Redlining
I am new to driving the RX8, I keep hearing that you need to redline it often to burn off carbon. What are your suggestions on what gear to redline it in i know its a pretty dumb question but I have to get use to redlining i keep thinking I am going to mess up my engine.

Unless you are going downhill, it might be hard to redline in sith gear.
Just drop back one to fifth and you are good to go. Make sure you bounce it off the rev limiter 6 times before you back off the go peddle.

ohhh sunovabitch!
OP, these guys have great hearts, but they're just messin with you. redlining in 2nd is best. 1st or 3rd won't hurt. Just make sure you have enough safe highway!!
Also, this type of info is not at all hard to find (hence the sarcastic remarks...). Click the link in my sig to learn to search the forum more efficiently

most people here will grill you on the search function unless you have run accross new ground breaking material. but i generally do a 2nd and 3rd gear redline pull on the on ramp going to work once a day. im also a very "spirited" driver so maybe more often then that, but 2nd gear is probably the best to do it in... drive safe!!!

And dont fear the "beep." The fuel cut i in there to stop you from doing anything stupid. Only way to over rev your motor is to be going 70 or so and downshift to second. Zip BOOM!!!

Thanks guys I will be redlining more often I had my check engine light come on and code P2070 was the issue (SSV). The guys at Auto Zone reflashed it to make it go away so I think it's carbon in it so hopefully I can burn some of it out and has anyone tried seafoam?

I usually go with 2nd... But a redline is a redline, regardless of gear... Since you are new to the 8 it will probably sound pretty scary to you initially for the engine to be revving up that high. Don't worry, our engines are meant to go that hard so you aren't going to mess it up. Your engine will love you for doing it... And enjoy hitting 9k rpms!

The SSV code may be gone for now, but it will probably come back as the valve gets more sticky. The valve gets contaminated by oil breather vapor, and by some accounts, creeping carbon deposits from the intake ports. The most permanent fix involves removing the SSV and cleaning the components. This is also detailed in a separate post.
Another cause for the code might be a faulty strike switch, which tells the computer the valve is functioning. This can be tested on the car, and is detailed in another post.

SSV has nothing to do with engine carbon. the SSV is on the intake manifold.

Yesss.... I like to practice my Fast & Furious driving... You never know when you might want to flip your car out on the highway and accelerate in reverse while going 80mph+... man, if only my reverse went that high. I guess I will have to do it on indicated 30mph speed limit roads...
FWIW: premixing helps keep carbon at bay... I have been against premixing in the past and im still at bay whether its worth it (our engines lose compression randomly it seems) but if anything I decided to premix 4-6 oz with every FULL (13-14.5gal) fill-up to help keep carbon from sticking and to help lubricate the center apex seal.
But dont take my word for it, do your research and make up your own mind.

I disagree with the red line a day crowd. Just look through the "new engine" threads and find a large number of those in need of a new engine saying they did that and wonderin why it broke. Freeway entrance ramps are the most convenient/safe way to street run it that hard, but almost guarantee the oil isn't up to temp. Without an oil temp gauge, there's no way to know. It does make sense to exercise the SSV however, but that only takes 7300 rpm or so to accomplish.

Because in mild to cold air temps, it takes a very long time to warm up the oil on city streets (on the way to the ramp). It probably takes less time at idle in the driveway since there is no airflow through the coolers in that condition or about 15 -20 min at 70 mph on the expressway. The Series II recognizes this problem by lowering the rpm limiter based on engine temps - I suspect based on the bad experiences with the Series I. In non-desert running, cold oil temps are a very common problem with these cars. Search "milky oil".

I wouldn't worry too much about redlining once a day, it's more about your driving style\loads\rpms.
