I found this link off a post from another forum member (forgot who it was, sorry), and the radiators are pretty cheap compared to other brands. My question is does anyone have these radiators? If so, any fitment issues? And is it as effective as say a koyo or fluidyne radiator? Thanks.

sup artin its mike

dude ur better of gettin a koyo

It's not something you want to compromise with on an FD. Really, Koyos are damn cheap for what you get.

 

koyo is what i have but, I've heard that the brand does not matter when it comes to a radiator. As long as you do not have fitment prob. and the core is much bigger, then it is effective.

Hey wats up man.
I'd really like to get a koyo but ive heard too many things about fitment issues. Also Mahjik i was referring to the all aluminum ones. If these fit well and work efficiently (which is what im trying to find out), why not get em?

"This is an ALL ALUMINUM RACING RADIATOR that will exceed the manufactures specifications. It is a wide 2 row core. It is a super high performance, with substantially higher efficiency cooling core designed for more demanding racing applications."

I would imagine they are the same aside from the materials (copper, brass, and alum).

Most people here are afraid to try anything that "doesn't have a brand name" on it as then they wouldn't be able to list it proudly in their mod list.

 

I'm thinkin' about doing the no name two row aluminum one; I'll let everyone know about it afterwards. I can assure everyone that Koyo and Fluidyne are not the only people in the world who know how to assemble a radiator

 

Same here Damon. I'm thinking of doing one of these and slapping some black paint all over it (yea, I want to see if that old wise tale works ).

I'm contemplating placing the order right now.

 

Why would you want to paint it black?

 

The myth is that the black paint helps it to not absorb so much heat. Whether it works or not, who knows:

i c, so do you guys recommend that i buy it?

 

Doesn't black absorb heat better than silver? Pretty sure it does...

As for brand names - like, I said, koyo is pretty damn cheap in the world of performance radiators (half the price of big brand names). Why trust something so important to something untried. Though I don't doubt that a significant number of people do shy away from 'no names' for the reason above

 

If there's one thing I am sure of it's that the conventional wisdom of the masses around here can be way off base...

 

i personally don't care what name is on something but if no one else has tried it, i'm not sure that i would be willing to do it first with my baby. sorry guys, but i can't afford to fix what might break. i am looking forward to hearing if that black paint helps at all

 

Untried? People have these radiators (and have had for years). Did you not read the first link I provided in this thread?

If we never try anything else, how is anything ever "tried" and/or "proven"? I, like Damon, feel that it's not rocket science on how to assemble a radiator. I find it hard to believe that Koyo, Fluidyne and others are the only companies that know the "magic pixie dust" that goes into creating a radiator.

This is the same discussion as the whole "Autometer is crap" stuff. If you really believe that it takes a super brand name to make a certain product, go ahead and pay their premium price. However, more expensive doesn't always equal "better".

 

Wow, that's a good price on the aluminum radiator. I may have to think about that too. I'm getting ready to start working on replacing all my coolant hoses anyway.

 

a thin coat of black paint will increase the emissivity of the surface ... it will reject heat better with no airflow ... stopped with no fans going.

the hard core critical heat transfer is due to convection, with cross core air flow, and almost any coating will act as an insulator, and reduce heat transfer.

black is for show, bare aluminum is for function (check nascar/racing rads).

 

A product that has been continually, and successfully, used by owners of a specific vehicle, in my mind, is a worthy product.

A product that someone is willing to take a risk on, is just that - somewhat of an unknown. Could well be a better product - for sure. If we were talking about another car, it would definitely be an easier decision.

I agree, it's not rocket science at all. But I think most people are inclined to purchase something that has some element of trust built up around it.

In the scenario where I'm looking at three radiators - (a) is the koyo - relatively cheap, an accepted standard with FDs, I know it's going to work. Price is $XX (b) is a 'name' brand (and, let's face it, probably a product that has been made by someone like koyo, then 'rebadged'). It's used by some of the top japanese workshops. I know it's going to work. Price is $XXX (c) Is the 'no name' brand. I heard someone used it and it was okay. It looks like it might fit. On a superficial inspection, the quality and materials don't appear to be as good. Probably might work... Price is $X


That's not a difficult equation for me. Particularly given the requirements and issues of the FD.
