the case of the missing 22kW
#26
BTW, I am a little concerned about the "auxilliary port" / "tertiary port" (there you go wakeech you have another half a supporter :D ) issue, but hopefully Mazda had enough time to take care of it BEFORE final production as opposed to starting out the debut of the RX-8 with a recall.

We used the word "tertiary" all the time in my biochemistry classes back in high school. I always thought it was a widely used/accepted term.

Well, before your last post, only Wakeech insisted on calling that 3rd Intake port "tertiary port". Everyone else including Mazda called the 3rd Intake port "auxiliary port".
Consider this: those of us that had 2nd Gen N/A RX-7 FC3s's know them as 6-ports. I recommend if you want to better communicate with existing RX owners, esp. FC 6-port owners, everyone call the ports that open at high RPM's "The 6-ports."
rotarynews.com -> wouldnt it have felt pretty choked by redline then?

They may be electronically activated, but they're still mechanically operated. It's not a question of whether the ECU chose not to open them, it's that the mechanicals were unable to comply, due to being stuck or broken.

So can we say then that NOBODY has timed a properly working rx-8 yet then?

Nah, the article said it was specifically a software bug. As an embedded programmer, that just strikes me as a very dumb mistake. All I can think of is that maybe they fitted the 'low power' motor ecu to the 'high power' cars. Because you can get 'low power' & manual somewhere in the world cant you?

I agree with Wakeech's philosophy of the possibility of having more ports in future :-)

Ok, so I read here in the US Sport Compact Car, which also has the car down some 40 horsepower. And reference was made that the other magazines that tested 0-60 times, which was done in 5.9 secs, did their testing with the horsepower deficit.
So it stands to reasons that with the additional power, 0-60 should be in the mid 5 second range.
Don't get me wrong, I am satisfied with the performance as it is currently reported. However, if I can get the extra performance from the missing 40 hp, I will never complain.
I think black with the red and black interior with every possible option. Yeah!!

i honestly don't see how more ports would help... please elaborate. the way i see it, there is a finite area you carve out of the side housing before you cut into the compression stroke and/or start letting apex seals slide out. to me, more ports = more closed ports = less air

but this isn't exactly what i meant: more ports equals more variability... even if it was just a 4th (quarternary, yes i looked it up) port on the intermediate housing (above the secondary port) it'd make a huge difference to the dynamics of the engine, allowing it to take it hard up to ten grand... with a third (central) bearing (which would be really spiffy, and sort of go well in a beefier intermediate housing to make room for those quarternary ports) stock rpm limits of 10.5k rpm could be achieved (at costs of weight, complexity, money, etc)... it COULD be
