Rich, I wouldn't have thought that a 6mm (1/4") drain would have caused a measureable loss in ram pressure. The ram pressure is a f(speed & air flow) and as the amount of lost air through the drain is directly proportional to the X-sectional area of the drain compared to the intake the loss will be very small. Besides, there will be a much greater loss as soon as you open the throttle!
You could of course work out the volume of air passing through the engine at the ram pressure and then through the drain at the same pressure to see the comparison
