12HT Intercooler

[MUD000]

Has anyone put an intercooler on a 60 ???
Is it worth doing ???
Where is the best place to get the parts from ???
What size intercooler do I need ???
Looking at putting a top mount in with bonnet scoop
Pics
Cheers Dan

Your motor would love an intercooler, and something from ebay would do nicely. Put it out in front of the rads, a guy on the list used to have a hdt in his 60 with cooler....he ran the pipes through under the headlights.

I used to have a front mount air to air cooler on my old 60. I think the core size was 600*450*75mm. It was more or less the perfect size to replace the front grill, and it was sourced from ebay. It made a huge difference to the 2h, and i see no reason why it wouldnt make a big difference to a 12ht.

i am also interested in this- are we talking just air to air intercooling? this seems simple- just re-route the air flow to go through a front mount- but if it was that simple why doesn't everyone do it? sorry for being ignorant

Have you got any pics carts
What about overheating as you would be blocking air to the rad ???

mmm... intercooled 12HT.. with a front mount... mmm...

[cruiserute75]

dont mean to hijack but would a top mount be very effective, with a bonnet scoop. obviously not as good as a front mount but would it still make a descent difference. i'd just be worried about front mound as it may make it more prone to damage, in saying that almost every turbo truck at obc has front mount so i dont know???

I am looking at intercooling my 12HT also but with water to air
because there is bugger all space up front when you have an auto fluid cooler as well and the water to air radiator is much smaller
also I know I would eventually get the 2.5 inch ducting in under the headlights etc but I know they will forever be in the way when trying to do maintenance etc
where the water to air barrell can be removed by undoing a few hose clamps and flipping it out of the way
my 2cents
keen to hear from anyone who has fitted water to air denco or similar to anything

how does air to air work? i don't understand how ambient air can get any cooler using ambient air over the cooling fins?? how hard is it to plumb an air to water intercooler? where does the water come from and how is it cooled?

sorry for being a dumbass (;

[rowan]

never mind- i just went to wikipedia and answered my own question-so for those who know as little as me, the air passes through an air to air intercooler AFTER it has been compressed by the turbo (compressing air causes it to heat up.)

so i guess you would plumb it from the outlet of the turbo, through the intercooler and then into the intake manifold. my next question is how much more turbo lag does this extra plumbing cause? negligible? who has done it? where are the pics etc etc etc

cheers carts-have you had that thing dynoed?

did you turbo it and then intercool, and if so was there any noticeable increase in turbo lag from the extra plumbing volume?

if so, what do you think of a side mount in the back passenger side of the bonnet? i'm thinking hot air would tend to escape up through the vent, and thus decrease cooling? would have less turbo lag tho as it's right next to the turbo. could have a vent on the other side where the exhaust is and then the passenger side one with a scoop and you'd prob get optimal air flow-cold in one side, hot out other?

if turbo lag isn't an issue i'd obviously go front mount; what sort / size / brand / model etc intercooler did you use? what are they worth? where do i find one? what diameter piping is adequate? smaller diameter gives less turbo lag but also less airflow? etc etc etc etc

no, i never got it dynoed. But the fellow (sixdeetoo) who I sold the setup to did have it dynoed. It used to keep up with 1hdft great, and beat them off the mark no worries.

I had the car turboed for about 12 months before i intercooled. After intercooling, i upped the fuel and boost, which made a huge difference. Turbo lag was unnoticable/negligible. It was a great setup.

As for piping sizes, that intercooler had 3 inch inlet/outlet, which was more than adequate. You could get away with 2.5inch no probs.

I sourced my intercooler from ebay, and from memory cost around the $200 mark. As for sizes, see my above post. The quality was great for the price.

I didnt have any issues with overheating either. There was adeqaute air flow through the intercooler to allow the radiator to cool. I would avoid a side mount intercooler under the bonnet because i think that would hinder your performance more than help it, seeing as though under bonnet temps can be well above 80 degrees under normal operation. Top mount intercoolers can actually heat the inlet air under some instances, such as in traffic travelling slowly, because of insufficient air flow across the cooler. Hot air rises off the motor.

Carts what sort of EGT's were you running under load? Do you think running 12-13psi will still maintain reliabilty in a 2H? Also how smokey was it with the fuel upped?

[sixdeetoo]

ok fellas - FMIC SETUP as sen on my rig - used to be carts.

its tops and it works.

have a look - lookie lookie











and hopefully all these links are still good.

around the 480 degree mark.

i was running 12-13psi no probs, and if you keep the EGT's down, i dont see why reliability cant be maintained. If you go stupid and run egts around 600, then expect to melt pistons.

like any diesel without boost compensation, it was a little smokey off boost, nothing to be concerned about though. Ive seen hilux's blow more smoke from the factory.

Nice photo's sixdeetoo. I miss my old 60.

I was thinking of running a bit smaller cooler and 2.5" piping, i just can't see that 3" piping and a fairly large cooler would be required for a relatively small turbo and low engine revs...but i'd love to be proven wrong!!

holy crap thats a clean engine bay for a 18 year old car

did you polish the rocker cover lol?

[rowan]

i'm not really chasing big power increases- i just want to lower intake temperature to keep temps down on hot days and look after the engine etc-the power increase will be a bonus. will i have to increase boost to compensate for pressure drop across the intercooler? i.e after intercooler is installed, the turbo will still be putting out the same amount of boost, but there will be less boost at the actual intake due to extra distance / capacity of intake ducting-if i have to muck around with boost and fueling i might just leave it be (if it ain't broke don't fix it etc etc)

thinmk you just run the wastegate line to near the intake manifold, so its sensing the boost at your intake rather than before it goes through your intercooler.
