I've been wanting to put a Thermo fan set-up on my R33 for sometime now and was just wondering what people out there had already done an what works best?

Single or Twin?

What size fan/s?

How have you mounted it?

What sort of switch set-up has been used? thermo controlled or switch?

What brand stuff has been used?

what'd it cost?

feel free to post up pictures too, a picture says a thousand words!!

cheers

I have an R32 and have installed a 14" Davies Craig fan but prior to installing the 14" I had a cheap 14" and 10" fan I purchased from ebay. Unfortunately I dropped the 14" fan when installing the 10" and subsequently damaged the motor bearings. I replaced the fan with a Davies Craig 14" fan (In my experience Davies Craig fans are reliable and good performers).

I have retained the 10" and the factory A/C fan. All 3 fans are operated at the same time; result = very effective.

The fans were triggered via a temperature switch in the bottom of the radiator but now by the Haltech ECU which now runs the engine. I recently installed a single 14" Davies Craig fan on my Bro-in-laws R32 and it operates with the A/C fan.

I managed to purchase a 14" Davies Craig Fan kit (includes bolts, relay and wiring loom) from a local Automotive A/C company (Brisbane) for $165 (inc GST). I then purchased a new temperature switch for $45 from Autobahn. The switch activates at 85 degrees and turns off at 80 degrees (Autobahn didn't have a switch in stock that would switch on at about 87 and switch off at about 83). Keep in mind the thermostat opens at about 76.6 degrees.

Total price is around $210.

We fitted an N14 Pulsar twin setup to an R33 and used the aftermarket ECU to switch it.370rwhp with no problems.

The Fan on the passanger side needed to be unbolted from its mount and refitted to the same bolt holes but moved to the front of its mount to make more room for the power steer pump.

I run 2x12" Davies Craig Thermo's on the front of my radiator and no clutch fan. i have a radiator industries alloy radiator.

they cool really well, and actually on the highway gets too cold! be interesting to see what its like with cooler in front of it

    • I swear at my GKTech ones every time I have to take them apart and replace a spherical. But I wouldn't swap them for anything else. They absolutely slay every other option, at least in terms of how they actually work. You sure you don't want to live with bearings? I mean, they don't have "ball bearings". They are rod ends and sphericals throughout. Tough as nuts, even though I have found more than one way to wear them out.
    • From when I was looking at getting the 86 engineered for the turbo, the joint said to put in a few euro 5 or 6 cats, then tune the car on a nice clean E85 tune When I was looking at a turbo for the MX5, it was basically the same thing, a couple of cats and a nice clean tune Although, it will depend on the year of the Jeep IRT emmisions standards required, and what mods are done, especially if it has a newer engine installed that requires a higher Euro
    • Yeah - but it's not actually that easy. There are limits for HC, CO, NOx and particulates. Particulates shouldn't be a concern in any petrol engine unless trying to comply to the very latest Euro standard. But getting a tune right so that all the others stay within limits AT THE SAME TIME is not a trivial exercise. You couldn't possibly get it right by just guessing at the tuner's dyno, unless he had a 4 gas analyser up the pipe, which is not often the case these days. It used to be. Every decent shop that did "tune ups" (as opposed to tuning) would have a 4 gas analsyer. Perhaps there's still quite a few of them around these days. But most "tuners" are only watching O2 and power readings.
    • Slight segway but the most expensive part of the whole thing which I would have thought would only be required for an engine size/type swap, not a VIV test, is emissions testing.  That's when you get into the big bucks.  I can't remember the exact price now but I got quotes for the GT-R based on swapping to RB30 (not that anyone bothers doing it legally anymore...) and it was around $4500 just for that alone.  The guy that does them manipulates the tune on the vehicle to make sure it passes.  The cheaper option is to book into Kangan Batman Tafe (I think that's where it was) and hire their tester.  Allegedly you're not allowed in there with the car though so not in a position to tweak anything to make sure the vehicle passes.  I'm sure in this day and age of ultra tuneable ECU's you could get the tuner to program a special efficiency (clean) tune that emits the lowest amount of particulates possible that would pass the test.  It might only make 50kW's but as long as it passed who cares!
    • I'm sure he has left signs, or, he is looking down, laughing That's my cunning plan for when I leave, lots of half finished projects, with no rhyme or reason of where I was actually up to, just to keep everyone on their toes
