Atlantic Canadian RX-8s: First "Dyno Day"
Well, more like a "Dyno Evening," but that's not the point. 
In the interests of the ongoing horsepower debate, as well as to settle my own curiousity, I have booked the use of the Dynomight (www.dynomight.ca) DynoJet chassis dyno for this Friday, Sept. 12th at 6PM.
My self, and Jasper the 2nd (plus friend) have already confirmed our attendance, and I have started putting word out to the local dealerships that I know to make their customers aware as well.
If anybody else in the region is interested, drop me a message, and we'll get you on the list.
The details:
Cost: Currently, the worst-case price is $60 + taxes. With the 3 cars we have attending right now, this is the cheapest route. However, with a few more cars, it will be cheaper to move to a per-hour price, and the price will come down from there.
Location: Burnside Industrial Park, Dartmouth NS
10 Ilsley Avenue, Unit 15. The awning out
front says "Master". The dyno willl be set up at the side of the building.
Date and Time: As above, Friday Sept. 12, 6PM.

Great News, Redshift ! Please let us know what the results are like.
Oh by the way, you know how some of us are saying they are feeling a definite boost of power above 6250 RPM while some other owners are saying their car start losing power above 6250 RPM ? Can you please maybe make a note of which car has which behaviour according to their owners before the Dyno Test ? ( and also their average fuel consumption numbers please ? ) I dying to get some data together and try to draw some conclusion from them, thanks a lot !

No, mine and Redshift's are both GTs.
There is a GS around here but I don't know the person, other than his name.
I don't notice a drop in power after the third injectors kick in, but I don't know if I'm getting as much kick as I should be either. I'm still getting some soot on the tailpipes though, so I'm assuming it is still running rich at the top end.
I usually get about 13 to 15 L/100km normal driving (mixed town and highway, mostly short drives). I did a couple of two hour drives this weekend (mostly highways and back roads at highway speeds) at got a 12.1 L/100km, my best so far.
I've got over 4000 km on the car now, btw.

Smoker: No problem. We'll gather up and pass on as much information as we can. DynoMight just bought a brand new A/F sensor as well, so I think I'm going to pay up the extra $10 or so that costs so we have that information as well.
As for fuel economy, around town I've been averaging 16-17L/100km. My best, on a long 6th gear highway trip (Halifax to Moncton and back) was around 12L/100km.
As for the soot on the tailpipes Jasper mentioned, my tips are black within a day.
Car has just over 4600km on it as of last night.
Got my oil changed at 1099km. I've added a full 1L worth of oil since then.

I'm planning on getting the A/F measured as well.
My friend's A/F ratio probably won't be helpful. He's dynoing his Civic.
I put in a call to my dealership and asked them to give the owner of the GS a call and see if he'd be interested as well.

I called Mills yesterday to contact the person who bought their GT, and I'm going to give Steele a call today.
I know City Mazda in Halifax sold a Silver one, but I don't know anybody at that dealership, and I've never actually seen the car around.

Jasper_the_2nd and Redshift, thanks a lot in advance for your efforts.
So when you guys are done, hopefully we can draw some relationships and conclusions between: HP, A/F ratio, Fuel Octane Level, Fuel Consumption and maybe model (GS/GT) type.
Can't wait ! :D

Note to self: Must stop assuming car dealers know ANYTHING about actual cars.
On the way back from a meeting today I passed by City Mazda in Halifax, so on the spur of the moment I thought I'd stop in an pass the word. Sales Manager uy looked completely baffled at the whole concept of a Dyno..(*blink*..What's a Dyno? *blink*) ... anyway.. he was nice enough.. pretty dismissive and standoffish though.
Glad that isn't the dealership I'm going to have to deal with (for however long that may be...)
I left my contact information so that he could pass it on to his customers.. judging from his reactions he won't bother though.
Anyway, I'm looking forward to this Friday night. Should answer a lot of questions in my mind.
Still working to recruit some more cars. We'll let you guys know.

