Brief update guys!
It's been asked a couple of times so I wanted to let those of you with automatic RX-8's know that this fan and shroud assembly is compatible with your vehicle as well! They have been customer installed and the built in transmission cooler lines of the OE radiator will clear the shroud! These are in stock and ready to ship! Thanks guys, we appreciate your business, Scott |

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. |
Skc, wanted to answer your question. Keep in mind I did it with no engine in the car so results may vary.
On my radiator the bottom posts lined up okay with the fan shroud, but only one top post worked. It's less than perfect but should hold up. I can try and get pictures if you would like. |
If combined with the rx8performance radiator, will modification still be needed to the factory airbox tray and battery tray, or does this fan leave enough clearance without any modification?

Yes it can be used with our dual pass radiator without modifying the battery tray, we have a additional hardware kit that will increase the clearance slightly. What battery are you using currently?
Battery is smaller than stock, so I have room to modify the tray if needed. I'm a bit more concerned about modifying the stock fans and the interference with the air intake. I don't have an AC condenser, so it should be possible for me to space the radiator down a little bit to make more room... |

Thanks for the reply. I'm going to take another look at it this weekend and decide what direction to go...

Either way I don't believe it would be an issue as we haven't seen it as one here at our facility with any intakes whether F/I or N/A applications. |
Just curious if you know what the factory PCM programming is for how the fans operate when the RX8 is at speed? There seems to be some question about whether they turn off above a certain speed, operate on low speed only, or operate low/high speed based on coolant temperature the same as idle.

Well there is an adjustable speed parameter in the fan control section of the Cobb AccessTuner software, which it comes from the factory programming, but the actual definition/description for it was never clearly documented. I'm sure Mazda Megalomaniac might know or claim to any ways. I never actually tested it and my car is still on jackstands for at least another month.

I know 100% for sure the low speed fans stays on and am 90% sure the high speed fans turn off at the set speed.
Was going to test the effect of this at the track last weekend but we ended up deciding it may cause more issues than it solves. |
Thanks, it's not possible to determine without a working car, otherwise some lights wired into the relays make it easy to figure out otherwise.
