I'm sure a few of you have seen this....I know I came across it, but I didn't read it.

Read it over....makes you feel pretty damn good about the heritage that we are about to join.

Alright....tech tidbit from the paper......

We've all heard that the exhaust valves are sodium filled. Did anyone know why?? Check this....

"Under high temperatures (above 280F), the sodium melts and splashes up and down in the stem, absorbing head from the valve head and tranferring it to the cooler stem, where it is dissipated into the valve guide and cylinder head."

Woah......

It was pointed out as being a cool article over at NASIOC.....but I"ve seen it over here for a while......

http://media.subaru.com/

Go there and then click on Impreza on the side....NOT on the STi pic above. The links are to the right by the STi picture. This article is "Core Technology"

Been there...

Nice article, thanks for pointing it out. One that I've had for a while is the STI Technical Description from Australia, which I found online here:

http://www.wrxhawaii.com/misc/Impreza WRX STi Technical Description.pdf

It has a lot of the same info, but in far greater detail. The problem is that it is all about the 2002 Australian STi, which obviously isn't exactly what we're getting. Still, a lot of the items are surprisingly similar, including the intercooler sizes, the clutch pressures, AVCS, etc. The Australian document just goes into more detail and has pictures and graphs. Maybe they'll get around to doing something similar for our final non-draft version.

Nice description of the sodium filled exhaust valves. The other document has pictures of them, including how they fit in the engine, but doesn't bother to explain how they're used as a heat pipe.

Another difference is that the '02 Australian STi seems to have Suretrac LSD for both front and rear, while ours comes with a clutch-type mechanical in the rear. Our document seems to imply this is a good thing (and certainly better than the viscous rear from the WRX, and thank goodness for any front LSD). We also get the trick DCCD-A.

Sweet article......Just makes me want this car more and more. You know, the more I keep reading about Subaru the more it sounds like I will never buy another brand of car!!

Ya know, statistics show that 85% of all previous Subie owners won't consider anything else the next time they buy a car.


Also, that article is the VERY reason that I wouldn't buy a Mitsu. I wanna see Mitsu come out with some dedication to their customers like that.

Awesome article, thanks for the link!

Reminds me of the Saab commercial where it states. "Those who test drive a Saab usually buy one."

That is an AMAZING number. I'm very ready to become a proud and long term Subaru owner.

Ya know...on one hand you want Subaru to become popular and more recognized, but on the other, it's like having our own little family of people who really know what a car should be like.

FYI, sodium filled valves have been around in turbocharged cars for a long time, notably on the 944 Turbo from the 1980s, and are also commonly used in very large displacement American V8s.
