Before shutting off your RX8
If cold outside, I rev to 4-5000 after parking, let off the accelerator and turn it off about the same time. I never had to shut the engine off when not fully warmed, so cannot comment on the usage to prevent flooding. The injectors and accelerator are electrical, so when the key is off, those are off too (hence useless to push the pedal after the engine is off - on RX8 at least). The oil pump is mechanical, hence it does not care about ignition off or not - lubrication and oil pressure depends on RPM, no issues to rev when engine is off. If thinking of the oil metering pump - it rarely injects oil anyway, so it does not matter.
Does it help anything? Probably not, but it cannot hurt either, so I consider this "prevention." Just like premix and many other quirks learned since owning the RX8 for 4 years... Don't care what people think - if the car needs it, the car gets it :o) But that's just me.

Thanks for the info.

i bet tats just the sound of normal intake, u just only hear it when u do this because the engine stops exploding and you can actually hear the intake.

No offense, but shouldn't you learn about the car yourself instead of listening to the dealer? They are glorified salespeople anyway. At least I don't expect store clerks to teach me how my TV work, and I don't care how much they can repair of it :P It surprises me how little interest people have in an expensive possession. I have read a million things about this car and haven't even got it yet. People are different though.

Service people told me that as well, said that "the car was not meant to be driven by grandmas" and needed to be rev'ed a lot. I don't do it unless I'm only moving my car around the driveway, otherwise its always warm from the drive. If you lived in a colder climate I could see this being a problem though. Good luck!

not to be insensitive, but do none of the newbies read the quickstart guide and/ or owners manual... at all?!!
all the basics are covered in that quick little pamphlet that takes less than 5 min to flip through. mazda also provides a DVD with each rx-8.
good grief.
we were all newbies at some point. but, some of us know how to turn a page... or pop in the DVD- which btw also takes less than 10 min to watch.

I've been hitting 6K or higher and then killing ignition as the rpm drop. It doesn't smell so good. Almost as if something is burning or has melted. Same thing happens when rev to redline 3 or 4 times in a row.

Those aren't always the same thing: when my car is in neutral the clutch is usually disengaged (for example, right before stopping at a red light I typically put the car in neutral, disengage the clutch, and then use the brakes to stop; I don't put the clutch in again until the light changes). So is it bad to rev in neutral, or bad to rev with the clutch engaged?

Bad to rev with the clutch engaged because then the transmission is connected to the engine and it is not made to do 9k in neutral.
Of course, you get that nasty electrical burn clutch smell anyways if you do it a couple of times anyways like user 24 described.

All this time I experimented with the rev before shutting down, even though the car is fully warmed up. Sorry, but it does nothing. Rx8 is much better off just twisting key in the ignition to off, if it is already warmed up. However, if the car is not really warmed up yet and for some reason you're late to work and must shut it down immediately, then 3000 for 10 seconds is the proper procedure to reduce the chance of floodz.
Once again the dealer employees have misunderstood rx8 treatment, in your situation.
