I always thought they were for show. Never thought they were for performance. It will be interesting what others with experience in these fans have to say. I will sit here and wait with you. LOL

I've used them street/strip cars. The advantage is that they weight less. The disadvantage is that they won't cool as well in some situations and if they dont move as much air as your oem fan, you could also lose some A/C performance.

Interesting. I thought they might offer a performance advantage since they essentially flatten out and offer very little resistance at high RPMs. Would you say that an electric fan is a better option, then?

An electric is better from a performance aspect because it reduces parasitic drag on the engine. The down side to electric is that it won't move as much air as an engine driven fan. As long as you don't encounter overheating issues, electric is a better choice IMO.

I totally agree with that. Dual electric fans will help a bit with overheating issues in high ambient temps. I have dual electric fans on my SRT8 and they work great!

They flatten out because they're pushing against the air. Beause of that they are worse hp suckers than clutch fans (at best a wash due to the lighter weight. They're nice for show cars and for 4x4s that plow through deep water. Otherwise they're useless.
