More power and better fuel economy - now that really gets my attention. Has anyone here actually installed, or had installed, an intercooler on a 1HDT? If so, what system and where was it installed? What kind of fuel economy improvements did you see? I've seen the prior thread on a cheap "intercooler" but I'm looking at proven systems like the Safari. I just might do something like this if there is any local experience with the system.

Hi Martin.
For experience and data try the 80's cool list http://www.lcool.org/
I know Marko from Outback installed a Safari intercooler on his personal rig as a test. Dunno if he retails the kits. Once you start tweaking the engine, you are going to have to deal with the tranny.

I just talked to my friend Dave who was on the phone with Mike today. Mike decided not to go the intercooler route given all the additional problems this creates. It looks like Marko is the only one at present, and he appears to have very deep pockets, or at least a lot deeper than mine! I hadn't thought of all the other upgrades necessary. I'm not sure I want to take on the expense of upgrading the whole drivetrain as well. Perhaps this idea is not such a great one. Thanks for the info. I'd still be interested to hear from anyone that has actually done this and what the results were, though.
If all you are wanting to do is lower EGT's and maybe just a little boost increase, why would you need to do all that other stuff? Once you install a intercooler, you will need to increase the boost to get it back to at least before intercooler boost pressure.

Most intercoolers have less than 1 psi pressure drop across the core. The difference will be negligable in boost "loss". You should have MORE power because the air will be cooler. Cooler air is more dense = more oxygen = stronger combustion.
True, but there is all the plumbing and how it is routed(bends) and clean or dirty connections and such. When I did my intercooler, the boost droped at least 2psi.
Also, if your diesel recerculates the gasses from the valve cover and you leave this in, then the dirty air will coat the inside of the plumbing and intercooler, therefor slowing down the air.

Perhaps, but the power gain from the cooler air should offset this completely.
Also, once the intercooler is fitted you can run upto 20psi easily if not more.
Intercooler-less, the ceiling boost limit is 12psi.

Just wondering, why can you run more boost with an intercooler?
And why is the limit of 12 psi without?
I have noticed people with intercoolers run more boost, but I am not sure why.
Thanks,
Nick

The turbos job is to make the air denser. The act of compressing air causes the air to heat up. Heated air is less dense then cooler air. There is a crossover point where the increased air density from the turbo and the heat generated from compressing the air come up against each other and gains start diminishing. One way around that is to cool the compressed air via a charge air cooler. The air becomes denser, thus provides more oxygen to burn all that fuel you dump in. This allows you to set the wastegate to dump at a higher pressure, as the charge air cooler will look after the extra heat generated by compressing the air upwards of 30psi in some applications.
That is a simple explanation, and I hope I got it right. There is a formula, which relates the temperature of the intake air to the temperature of exhaust air. Supplying the engine with cooler intake air affects the heat load on the engine as well.
I am sure others who can explain this better will pipe up, but hope this helps a little.

Thanks greg.
You did great with your explanation.
I understood what you meant.
Many thanks,
Nick
