I've kept in touch with and glossed over the new car thread so perhaps I missed it but!

What are these engines doing? Other than managing HP between RC and Oval I've found little info. What is the rev limit? What is the boost? Are all engines treated equally? Is engine development frozen once the season starts? Are Lotus teams doomed for the rest of the year or will Indycar put a knee out for them? Is it all transparent or little man behind the curtain stuff?

A single link will suffice.

Thank you in advance.
