next 911 turbo to use 'variable turbine geometry'

[chrishill 0]

apparently this is a bit like variable valve timing, only it adjusts the blades on the turbine and gives the same effect as having a twin turbo setup. its not new technology, but its new to petrol based cars.

was going to say I'm sure VW's have this already, but the article refers to it, TDI's have had this for a while, didn't know it wasn't being used on petrols yet though, helps with the removal of turbo lag.

yeah, i doubt its going to hike the power up to something insane, but its an interesting bit of technology, and reducing lag is always a good thing!

 

I think diesel trucks have had these for a while too.

Nice, I think the technology is also referred to as a progressive turbo?

I guess it probably could be used to hike the power up, as you could use a bigger badder turbo without any of the usually-associated downfalls :)

possibly, i suppose they could get away with a huge blower with very little spool up time using a VTG, but my guess is they'll just make a car with insane torque all through the rev range.

 

now, a twin VTG turbo would be fun...

Yep, I agree. If they put one out with a huge driveable turbo on it with the potential for massive power, they'll kill off all their own aftermarket tuners!
