What's the best radiator set up?, Most efficient set up for overall cooling, airflow ect... Options

[Fastcruisin914]

I am doing a Subaru conversion, and am looking for the best proven cooling system.

I have seen the Renegade Hybrid kit, worth the cost??? I have also seen some refer to Desert hybrid, are they still even around or doing 914 radiator kits, and if so are they any good?

So many factors like, front trunk radiator set ups, or rear truck set ups?

The angle of the radiator in the front truck, straight up against the front saving trunk space, or sitting back further and angled, or even in the floor of the trunk?

Also with the air flow, big cuts in the wheel wells, or many holes in the wheel wells, or venting through the trunk floor, or through the hood with the air going up, what is the best way for the air flow without taking from the vehicle structurally?

Pictures would be nice, or even something that may show the step by step process from start to finish with the cooling system install/fabrication.

Rennegade kit is worth the money. Contact renegade for your questions.

Andrew,

Can you send me the details on the R.H. radiator system such as dimensions, Inlet and outlet sizes and rad type (number of rows, if cross flow etc...).

This hot summer has proven that my system cannot handle it. I have some good components such as a 2000 cfm, 9 blade fan out of a Ford Taurus. The remote mechanical water pump is a standard R.H. unit. I also have a Griffin radiator, model 125241-H... no radiator cap (inlet=1.5" and outlet=1.75").

The dimensions are 16"x 27.5" x 3". it is a 2 row unit. Although the inlet/outlet sizes are different, the hoses carrying coolant from front to rear are all the same size at 1.25 inch diameter. The Tech rep at Griffin seems to think that the rad should be fine but I ain't no 4 core unit either.

The other part of this is the car has a Chalon kit installed. I question whether the bumper opening for rad air is sufficiently sized. The opening is ducted to the bulkhead opening. The inner fender walls are fully open to allow the air to exit.

From all that I've read; the viable solutions is to either go with a RH rad setup (or as close to as possible) and/or go with an electric water pump. I think I have some (most) of what RH would sell me as there rad kit. The only difference I can see is the rad size/type and the bumper opening size.

Pictures of my current setup can be found here:

I feel like I am close to getting this figured out. Just a bit more tinkering is needed.

Thanks!

What driving conditions? Stopped, city traffic, highway speeds? Each one is a different cause.

It seems to get hotter the faster I go, even at a constant velocity. At stops, it seems to cool off a bit. Water flow isue then?

Yeah you have a flow problem or giant air pockets in the line. Get the Meizere remote mount water pump place it at the bottom of the radiator use one inch line in one direction and inch and a 1/4 in other direction and you should see significant improvements
