86.5 supra cooling help.

The shroud has a place for 2 fans.

With the shroud in place the stock fan is excellent at it's job.

Too many novices have tried converting without really knowing what they were doing leaving themselves with burned up wiring, fried batteries and engine bay fires. No way I'm going to recommend you try.

Besides, the losses caused by the stock fan can be thoroughly reduced by ensuring that your fan clutch is working and the oil in it is fresh and swapping the fan itself for a flexible aluminum fan.

Ok, I didn't realize that before, thanks for the info. My car didn't have the electrical fan for the AC so I would only need a shroud for the engine fan.

How many blades should I look for in a aluminum flex fan? Thanks.

The more blades it has the more effective it will be.

Something I forgot to mention is that most aftermarket aluminum fans require a specific fan clutch and no, the stock one won't do... it moves too fast.

I recall talking with someone on SM about the 7 blade Flex-a-lite fans... I think someone added that they were using one too and it worked well. I can't remember all the specifics, but that fan requires you use a different fan clutch and a small spacer.

Thanks for in info, I'll look in to it.

Personally, I would upgrade the radiator and thoroughly flush the coolant system before switching fans. The stock fan does an excellent job when allowed and I'd bet it moves more air... it just happens to be a bit heavier and louder.
