Is it practical to run electric fans on a street car? I currently am running a FB 400 Conv. bored .030 with a mild Comp cam, RAIII Long Branch exhaust, stock QJ, and Mallory Unilite. I runs 185-200 degrees, the high side usually at sustained speeds above 50 MPH. My plan is to go with a RR radiator, but would like to free up a few more ponies thru the use of electric fans. Is this feasible or is my present setup (flex fan/shroud) the only practical way to cool this thing down?
Maybe Studebaker can comment.... Robby D

Would you be able to post photo's of your Mark VIII electric fan set-up? |

Please don't get your 12volts from the battery terminal with this fan. Run a wire from the alternator to the fan.

I was going to run the wire into the car and run my electric 16" fan off one of the empty spots in my fuse panel, is that okay to do?
hey goathead....do you have any more pics from your engine bay? That looks pretty freakin good and would like to see more.

53,
Can you still use your stock shroud on a 70s T/A? I never even considered installing a fan/s on the engine side. You mean you can toss the stock fan and clutch or do you retain them for more airflow? |

That looks really good Danny.
Good Job Studebaker! Nice parts! Tom V.

The dual system is $395. It is laser cut and polished, and includes the thermal switch.

Goathead,
What kind of electric fans are those? Where did you get them and how much? Could I get a similar setup for my 66 GTO? That setup looks so sweet with the Rodney Red. What temp you usually run at with that setup? What thermostat you use? 180? Thanks! [email protected]

My (7.50 1/8 mile).street car(79 ta) has a mark 8 electric fan. I install it for performance use, havn't went back to the track yet.
But it keeps my 455 cool in traffic jams 95 degrees outside. One thing I didn't like was buying a 104 amp alternater and 1000 cranking amp battery. |

I've modified a pair of 97 TA LT1 electric fans to fit my aluminum radiator. The darn thing stays at 190 and won't move any higher. I'm also using a thermal switch and relay setup made by hayden. If you look at the pics you can see the brackets and sensor fitting I had to weld in to accomodate the fans. I've posted some pics of the install here.

But your system probably won't fit my 71 T/A as there's the cross brace that runs vertical in the the front of the a/c condenser - right in the middle.

How did you physically attach the fan?You can buy a reasonably priced ($70) 135 amp alternator online from alterstart in dallas. Comes with a lifetime warranty. Several of my friends have used their stuff with good luck. You must upgrade your output wiring to handle the extra amps. This is the internally regulated one although they seem to have every other kind as well: http://www.4alterstart.com/pages/sto...putalternators their e-store: http://www.4alterstart.com/ |

Do you have a dual fan setup for a 67 GTO? If so do you have any instock and what is the lead time. Also, can you connect to battery power or does it have to be allt. connection? How does it sense when to turn off or does it just stay oon all the time?
Thanks Brad

Robby,
What year FB do you have? We make a dual or single fan system from laser cut fan shroud. THe stock system is almost always best, but there are many reasons one chooses to go electric. From what you describe, your radiator is just not efficent enough, so I think you will be fine with our radiator and electric fans. Heres a picture of our dual system. Thanks Jerry |

It should, our 75 is an AC car.
THe fans are on the engine side. |

I bought a '95 Ford Windstar dual electric fan set up in the local wrecking yard. With the exception on blowing one fuse and getting up to 212°F, I have not seen it above 187°F on the street in 95°F. I reached 202°F racing at the Grove at the T-N-T, but it came right back down.
I also upgraded to a 94 amp alternator. I run separate wires to each fan and each one has a separate 30 amp relay and 30 amp inline fuse. Use 10 ga. wire with a 30 amp circuit. I have a 170°F thermal fan switch that I got in a kit from Summit. The fan switch has 1/2" NPT threads and screws right into the head. I don't like the type of sensors that sense the air temperature at the radiator. I want to know what the water temperature in the motor is. Vance, I ran the hot leads directly from the battery to the relay, is this bad? [img]ftp://members.aol.com/gr8one68/gr8one68.jpg[/img]
