Now Many have try many different things, but this is i believe to be the most cost effective way to build a no lag turbo system. It is based on a design, by Nick Mann. Well I was working in the aerospace industry, I learned of a car racer that was using a Helicopter Gas Turbine APU (Auxiliary Power Unit) to power his race car, as he worked in the aerospace industry. After Much research I found out it was Nick Mann and his "Mannic Beattie" , an AWD hill climb monster. You can find More Information on this car at http://raceenginedesign.co.uk/the-manic-beattie/

So Now that I got you all excited about that car porn.... I can tell you, how to do this for CHEAP, and have the same benefits....
You are probably saying to yourself, I can't afford a APU, "if you know what these cost and got the loot, good luck on getting one....
I have an alternative Idea. How about turning a turbo into a gas powered turbine yourself, it cheap, easy, and you don't need much believe it or not!
First yoiu have to understand how Turbines work. This should help.
Basically a Turbo works almost the same as a typical turbine engine, it is just missing a combustion chamber. so we have to add that!
It will loook something like this!
Now how is this going to help us, well, now you have a turbine! We will use this in order to power our turbocharger now!
And Now Some Silly Jet DIY Video
Now there is no reason, we cannot apply the same idea from a small turbo turned turbine, feeding a larger turbo and creating a no lag boost system as it is running as an APU.
NO LAG.
I personally Would love to build these and install it on a v8 in a little car and spend the rest of the money on suspension and enter into the Grassroots Motorsports Challange
IT WOULD BE A MONSTER!!!!!!!!!!!!!!
Largest challenge is most likely controlling the turbine as well as output boost, but i imagine that could be simply overcome from a arduino controller and a few simple solenoids and pressure sensors
