"The F1 turbo engine is on the horizon! It's back!" That is what the majority of the world will say anyway. Not so. Turbo-compounding is the reality and it is far far far different than you might imagine, and I find the knowledge I seek is beyond my big brain. (more after J)

You see, the Turbo is a Schizophrenic. It's a normal turbo yes, but also gearboxed back to the engine to recover even more power. Sounds fine to me. I understand that, and I learned that in flight school in general engineering knowledge classes, but in trying to figure out how they would design it to work efficiently for maximum performance applications, well I found myself getting buried in what I can only describe as black science from some real life rocket surgeons over on F1technical.net. By page 18 of their forum I felt like that guy at a party of doctors talking shop. "I know how to tie shoe laces! That's like Intestinal repair isn't it?"

Pioneered just after WW2, Napier built the first turbine recovery unit onto a 2-stroke diesel and recovered about 6-7%. Present day recovery is a bit over 30% efficiency and you can find that on modern large commercial Diesel engines. But for F1? How will it really work and how can we understand it? Well I found someones research paper published here. It it it starts from the beginning and tries to walk us all through to the end realization of the F1 power unit for 2014. enjoy. I hope we can make real deep sense of it like I'm just starting to.
