[s-cars] MAF to intake side of turbo

[Kirby Smith]

Downstream of the turbo there can be pressure waves, particularly if the 
bypass valve doesn't work perfectly.  These might test the MAF heater 
wires' strength.  Maybe worth an experiment; the wires "probably" won't 
damage the valve seats if they break off.
