Finally Oil Cooler Fan Kits!!
 

Now Available!

One of the most common causes of RX-8 engine failure is excessive heat. High temperatures have long been the enemy of rotary engine longevity and performance. There are many effective modifications that can increase the cooling capacity of your RX-8s primary cooling system – the engine coolant, water pump and radiator. Until now there have been few ways to address the secondary cooling system – the engine oil and coolers.

The oil system of the Rotary provides approximately 30% of the engine cooling.

During normal operation engine oil is routed through the eccentric shaft into the rotors to provide cooling and lubrication. When engine oil temperatures are reduced, more heat is removed from the engine reducing demand on the primary cooling system.

Since the RX-8 does not come equipped with an oil temperature gauge most owners are not aware there is a problem until it’s too late and they are facing engine failure or low compression.

With another hot summer upon us oil temperatures in street applications are extremely high and customers are reporting engine operating temperatures in the 240f range. If the past is any indication, this will lead to yet another round of summer engine failures.

How it works:

During low vehicle speed or in stop and go traffic the lack of airflow does not promote efficient heat transfer from the factory oil coolers. Using our oil cooler fan kit (or kits) with the factory installed oil coolers significantly improves air flow across the oil coolers lowering oil temperatures and assisting in the reduction of engine operating temperatures.

The kits are available in driver, passenger, or two sided configurations to meet any level of cooling needs.

The passenger side kit is compatible with automatic transmission cars as well providing additional transmission cooling which can extend transmission life.

Protect your investment by lowering engine oil temperatures and extending engine life.


Helps prevent:

* Overheating
* Low RPM drivability issues
* Heat related performance loss
* Lower engine compression
* Issues with seals
* Rapid deterioration of water jacket seal (the equivalent of head gaskets)

Kit Includes:

* High flow fan
* Custom RX-8 specific fan shroud
* Mounting bracket
* Smart fuse holder
* Heavy duty relay
* Plug & play harness

These kits are ideally suited for daily driven and autocross applications!

Kits are on Sale now for $175 and can be purchased via our site here.

wow nice!

/\ signal off the first stage rad. fan relay would be a good option ......

Yes, it can be wired two ways.

They can cycle on and off based on engine temperatures and vehicle speed and will continue after the engine is turned off.

or

It can be wired via Ignition when the vehicle is turned on.

Very nice.. Good job brice! I might be ordering one after I move to TN

Not right now, but in time I'm going to need two. One question though, when you buy these kits should we cut the vents on the inside of the fender a little bigger since it will be forcing more hot air out now?

Great job by the way!!!!

these will be on my to do list

OMG, perfect timing. $175.00 for each side? Discount for both? I didn't know you guys had a fan control kit either.

Also, it says plug and play. What does it plug into?

how come it says 175 here but but 135 on the site... and is that for one or a pair

i guess i know where all my 3 month bonus is going to ~_~,

will i ever own furniture such hard profound questions, does the front bumper need to be removed ? or just the plastic fender liner (i ask because i forgot to leave slack in the cable for the jamming heads >_>)

wow very nice, i like the idea.

I've thought up of this idea about two years ago but I couldn't find a fan small enough to go behind the oil cooler from my local auto-parts store.

I like this. Easy to instal yourself? Come with directions?

wow, nice :)

I think Im ok ... I think my cooling system is fine for now ...

if I have the extra cash, why not ?

Great work man !

heh, down here in texas its been hot, everday is a 100+F day. a little extra cooling never hurts, was thinking of water mister on them

Brice I have a question as well if you don't mind...

I know you removed the wheel well lining to take pictures but are you able to still use the wheel well plastic? I always found it to be a tight space but I couldn't tell by your pictures.

Great product! I've always felt fans were an excellent idea because it gives you extra cooling when you need it but you can turn them off in the winter or colder months.

Can these be shipped to Australia??

great product :icon_tup: +1 what Flashwing said, pics with all cover up will be great :) as for the plug and play, do you mean it will work like mazsport fan kit before? i think that will be great too, where it can detect when it should on and off by itself ;)

you should recommend to open the air vents in the wheel well too imho :) Not much, slightly opening them could avoid the "rebound" of the air pushed by the fans ;)

We ran this on a local car and we experienced a 30 Deg. F drop in Oil Temps. we did modify the ducts behind the wheel liner to increase flow.

Of course PM me for ordering options and discounts.

You are mixing the oil cooler fan kit and the standard fan kit.

Front bumper doesn't need to be removed, it just makes for an easier installation, it is recommended of course.

Absolutely it comes with directions and I think it is easy.


Yes sir as I responded above it is not necessary but we did to increase flow.

Absolutely. Orders can be placed on the website.

Correct Plug and Play and automated as well... :)



Thanks for all the positive feedback we have two more products to wow you, that go hand in hand with this as well :)

I am more excited about those releases because they are more eye catching if you know what I mean :SHOCKED:

This is nice! I'll be soon ordering these fans.

wow this is awsome, this is defenetly on my next to get list!

