Before we give you the run-down on this supercharger port we'd like to point out a few things about our ported blowers in general:
The LT4 CNC race blower port is max-effort CNC treatment on your 1.7L LT4 blower followed by a by-hand round of inspection and final polishing. We rebuild parts of the LT4 blower case with a proprietary epoxy process to actually expand the space within the ported blower to allow for more air throughput.
Beyond porting the LT4 blower itself we do a CNC porting treatment on the stock LT4 snout using the same proprietary epoxy process. Additionally, we port the LT4 snout to create a profile that easily accepts a 102mm/103mm throttle body.
Attention is paid to the case as we play with rotor timing to help setups with large cams and large air volume requirements. This upgrade typically picks up 70 - 90WHP on your "typical" build but its not uncommon for a radical setup to pick up 80-120WHP.
