Intercooler size HDT engine

[syche]

Hi Everybody,

I have seen many threads on this forum and others about Intercoolers for HZ-"Turbo" and HDT engine. But i never really found the perfect size for this engine.

I am looking for water to air intercooler for low speed efficiency, to fit on my expedition HDJ 80 GX with no body lift. I will run boost up to 15 PSI max

I know Denco use a 4x10 PWR barrel. But i do not know what AXT use for barrel size.
Some guys here said it was too small? Is a bigger one fit? Something like a 5x6 or 5x8 from PWR?

The 4x10 is already rated to 300HP, and i don't want much more than 200HP on my HDT. So..is it really undersized?
The 5x..would't it be overkill?

On the other hand i saw a decent HZ modified turbo in Newzealand with a frozenboost 9x3.5x3.5 barrel, and the guy was very impressed with it. is it still too small?

Frozenboost has a bigger barrel, smethign like 11x4.5x4.5...?

Well, i am completelly confused on witch IC i should go for.

What are your experiences with frozenboost water IC?

Too small is not good and too big as as well, so, any of you have good experience of input to help me to decide what to go for.

looking forward to your help

HP ratings for intercoolers are meaningless.
The best way is simply to install the biggest intercooler you can easily fit.

Remember that you still need a radiator out front which can shed the same heat that an air/air cooler would.

currently fitting an water to air i/c to my 1hdt and the biggest rad i could fit in the front was 600x350 core size with tanks came to about 700x350

Hi Ledgend80,

I am interested by your setup, what Intercooler are you installing?

Do you have any pictures? How did you work out the connection to the intake manifold?

For the water cooler to mount int he front, it is not a problem, i have manual gearbox so no oil cooler or things that block the way.

But i can read everywhere, the bigger, not the better so..

Myth and rumour.
I have yet to see a turbo engine hobbled by fitment of an intercooler that's too large.

hi syche

i have a manual 80 series cruiser although there is alot of room up front it is still tight fitting the rad up front and then with thermos it starts to touch the front apron. i have got 2 plates made up (1 is a spare)
that is the same as the intake manifold. made out of 12mm aluminium i will then weld the cooler to this. no pics as of yet but when i get more done i will take some. where in the world are you located.

Hi Ledgend80.

I am very interested into your system. I am actually working on my manifold plate at the moment, trying to figure out the best and easiest design.

What IC will you used? 100% custom or some PWR or Frozenboost based?

What size will it be?

question regarding air/water intercoolers: is there any benefit to a larger reservoir?

Generally speaking I don't use the boost much offroad, but for the occasional muddy stretch it would be nice to have intercooling... so I was thinking that using a reservoir to hold the heated water would allow me to get more efficiency out of a front-mount radiator without adding more fans.

My ultimate goal is a water/air intercooler with a hood scoop that can direct air across the intercooler/turbo during higher speed driving, and a radiator up front, next to the factory aux. electric fan. I believe this would be a best of both worlds scenario.

Yes, the hood scoop is probably not necessary, but I like the look. And more air going across the turbo can't be bad, right?

actually there is someone here running any kind of intercooler in a 1HD-T engine .. ?

 

[lshobie]

I have the PWR 4x10 barrel intercooler on my 1HZ, I have a cruiser pick up and mounted the intercooler rad and fan behind the cab on the upright part of the deck. The rad size is 2 inch thick by 12 inch square and it barely even gets warm when I am flogging it. bQ8aF

it would be trivial to sling a rad under the roof rack... I'm sure someone has done it.
