Increase your supercharger whine AND enhance the look of your engine bay with these billet aluminum LT4 lids by MPI!
This lid reuses OEM gaskets and can be easily swapped out in less than 15 minutes on your car.
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!
