hitting redline
#54
I understand the dynamics of what happens after 7500 rpms-it just seems more like its coughing then it does getting a better boost. Perhaps its just not a smooth transition between 7500-9000 when that valve comes alive. Guess Ill have to try it again and again to see. :D

3rd gear and RPM's
I'm sure this has been discussed elsewhere but I thought I would throw it in here as it seems appropriate. If you're gonna duke it out with the kid in the soup'd ricer you've got to be above 7000rpm.
Here's the trick I learned. Say you're cruisin along fat dumb and happy wringing out that 21.3 mpg in 6th gear. Suddenly you notice that lowered honda is sidling up along side to give you a whirl. This is the time to look at your speedo. Take that number, say it's 75. Now shift straight down to 3rd from 6th. Sound crazy? it is a little but your RPM will be 7500. RPM's are the same as your speed in 3rd gear. It's very handy and it puts you just where you need to be to rocket away even faster than the other guys auto transmission has time to shift down.
Be careful though if you do this without stepping on the gas the high rpm's and back pressure will slow you down very quickly and in a turn that will kick out the rear end
. thank goodness for DSC :p

If it wasn't safe to rev all the way to the limiter, then I would expect the Mazda engineer wizards to have set the limiter down at the redline.
And let's not forget this motor's development heritage. Here's a pic of the preproduction version (~2002) that sported a tach with tic marks for 10, 11 and 12 thousand RPM on basically the same engine (no redline shown):

All that assumes that you're enough of a STUPID *** to street race.

I heard that the RPM gage in the RX8 is off by 500 i.e. 500 more than what the actual RPM really is though. Not sure if its true or not.

Suddenly, your 8 wouldn't be so unique.
Enjoy your very unique 8!

Older rotaries used to get excessive wear and tear on the housings and apex seals beyond 7000rpm. I wonder if this is now improved??
personally i dont like spending too much time around 9000rpm

Second, define street racing. I'll admit to stepping on the gas once in a while and face it, this thread is about redlining the RX8. Redline in third gear is 90 mph and please don't pretend that everyone has only done that on the track.
Third, you're a hypocrite. In a thread about taking street corners fast you wrote, and I quote: "With my RX-8, I usually take the curve's recommended speed, double it and add 10, as a good rule of thumb." Then you have the insolence to call me names for something you admittedly do.
I do understand that you don't want people to street race and you're right and I support your position on that but get some manners and stop bitchin' people out with your 3rd grade put downs.

as far as gas milage goes, i have a 92 4 door accord, and thats what thats for. bought me this RX8 with gas milage NOT in mind, just pure fun. :D

Actually, I am rather happy today as I just had the KC Dent and Ding guy fix three door dings and she looks fantastic again. I even redlined her a couple of times on the way home. A couple of you have mentioned the redline warning tone and I have never heard it so I listened very closely today and heard it this time. Certainly not as loud as it used to be in the RX7.

Like you said, the engine will be in the power band, just shy of redline for extended amounts of time. So, did you have problems with temperatures and where did the needle end up on your guage? Also what was the outside tempersture, this has always made a huge difference in my experience?
Thanks,
Thanks,
Or I could bring up the thread about how rotary engines may get rebuilt once a year in the racing world while piston engines have to be rebuilt after every race!
Or I could talk about how at high RPMs the rotary engine self cleans as carbon is broken down in the rotor housing
or...

Lets just say you DONT have to worry about heat unless it is 120F out and you removed your oil coolers :p
