Electric Fans, can they replace my clutch fan?

What did you use to mount it or how did you mount it?

Do you have the fan dimensions?

Also does the fan call for such a big relay?

Here is the amperage spec's - Amperage High-17.5, Low-11.2

The Spal relay kit handles up to 40 amps: https://www.summitracing.com/parts/spu-ix-185fh

Lastly, what manages the 2 speeds and dictates when the speeds are changed?

Thank you.
The fan pulls over 70 amps at start up and the 40 amp relays will fail over time. You can get 70 amp relays but cost more. Dakota digital and flex a light make 2 speed controllers that will handle the load but cost $140. I went with the starter for cost. I currently just use high speed as I don't have A/C yet with toggle switch I will run it through a temp probe this weekend. As far as mounting I used aluminum angle to mout to radiator I had to cut mounting brackets off cause my inlet and outlet on rad are on opposite sides I will take pics this weekend.
