LRI 2" Blower Spacer for LS7 COPO Camaros fitted with 2.9L Whipple Superchargers.

  • $ 1,00000

The LRI blower spacer is designed to solve a couple of problems plagued by the 2.9L Whipple blower setup used in the LS7 format.   At the factory height, the heat exchanger underneath the supercharger consumes most of the available space offered by the blower tub.  This impinges the middle bank ports on the heads and creates a restriction.  

Elevating the blower and raising the heat exchanger increases the volume of the lower tub and unshrouds the ports.  This promotes a much better pathway to the combustion chamber resulting in increased power potential.  

Another benefit is the reduction of Intake Air Temperatures.  With the blower elevated the tendency to heat soak the heat exchanger underneath is reduced.

Our spacer is billet machined from 6061 aluminum and is designed as a drop-in part requiring only one small modification to the bypass valve linkage on the supercharger.  The linkage will need to be increased in length.

On the 2017 LS7 COPO Camaros, this spacer will still allow the factory hood to close.  Factory SS hoods likely won't clear.  VFN makes a supercharger glass hood for the Camaros.  It's not on their site, but if you call they can walk you through it.


This is a very specific application part that is expensive to produce.  They are built on a per order basis.  Please allow 2 weeks from the date of purchase for machine time and 3 to 4 days for shipping.
