Turbo is great, just the damm lag and the heat load. And with just one turbo the drivebility is not so great on race applications. It more or less on/off. Softer power output by having two turbos.
Instead of useing Eaton, maeby you could use twin screw like Kenne bell, then build intake to house four Laminova intercoolers.

They are simply the best IC in the world.
I builded a big Hemi with a KB twin screw, blower factory told us that intercooler is not needed else than marine and tractorpulling applications.
But there is nothng wrong get your intake air temp down..
I'm currently playing with idea to build for laminova IC intake to my twin screw V10.