I have an engine oil temp and I completely agree with the oil temp issue. Its great while I am driving...but when I sit at a stop light...it starts to climb considerably fast. This cant be good for the engine.

I am interested in what "two other" producs you are talking about...if its improved replacement oil coolers...I am in...;)

Chris

do those mounting spacers relocate the bottom of the oil cooler below the front bumper opening?

Yes I think I need some! haha

If I think what you are asking, it does slightly move the oil cooler down but not that much, I will get a hold of the field tester and have him take pics on his car.

waiting for the pics :) now i got another wish list to add ;)

Oh boy..............there goes more money outta my wallet! I wanna see the pics and Brice........how would it work with the ole Mazsport cooling mod? Is it going to use the same relay position?

yes I need to know this as well,,, my new aftermarket bumper comes with oil cooler shrowds that replace the oe's... I dont think it would mate with my bumper in its current configuration if it indeed drops the hieght of the coolers,,,

I want sooo bad....

Nice

Wouldn't the fan impede the airflow at high speeds? Say like 100+ Mph, on track, of course. :)

Yep! I was factoring that in. :) They can be used in conjunction together.

Impede, no. With our testing there was no loss or gain at high speeds we couldn't improve the efficiency at higher speeds. Even at 50MPH+ the cars efficiency for oil cooling was as good as it can be. This is geared towards the daily driver/autocross driver so that in low speeds and idle the car oil temps will be lower and not climb like Chris has stated.

Measured 1/4" lower with the spacers on there.

I apologize if these questions are somewhat noobish, but I'm going to ask anyway!

Regarding the two wiring options:
If the kit is wired in such that it kicks on and off at temperature and speed (I'm assuming the same time as the radiator fan), then the kit basically only helps bring down peak temperatures more quickly, right?
If it's wired in to the ignition, then the fan basically runs all the time? Is the kit easy to disconnect in the winter when we'd want our car to reach temperature?

Other random questions:
How much power does the fan draw?
Temperature drop for one fan vs two fans (The point being if two are really needed)?
If only buying one, would installing it on one cooler or the other be better (I'm assuming the fan is interchangable between sides)?
If one was to purchase your fan control kit (can you explain how this works BTW?) , I'm assuming the oil cooler fan would tie in with it?

Correct it will bring peak temperatures down initially and maintain the lower temps it will not wait for the temperature to go back up before it comes on. Once it is on it will maintain those low temperatures.

The kit is easy to disconnect with relays and the wiring if during the winter you wanted it off.

One vs. Two Fans warmer climates are recommended to have two units to maintain the lower temperatures while the single fan would be ideal for those in the north that only have partial summers.

If you buy one it is not interchangeable you have to pick which side, if you are going for one it is recommended to do the Drivers side Oil Cooler.

The Oil Cooler kit and fan kit were designed to be able to work together, so those that have the cooling kit would be able to have the Oil cooling fan kit as well without issues. The cooling fan kit is used for the radiator fans so that you can have a cooler running RX-8 as well as colder A/C.

Also it appears there is an issue with IE on that portion of the site for which reason we are still figuring out, so anyone that is having issues ordering please let me know and I can manually process your order.

Kits shipping out today!

These are going to be at this sale price for a limited time so snatch them up!

Thanks for shipping out fast

Hmm interesting.

We have corrected the issues on the website concerning IE mixups.

We also have added more pictures to the original post.

have you tested them out so we know what temps to expect?

Absolutely, we would not bring a product to market if it wasn't thoroughly tested.

An avg 30 Degree temperature drop is to be expected with this product installed.

have you found that lowering the oils temp also caused the coolant tempt to come down some?
olddragger

Lowering oil temperature reduces the amount of heat in the engine allowing the primary cooling system to work more efficiently which will further reducing engine operating temperatures. So yes the coolant temperatures will go down as a result as well.

I don't quite understand this. Being that the fans only kick on when the temperature gets hot enough, they would just maintain the temperature right?

Wow this is actualy a great mod for any rx8 owner who want a cooler running 8!!!

Just a couple questions:

I'm assuming the 30 deg drop was with 2 coolers. Have you tested the temperature difference with just one cooler? How did you modify the ducts behind the wheel liner? Any idea as to how effective would the cooler be without the duct mod? Thanks.

ANY rx8 owner should want a cooler running 8....since that's a MAJOR problem (not really problem but downfall of the rotary) with the rotary......anything to take heat OUT of the engine is better weather is have pistons(ewwwww) or rotors...

After sitting in Vegas traffic for hours last month and seeing temps of 227F+; im definitely gunna need this soon lol

The 30 Degree drop was with only one oil cooler actually, it was the drivers side.
We modified the ducts like others have with the DIY oil cooler duct mod where we took a dremel and just made the openings larger.

Without the duct mod we would still expect a significant temperature drop but just not as much.

Thanks for the info! Placed my order today.
