Replacing I/C with WI - Need Help Please!

Paxton NOVI2000 Blower
405 WHP / 285 WTQ @ 10.5 psi

I am currently running a Spearco core air to water I/C that is deffinately too small and I am out of room to go larger. AITs are hitting 150-160 F under full boost at redline and I am measuring 4-5 psi of pressure drop through the I/C.

I would love to yank out the I/C and replace with a WI system run by my standalone management using a custom AIT and boost map. Pulling the I/C should yield 15 psi of boost at the manifold. I could also pulley down a bit to 12 or 13 psi for safety.

Is this a good idea? Anyone have any first hand experience replacing the I/C with WI. I usually cruise the car 90% of the time anyways and run up into boost only at the track and occasional light to light races.

Thanks in advance for your input and design ideas.
