not sure if it would help or not, two reasons i say this,
one, air to water more efficient.
two, you will be creating a harder path for the air to travel, thus possibly hurting air flow from the supercharger to the motor.
also on a dyno it might not show all the gains cause air will not be flowing across the heat exchanger with the truck just sitting there.
might be a tubing nightmare also, on a vortech type setup, that is mounted where the accessories are, the intercooler is where the boosted air is, with your setup u can only cool the ambient air before the blower and that wont help performance to cool..
just my thoughts, only real way is to try though..

thats what I thought. didnt know if there is any performance gain or not. I would think if you add more boost, like maybe a 6 or 10 lb lower pully it might be somthing to consider. Just wondering if anyone on this board has ever messed with that setup.

I spoke with some of my Turbo Buick friends, and they had mixed reactions about air-to-air intercooling on low boost level applications. Funny thing is, that ALL of them that run high boost pressures (20-25+ lbs) have air to air rigs. Most of them are from Kenne Bell. The ATI procharger uses an air to air set up, too.
It would be interesting to see a comparison.

From what I have seen / heard the factory liquid / air unit is pretty good. It can be improved for track use by supercooling the liquid with ice or could simply be improved upon by adding a larger front mounted heat exchanger (radiator) and fan. The problem with running a front mont with the L's blower configuration would be lag from the extra tubing involved which would reduce the Eaton's effectiveness as a blower in my opinon.
One alternative would be to run a large Vortech / Paxton / Procharger / ect with a large front mount intercooler and really make some power. This was done back in 99 on a new L and the truck woke up quite a bit, unfortunetly the trucks owner wouldn't go for the high stall speed convertor needed to make up for the loss of the Eaton's awesome lowend punch. At this level a built bottom end, high stall torque convertor, and custom intake would be required but you would be flying and what the heck you might as well slap a turbo on in place of the blower and really have some fun.
