My radiator sprouted a leak that a can of Barrs leak couldn't handle and screwed up my big weekend.

What should I know about sourcing a real radiator? It's a racer with no internal oil cooling needed and I have it mounted slightly inclined and don't mind fabbing stuff, I already have a Viper cooling fan and wouldn't mind a chance to make up some nice mounts and stuff.
Should I be looking at a generic aluminum racing radiator to adapt or would using a 928 specific one from a vendor be a must? What are the actual fitment issues that come up when doing radiator searches here?

The original 31 year old one did cool just fine.

 

That sucks A$$! Good luck...sorry I don't have any rad suggestion.

Side tanks spring a leak or in the core?

Maybe a stock core with aluminum side tanks like Todd has been using.

 

It looks like the side tank seal at the lower left side. The way it manifested itself was the power steering being intermittent because of the coolant making the belt slip.
Is Todd doing that mod himself?

Funny you bring this up...I called Ron Davis Racing earlier today and asked about 928 radiators.....turns out they make them and already have the molds..... $771 for a no cooler and 856 for an oil cooler..didn't ask about oil and trans cooler

 

On a full race car I'd think about measuring the hole and going to a big junk yard. Look over the stock and find a good 3- or 4-core model that'll fit. Probably some GM piece and you'll be able to find a new one for $200.

Us 928 guys get so used to exorbitant prices. $771 is reasonable?

Check this one:

All aluminum and $130. Took me 15 seconds to find one. Yes, inlet and outlet on wrong sides, but you get the point.

 

Yes, he has templates for making more.

He has done a couple customer cars, I have a radiator de-side tanked ready to be modified this winter.

 

Ron Davis used to make "928" rads for DEVEK they have zero warranty as I recall ......

 

How about the C&R rad from 928 International?

 

For a race car I would buy a big aluminum piece from Summit and fab up brackets. It will have more capacity and cost half as much than anything 928 specific.

 

I am in the process of having one built today. It will be finished this week. It will be brass tanks, copper/brass core, larger (5/8")tubes and they will use my aluminum oil cooling tanks. I am told it will have a better cooling capacity which I hope will absorb the auto trans heat that I believe causes stress on cooling system. I will post pictures and exactly what the specs are. This is my first attempt so I could be off! The shop tells me they build them all the time for hot rods and they are going with the same design and materials. The cost is $550.00-$600.00 depending on the tube size that fits.

+1 on Sterling's advice- the C&R has been reliable and has more capacity than the stock rad...

Yes, that is what went wrong with mine. They tried to repair but said it is something with the aluminum quality, that it was poor for the epoxy to adhere to a second time around.

Get in touch with Griffin Radiator in Piedmont SC (just off I-85 near Greenville).
They provide aluminum radiators from street to NASCAR. They are very helpful and can provide some modifications for custom fitting. They are about 1.5 hour drive from you. I am running the 55241-X model.
