I am starting a project for school where i need to reasearch a solution to a problem and think of a way to implement it in the fiel d of Engineering (which i am studying).
I chose Variable geometry Turbos (VGT), as in the (997) 911 turbo, over regular turbos. The problems were were high boost threshold and turbo lag, and these are supposed to be much improved by VGT.
Now, My problem is, since VGT is fairly new technology, and my university has the crappiest library ive ever seen i canot find any books one VGT.
So I come to you, in search of help.
I need Any kind of information you can find on VGT. Simply post the link or tell me about what you know. I have done some searching and found some very good articles on the SAE website but I think i need to buy them to see them in full.ANY help is appreciated.
Please post relieble sources,(nevermind to wiki-it) for i will need to quote them if i use them. Unreliable sources are also welcome since i have to learn as much about this as possible.
Thank You in advance.
