Just wondering if you turbo gear heads have seen this

yeah dude thats now stock on the new VW/AUDI 2.0T block.
i think its pretty sweet.

[kccb7]

i think new ford powerstrokes have them too

[flacopower]

that is awesome! i bet it would cost an arm and a leg to buy a turbo with that technology

i believe the vw turbos cost 1200 $ new

[kccb7]

i wonder if these would effect tuning. harder or easier?

[AsheCb7]

as far as tuning goes its not easy cuz you need something to control the vane manipulation and yes the new vw and old powerstrokes use this its amazing technology but it is harder to tune till you figure out how your gonna make the boost maps for the turbo goes but if you want a real heads up talk to gale banks cuz hes cracked this thing and hes got it down to a tee and at the moment all the diesels are using it except for dodge and he makes a kit i didnt know it as VNT i knew it as VGT (variable geometry turbo) when i was inschool me and my teacher were tossing around ideas for the vane controller and gale banks was cool about it and theres also alot of stuff on the net about it well we aint figured it out

scary...whats even more scary is a price is not listed at all on the website

That's a really good idea, but I bet it would be a pain in the ass to tune it.

It would be harder to tune, but the basics are pretty simple. The vane apperature would be small at low RPMs and get bigger with engine speed. Banks loves to use these turbos on their Sidewinder Kits, and I saw an NSX that Corky Bell built way back in the day that used them. Great for low lag, while still allowing great flow.

This technology has been used in jet engines for many decades now.

yea . . . he used the aerodyne turbo right?

[Punkrampant]

Nice. No lag

[kccb7]

they should control them with engine vac.

[Fearit22]

Yeah, I was thinking that this is kind of a similar idea to the dual runner intake manifolds. They are controlled by the vacuum so that they open and close and the right times so I would think they could do it with the turbo.

[owequitit]

I can't remember if he used the Aerodyne or not, I just remember that it was a badass NSX. It was featured in Turbo magazine in like 98 or 99.

As far as using vacuum to control the turbine vanes, it would not be nearly precise enough. The problem with vacuum is this: when the throttle is closed, it is all the way on. When it is opened, it is all the way off. About half throttle or so, you start to lose vacuum very rapidly. Depending on throttle positions, engine speeds loads etc, the nozzles need to be VERY precisely controlled. This entails some kind of electronic solenoid, run by something with quite a bit of computing power, that is not dependent on something as uncontrollable as vacuum.
