Makes some interesting reading this.

Oh yeah, VARIABLE VANES.

 

[DarthPalmer]

Can't see a link?

 

[General Banter]

Theres no link, it's pictures!

 

[ru']

If all the pictures are supposed to be red x's, then it's working fine here.

If not...

 

[General Banter]

Dammit. I'll sort it in a bit

 

[General Banter]

Fixed :bigthumb:

 

[buffy]

how cool is that !!! should sort out any lag probems associated with the larger turbo's and it could make a smaller turbo flow more air as well
great idea,

 

[MrScottish]

Very interesting reading!

variable vanes isnt new,just mega expensive,and as for the electric bit it seems all that will do is add an extra trickle charge to the battery from waste gasses,very gimmiky

 

[iansr33]

isnt this what porsche already fit to there new cars

I thought that too, but the wording contradicts it. 'Electrically assisted' isn't 'Electrically beneficial'

I suspect that what they mean re the electrically assisted bit may be as follows, approximately..

When the engine speed/rpm is not commensurate with a sudden demand for more power, so the turbo would not normally spool up well, spooling would be assisted using an electric motor. I would guess this to be integrated into the generator mounted on the main turbo shaft, it being a sort of two way input/output device.

Essentially an electric motor is a generator, so you'd only need one device.

Problem with using it as a motor to spin up the turbo is you'd need hundreds of amps.

When cars have 40V plus electrical systems this will be easier to 'get hold of', but it may cause us a problem in our skylines...

Don't forget that all this stuff about greater economy etc. is just as applicable to greater power too...

I remember once at the shelsley Walsh hillclimb in worcestershire there was a car ("shelsley special" - a complete one off with no bodywork) there that used a helicopter starter motor to keep the turbo spinning. Mad idea but seeing it in action was pretty cool. The intention was to use it as a crude form of anti-lag. For the most part it worked well.
