1.5L/90ci Blower On A Slant

People with the melted pistons were usually from Lightnings and 03-04 Cobras with the back left bank cylinders 7&8 because the air coming out of the blower was overtemped (because the blower is overpullied) and the intercooler loses efficiency on that corner-it's the last part of the intercooler before the coolant exits to have the heat exchanged.

So, you have overheated compressed intake air charge not being cooled by the intercooler and now being compressed further by the engine-makes for exceeded limits. Then it's time to upgrade :)
