I am assuming the coolant temps above are the engine radiator temps also? Who out there can clear this up? I have PM'd Johno90 but he isn't a regular visitor it seems.

    Thanks Bene, this is the system I am looking at. Only thing is the results seem very short lived if you read the reviews - keen to understand if the same results will be sustainable over a longer period, say 8hrs of driving? The recovery references are all related to drag race events. Plus still at a loss regards the function of the hot w2a radiator in the loop - must be missing something.

    OK, so made contact with FIinterchillers and yes, they delete the front mount radiator as it simply heats the water up, so my thinking was correct. Anyway, finally got the size of the interchiller unit from them, and will see if it will fit or need a custom unit. They have a fair bit of info on the website about their design without giving too much away, which is fair enough. Now on the hunt for either a PWR or a Plazaman w2a unit and pump. Seems a high flowrate pump is best, waiting to find out if the water loop needs a reservoir of any sort to increase the volume or not.

    not sure who did it but someone shot the intercooler with a c02 to cool it off real cold to see the gains and they actually lost power on dyno the theory was the charge was to cold cause the diesel not to ignite properly..just a thought

    Don't think I would place much credence in this. These diesel will run quite happily in minus 20 deg C as long as the fuel does not gel in the lines. Cold air and even colder is the win. maybe they pointed the co2 at their own head to see if the dyno numbers were going to be better, but they felt worse afterwards?

    Yeah, well, no details, so dismissed already. I have no doubt the effect for me will be decreased EGT's which is what I am after, There is documented evidence that power gains are certainly achieved. Have a look at FI Interchillers to see how they work. I have ordered mine already.
