What kind of serious hp are you looking for out of the LNF?
Those cores and the whole intercooling system in the LSJs are designed and manufactured by Laminova, a division of Opcon which owns Lysholm and they develop some of the best superchargers in the world.
There is a Saturn ION RL that has well over 450whp that is doing perfectly fine on the stock intercooler system.
Do you have pictures of the core(s) in your system? The Laminova cores are pretty advanced...
Laminova Production AB If you click on "intercoolers" on the bottom right, there is a pdf to open on the new page. With the 4 cores in the LSJ manifold, you could convert the system to a dual pass also so the coolant isn't staying in the intake manifold too long.
