Ur probly gonna burn me for this...
hey.....i just wanted to let my fellow rx7 freaks about my e-fan. I'm a broke college student so i didnt want to buy one....so i've been on a quest for the perfect fan.
i own a 92 honda prelude si aws vtec as my winter beater. i was cruising in that the other day (it gets better gas milage than the 7) when i realized that it had a pretty kick ass fan. So i hooked it up to the rx and it has never run cooler (even when i drove it 1hr to my gf's college, and played around in a parking lot for about 30mins. ) I kno i'm going to be burned for putting a honda part on my mazda.....but i works great...so i'll take one for the team. |

Now, how can we properly ridicule you without pictures? Post Pics! |
BURN!!1
What was wrong with the stock fan? My coolant gauge never goes over 1/8th even when pushing it hard. |
dude as long as it works, but definitely PICS
|
pics will come on luch break (11:30 est) so i can be properly hated upon by all rx7 owners.
Stock fan runs off a belt............belt = loss of hp.....everyone whos anyone runs an e-fan.....thought it was my time....and i know that now the alternator is running harder and that runs off a belt......but it cant be as much as that stock fan.....and now it runs @ 1/4 on the gauge as opposed to the 1/2 that it was accostomed to. |

the loss of power from converting to a electric fan is not that much. cant even be felt...but i guess if you like small power gains...
|
Post pics.... is it any different from the Taurus e-fan install?

well.....here it is.....feel free to rip me a new one......but my mazda runs cooler thans urs....lol
|
this fan will seriously suck a plastic bag in from like 3 feet away...(tested)
|
oh....probly shoulda mentioned.....it does have a racing radiator in it....:dunno:

it adds up.....i raced a stocker NA and beat him by 2 cars |
At least loose the studs that are sticking out from the pulley. One less thing to catch on clothing, etc.

Your fan is no help when you're pushing it hard. Regardless, the stock fan is fine in 99% of applications. However, an e-fan clears up space and, to some people, looks better.
|
is it wired up to run all the time?
A temp sensor to turn it on and off i imagine would be helpful. Isn't the engine supposed to run in the middle of the temp gauge? Isn't there an optimal running temperature? Otherwise I like it. Doesn't look to bad either |
The engine is designed to use the fan/clutch combo. What a waste of effort for no pay off. Also E fans work intermittently while the standard is always kinda moving. I guess if i was broke I'd do anything I could too.

It could also be attributed to engine compression/liveliness... Your added 1/2 hp from taking off the fan is offset by the suspension modifications (strut bars) you've put in. :crzyeye:
remember the other kids is 100% stock - mine completely gutted Intake header-back straight exhaust.....need a header. No AC or anything unnessesary Lightweight rims 245 55 16 Lightwieght Drive axle Stage 2 clutch Solid tranny and diffmounts.......theres more. theres a reason i beat the kid.....i didnt say i just did a quick fan job and beat him by 2 cars his car has 66,000 miles.....mine has 89,xxx |
the way i see it is;
If it works better.....do it |

You know the driver makes a difference. if you dyno with and without stock fan you'll be like hmm...not that much. I personally like the electric fans...I wouldnt put one in unless it was a nice one though... |
do a streetport..you will see a gain :)
|
OP, the studs just screw out - just put two nuts on each stud, lock them together and turn the one closer to the pulley. Regular thread.
|
thanks to the search button, i found out someone else has a prelude fan lol
i'm getting one for free =D but i can always wait for the 87 fiero GT to wreck that my friend just got for its fan |
edit : wow this thread is old..
|
i don't know why the guy was so concerned about getting ripped for using a honda fan, we all use different stuff, i have a fiero fan, others perfer the tauraus fan.. anyone know how many CFM's this prelude fan is? i know my fiero fan is 2500..
|
at least get a shrowd.. damn. that fan missing over half of the damn fins
|
wired on all the time is not the way to run an electric fan. coolant will never get to normal operating temps :(

The coolant will reach whatever temp the thermostat tells it to. The problem with a "always-on" efan install is that it's terribly inefficient since instead of working in concert, the different components are essentially fighting each other. In a perfect world, you want the thermostat open as wide and often as possible and the fan off as much as possible. Running the fan all the time means the thermostat is always competing with the radiator to keep the coolant at operating temp. A properly set up efan install is infinitely superior to a mechanical fan, but an always on setup is actually worse. Either do it right or don't do it at all. |
Also, your theory is flawed that t will increase hp. the stock fan doesnt spin all the time.
how much energy does it take to move the stock fan? when you hook up an electrical fan, it runs through the alternator that has to do more work now. more work means more resistence on it meaning the engine is using the same is not a lil more power to power the e-fan. plus your e-fan sucks. its too small, and it isnt covering up enough of the radiator. |

I just wired up an efan over the weekend, Taurus dual speed on a temp probe using Aaron Cakes write-up. My old manual fan always spinned, so it seems to warm up much quicker now. Couldn't be happier, and the extra engine bay room is quite nice.

my car would never pass 180 degrees at any point in time with the fans always on. cold nites it would stay at 175. it shouldve been at 190 ish from my understanding. it wasnt on a rx7 though.
A car, RX-7 or not, with a properly working thermostat, will run at thermostat temperature even if the fan runs all the time. This is the purpose of the thermostat. As a practical point of reference, my e-fan controller last summer was a bit confused and the fan ran at 100% all the time. The temperature according to my Microtech? 84 degrees, which is exactly the temperature stamped on the thermostat. |
sorry for resurrecting a 1 year old fan, i just did a random search and found out someone used a prelude fan lol
i'm just in direct possesion of one for free |