You're still surprised that dealers know very little about the cars? So far, Steele in Dartmouth was the only dealership I've found that gave me a sense that "car fanatics" work there....
Anxious to hear the dyno results, well, more curious actually. I decided to enjoy my car that first morning at Steele. I'm an engineer, so fuel efficiency and hp are a curiosity, but probably not going to have much of an impact on my enjoyment of the car. On the drive from Halifax to St. John's I got 12.1 L/100km, around town I'm getting high 13's to low 14's - consistent with Redshift.
My pipes are havily sooted withina day as well - I'd expect some, but this is a lot. More evidence of this rich fuel map for the first x km. Is there any way we can learn what mileage the 8 will switch to the leaner mixture? Or even if this is real?
I have to say, I am somewhat jealous of you guys being able to get together with other 8's. I'm still the only owner in my area - although I did hear a rumor that there was a GS in central Nfld somewhere...

bg parsons3,
You're just a "short" boat ride away, you should come over!
It's only 10 or 12 hours to get here, isn't it?
It would be cool if you could though...

Barry, glad to see you are still alive! I was just thinking the other day I hadn't seen you in a while. I figured your RX had gotten personal with a Moose.
I hadn't really forgotten that people at dealerships rarely know anything about cars, but I always try to start the conversation assuming they aren't idiots... unlike the way they tend to treat their customers. (But I agree, people at Steele seem like they sell cars because they like them, not because they coudn't get a real-estate license...)
News: He's got to check his Golf Schedule, but it looks like we have a Reg GT coming out Friday night, and I'm working with Tim at Steele on a 4th RX-8. No word back from Truro yet.
Mileage: Got gas last night. First full tank with my daily commute now that traffic has returned to "normal" after folks went back to school. 14.8L/100km...

Will miss out on this one .... get some pics if you get a bunch of 8's together. I'm thinking a shot on the waterfront with George's Island in the background - be a nice shot!

I'm definately bringing my digital camera to get some shots.
We'll have to see about getting some nice posed shots, but it'll depend on the light conditions I guess.

Just an update. I haven't heard anything from the Red GS owner, so it looks like it will probably just be the two cars (8 and Civic) coming up from New Glasgow.
Any word from Truro yet?
And I'll have my camera there too. And I think Craig is bringing his video camera...

Back from the dyno. Looks like Redshift hasn't made it online yet.
We had 3 RX-8s, all GTs. My silver, Redshift's blue, and a red.
Also a selection of Hondas, a Feiro, and some crazy racing bike.
The red RX-8 owner's wife had a Beemer, but we couldn't convince her to put it up on the dyno.
We don't have the data files yet, since the dyno owner will be emailing them, but I have some printouts, which will do for the moment.
The graphs look remarkably like the U.S. ones. Our numbers were a little lower, which is probably just a variance with conditions and the dyno (it is a portable, so I'd assume it's a little less accurate, or succeptable to being a bit off compared to a fixed one). Or it could just be the Canadian HP. :D
The max rwhp from any of the runs was was 168.3 with 125.3 for torque. Just happened to be my car. :D Redshift's was about 1 lower on HP and .5 lower on torque. And the red, which had significantly less km on it (I think it was around 2500) was a bit lower at 158.3 HP and 123.5 torque.
And the graph shapes looks just like what we've seen, Nice and smooth, bump at 4k for the secondary ports, big bump at 6250 for the tertiary ports but HP is still smooth, then 7200 big bump, for additional air flow or something, and things just go ugly.
We each also did a run with the air/fuel sensor on. Again, the graphs are basically identical (which is a good thing).
Ratio starts at about 15, drops to 12 by 4000 rpm and stays between 12 and 13 right up to 9000 rpm.

168 WHP is a total disaster from 237 HP engine let alone 247 HP engine! That is with a 6-speed manual transmission that should have losses no more 15%-17%.
This is a more proof that Mazda is still lying. if you do not file a class action suit for this, I do not know what you are going to do 1 month from now.

I believe everyone was running premium, but I'm not sure.
A definately think I'll be calling Mazda on monday, to see what they'll say.
BTW, I put up some pictures, including a couple of mpegs of the red RX-8 and a Civic doing runs on the Dyno, on renesis.ca The sounds isn't the best, but you can still here them wind up pretty well. The mic in my digital camera isn't the best.
I'm including a link, since I put the pictures in a sub-album, and for some reason it isn't showing up in my main gallery.
