I know this is off topic, but has anybody ever researched putting a puller fan on the back of and intercooler.
Supra mk3 electric cooling fan

Yeah, its done in weird setups like MR-2s where they dont have much air flow at all. With an FR car like ours with plenty of room for a big ol front mount, I dont think it'll do much; unless you are in stop and go traffic, in which case you wont need it anyways.

If I had to put money on it, I'd say the mechanical, with a properly working clutch and fan shroud pulls more air in the upper rpm band. But that's just a guess.
Just did some googling, because now I'm really interested...found this:

Now it's specifically for RX-7's, but there's some really great info in there on how much the stock mechanical fan pulls (calculated out), how important the fan shroud really is, etc.

Many people have learned this the hard way not running a thermostat on the road course. Sometimes the water doesn't stay in the rad long enough to cool down.

You're smarter than me....just some clarification: it would really cycle through the radiator too fast to cool down? I never ever would've thought about that...
Yes, Moroso even sell a kit of restrictors to run if you remove the T-Stat so you can "tune" the operating temps.
I wish I had enough room to install the factory fan setup.....
I had no choice but to put in e-fans
now I constantly worry that they will fail.

No shit, I never would've thought. I'll read up on those restrictors too and how they work.

You could always splice into the power wire going to the fans and run it to an led mounted somewhere on the dashboard. It wouldn't help if the fan motors blew, but that's the least likely scenario anyways.
I prefer 2 smaller fans over one large one simply for the fact if you wire them individually and one fails you can still limp the car home.

Right. It's called residence time and is also important for airflow across a heat exchanger...

Wire them right and the odds are they won't. That said there are lots of simple ways to sooth your nerves. For example you can monitor fan current or speed or use a temp alarm. I use the stock fan and still have an alarm. Very easy to do using the stock AC overtemp switch...
I have an electric fan on 1 of my N/As , But Im gonna keep my clutch fan on my GTE as it moves hella air with a good shroud ..

I just have them hooked up with a thermostatic controller.... sooo none of the stuff you mentioned.
Any suggestions, or well, more in-depth suggestions?
First, it'd be better to monitor the fans rather than temperature because temp actually needs to climb before you'll get an alarm.
Using the stock AC over temp switch (Water Switch # 2 iirc) is simple. You tap the line where it comes in through the firewall and connect to one terminal of the alarm device you want to use. A Mallory Sonalert or similar piezoelectric sounder works well. Connect the other terminal to a source of switched power, e.g. power when the key is on. Ty wrap the sounder up under the dash or throw it in the glove box and you're done. You will now get an alarm whenever coolant temp exceeds 235 F, a value too low to cause any damage and one that shouldn't occur unless there is a problem...

No problem. Someday when you hit it big get one of these:

Aviation engine analyzer. Monitors and graphically displays everything from oil pressure to individual cylinder EGTs. Programmable alarms, data logging, voice prompts, you name it. I actually know someone who has this in a car. Way overkill but pretty cool nonetheless. Not cheap though...

In the case of the 77 celica could you run a fan with out the fan clutch. I guess I really dont get the purpose of the fan clutch I don't remember older V8's with them could you run with out the clutch assembly and if so would it work? Wait... Would it work in a safe and stable manner?
