What are the pros and cons...
of removing the fan shroud? Besides weight reduction (pro) and Safety (com) are there any benifits or worries of removing this for more space?

dont remove it, i heard it won't lower your intake temps, it'll only raise them... thats if your running the stock fan, there are no pro's.

the shroud is the only thing directing the air flow created by the clutch fan.... do not remove it. Weight loss will be negligible anyway. Go with an electric fan if you want to get more room in the engine bay.

Also, if you don't want to spend too much on an e-fan conversion, ford taurus and escort both have fans that are about the same size as the fc's radiator, IIRC. That way you can just get one from a junked one somewhere, wire it yourself and save a bunch.

That I dont know... I know several people on the boards use them but that's about it. I guess any used part should be checked out first. They probably arent as good as aftermarket either, they were just for stock cars. I'll probably be using a ford e-fan on my car (whenever I get it to run).

No matter what though... RIG IT TO A THEMOSWITCH... do it like the factory would, and have it come on at a certain temperature.

yea i was procrastinating on my piping for my fmic and had my shroud off and the needle would be slightly above the middle but the other day i finally got a chance to put it back on and now the needle stays below the middle . so if youre doing the piping thats cool but dont run it like that... that waqs stupid of me and only put wear on my engine. also the weight you lose is ridiculous to even think about for that u take out your jack or spare or ?.

A good weight loss program (unless you want to take Friends in the car) is to remove all the seats including the driver. replace the driver seat with a street racing seat like a Recaro or which ever you like. good racing seats way less. so, you'll have shed some weight. and also if you want to( i don't know if this will have any impact on the rx7 depending on year) you can replace the rear hatch window. my Friend did that in his Z car and took a chunk out of its weight

rear hatch of our cars are alot, replace with some good lexan, hmm maybe a lexan front window. take out all carpet, kiss big speakers good bye, no a/c, air pump, you can keep power steering if you want depending on type of racing. Light wheels, replace sunroof with CF sunroof, CF hood.....there is alot you can do, removing the fan shroud does basically nothing for weight loss.

Ok because i'm considering putting one in. I have an 86 NA. I'm removing that massive A/C condencer. will it say on the fan the CFM? I'll be getting my trust tape measure and head to my local u wrench it (pick and pull is such a gay name) here shortly.

An e- fan will weigh more than a 2lb fan shroud also so thats not really weight reduction. But i understand what your saying with the IC piping so i guess your not worried about the weight.

A friend of mine recommended the Ford Taurus e-fan to me. He said it matched the dimensions of our radiator just right. And also said that it moves 4,000cfm I think?? Er, I think he said it had 2 speeds it'd run... I think one was 3,600 and the other was 4,000, but it's been a long while and I don't remember it so much.
Only big pro in removing the shroud is if you remove the clutch fan with it.... frees up space. And takes some load off the motor. Then the alternator takes that load back to power the e-fan... so... But you also won't have your e-fan running while you drive unless you wire it to be on all the time (bad).

i have the efan of a 93 ford escort. It is about the same size as the fc rad. and does a nice job at cooling. I wasn't aware of this fan have anymore that 1 speed but hey i learn thing ever day. Now i just got to find the low med hi switch that gm put on the fan for us fc guys.Joking) but ya the fan works good. I have it running as soon as the car turns on and from what i hear isn't the best but it still works. I really need to find out how and where to mount a thermoswitch.

One, you don't need the fan on all time. It is only required when sitting stationary or driving slowly. At cruise, a spinning fan is just an unnecessary load on the electrical system. Which brings us to point number two; the fan loads an already factory-overloaded electrical system. The factory 2nd gen alternator is either rated at 70A ('86-'88) or 90A ('89-'92). These ratings are optimistic, and actual output is somewhat less. Adding a constant 10A draw on this system is quite a bit of stress. Finally, you may actually overcool the car at idle, causing the thermostat to close. Not only does this increase fuel consumption, foul spark plugs and foul the O2 sensor, but it may cause a "heat spike" should you start moving under high load. The engine will heat up in the lag time it takes the thermostat to come open.
