Re: Hood Motors
You're getting some great capacity specific power outputs but efficiency is not very good. Also your torque curves on your turbo engines really shoot up around 3000RPM which may be a bit late, especially on smaller engines that will provide small amounts of torque before the turbo kicks in making pulling away quickly or darting around town conditions feel slow. Try a smaller turbo and not much more than about 110-120HP per liter (Around 180HP in 1.6). This will also improve efficiency.
Looks like a great range of engines you have there! Just experiment and see what you can do

Re: Hood Motors
Good efforts. Most of your engines in their current state are in a relatively de-tund state, you can see that most of their octane ratings are in their 80s. You can safely tune the engines right up to the desired octane fuel you are using and you should see gains all round.
