horizontal radiator

What is the effect on the efficiency of a radiator when it is installed horizontally rather than vertically. I've seen them installed flat in competition division dragsters but rarely in rods or customs. Seems like it would allow for more creativity if it can keep the engine cool.

Crossflow rads became more popular when the cars got lower and wider and need better cooling, because of bigger engines and more accesories, like A/C etc.

They cool more evenly accross the rad.

You can mount in horizontaly but just hasnt been much of a need to do it. You'll just have to fab out some mounts make sure your flow is enough and some other minor details but if you really wanted to its possible.

Kind of hard to fill with the filler half way down the side of the tank.....if you want a crossfow rad, you have to get the right thing.

Shoot, I didn't state the question clearly enough. I'm wondering about mounting the the radiator FLAT - as in parallel to the ground. Like I say, I've seen it done in some diggers (where track rules do not allow racers to be towed back to the pits) but can't recall seeing it anywhere else.

cboy, you asked the question fine I think it was just mis-read. Sure you could do it but, you will have a few issues, the main one being air flow, you will have to make some sort of ducting to get fresh air to the fins. Filling it would not really be an issue if you use a remote fill on it, very simple to fab up. I just don't see where it would really be worth the trouble to mount it flat. What will this gain/save you? In a dragster there is really no other place to put it and looks don't realy matter. Besides in the bed of a truck I can't imagine anywhere else you would want to relocate it to.

Thanks Royce,

It was somewhat of a hypothetical question resulting from designs/drawings for a new project with a fairly radical (long and squatty) nose up front. Just trying to figure out how far back I could tilt the radiator and still have it function properly. If I can lay it all the way back to "flat" - you have answered my question.
