He has a "Giles" injection pump from Superior Injection which gives a whole 
lot more fuel.  Fuel makes boost.  Even with no smoke fueling on a stock pump 
my vanagon would easily hit 18 psi with the BOV and wastegate kept closed.  I 
am sure that 20+ with the K14 is not difficult to accomplish.  However, I 
believe it starts getting quite inefficient above 17 psi. Karl Mullendore said he 
managed to completely wear one out from fresh rebuild in like 3,000 miles 
running 23 psi.
