Intercooler options for 300TDI

[kreecha]

Hi guys,
Just looking at getting a new intercooler for my discovery, purely looking to decrease EGT's without winding down the fuel pump which might have been modded by the PO.
If anyone has used either of these products can you please post your review.
Cheers, Adam.

i have the allard intercooler in my disco, very happy with it.

Ade,
If you have an egt gauge, could you tell me;
Did you fit the intercooler and drive without pump mods? Did this result in lower egts?

Cheers, adam

If you have an EGT gauge set your pump for your ideal smoke/temps/performance using just the smoke screw on top cover and the diaphragm under it.

Its very easy. Screw in the Top grub screw until too much smoke on take off, then back it off a bit. Take out the diaphragm under the top cover and point the shallowst side of the concentric cone towards the front of the car, you now have it at minimum fueling on boost. 180 degress from that position is maximum. Rotate it in increments of 45 degrees checking for changes in EGT under full load on the highway.

You will eventually get close to the temps you want, but perhaps not the performance. If you don't have a free flowing exhaust, you may want to consider that as an option.

Set your pump to sort out your current EGT issues and you can then see how much power you need to find before deciding on inter-cooler and/or exhaust. Fitting either of these would benefit from more adjustment to the pump so you might as well get to know it.

Thanks for that info. I see there are a few pages on different forums, including this one that detail this info and even abit more.

I am still interested in anyones findings with the performance of the intercoolers prior to pump adjustment, especially with one of the 2 intercoolers listed above.

Thanks once again Manic.

I fitted the full frontal intercooler from allards to my 300tdi, it made no difference at all till the pump was tuned

I fitted the full frontal intercooler from allards to my 300tdi, it made no difference at all till the pump was tuned, when i fitted a water cooled turbo later i had to do the mods above to lower my egt, it now tops at 670 but needs a proper tune by an expert[not me]

That doesn't surprise me one bit.

I have 300tdi in a defender 130 with an EMS1 with EGT sensor mounted in EGR plate pushed right down into exhaust flow.

With a bit of weight on and 5 people coming back from Melbourne today the EGT kept tripping alarm at 680deg and would climb above 700 if I did not back off. Backing off would drop temp but also slow down.

I do have Diesel gas installed but makes little difference if turned on or off to temps.
I know the cars history and doubt the pump has been messed with. Maximum boost is just shy of 15psi on gauge

Are these temps normal or is it suggesting a pump adjustment or IC clean?

Thanks
James

[rick130]

James, first suspect is air cleaner and/or a restriction somewhere else in the inlet tract and maybe an I/C clean.

Those temps are what I'd expect to see with an adjusted boost compensator, not a stock pump.

IIRC the highest I ever saw with a stock pump was 623* climbing the range at Murrurundi.

[Discomark]

I also have an EGT sensor in the EGR plate and before tweaking the pump i did a test run up a long hill and registered 553c. After tweaking the pump on the same hill the temp went up to 696c. i have backed off a bit now and now its rare to hit 700c but can happen on really long hills whilst towing.
