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.
