v mount radiator question
 

Hi I am going to be building a v mount set up for my fd and I was looking at the different set ups and a lot of people have the water inlet and outlet on the same side of radiator and block the bottom off. So my question is this how effective is it to have both water inlet and outlet on the same side, would I have cooling problems.
Thanks

In order for both the inlet and outlet on the same side, the radiator needs to be modified to be a dual pass configuration. Or you can by a radiator already configured like that.

As far as cooling effectiveness, I set one up like this and it's been on the road a year and a half with no problems. I expect it is as least as good as the original configuration.

We haven't had it at the track yet, but we will see how good it is when we take it to the track.

Details in thread titles go a long way in finding information down the road. "V Mount Radiator Inlet / Outlet Locations" or something.

Sorry about that, did not know they were dual pass, thanks for info

Here's a couple pics of the radiator I modified.

I cut the low side of the top tank off, and fitted a divider.

Then I fabricated another side for the top of the radiator

And welded it all together

Thanks a lot,

Just curious if any one can help me figure out how low does radiator have to sit in opening for a oem 99 spec bumper,

So I just got my intercooler, I have to change my end fitting diameter but what if I leave it and get a 2.5in to 3in fittings, would I get better spool because of increases velocity.

Here's pictures of how I mounted it. Its a stock bumper for a '94

The aluminum bracket hangs down 4" from the frame.

Here you can see it aligns well with the bumper opening

Thanks a lot for the pics, BTW on my intercooler I have to change my end fitting diameter but what if I leave it and get a 2.5in to 3in fittings, would I get better spool because of increases velocity. Basically my inlet and outlet are 2.5 on intercooler.

Really it's less about velocity as it is about volume. The bigger pipes do allow more overall flow but cost on "spool time" because it takes longer to pressurize the larger volume. Unless you're building some real horsepower monster I don't think the benefits of better flow would come into play. So it's likely that 2.5" would be plenty.

Ok, that's good to hear as my turbo outlet is 3in
