However its both your cars so I dont know. I switched to an electric fan immediately because higher rpms constantly on track would be more likely to destroy a stock fan anyway.
I do notice the noise when my mechanical fan switches on but I haven't really noticed a loss in power. I've seen what they look like when they grenade and its not pretty though. I'll probably switch mine over this summer when I do a whole pile of preventative stuff.
