So what is the bottom line Jeff. What trim and A/R do I use to get
to 35K?

Paul Lamar

You definitely use the big turbine (P) and a big A/R.  I've not looked at
the whole thing to pick the right turbo for you.  

 Run the model (it has a 1.49 P turbine) and try
out the different compressor options.  You'll need a wastegate or a
throttle.  Use the leak model with zero leak area to try the throttle
approach.  I still think you should run the monolithic exhaust with a
controllable throttle if the 35K is just a stunt.  After the stunt is done
cut a hole in the turbine housing and never worry about it again.

Where does the hole go? Perhaps between the scroll and the exducer?
How large of a hole?

Please print this drwaing and mark the hole position
and then email or mail it back to us.
