Electric fan setups

[Plex]

Pontiac Fiero electric fans bolt up perfectly... althought I dunno if you guys have those cars over there in Europe....

Plex, we have them here, still have to find one myself, they are a perfect fit on an RX7 aswell

Kristian, I think you're overdoing it on the cooling mate. NoHachi got a really good point. When the car needs cooling the thermostat will be open anyways, it is only closed during warmup. Removing it only makes your car take longer to get to good working conditions. You might be better off finding a thermostat that opens a few degrees 'earlier' if you are worried about your car heating up to quickly for the thermostat to respond.

The dual fan setup I can imagine as you do alot of lowspeed driving so you dont have 'driving' wind to cool your engine. But basically the fans only do their work when you're car is standing still or moving at low speeds. At higher speeds driving wind is more then what your fans pump around anyways.

He turns them on and off from inside the. That way he doesnt have that problem

Whow, hold on for a minute, we are mixing up 2 things here.

Thermostat is that little metal plate inside of your coolent passage that regulates whether coolent circulates within the engine only or is actually send to the radiator. When the engine is cold there is no flow of coolent through your radiator only inside your engine.

Thermoswitch is the little sensor inside your coolent plumbing that regulates whether the fans switch on or off depending on temparature.

If Kristian removed the thermoswitch that is sortof okay although you have to realize that the temparature meter on your dash is hardly accurate enough to switch your fans on and off at the right time so I would advise against that.

nice electric fan guide for ae86

2 plex: tnx god we don't have pontiac fiero's in EU.

NoHachi my man;

When i drive my car i always let it stay on neutral for al least 3-5 minutes.

&.... 5-8 minutes calm driving get the engine onto working temperature.

At this point the enginge oil is still not warm enough in order to puch hard.

engine oil akes about 20-25 minutes to heat up.
I always have the fans switched off untill the engine reaches about 75% on the temp-guage. then i swith tem on.

I have a special mixture of 92/AE86 waterpump - without the housing for the thermostat... Anyways - no real racecar has an thermostat attached & my car tends to over heat quite easily.

But i´ll soon attach an potensiometer which will direct the fans to the right speed.

I like my engine´s running cold . below 85 degrees.

Mux: true.. a lot of slow driving without wind-cooling - therefor the fans are connected as follows...
front fan - puches air through radiator - rear fan suchs air from radiator.

Kristian. Even real racecars have thermostats, honest i've built one and been around several ones. The thermostat is there for a reason. The engine heats up MUCH faster so the oil heats up faster too. This protects you engine from wear and helps build up a oil film on bearing surfaces and the cyl.wall.
There are plenty thermostats out there that have enough capacity to flow the amount you want. To be honest..a cooling system doesn't flow that much at all. If you're woried about that just take one from a bigger car.

[KristianAE86]

NiHachi.. i cannot agree with you on this...

not all racecars have themostat..

anyways....

My car tends to run hot when i drive....
this is part the reason i run this setup.

.. anyways.. i like it like this & it works for me

An example of electric fan setup:

Kristian,

Mayby your car is heating up becourse the water is flowing fast enught(can´t spell that)

Have you read the book by Graham Bell "Fourstroke performance tuning".

Hi stats that there are alot of car that can head up to much ,if driving without a thermostat,becourse of the flow speed.
