intercooler question

[TDsamurai]

So heres my intercooler from a early 90's diesel mitsubishi pajero.



I would like to know if anyone knows what the bottom tube on it is for? it doesn't go anywhere, its kinda in the way for what i am doing with it think i can take it off or does it do something important?

Was it connected to a bypass valve? I have an IC from an s13? nissan I think, right where the stock mounting location there is basically a tee, one 2" side to or from the motor and 1" side I presume for the stock bypass valve.

I dont think so, it looks like just a T that splits to a dead end. I never took it off the vehicle but i dont think there is anything like that.

oil drain?

  Careful, that's a sore subject...

That is an air/air intercooler, right, not an air/water?

[TDsamurai]

yea its just air to air, theres no fittings or valves connected to it so it cant be a drain.

[mystery3]

If it's just a capped off tube it could be to reduce surge in a similar manner to a water hammer reducer thing used in residential plumbing? Giving a little room for air to compress without straining components. Is the mitsubishi pajero a gasser?

[TDsamurai]

its a diesel intercooler, yea my guess was something to do with pressure surges or something. It hits my radiator overflow bottle when i put it where i want, so i would like to know if i can get rid of it.

[mystery3]

I'm not sure why there would be a "surge protector" on a diesel, I thought the main concern was about the throttle body slamming shut and having nowhere for the pressure aside from a bov/bpv but this would provide some extra space for compressed air.

Considering I/we have never seen one like this I think you'd be safe to remove it. It looks like the IC is all alloy with no plastic end caps to blow apart?

[TDsamurai]

yup all metal, and theres even i nice little fan built into the backside. got that unit for $75

Nice little cooler.
looks like you can get rid of anything but the in and out ..
Put it over the engine and use a subaru scoop .. works great...easy to plumb

[TDsamurai]

not quite enough hood clearance in the samurai to go centered, gonna be offset to driver side not sure what type of scoop to use yet might make a custom one, i also found a 2000cfm 10" fan from perma-cool that will be a good upgrade in the near future.
