AWR: $558.95
http://www.awrracing.com/store/produ...products_id=68
this is the same radiator mazda motorsports sells to racers, but AWR's price is better.

theres a mazdaspeed radiator and r magic radiators, not sure if it's worth looking into especially for double the price...

It will not lower the temp much. Its just going hold your Coolant temp. at a stable level Longer than stock Radiators.
a Must for people who "SC/Turbo/autoX/Race/drive HARD on streets with hot temp"

I have fitted a PWR radiator to ny RX-8. Nice quality but the mechanic said he had major problems with the mounting brackets. It appears that they do not match the stock radiators brackets. The mechanic had to make extra bracketing to fit the PWR radiator. I dont know if this is because euro zone cars differ to those in USA?

And how to get extra cooling for the oil
Dear sirs,
We easily find aftermarket radiators to cool the engine coolant (water+glycol or any other antifreezer. Let´s call that just water). Some examples are shown within this thread.
Now, if you get more engine power you need extra water heat rejection (i.e bigger water radiator) AND also extra oil heat rejection. Probably in the same proportion if not more.
Therefore this thread would be comprehensive if aftermarket oil heat radiators are added to upgrade the stock ones (some models are equipped with one whereas some others with two BTW).
Anyone knows of any oil rad?
Cheers

Note: It is sad to realise the complete lack of thermal data on aftermarket radiators, such us heat rejection, max air temp, water outlet temp, etc. It is pure marketing to quote a radiator as "racing radiator" because how better is that?

, hope somebody from PWR reads this. Don't know why they can't get the mounting brackets right. The PWR is a lot more expensive than the Koyo, so no excuses

Pulleys
Changing to competition drive and water pump pulleys will significantly reduce, if not eliminate, water pump cavitation. Water pump cavitation on a rotary engine (with stock pulleys) is unavoidable at rpms above 6500-7000 and is a significant contributor to engine overheating. Cavitation is defined as a disruption of the water/coolant flow through the water pump. It is created when the water pump impeller spins at such a high speed that it is actually churning instead of pushing the coolant through the pump. Changing to a larger water pump pulley and a smaller drive pulley, allows the water pump to spin at lower rpms, effectively transporting the fluid through the pump.

holy crap! Wow I thought getting the underdrive pulley was just to look for some small gains... You guys are saying that it allows the water pump to run better at higher rpms?
Why didn't Mazda do this from the start?

It is pretty warm while at idle w/ the pulley, while moving its frosty and delicious.
