I was going through the regulations this morning and I couldn't see any restriction on boost pressure. I don't think a specific turbo size has to be used either and a 1.6 at 15000rpm will produce plenty of exhaust gas and fuel flow isn't likely to be a big restriction either.
Given this, what is stopping the creation of 1000+ bhp engines for 2014?
