Roush Saleen S/C ?

Great question...I would like to know that too.

It runs through just the intake manifold. The only liquid in the actual supercharger is the snout oil, which shouldnt leak out under any conditions.

EDIT: On a side note, be very careful not to damage the vacuum control housing located about midway down on the drivers side of the supercharger. It should have a big yellow or orange warning decal not to mess with it because it is tuned from the factory, but sometimes this falls off.

Good luck!
