hey guys im actually considering getting the j's racing fan switch to get the engine running a little cooler but is it actually healthy for a mostly stock engine to run at those temperatures? i would understand in a high compression motor or a FI since the temperatures would be higher. is there any actually whp gain or is just so the engine can run smoother and cooler?

 

colder makes more power, I think most would suggest you do thermostat and radiator cap all at the same time though.

 

yeah i know colder is more power but i was just wondering when does it become TOO cold, it could be a problem, but i dont think j's racing would make a product like that.

 

Its 15 degrees colder according to aj's website. I say go for it, I'm going to get it along with a thermostat and some colder plugs right before I get my new tune.
