Hi, i just bought my rx8 yesterday and i was wondering what rpm to cruise at.. in my friends s2k your supposed to cruise NO lower then 3k... in my old 911 it was no lower then 2k, this prevented carbon buildup... what is the mark on the rx8? 3k?

 

idk,it really depends I'm under 3K a lot when just driving.

 

ehh im anywhere from 3-5k and the occasional redline

 

I tend to keep it close to 3k when cruising. As you get closer to 2k, the car starts to get really sluggish. Just keep it somewhere under 3600-3700 and you'll be as efficient as possible. Don't forget to redline though! :P

 

lol, i drive it like its meant to be driven, infact, i might redline to much :P

 

i stay around 6 or 7. sometimes i go up to 11.

 

I usually keep it between 3~4K when cruising.

 

? u ask ask if there was a switch or lever to control this...

once u get into 6th gear at cruising speeds, your MPH determines your rpm. it's not like u have a choice what RPM u want to cruise at. LOL well, the only choice is to slow down.

ex: 85+ MPH means you'll be cruising @ around 4k rpms for the 6-MT.

 

3-4k around the streets.

 

I generally stay between 2-4k when I'm driving like a normal person. A lot of the time i find people in front of me don't speed up fast enough to warrant a downshift for power when I've slowed to 2000RPM.

When I'm having fun, I cruise in the 5-7K RPM range.

 

3-5K. Redline every other shift.

 

Turns on "gushing mode"

See?!?!? That's whats so cool about this car! You can baby around at 2-3k rpms and settle into a 60 mph groove, never getting above 3.5k

.. or ...

You can make this baby howl! Don't even need to shift from 2nd gear unless you're going 80 mph! Spend all day in 3rd gear : Rooowwwrrr !! :

It's good either way. No less than one redline a day, though.

3000rpm is a good median point for normal cruising, depending on which gear you're in and how fast you're going.

 

I cruise 80-90 mph, so that puts it up pretty high. Steady low rpms has not been mentioned as a good way to burn out carbon, in fact, people with automatics who do that sort of thing frequently end up needing new engines more than other groups who bang on it.

 

That is simple.
Run at whatever you want to.
To prevent carbon build up, just redline it regularly.

 

You must spend alot of time in traffic.

 

true, on my 80 mile commute to work Im cruisin at 4K @ 78-80 mph.

 

80 mile commute that sucks...

 

i shift under 4k then cruise under 3.5k....on the freeway, every 5mph over 65 your spending another 10 cents on gas...

 

LMAO!! I watched that just the other day.

I do 2-3, sometimes 4-5 for the hell of it though. It's so smooth you don't notice.

 

huh? Is that a one time fee?

 

On the highway I cruise at 70mph, 4kRPM in 5th gear. Why? It soothes the savage Greddy exhaust note.

 

I usually try to keep it as close to 3k as possible. If I'm feeling frisky, 5k.

 

3-3.5k normal cruise speed for me. Never like to let it drop under 3k.

 

Usually cruise around 4-5k in sixth, using the carbon build-up as an excuse.
