Variable Vane Turbo (gif) - BMW Forum

///M Power · 09-26-2006, 08:10 PM

For thsoe who dont necessarily understand what variable "vanes" in a turbocharger are....here's a nice little .gif animation

Notice the "vanes" around the wheel. They change direction to change flow characteristics of air as they enter the wheel.

You guys will see this technology in the new 997 turbo (and my car

)

What turbo are you getting?

For those people who can't make up their mind on how much boost they want?

That's the type of turbo I have in my car already. Although mine's kinda small and probably maxes out boost at 12 psi due to aforementioned vanes.

No.... The major purpose of this tech. is to let the turbo act like a small trim at low RPM so as to build boost early in the RPM range and then once the CFM's and EGT's get up in the exhaust stream it can change to a larger trim type for more CFM's at high RPM. Acts like a small turbo when needed and then a big turbo when necessary. It helps to eliminate most of the "lag" traditionally associated with larger turbos.B)

What model is it?

///M Power · 09-27-2006, 01:24 PM

Don't have very man specifics on it. Just kind of wish it was larger though. Ill probably max out at 14 psi. Unfortunately the company that used to make them had their owner die, which is why they shut down. It's friggen impossibel to find info on it specifically.

Looks like an Aerodyne aerocharger. I had one on my 2002tii which I bought from Korman (really from Cartech/Corky Bell). After the sixth one broke, Aerodyne refused to give me another... Car was very fast but didn't last! Bearings failed, vane controller broke, oil fried and turned black, etc. etc. It is still lying around in my garage somewhere.

got any pics of the 2002tii? A buddy of mine got me interested in them awhile back. He's got a Nevada (round tail) and a white one (square tail I think). The Nevada is one of his semi-daily drivers (he's a mechanic so he has several "daily" drivers).

very nice! Don't care much for the hatchback look, but still a tii is an awesome car.

One of the guys that works for my friend got a E30 325i motor into his 02. Granted, there's no front support for the cars nose any more, so if he hits anything it's gonna be destroyed... but it's a fast little guy.

I'll try to find some pics I posted a while back of some of the coolest 02's I've seen.... mostly from a Vintage BMW show we go to in Winston Salem.

Thats strange. I can see how the oil turned black. Never had a problem with mine. How many miles did you have before it broke? Did you service it by recommendations?
