No worries. We obviously talking about different things.
I still maintain that a free flowing exhaust is the best dollar for dollar way to gain power. Of course, replacing the exhaust does create a possibility for the computer to get angry. The computer has sensors on the exhaust system that monitor air to determine if the fuel mixture is too rich or lean.
I won't be monkeying with any of that stuff though. My gas mileage mods simply involve keeping air in the tires, regular maintenance, and an occasional Techron treatment.

You could replace your catalytic converter with a high-flow catalytic converter or none at all... You would have to retune the ECU. An ECU tune alone could give you better fuel consumption. You could also have the tune correct the CVT to stay in a lower ratio while you drive. You could change the fuel cutoff point. Along with some real skinny tires and more Aero for your vehicle you could probably achieve some better results but if you're going for economy you're going to lose power that's just the trade-off you're going to find if you start messing with the engine.
This thing already gets really good gas mileage though so unless you're planning a cross-country race where the lowest fuel consumption wins I don't really see any point as your gas savings will never equal the amount of money you're putting into it to achieve those results.

Once you narrowed down the size you want, you can check out alibaba.com and find a cheap supplier. The ones mentioned in the videos, their price got jacked up quite a bit once they became popular.
Alright, lets get back to this project. Last I left it, I had fried my dc-dc converter. It can only handle 18V for 100ms, and is really only meant to handle 13.2V which is kind of low. When the alternator kicks on, it boots the voltage up to 14.4V. When you switch it back to the dc-dc converter, that is simply too high and it will eventually fry as mine did. This simply won't work for the next phase of this project. So, we have to revisit the design and make things a bit more robust.
This is what we started with:
This is what we're now going to. I've added a 7805 linear voltage regulator before the dc-dc converter. This linear voltage regulator will take 7-35V and convert it down to a regulated 5V. So, a voltage spike of 14.4V is nothing for this puppy to handle. It then spits out 5V to the new dc-dc convter which converts 5V to 15V. The old one took 12V and converted to 15V. This design will be a lot more robust and should really never have issues with frying components, yay!

Slightly off topic, but have you considered trying to see if any one way clutches would fit the Mirage alternator? They've been around for a while and there might be something that'd fit. Wouldn't be able to get any kind of regen braking if you did though.
