Article on new G35 Sedan HP
Good points about the dyno differences and the rev up vs. the non rev.
On the fuel side that is also interesting. 9/10 tankfuls I use Irving. I've read about many people complaining about their car pinging but have yet to hear a peep out of my car. On my trip to the US a month ago I used a couple of different grades but found my car did better mileage with 91 vs. 94.
A wider range of colours would be nice especially with the new model debuts.

As much as it is tough to admit, since the RX8 is a kinda rival, when I was at the TO Auto show not this past winter, but in '05, I must admit, Mazda was showing some really nice colours. I think most impressive was the fact that they were doing something other than playing it safe, and I hafta hand it to them for putting their cars into some classy looks. The MX5 and the RX8 were shown in colours like those I mentioned- a metallic green, a burgundy, and a plum. Panoz had a plum as well, and the Miata has a very similar line flow- really upscale [no I do not think these two cars look alike, I'm just referring to the line flow- lack of "flame surfacing" as Bangle would call it, rounded edges, and slippery over muscular overall emphasis of Miata Gen 2.]
I think Infiniti would do well to take note of how some class was added to both these cars, RX8 and Miata, by having some rich colours. While I'm not about to go buying that crazy light blue (Laguna?) that BMW's M3 is available in, I'd sure be interested in something other than DP or DG/SS.
On your trip Deane, was there temp differences? I just know that when we travelled a few weeks ago to Ontario, there were some 37C days back to back in Kingston, followed by some 18C days a week later. The car will always do better when it's scorching outside- no oxygen, so the map dials back the fuel accordingly. Reverse applies as well of course. I love driving in the late fall on crisp mornings for just that reason- car is gobs more powerful with all the OhTwo in the air.
Cheers,

Not surprised.
My buddy has the best example of the first gen RX-7- the final year GSL SE, including the 13B engine, and has babied it religiously. It's a beautiful car. He wanted to pick up an RX-8 when they were first intro'd to have the cars 20 years apart, but I was successful in convincing him to get his deposit back. (facilitated by the lemon law false hp advert issue). One of my bosses, a Brigadier General in Kingston, who's a big Madza fan, bought the 8. A couple years back, I asked him how his Christmas holidays were. He told me about having his car taken to the dealer on a flatbed one day, and the very next receiving the letter from Mazda about the cold weather starting problems [do not let go of the starter until the engine is running or it will be permanently flooded]. Ouch.
I get the impression that the RX-8 is a great car marred by rushing it to market too quickly, in response to the 350Z. Hopefully Mazda can sort it all out before all is lost for the 8. A trip to the auto mall near my buddy's house in Mississauga still reveals G35 coupes leaving the lot daily and RX-8s sitting for months (they had a MazdaSpeed blinged version that was there for over a year!) I'm thinking my friend would be better to pick up a new MX-5, in sort of a "this was the company icon then, this is the company icon today" way. (I'm still crunching the numbers to see if someday we can get a new Miata (I know, MX5, but who's counting) for my wife
)
Picus- impressive work on the Maranello, btw.

Derek, yes there were some temp differences but not quite that radical. In fact my better mileage days were on the days that were cooler. It's difficult to do a fair comparison because of so many variables but it is my honest opinion the higher octane was not beneficial either in performance or economy.
BTW, if you have nothing to do Sept 3 I'll be up in Berwick at a 5 mile road race -read running! starting at 9am.

Interesting about the fuel. Altitude- not much O2 in the mountains? The only other thing I can think of is this:
Octane, according to motorbike performance tuning articles I've read when I was racing, is only one index of fuel performance. Race gas, like VP, or Klotz, doesn't actually have incredibly high octane numbers- about the same as you can get at Sunoco, or just a smidge better. Volatility and burn consistency are some other examples of what's important. For example, if you shave your cylinder base to up compression, you need not only for it not to go bang once before the plug says so, but you need it to consistently not go bang before it's told to. Race gas is like this. The stuff at the pumps, not so much.
Some are better than others- the aforementioned Sunoco 94+ is reputedly amongst the best [Dear Sunoco, Please plunk down some gas stations in the Maritimes. Sincerely, ...]. We used to mix this half and half with race gas since the bike engines were not heavily leaned on (relative sense). The vicious cycle goes like this- bang at the wrong time increases combustion chamber temps, this causes more and more subsequent compression based ignitions, this causes more heat... tons more engine wear, often followed by an intimate discussion between piston and valves.
To get to it though, the point is that once the necessary octane for your engine is attained, having higher doesn't do anything. It's already not pinging. Not pinging is not pinging, kinda like being sorta pregnant, or not. It sounds like you were getting good gas in midgrade. I've always found the fuel in the US to be superior to most of ours (it comes from Canada, after all, whereas ours here in NS comes from Venezuala).
As for the Berwick race, just so happens I'm available that day as it currently stands, so I'm thinkin I'll cycle over and check it out. Some friends and I had planned a longer ride that day, and that'll make for around 80k, which is perfect. We'd just better not have a gale force wind in our face heading back home (alright, it's entirely likely, as you well know here in the valley)
Cheers,

^ Your second last paragraph pinned it although it was always hi test 91 used as well as the 94 super hi test sunoco.
Berwick is my debut race after a 6 months recovery. I'm still only about 75% healed and a bit tentative going in but need to get "race hardened" with a few tough efforts before the Chicago marathon. It's actually the Provincial championship race so all the fast folks will be out. I'l be around about an hour before and for a while afterward before heading off to a friends place.
