Is anyone using a Mark VIII Fan to cool your car?
 

Hello:

I live in the Dallas area, it is usually hot and humid.

I am having a tough time keeping the 400 sbc cool driving around and in traffic.

This I know:

- Water Pump is in good shape and working.
- Duel fans are working and the air coming off them in hot (They appear to be pulling hot air through the radiator)
- I have a big Aluminum Radiator on it
- I have a a/c condenser in front, but the engine gets hot, off or on. (Vintage Air)
- The thermostat does work and is a 180 degree
- There is no obstruction in front of the radiator other than the grill. (69 Camaro)
- The radiator is full and have added a "Wetter".
- I checked and replaced the Temp gauge
- Replaced fan controller
- Has High Output Duel electric fans, 11 inch. (Since the car is at a different location, can't remember which type)

What am I missing?

I have been researching on google and their have been a number of people recommending the Big Fan off a Lincoln Mark VIII. (Part-RF64)

Here is a ebay search for the fans.

This is a bit frustrating, but I know there is a logical explanation for this. Can you all shed some light on this subject?

I have not been driving the car hard at all, and even cruising at 40 mph, the car will try to get hot.

Thoughts?

Thanks in advance.

my brothe has one on a 69 camaro

406 sbc

he bought a controller from the guy too

works like a champ

we were worried about it being too much current draw but it seems to be fine

let me tell you those things suck (in a good way)

dual 11's will not cool anything over 500hp, and I bet your over 500 hp. I woul dlook into the mark vIII fan, or look into ron davis's rad's as they are hands down the best out there, be cool is high priced and junk in my book.
Also get a 160 thermostat in the engine.

I ran the Mark VIII fan on my Procharged 540, wouldn't break 190 degrees idling with the air on in 100+ temps. I also used it on my friends 700 rwhp small block, same results. It flat out works.

Remember you'll need a 60-75 amp relay to run that, the 30 amp Bosch standard relay won't work. If you can afford it the DC controller for the fan is a very nice setup.

If you can get one I agree, that DCC is a great piece. I love mine.

+1 on the DCC and Mark VIII great setup!

+1 MINE WORKS GREAT

I'm running a MK8 fan and love it to pieces. It's on a 306 Ford with a Votech supercharger. I run around 450 to the wheels. The radiator is a summit 1 inch single core for a Mustang app. Never gets above the 'N' on normal. If anything, it runs too cool.

I concur with the relay issue. Get a 60 amp. Make sure to use the best 10gauge wire and keep the relay close to the fan. That sucker draws some serious power on start-up. I just used a Painless Wiring 190 degree 'on' sensor and it works great.

Are the Mark VIII fans pushers or pullers? Thanks

pullers.
