Variable Geometry turbo?
Variable Geometry turbo? what do you turbo experts think about bank's turbo new turbo design, surpose to be the best of both worlds(spool quick like a small turbo but flow like a big turbo on the top side)
I saw that also and it looks like an awesome idea.
If anyone didn't see the show, I'll try to explain how it works. Basically it's a regular turbo except in the exhaust turbine side, there are "fins". What these fins do is move in an out of the exhaust path to increase the velocity of the exhaust moving through the turbo and also forces more of the exhaust gases to actually push the turbine instead of going around and out. The fins of the turbo are controlled by a mircoprosessor that considers throttle position, boost, load, etc... So if you gun it at low RPM's the fins will open up to help spool the turbo, then gradually close as the turbo spools. They say it virtually eliminates turbo lag. I am not sure how difficult it will be to bolt one of these onto our cars, and I'm sure they cost a lot also. Very cool design though.

What show? but I know about this turbo, if you are refering to the Holset HY55 that they used on their cummins dakota to go 222+ at bonniville, i've been tracking that tech for the last two years now. Pretty hot ****.

I have a friend who has worked on these turbos for over 3 years, trying to adapt it to his Cummins diesel Dodge. Those suckers are super expensive, and break your heart when you huff one. The results he got were impresive, and he did hand control it for a while with a rotor ****.
The Ford diesels are currently using something simiular, as are the Chevy's. The current Cummins engine found in the Dodge (ISBe) is using a VGT turbo in other applications, but is not using it in the Dodge trucks. Also the software to control the turbo is not built into the Dodge ECM as it is in those other applications from what I hear.

The International VT365 ( also used in Ford trucks, and passed off as a Ford engine ) uses this technology. They are a great idea and work excellently when they work. Unfortunately we have been replacing them at the International dealership that I work at between 3-5000 miles. They have been nothing but trouble in virtually every single case. Very much a case of a technology that is not ready for primetime

You sure you aren't thinking of VNT? Variable nosel tech. Very different for VGT. I know Garrett has been experimenting with it too.
BTW, WHAT SHOW?

VNT has been around for ages...VGT is different. VGT actually has a turbine blade that is designed with fins that slide axilly along the turbing blades...VNT varries the turbine housing size around the blades. You're right...same goal, different ways to reach it.
i think areoquip (or some brand that starts with areo*) devolop somthing like that first. was the vats turbo, though this sounds a little different
pretty intersting, i think maybe ten years later they would have fixed the relibilty issue
