time for a replacement
 

Well it's time to replace the radiator.
I was wondering if it is necessary to upgrade to a competition type radiator.
Or if a stock replacement is sufficient. I'm not planning to do any major mods. Maybe intake/exhaust.

Any suggestions is appreciated.
Thanks

PFS uses stock radiators in thier race cars without a single overheat.

That is interesting. Thanks for the enlightenment.

Well, in a lot of cases, you HAVE to use the stock cooling system. Even an aluminum AST replacement would bump you up a class.

Look at the prices of the radiators. You can get a Koyo or Fluidyne for $425 or so. If I remember correctly, the OEM is quite a bit more than that. So obviously if you can get a better radiator for less money....

I've heard that rotorys like cool oil better then cool water. So bigger oil coolers might be better.

I went ahead and bought a stock replacement for $240.
It has a life time warranty. Better than 18 months for Fluidyne or Koyo.
I can spent the extra $$ on other upgrades. Like a water sprayer for IC. It gets pretty hot here in San Diego sitting in traffic. :mad:
