See above.

dnstommy...The only modification to the fan itself is you might have to cut down the depth of the shroud depending on your setup. I had to trim mine to clear the waterpump on my last car because I couldn't offset it enough. Depending on how you choose to mount it to the radiator, there might be some bracket fabbing. I just used the little radiator zip tie gizmos to mount mine.

The biggie is the wiring. The fan draws some amps...especially at startup so you need to wire up with some good sized wire and 75 amp relays. Monte Smith says to use 10 gauge wires but I have burned down some 10 guage with that fan. I've got mine wired up with 8 gauge. If that gets toasty, I'm going with welding cable next time.

 

I'll have to look into it for the next car. I am happy for the coupe with the Black Magic. Even on the street it keeps me cool. But I don need to slow down my water pump. Anyone know how to build or buy a voltage regulator for 12-16 volt systems. I would like to bring my pump down to 9 volts to slow how fast it flows the water. If not I am just going to reduce the size of my hoses.

 

I am not worried about the price, I want to get it right the first time. I was about to get the Be cool dual fan and alum radiator setup that goes for like a grand.
