Hi:

Is this the 3 core Honda radiator setup referred to on this site?

http://www.ebay.com/itm/3-ROW-CORE-ALUMINUM-RADIATOR-12-BLACK-COOLING-FAN-92-00-HONDA-CIVIC-EG-INTEGRA-/350589900140?pt=Motors_Car_Truck_Parts_Accessories&hash=item51a0c9556c&vxp=mtr

If I up grade the rads and fan this year, I only want to do this once.
Is there a LT / RT mirror image version or just 2 of these and plumb it.

Check into dual pass radiators.
It doesn't look too convenient to use the Hondas because of the fill cap and hose placements. The dual pass radiators put both inlet and outlet hoses on the same end of the radiator. The water passes twice through the core horizontally and it is said the dual passes improves the cooling. We need everything we can get.

And don't use anything but Spaal fans. They are OEM and are readily available.

Are you laying the rad long length Horizontal or Vertical?

When making a fan shroud, how far off the radiator do you go, 0.25" or 0.50"?

I have Griffin Quad Core but the fans that came with them are SPAL 600CFM which I think is way too low.

I believe the rads can pull the heat out of the fluid ok but the fans cannot get it off the rads quick enough. I am looking into 2.5" low profile 1200 to 1600 CFM Pullers (from fan towards motor).

db, I don't really know the correct answer to your question about the spacing of the fan shrouds, by my two cents worth is that there should be no gap. I'm planning on fitting my shrouds to the radiators with some closed cell foam insulation in between (so the shroud doesn't actually touch the radiator and rub a hole in it). My thought is that the air will take the path of least resistance and if you can cut out all the paths other than through the radiator, you'll get better cooling. I'd be interested in what others think as I'm just trying to use logic here.

Yes you are correct for the edge clearance of the shroud to the perimeter of the rad. I was curious about the face the fan mounts to and the clearance to the rad.

The radiators I have came with fan mounting tabs welded onto the radiator frame. I used some 1/8" sheet aluminum to fabricate adapter plates since the holes on my Spal fans did not line up with the holes on the mounting tabs (these mounting tabs were made for 10" fans and I'm using 13"). Anyway, with the additional 1/8" for the adapter plates, the face of my fans sit at 3/4" away from the radiator coils.

Hey DB, I don't know if you've seen my post about using the radiators you're asking about, but I have a pair of them. As I get my LT1 installed, I'll let you know how it goes. I've seen others say these work but you have to open the front air space to where it can flow more air into the rads. We'll see. Once my parts come in from Archie, I'll get busy on getting the car to a drivable chassis state.

Thanks,
Coop
