I have the A'PEXi item fitted (plus its complimentary 3bar MAP sensor) from the A'PEXi boost control kit.

I've only just realised that the BCS has been mounted with its VTA "NC" port facing upwards (rather than down, like the OEM 3-port). So if you imagine the BCS shown below rotated by 180 degrees...




Would that be detrimental to its performance - and therefore the turbo performance - when there's near max. duty cycle occurring? Or doesn't it matter?

 

Love the diagram.

 

Yeh

And I'm a graphic designer (well, of sorts).

That was an extremely quick (!tihs on) drawing I did for a member some years ago, enquiring what vac hoses went where.
