Whipple. FAILS there...saying that you don't need an intercooler with a Twin Screw blower...proven, especially with the W140AX on a 3800 platform...that thing made SO MUCH heat...you couldn't run with with anything smaller than a 4.0" pulley without an IC, S3IC to be exact...and he ended up running a just a 3.75" or a 3.5" since anything smaller was brutal on knock.
