    But I think I've done really well.
    Yeah its got fibreglass fibres in it.

    Hi every one, i have been reading all the thread and im happy to see you having good results!!.
    i know you already covered the EGT gauges topic, i fell in love with McNally but it goes over the budget i was contemplating
    Hope you guys could tell me if this one i find on eBay will be relyable, i like what it says on the description.
    Thank you for sharing your work

    The best solution is to get the dump pipe ceramic coated , think thermal dynamic
    this will keep the heat where it belongs inside the pipe.

    Boost was still all over the place though. Jumping to 20 psi, then dropping to 10 then building back up to 15-16 psi - all while maintaining the same speed on a flat.
    Fitted one of mudski's dawes/needle kits over the weekend and it stopped the erratic boost issues I was experiencing. Car is much nicer to drive with a smooth boost curve.
    I used the instructions in mudski's kit and had everything up and running in a couple hours - car sits nicely on about 15-16psi at full boost and on 10psi at 100k's.
    EGT's stay around 200-250 around town and only hit 400 when I'm right up it and drop again pretty quick.
    I had my exhaust fitted by Berrima diesel and I see they cut the original heat shield in half to fit in the new dump pipe - worked out ok 'cause I had to get the egt probe fitted at a later date.
    Interested to hear if anyone has tried any additional heat shielding - I heard sometimes the heat under the bonnets of gu's sometimes kill the aux battery - so far so good though.
    I have a turbo beanie fitted so now I have no problems of the AUX battery getting to hot

    I stuck my hand down there after a 30 min drive and yep, it gets hot down there. What have others done here? There's that exhaust wrap stuff, I was thinking of wrapping that around the heater hoses as they are pretty close to the turbo. Does that stuff work backwards like that??

    I was hoping to rig up some ducting from the front and point it at the area, but I'm not sure I'll be able to do that, there's not a lot of room.
    Just cut a hole in the heat shield where the probe is. Simple.

    Yeah I know that's the best solution, but I'm lazy and I have to remove all them hoses and get my floor wet and my fingers dirty, then put it all back together again. Maybe I'll give it a go ;-)

    Got my boost gauge today and the dawse kit from @mudski yesterday.

    Got a peak boost of 17.6 yesterday taking off from a dead stop up a hill on the dirt. Boost is sitting on 10-12 at 100kmh, down from 13-13 pre zorst install.

    Thats with the kit installed yeah? If so, I'd probably wind in the needle valve just a touch to get the 100k boost at around 12, and a little higher. The spool up on the turbo will increase a little too. But. You may not need to touch the needle valve though, if you think its fine. When you get the EGT gauge in, have a play around with the needle valve and you should see a difference in EGT's at 100k's with different adjustments.

    Go easy if your going to use an exhaust wrap especially on a 4x4,
    you'll find it will rust your pipes very quickly, if subjected to water.
    Even race car and nascars dont use it for that reason
