The idea of using water into the exhaust upstream of the turbine sounds like 
a really good idea for reducing turbo spool up times.  I am definitely going 
to research this more for my current project ( 
http://www.j00tel.net/turbo_ek1 ).

An idea that we had to reduce turbo spool time was this, kinda/sorta a 
pseudo-VNT idea...

Using a split turbine housing, build a throttle body which allows us to 
select either one side of the turbine housing, both sides of the turbine 
housing or a varying degree in between.  This should let us vary our turbine 
A/R and thus control spool up times.  We would control the throttle body 
using our custom ECU and a table, something like RPM vs % throttle body 
open.

The details are yet to be worked out but this is the basic idea.

Is there a more approrpriate place to be discussing turbocharging ideas?  If 
there were a DIY turbo list similar in activity to this list, that would be 
great.
