Putting a intercooler on a Mu...?

[fred flintstone]

can do, or not..
I'm thinking of doing this,
as well as removing the emissions stuff,
anyone done this?
anything I should know..?
oh, gotta 2.8 turbo diesel

[kaney]

can do, mate did it down south. took intercooler of one of the newer ones and it bolted on.

[Jezza]

Fairly easy mod, I did it awhile ago to my 3.1auto.
Take of the egr and make some plates to cover holes. Get a intercooler from say a 1994 3.1 bighorn, to fit it you need to
loosen the front turbo housing and rotate so it lines up with the input on the intercooler. Fit a hood scoop at the same time
to really get the benefit from it.

[fred flintstone]

cheers for the info, I guess the bonnet of the bighorn wont fit...
I had in mind to get a intercooler, with the bonnet from a wreaker
and try fit them together...
anyone from Hammy have any recommends to a good garage...

[Jezza]

With the bonnet scoop just line it up and drill the mounting holes, then just crank out a angle grinder and cut a large section of your bonnet out. Easy
As for a garage, just do it outside

[fred flintstone]

another question I have, the rev counter,
is this electronic, or cable..
mine intermittinly goes and not,
seems a bump can make the differents...
(yes I've looked, but cant for the life of me, see where the problem is )

thanks for your invaluable help

tacho is eletronic, well it is on a 3.1

i was going to intercool mine but a diesel mechanic aid it was useless untill about 90kms onwards
plus it takes longer for it to boost as the air has to fill the cooler before it can reach engine?

[fred flintstone]

thats a puzzle, as I figure it'l be the same as a bighorn...
or maybe theres no gain..?

anyone??

Yes, you really do feel a large power increase when your going fast, especially going up hills. But it does make a difference when going slow, even more so if you have a fan and/or water spray (but you need a hood scoop)
I've got a boost gauge fitted in mine and I didn't notice any lag at all.

yea it is interesting ae, does it save fuel??
or are you etter off upgrading the exhaust??

I didn't find it saved fuel, if anything it was worse, thats why I just took it off in the weekend.
My car had a 2.5inch exhaust fitted when I got it, so I don't know what it would be like with a standard exhaust

[Engineer]

correct me if im wrong (most likely) but running an intercooler cools the air making it more dense so youve got more air going in which would require more fuel therefore making it worse of fuel...unless its run quite lean? But i would imagine itd be a good gain for performance.

once ive done body lift i wanna top mount an intercooler on my skanky 2lte, not too worried bout the wee bit of extra gas itll use if the gains r noticable.

What the ??????

The cooler is always full of air ... and its compressed as soon as the turbo spins up.
If you go the top mounted one there is no etra piping to fill up so the bost lag is minimal.
I have fitted one to my 2.8 bighorn, and like they have said above it is very easy ...
I found the hardest part was cutting a big hole in the bonnet.
I have not altered the injector pump at all and have actually got better fuel economy.
The cooler the air the more you get in = better combustion.
In discussing this project both before and and after fitting the inter-cooler with a couple of experienced mechanics, their comments were very similar in that you will get the most noticeable gains in power are at higher speeds but you will still notice the difference at the lower speeds too.
If you are doing a lot of low speed, high rev work look at a water spray or Electric fan, both have been done.
I am looking at putting a fan on mine...

tell me more about waterspray, electric fan...

and as for worst fuel economy, why, as its turbo feed air, which is extra power
unless your using all the power all the time, economy should be better off...?

[GotFlex]

That was what was told too me and wondered if anyone else thort the same,
just another point i thort, diesels main idea is they work on heat energy so could this upset the combustion process cause damge possibly hahaha
im just playn devils advocate,

my theroy is people need to stop jumping on the band wagon just coz every1 is intercooling there trucks doesnt mean its guna be good, id rather buy a tank of gas a box of beer and a feed after my hangova!!

[dazza85]

.....
my theory is people need to stop jumping on the band wagon just because everyone is inter-cooling their trucks doesn't mean its going to be good, ...

The model Bighorn that I have came out from factory with and with out an inter-cooler ...
Like anything it's all to do with price, the more you pay the more you get.

Like you I asked lots of questions as to the pro's and con's of doing the job and also had a drive of one that had one fitted in the factory and decided that the increase in power was worth the effort of fitting one.

you conviced me then!!
Anyone have a intercooler???

[Heath]

is the increase in fuel usage because the vehicle now has extra power to play with so ... you use it?

I have not noticed any increase in fuel use ...
If anything it has improved a little ...

Yeah, I'm thinking that is the reason

[quiki]

Thats exactly what it is. If you dont drive hard it will be more fuel efficient. Did the 2.8 come with a factory i/cooler in anything? Just be careful at high speed on cold days. More oxy equals higher combustion temp equals blown motor. Maybe a pyrometer in exhaust to monitor exhaust temp would be a smart plan.
