boost hoses

No, it does not have an effect, remember, it is flow that makes power, not 
boost.  A little swelling of the hoses will not affect flow, and 
realistically, will not reduce pressure either (theoretically it does, but 
may not even be measurable within' reasonable tolerances).  

A common mistake many make is thinking that boost (how many psi the turbo is 
producing) makes power.  It is flow, or how much net _air at a certain 
pressure_ is being fed into the combustion chamber.  Two turbos, a K24 and 
K26 can be making 15psi for example, but the K26 will be flowing considerably 
more air.  Of course, temp (turbo efficiency) plays into this, as do other 

Pressure alone gives no indication to how much air is actually flowing into 
the motor.  Anyway, end of rant  ;)

 Watching them rev the engine at idle, I noticed the blue silicone turbo
 hoses visibly growing. Pretty impressive...but I wondered if some of that
 boost was going to waste...
