Intercooler, Dust & Mud?

Skip,

Thanks for your answer - still seems odd to me though lol

At "30k/h max speed" most well take the intercooler out of the loop, I wouldn't think much air flow would be crossing over it to transfer any heat, you think?

Richard,
the question asked was "do the intercoolers suffer from dirt" and my answer was "NO" as Paul in the previous said.

To answer your question on the amount of air flowing over the intercooler, here it is.

1. Stand in a 30klm breeze and see how much air flows over you.
2. Add another 10 to 15 KPH from the induced airflow by the primary vent fans. That is now 40 to 45 kph flowing over the intercooler.
3. These vehicles are hauling up a 1 in 6 and 1 in 7 decline for 5 klm's which make them work, you can hear the fan cutting in and out.
4. At some stage in the life of the vehicle, you will have to clean the intercooler the same as an aircleaner, but from what I have witnessed that is not going to be very often.

so in other word you believe that it would still be reducing the air temp at 30 kph, thats good to know, as when I drive out in the desert thats the speed that I'm at most of the day.
As for dirt and mud, at 30 km/h we don't kick up much.

Thanks

Richard,

you may not kick up much dust at your 30 kph, nor do I.

Where these utes operate the dust in the air can be so thick you wear a mask most days and sometimes you have to slow down, even at 30 kph cause you can't see.

After a day it is not uncommon to wash a 100kg of mud from under the utes. At 30kph you still get water over the bonnet when you hit a puddle, those puddles maybe 300 to 400 deep and be 30 mts long.

As I said the intercoolers are fine. I will say this again, I answered the post and I don't know where you are going with this, at 30kph the intercooler won't be as effective as it would be at 100kph, but I will leave that to the rocket scientists.

here are some old photo's to give you an idea of what these vehicles live in and look like.

I'm and ex earthmoving fitter, I've have seen a couple of things in my time,
the comment/question below was said without much thought. Nissan people put fans on theres.
"At "30k/h max speed" most well take the intercooler out of the loop, I wouldn't think much air flow would be crossing over it to transfer any heat, you think?"

Anyway I see/know where your coming from. cheers

and don't tell Phil G that they run splits on underground Toyota.. LOL

Regards

Richard

Richard,

the photo's are at least 16 yrs old maybe even 20, I can't remember. We haven't used splits for at least 5 yrs now, we still have some lying around as vehicles have been delivered with them on.

Word is Willem has been seen over here stealing all the split rims.

No what you mean about a fan for low speed to get the best out of the intercooler.

Have a good one

Thanks all for your responses - cheers Paul

same with some of the Pajeros, got a mate who just had dramas with his Paj not running right. he ended up taking vehicle to mechanic who removed the intercooler and showed him the caked on mud from our adventurous day out at Glasshouse Mtns. a few weeks earlier. he gave his fourby a good hosing when he got home from our day out, but obviously missed the very important low down mounted intercooler that was full of mud.
