Split intercooler - upgrade opportunity?!
For a few months now the Spider has been making a slight hissing/ creaking sound under boost which was baffling me.
John at MVC has just fitted a replacement clutch and flywheel for me and noticed an oil leak whilst working on the car.
Turns out the intercooler is split, which is causing the hissing sound under load.
Given that the replacement Alfa part will likely be expensive, I may as well replace it with an upgraded FMIC if possible.
Not done this before so can anyone point me in the direction of a good upgraded unit? I know that James put one on his Brera a while back.
As I understand it, the split is essentially acting as a boost leak, so replacing the unit might restore a few missing horses, but IIRC the gain from upgrading your intercooler is more regarding smoothness and consistency of boost, rather than much of a power increase.
Would welcome your input guys.
Luck is the residue of opportunity and design...
