Adrian, I just ordered a Mpx4250ap for myself, I should say backordered 
it  @$22.62 US.  It seems to be the MAP of choice, I will be running 
12psig boost or 1.8 bar absolute.  I can run up to 3 bar absolute with 
that setup, or so I hear.  I also might have a line on half a diesel 
truck intercooler.  With a littel welding I might have a BIG intake 
charge cooler.  That's still in the works.



Thanks for the input,
