  1. I have used Richard's in the past, fitted 4 or 5 of them now and wouldn't use anyone else. slightly steel, decent galv, no runs, no holes to clear or retread and everything lines up. 

     

    by comparison the shoulder bulkhead we had for last rechassis needed 13hrs of fettling work to get it to fit. major issue being warped in the  middle and bowing in. the time consuming issue being each an every square hole of screw plastic inserts had to.be filed out.

  2. was googling trying to find a max acceptable boost level for my 2.8tgv.

    the vehicle is running an uprated intercooler and tweaked pump.

    it used to max at 720EGT.

    i recently changed the VVT feed from the outlet of the turbo to the back of the manifold so the vanes now change with respect to the pressure at the back of the inlet manifold rather than at the exit of the turbo compressor side.

    Massive difference in driveability of the vehicle and EGT are generally down as more air is now going in for any set fuel delivery relative to pressure. (as i understand it)

    Also decided to fit a boost gauge at the inlet manifold feed. 1.2-1.4Bar so too much for a tgv head? anyone know how it would fair on a 300tdi head running at 1.2 to 1.4bar? (17-20psi)

  3. synthetic should be spooled on under load to avoid it biting down through the layers. if you have to spool it on loose. like having pulled out more than is required to get to the anchor point when you are stuck then criss cross it back on, once will do then it will only bit to that cross. after the next loaded pull, unspool the rope back to where it was criss crossed and spool it back on under load.

    the problems of not doing this were highligted to many when freespool drums first came to the competition scene.

  4. i am still lost as to what your issue is here, its an event based at a farm in the national park that has a greenlane excursion as part of the event. there is no mention that the greenlane trip is in the national park.

    So you have one bit of info about the National Parks lanes being out of use, i accept that, thats great, what i meant was have you actually researched the rest of the event. ie asked them where the greenlaning is taking place, looked into what they are actually doing. I guess not.

    its easier to just criticise and make assumptions i guess and try to paint a bad picture at others peoples expense when you have nothing to loose.

  5. Durite voltage sensing relay to connect two up think it switches at 13.6 and drops out at 13.2 or similar. fit that in the charge wire between +ves

    then have a second wire to bypass the switch with a hand switched isolator on 35 or 70mm (depending on other wiring in vehicle for winch) to link the two togther when winching or for jump start.

    or use a winch solenoid as the isolator

    i use 2 x Numax leisure MF27s.

  6. I've blown a few motors competing. There's 2 reasons really. Over reving, which isn't going to happen on a husky! The other is heat! Working hard & long will make things hot, as will a battery that's a bit tired or flat. Motors don't like working with low volts.

    Cheap motors, even warn xp's use soldered comutators, the solder melts, end of motor.

    One main reason most challenge competitors use bow motors is that the coms are copper braised.

    ^^^ what he said, overloaded i think

  7. i have a defender 200tdi in an H reg 110 with a 6 bolt box.

    it needs a new steering box.

    as you cant easily get 6 bolt boxes, i was thinking of fitting a 4 bolt box.

    Does anyone know if the current pump and therefore pipework will fit? pump is NTC8287

    if not what pump and pipe work would i need to match the 4 bolt box?

    many thanks
