Anyone familiar with dual pass radiators? I'm curious if anyone has ever tried one in a FD.....if not is there any particular reason why?

What do you mean duel pass radiator? Do you meanest up like the RE radiator where it has two main chambers in which it cools the fluids and remixes inbetween?

SPOautos

Well, that sounds similar....do you have any info on the RE radiator? Where could I find some info on it?

Basically, my understanding is dual pass the inlet and outlet are on the same side and the coolant goes across then back across staying in the IC twice as long. They tend to cool much better but for some reason I'm not familiar with anyone that makes them for the 7 and I'm not sure why.

Just trying to do a little research. If you have any info on the RE I'd love to see it.

Thanks,

I don’t have any info on the RE one persay, but that’s how I made mine run. Technically the water will be in the core the same amount of time though if it is the same volume. Chucks runs down one side( ½ the core) then mixes in the bottom tank then travels back up the other ½ of the core.

The reason for that setup/design has to do more with clearance issues and ease of setup than it has to do with pure performance.
I have one that is setup like that for the same reasons, although mine is setup a little different from chucks in that it keeps the hotter side of the core away from the intake to help keep IAT down.

Well, I'm talking to someone about a design using a dual pass radiator that should be pretty nice, he says there shouldnt be any prob using one. THe only thing is I've read online that they are more restrictive (makes sense too) and I'm wondering if that could cause problems with the water pump. Especially for someone like me where there is no air pump and the water pump doesnt have much traction on the belt.

The place I'm talking to says its not really any more restrictive if it has a good tank design.

I was just hoping someone ran one or knows of one for the FD that can chime in and say if they had problems or not.

So your saying Chuck's selling one? Is it for the V mount or just a upgraded radiator in general...also, I'm not following your description of his. Why did you get a dual pass? Does it cool pretty good? Have you noticed any cooling issues at all? Also, if it isnt made spacific for out car how did you get it to mount up?

It sound like the one you are describing would keep the fluid in the core longer, sounds like it just runs the fluid through to make it cycle longer in the core. I don’t know what effect that would have if it where the same volume core though.

The one I am describing to you is just a standard radiator modified to flow from the top tank down one ½ the core, mix in the bottom tank, then travel back up to the top tank. Nothing fancy just a different way of running the fluid through it.

SPOautos

When you say "down one 1/2" of the core do you mean the coolant only goes 1/2 way across? Thats whats throwing me off, I dont understand how the coolant can only go 1/2 way across.

Did you have your radiator custom made? Who made it?

paste the link into a new window without the [/url]

If you look at the pic you will notice a weld that runs along the center of the top tank, there is a divider in there and the bottom tanks outlet has been welded shut.
