Default Anyone with electric fan?

Didn't find much here on electric fan conversion. Anyone had any sucess with a puller setup? I know they are more efficient than pushers, but I will have room for a pusher by swapping it out with the heat exchanger when I do the killer chiller. KC and bigger ic pump is for sure but would love some feedback on fans because if I dont do it now, I probably never will.

Are you talking about something like this?

Sorry am not familiar with the benefits of fitting such a thing, would you care to enlighten me?

Yes a kit like that. Fortunately there are much less expensive options out there. Advantages are a thermostat and/or switch allows you to turn fan on and off at desired temps, lighter than mechanical setup, saves space, looks cooler, less water pump bearing stress, and more hp/tq. Hp gain is from the crank not having to work as hard. Its been dyno proven at around a 5 hp gain.

Do you think a 5 bhp gain would be significant or noticeable? I can see that it wouldn't be the primary reason for installing an electric fan, but TBH I can't see it being much of a positive benefit either.

Barnsie agreed, I'd not feel 5bhp increase on a 510 V8, so to my way of thinking hardly worthwhile spending the money, surely you'd get more from higher octane fuel?
