Chris,
One of the misconceptions that is in this thread is that streamliners operate with laminar flow. If you calculate the Reynolds number for a car moving at 350 mph and one foot back from the nose it is 19.4 x 10(to the 7 power) ( 194000000) which is way beyond the transition point value for laminar to turbulent flow. The stardard calculation for the Re is: Re= (air density)(velocity)(length)/viscosity. If you use calculate it at STP (Standard Temperature and Pressure) and use English dimensions it simplifies to: Re= 6300(Velocity ft/sec)(lenght ft). If you use this formula you can see that the Re quickly exceeds 1,000,000 within the first .06 inches of the body length.
Some things can affect the position of the transition zone, and one is the shape of the body, if the pressure gradient is negative it can assist in keeping the boundry layer thin and extend the length of the laminar flow region, which is the lowest drag regime. This is why using such shapes as the NACA 66000 shapes is good as these were designed specifically to have extended areas of laminar flow. I am not sure if suction would cause a turbulent flow regime to become laminar again. Probably a good question for "Blue".
