New Cooling Fans

Designed to replace the factory plastic fan assembly this new high performance model offers quiet operation, excellent engine cooling and has features making it very efficient at high vehicle speeds or during competition events.
The unit incorporates a two speed curved blade fan providing high airflow from a single fan while dual sets of brushes allow the fan speed to change based on temperature as well as a/c loads. The eight black rectangular boxes are actually flaps. These are designed to be sucked shut under vacuum at low vehicle speed increasing airflow across the entire radiator core. At high vehicle speeds they open, reducing drag and allowing maximum airflow.
We designed the unit to fit both our high performance dual pass radiator (pictured) as well as a replacement for the OE fan unit on stock radiators.
Features:
  • 2-speed Bosch dual brushed high performance fan
  • 8 integrated flaps to allow increased airflow at high vehicle speed
  • Strong 6061 aluminum construction
  • Integrates into factory fan control system
  • Weighs 8.8lbs
Radiator not included but available!

Interesting .... What testing have you done to prove this flapper concept ?

I actually cannot take credit for the idea Brettus. I believe the first time I saw the concept was on either a VW Scricco or a Fiat Spyder many years ago. We just implemented multiple units here to provide more airflow at high vehicle speed.

Yeah they have those flaps on a Mazda 3 so it should work excellent on a RX-8. How many CFM is that fan rated at?

I don't need to see any testing. Your company's reputation is testing enough for me.

Sounds good to me, Scott. I look forward to receiving my unit. Anything we can do to beat the Texas heat

The flapper doors are a common mod on aftermarket shrouds. Especially when a high output fan that is relatively "closed" in profile is used.

It gives you more airflow when the vehicle is moving...and they close off when the fan is in operation...best of both worlds in my opinion


The big one in the picture is a Ron Davis custom setup...

The rx8 fan regime has the fans running constantly once the on temp is reached . They don't turn off at speed ................................

I think (but have not tested) the 'speed' parameter in the ecu is for the air con fan on setting.

I thought the fans turn off when you're moving fast. If that's the case, I'd love to know the exact speed they turn off at.

Lol, as I mentioned Shady they have been around for many, many years. We just implemented it here to help further improve high and low speed efficiency.

I agree! The fan's rated at 2100cfm @ 0 static pressure. The fan does flow incredibly well, after testing it became pretty obvious why they would patent the design.

Without a doubt Chris! Sending you an email regarding your other inquiry.

Received my unit last week. Unwrapped it last night. Fit and finish is excellent. Looks good, and the flanges cover the radiator well. A big improvement over my OEM unit, much less leakage.

Looking forward to getting the engine back in the car so I can give an instrumented test.

Cool. Should be pretty easy to calculate the speed at which the flappers would have to open assuming the fan is already on. Take the surface area of the radiator (as seen from in front, account for the tilt). Express as x square feet. The airflow the radiator sees at speed is a function of that number and the speed of the car in feet per second (or per minute if you're working in CFM). Set that flow rate to be equal to the fan's max rated flow rate, solve for speed.

How are the flappers attached to the shroud? That's my only concern.

Note that in the Ron Davis examples shown and every production example I've seen they are riveted or screwed on. If they are held with adhesive on this one, I expect they will eventually fall off unless it is some expensive high-heat, adhesive.

Very pleased to hear your feedback and that you like the product Chris. The combination of this and the dual pass radiator will be a nice 1-2 punch dealing with the Texas heat!

They are attached using multiple one way pins that protrude thru the shroud and then lock into place. I completely agree with you Wanklebolt, using an adhesive, glue or epoxy would likely end up as a point of failure.

Two questions for you.

You stated the fans push 2100cfm, the Flex a Lite 420 pushes 2500cfm and cost about the same. So is this comparable in performance even with slightly less air being pushed through?

Also, can it bolt up to say, a KoyoRad or OE type replacement radiator?

Yes it is Jesus. We have been very pleased with the real world results from our fan/shroud assembly compared to the FAL units. The fan itself is extremely efficient and our shroud makes a significant difference due to how it pulls air through the radiator core. At high vehicle speed the flaps open to provide maximum (vehicle speed) airflow/cooling and at low speed they close which provides very efficient airflow across the entire radiator core.

During the design process we wanted to develop a unit that could be used with our dual pass radiator (fal is not compatible without modifications) as well as standard OE designed units and aftermarket like the Koyo.

Our unit achieves this and does an excellent job in cooling on the street and for competition events.

Anyone who bought this checked the coolant temps? Is it a big improvement over stock?

One last question, since this is made specifically for the RX8, is it plug and play? As in it has a connector to connect the fan without having to splice anything?

I won't speak for/quote customers directly but I will say we have received very positive reports from several.

The OE connectors with age are becoming brittle and are beginning to fail. Rather than hope one (or both) don't fail during the install or down the road, we include barrel crimps and shrink wrap to eliminate the OE failure point. This makes it a very secure and straightforward process to wire them.

If you don't want to crimp the connections solid, look into Anderson Powerpoles to replace the stock connectors. They are much more robust and will outlast the car. The 50 Amp version ought to be overkill enough, though the 45 or even 30 Amp version might be more sensible. Reasonably priced from the usual Intarwebz stores.
