[s-cars] Subaru Intercooler question - Add a fan?

[Joe Pizzimenti]

And tons more weight above the center of gravity.

Leaded fuel has no such downsides and it's foolproof.  I may be a bit biased
since I've been through the dead water injection pump and have the head
gasket to prove it, but messing around with tuning for an assumed intake
temp drop is higher risk than just going with a front mount intercooler and
putting good gas in the car to begin with.
