richard,

i'm looking to go speed density and run the hfs4 on my 08 wrx. i was wondering when folks are running meth/water with a fmic where the IAT and jets are placed.

typically you want the jets as close to the outlet of the core as possible.

but i believe it has also been advised that you want the IAT sensor prior to the jets spraying water/meth and ideally in the intake manifold.

do you have any subarus or setups in general running speed density and could perhaps comment on the optimal setup given my application?

thanks!
