VOTE!! Electric Vs. Belt driven fan and water pump

[2fit661ca]

Vote on which you prefer; 1 vote for the fan type, and 1 for the water pump type

The vehicle is a G-body with a Chevy 400 small block. Currently it has the stock 180 horse, but it is an ongoing project with no limit for the amount of horse it will eventually put out.

I just installed a Mark VIII electric fan on my Olds 350 Diesel two weeks ago. It is awesome. I get on the highway going 80mph. The fan will cut on at 185F and is powerful enough to cool the water temp to 170F (thats when my fan switch cut off) and I never slow down. It looks clean and doesnt rob power.

I voted belt driven water pump. Unless its a pure drag car. I would just keep the water pump belt driven.

Had the Mark VIII fan on my 350 SBC Malibu for nearly 3 months now driving in weekly and it's great, absolutely love it. At idle in front of my house for like 30 minutes, stayed at 190°. Driving it will drop and rise according to how cold it is outside. All depends on what you use to control it. I also agree on the belt driven pump. I went with a GM serpentine setup and wouldn't go back if someone gave me a pump for free.

x3 for electric fan and belt driven water pump

on a street/daily driven car i definatey believe a belt driven water pump and a electric fan would be best

I realize its trendy to put an electric fan on everything, but the load required to produce the amps has to come from a belt driven accessory in any case. For best of both worlds (air movement/ease of turning) a THERMASTATICALLY controlled clutch fan is the way to go.
If you are going to drive it on the street at all, the electric water pump is a bad idea. The only reason I would want one, would be if I was hot-lapping @ the drag strip and I wanted the pump running with the engine off while I was waiting to stage.

I agree 100%. One of the magazines did a shoot-out a few years ago comparing different brands of flex fans, OE fan, OE clutch-fan, and electric fan. All were adequate for normal cooling but the clutch-fan cost the least amount of power to run.

I have an 81 Buick Regal with a 400 bhp Chevy 350ci I run this as a Drag car with no street use. I have the Proform electic waterpump and a Pro Comp 16 S blade fan on a 20 inch Griffin Aluminum radiator with a 160 Thermistat. With this combo I rarley get the temp over 190 I leave the fan off til it hits 180 then it drops to 160 almost instantly.


On a hot day sittinging in the staging area temp never gets over the 190 burn out box with fan on temp 170 after 1/4 mile run temp is about 180 (12.88 et)

I don't know how good the waterpump would work on a street car but I love it on my drag car. you look under the hood and see no belts no pulleies just the clean waterpump and the harmanic balancer.


have fun

No alternator? How do you keep the voltage up on long night of racing?
