I think I found Cathars Big Arse

http://webbase.transpro.com/catalog.php?partnum=398348

Only prob is that we are talkin $110 from autozone

Would like components for which there is data:
Thermochill Radiator - both the HE 120.1 and the HE 120.2 - Bill's data.
Delta(1212VHE) and Papst(4312L) Fans - same as Bill used.
Swiftech6002 and "Dtek Whitewater" - P/Q curves and both Die-Sim and CPU results available* - different C/W dependence on Flow-rate.

The object would be to see how well simulations can represent the system
Maybe use 1/2"ID and vary coolant flow-rate on the combinations of these set-ups.
Then use 6mm ID(can improvise the adapters) for a couple of example set-ups


* If Bill's "Little River WW" data is acceptable as representative of "Dtek WW"

Will have to look into that.

Thanks! :cool:

Hmmm - seems too wide. The core I have is definitely not more than 6" wide.

Just did a scan on that database, this is the Big Arse:

Still seems too thick - unless they're including the tank flanges in that thickness...

unless they use a different spec core in the states..... i imagine there's a bit more need for in car heating there than in OZ....

hmm if $110US isn't high enough to deter you, then i suspect that importing them from Oz might be viable ...

The only way I've found in personal fiddling to get around the "quiet fans = poor performance" problem is to add a second low resistance radiator. 2 of the 2-342s isn't a bad plan. But where to fit it then? I use an external box but not sure if that will fly here

But your big arse is only 1 inch thick right? Not 2 1/2"

BA is 1.25" (32mm), not 2.5" (64mm).

Seems to me that perhaps that core I linked to is a double thickness core. The core facial dimensions are spot on, but the thickness is twice as thick.

Quite possibly made by a different factory for the USA cars, and probably quite a different sort of core design. Would be nice to see an actual picture.

Incidentally http://www.radiatorexpress.com/ has either of those cores for ~$65US
