I am a Corporate Pilot and CFII that has been flying Brooks Lemon’s Christen Eagle for the last year. Brooks has recently installed Rod Bower’s Ram Air system and it appears very well engineered with a lot of attention to quality control.
Local flights and low level training are done with the filtered air system activated but when extra power is needed the Ram Air provides an extra inch of MP. At normal power settings of 26” and 2500 rpm I will see an increase of 1” MP and you can really feel the extra boost when the Ram Air valve is activated. Normal cruise at 24” and 2300 pm will provide 140 MPH.
If I was to give this product a score for power and quality I would give it a 10.
