PWR Aluminum Radiator
What about this radiator??PWR Aaluminum Radiator..I think the price is about 430$.Here is a link: http://www.pwr-performance.com/mazda.htm
I don't know a lot but an almost double sized radiator can pass more air in the motor so better performance...Good gains i believe...
What do u think??Is there any1 who has changed his stock radiator???Can u give me some info?

Hey bureau13, how much heavier is the PWR radiator compared to stock? I heard that is about 3lbs heavier. is that so? I just want to make sure that its not like 20lbs heavier than stock. 
Thanx
Thanx

You know, I never compared them directly, but it wasn't very heavy. The thing is all aluminum (at least the one I had was). It had a thicker core, but was a two-row just like stock, and it had aluminum end tanks instead of plastic. It wasn't anywhere near 20 lbs heavier, I'm sure of that.

I remember talking to Huff about the PWR radiator. It's a really nice piece. I don't know what kind of gain I would expect in stock form. I'm waiting for Koyo to come out with a radiator for the RX-8. I think they have an American subsidiary, which means it'll be easier to get my hands on one.

doesnt having a better radiator mean better cooling and a ...longer lasting engine...?...........cuz if it is i wouldnt mind doing anything to keep the engine long as possible since rotories have a problem seeing 100kmiles

Wouldn't it be prudent to change out the thermostat to a lower temp. thermostat when you change out the larger radiator? If the larger radiator cools the collant too much wouldn't that cause it to be stuck in recirculation mode all the time.

You don't always have to get a larger radiator, maybe just one that is more efficient, though the surface area of the former will dissipate heat better. Radiators are heat exchangers, so they should follow the same principles of aftercoolers.

I think I'm a little confused as well. Oh well, we'll be educated soon enough.

It does not.
No point in a new radiator.. Theres a point where too cool of an eng can start to lose power...

How often does your 8 run cold? Maybe it's just because I'm in the effing desert, but mine's pretty much consistantly running warmer than I'd like it to be.
Especially June-Sept.. I don't see a more effecient radiator, here and for me, at least, as a bad thing

It doesn't make a difference if it is on a turbo-supercharged engine, or on a mechanically-supercharged engine.
The term intercooler was coined in the aero industry, as they had multi-stage supercharger compressors, and they ran the heated up air coming out of one stage through a cooler, before it went into the second compressor. Therefore, it was "inter" cooled - i.e. intermediate cooling between compressor stages.
With time, the term intercooler has taken on what we now see - a device that cools the charge after it has been compressed, before it enters the engine.
So - an aftercooler and an intercooler are really the same thing.
All of this has nothing to do with the radiator in question, as this is a device for removing heat from the engine's cooling water. A bigger one won't give you more power just cause it flows more air. And if it is too good, the thermostat will close off, ensuring then engine does get up to the correct temperature.
BTW - The PWR radiators are made here in Australia

hmm this might be a stupid question, how come supercharged cars use smaller intercoolers than turbocharged ones? I've seen a hks supercharged 350z the intercooler is like 1/3 of the size of other ones.
