Trying to reach boost by 3k and pull to 8k is a sizable task.

Did SW know you are going w a turbo on you R case? We are talking a lot more heat and potently expansion. Having said that there has been one builder I read about the built a 2.7 twin turbo he used to drag race that made big HP w/o a problem. Road Racing might be different.

Best of luck and look forward to the project.
This motor is a change of direction, so wasn't factored when I built the case. In talking to him later, he didn't feel it would be an issue, so have decided to move forward. I am still tryin to tease out all of the particulars in this regard, but all looks to be OK as long as I'm not greedy.

I assume managing the variable vanes is through electromechanical control, not by pure mechanics (like a bypass). I will have to research the ECU capabilities more to confirm that this isn't beyond my capabilities - I am not so skilled as to write custom code for vane actuation.
