    Tell me this, is it really that good. How much difference did it make compared to Air to Air or no intercooler?
    I'm a little sceptical as no one has any data to back up any claims. I need to drive a few intercooled 4BD1's and a WTA to make my own mine up right Who else is running WTA here?

    Mine suffers a little at hwy speeds and egts will get up to 600 post turbo wile towing on long hard hills. Only running 8 to 10 psi boost. I seem to notice a small flat spot at 2800 RPM? Always has done this.
    Otherwise goes very well. Very responsive and plenty of poke for off road other than the short fall of max RPMs 3200.

    Tony.
    I'm hoping to be able to get some figures shortly, by conducting a Dyno run, when I get some free time. It should be easy to test, just switch off the water pump, let the heat build up to a normal operating temperature, and give it a run. Then run it with the water pump on.

    I have my fuel setting fairly low, but a tweak up from standard ie half turn. At OAT 27'c; on a long hard hill, EGT post turbo reaches no higher than 425'c at 12PSI.

    I knew you wouldn't be able to resist that post, but you did catch me out how quickly you responded Brian.

    Yep, mine is laggier then Tony's, but after stripping my RR the last few days I found 2 large holes in my intercooler goes to show, anything that can rub will!!

    I'd also be very interested in before and after results

    'anything that can rub will!!'

    Wish my missus had that motto more often, s'pose if you were running fluid in it, you would've picked up the leak?, whatta 'bout the boost guage?.

    ASA I can arrange it, results won't be b4 and after, just off and on.

    On the bright side, air will be leaving those holes at such a speed that nothing else will get in.

    I adjusted my boost and that dropped my egt's, I am running 15 psi now on cold mornings it hits 17 psi it loves it but the egt's don't get as high under acceleration

    Most definately, reasonable size holes, no lack of boost, remained a solid 17psi for the last 40,000kms
