The tricks up my sleeve... Methods I may implement for better FE.

[DrivenByNothing]

The ECU will receive a modified voltage from the O2 sensor in order to lean out during closed loop operation. Detonation is obviously a realistic problem. To combat this, I will be implementing water injection. Water injection is very effective at preventing detonation and has several other benefits.

Water Injection Benefits:
Raises octane of the mixtue
Increases compression (water is incompressible)
Cools incoming air
Steam cleans cylinders

I'm sure I'm missing some. Water injection is much easier to implement on a turbocharged engine.

Another reason for the turbo, is to allow for higher compression to be created in the motor in order to test E85.

So the reasons for boosting are a) Ease of implementation of water injection b) Ease of creating a higher air to fuel ratio, c) Gain of some extra power for a small displacement engine, and d) Increasing of compression for alternative fuel applications.

If it doesn't work out, most of my investment will still have progressed me forward.
