LT4 supercharger lid/cover specs:

We offer these lids in custom powder coat colors as well as anodized finish- And can even do a custom laser etching if desired! This lid design entails minimal interference on the underside, thus allowing more air to go in the same direction. Power gains resulted in +11 RWHP and +14 RWTQ on a Hole Shot Mustang Dyno on an otherwise stock motor and stock tune in a 2017 Corvette Z06. The boost is available quicker and is more consistent through the power band.

This lid made an increase in about .25-.5 lbs. of boost. The lid generates better flow and causes more knock detection on the stock tune which results in ~1 degree of timing retard and power back. Finally, the additional whine of the blower is intoxicating!
