i know i dont know much about cars but from reading the second link i believe i understand what it takes to maintain this kind of car and i was simply a little confused when it came to revving the RX8. for the past 5years I have driven a 1996 Toyota land cruiser and i have taken good care of it. the MPG and The Oil that the RX8 uses wouldn't be a problem for me. atm i am just doing research and reading a lot of things from this forum. i figured id post what you guys would presume to be a dumb question here in hopes of clearing up how to rev.

Serious ultra-super-dumb question: Warming up the car before driving. Until the temp needle gets just before the center, until the needle moves a little, 1minute, 30 seconds? or does it not matter as long as the first 10 minutes are driven without going over 3k revs?

So many people are joking that you will never know who is serious who's not.

I have an idea, lets change the name of this thread to "lets have fun with dumb questions and flame each other (no seriousness is allowed)"

I still do not know if you are serious or not. I will answer your questions just in case you are not joking. I should tell you I am no expert and I am not a mechanic and this is only what I think.

is revving something you do when you down shift so that the RPM get to redline? You can down shift if you like. What I do and I think most people do is this. While entering highway in second gear I accelerate to reach redline and as soon as I hit red line I change gear to third gear (MT).

I am guessing it is like putting the car in neutral and pressing on the gas but instead it's done while driving? Yes it is recommended to do it while driving in order to clear the carbon. I do not think this is proven but it is something recommended by rotary enthusiast for a long time.

down shift so that the car reaches redline faster? Do as you wish, it is your car and you are the one in driver seat. If you want to reach it faster why up shift fast then down shift? You always start from stand still right?

if it is like that, would pressing on the gas pedal after hitting the redline be bad for the engine? I do not think it is good for any kind of engine or car to go past redline or be kept at redline for long time. You reach redline and up shift. There are bunch of engineers that decided what should be the max RPM for a car and
going above that might damage your engine or transmission so why risk that?

essential how long should someone keep the RPM close to the redline? Just reach it and upshift.

Again this is what I do and by no means this is the best thing to do. I don't even redline everyday. Keep reading and decide what you want to do with your car.

You can rev an engine in any car regardless of the transmission.

What you are inquiring about is termed, 'redlining', which is the process of bringing engine speed to it's specified maximum revolutionary speed.

Revving, although a similar term, does not necessarily mean 'to bring to red-line'. Instead, it means to move quickly through a cycle, or to bring to speed quickly. (i.e. to rev up your engine)
Many times, this is performed in a neutral transmission setting where the accelerator is pushed repeatedly or held to bring the rpm's up quickly. This does not have to be done in neutral, and by definition happens anytime the engine is brought to a higher engine speed quickly.

I hope that helps.

Also, the comment about having an rx8/posting a pic is just humor. We just like seeing happy owners post pics of pretty cars.

Where are the best points to place my jack stands (I know there's at least 20 threads out there already on this -- just don't feel like searching)....

So I guess my real question is... do "lazy" questions constitute as stupid ones too?

Would it be smart to weld my diff?

Is it cool to have a Methanol tank in the back seat? Or trunk?

What kind of oil should I use.....should I use Synthetic oil..or is it evil oil that wrecks your engine if you even think about putting it in the car?

Is there a God....does he drive a rotary vehicle.....Which one...old school RX-3? Or new school MM turbo charged RX-8? How long did it take to get his KIT

Does the BHR midpipe work on the series II's? Do you have to order it with the second O2 bung, or does it already come with 1 in it that'll be used for the stock O2 sensor?

I actually tired searching but I couldn't read the 100 plus pages in the bhr midpipe thread.

It should work on Series 2. I haven't seen any notations that the series 2 exhaust changed at all.

No, you do not have to order it with the second O2 bung. That is just BHR making the option available to people that want to run a 3rd O2 sensor, typically a wideband sensor for gauges or whatever.

Yes, the bung it has by default takes the OEM rear O2 sensor perfectly.

That's what I figured but just wanted to make sure. Thanks

Hope you're still watching this thread, despite it not being what Brettus intended.

No need to warm the car very much before driving. It's better to warm an engine by driving gently than by sitting and idling. The gearbox and rear end don't warm up at all until you drive.

The owner's manual says 10 seconds. That's enough for the oil pressure to come up and things to stabilize. The manual also says longer if it's very cold, but doesn't say how much longer. IMHO, when it's very cold it's reasonable to wait until the engine starts to come down off fast idle.

3k rpm is a little low for any kind of reasonable driving. There is a rev limiter until the ECU thinks it's warm enough. As far as how soon you can hammer it, that's really a matter of oil temperature coming up. Since we don't have a stock oil temp gauge, it's just a guess at how much to wait after water temp is up to normal.

Good advice . I never wait even a second after starting cold before taking off . Then again , I have a driveway that is downhill and a very quiet street (so I can accelerate very slowly) so I hardly have to touch the throttle for the first minute anyway .
As a rule of thumb , I would allow 10mins before hammering it .

/\ both good intakes with minimal gains . AEM is more useful if you later want to fit a turbo .

When I start my car in cold weather it is a little bit hard to change gear (it is a little bit stiff) but after driving for 5 or 10 min it becomes smooth. I believe it is due to tranny oil being cold. Is there an special tranny oil to use in winter or cold weather for our car? Right now I am using Red line MT90. I changed it a month ago. Is what I am experiencing normal?

A question on a side, Up to how many MPH we should be able to downshift easily to 1st gear? Do you ever downshift to 1st gear or using 1st gear only for starting to move? (What I am asking is should we down shift to 1st at 5MPH or to 2nd?)
