On the intakes idea, has anyone thought about using a home made metal fan and electric motor for 1) forced air induced design, and 2) a colder air to be forced through the whole engine. You could hook it to only turn on and off right before say 1/4 throttle with a "Dimmer switch" in your throttle assembly making it fully adjustable to the air needed to be forced through. I feel honestly that in doing this, you could maximize speed, rpm, bottom end, torque and overall heat of the whole engine plus be in essence better than a ram forced air inducted hood scoop and would also add about 1.5"-2" to your intake.
