    so the air bounces off the head and back into the blower.

    wouldnt porting the supercharger then not doing the lim just bounce the air off the lower in the areas where the supercharged port is opened up more?

    no.

    Unless you go crazy with your port like I did.

    But is there any benefit to that? Who knows. Probably not at our power levels.

    Port match the LIM then.

    Opening up the top of the LIM for the intercooler probably has no impact on power flow and all that crap. The blower forces most of its air out the back. I don't see how the air is going to magically divert back away from where its flowing with nothing to force it over there.

    Basically in a nutshell...

    Will it hurt? No.

    Will it help? Not enough to make a difference either way.
