.... Thoughts please!

    Ok guys, I've been doing some calculations today.. The Cummins engines max power is at 2500rpm, so Im assuming flat out would be 2800/3000rpm. With this in mind I started thinking about gear ratios. The ZF box is an overdrive box in 5th... At 2500 rpm, the output speed is 3100 rpm. So here are the figures:-

    1.003:1 Transfer gears and 4.7:1 diffs at 2500rpm I'll be traveling at 112kph..
    1.003:1 Transfer gears and 3.5:1 diffs at 2500rpm I'll be traveling at 150kph!!!
    1.222:1 transfer gears and 3.5:1 diffs at 2500rpm I'll be traveling at 124kph..

    Now, my thoughts are the 112kph option is just a little slow for ecomimy/cruising. I'd like to be doing 110kph at 1500 rpm.. The second option of 150kph at 2500rpm kind of appeals to me!!!! Prob not practical...
    The last option of 124kph at 2500rpm sounds the best... but it does mean 3.5:1 diffs...... which will affect the lo box. That said, the ZF truck box has a fairly slow first gear which would help..... Thoughts please!

    The Goldilocks ratio.
    That's what I'd go for.

    Translating it into UK money, you're looking at a possible 77mph cruise, or 93mph with the 3.54 diffs.

    Pretty sure Nick did something with the governor spring on his to take the max RPM up a bit (the yanks an have em running 4,200 redline with the P pump) but generally run to 3,600. Apparently the governor spring mod stops them backing off fuelling as the redline approaches...

    Anyways, I'd say the sensible option would be 3.54 diffs (more easily available) and the 1.2 transfer box, more than quick enough at 2,500 rpm, and would still run past 90mph before you hit the governor.

    There's also the added advantage that you can fit the input gear out the back of the transfer box...

    Whilst I'm sure the idea of a diesel 101 that will crack 100mph (about 115mph on the governor) sounds good on paper, but I suspect self preservation instincts would kick in before you got into 3 figures.
    You've got a shiney new Golf for high speed cruising, and you'll not die driving it. A 70-75mph cruise in a 101 is more than quick enough...
