LSA CNC Race Ported Blower & Rebuild (Max Effort)

Shipping calculated at checkout.

The LSA CNC race blower port is max-effort CNC treatment on your 1.9L LSA supercharger followed by a by-hand round of inspection and final polishing. We rebuild parts of the LSA 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 LSA blower itself we do a CNC porting treatment on the stock LSA snout using the same proprietary epoxy process. Additionally, we port the LSA 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.

Our process for the blower porting includes:

  • LSA supercharger tear-down
  • Strip LSA supercharger of all bearings
  • Inspect bearings and blower case for flaws
  • Reconstruct the LSA blower case and snout
  • CNC port the LSA blower and CNC port the LSA snout
  • Perform manual ported LSA blower finish cleanup
  • Bathe LSA supercharger and snout in our Aqueous parts washer
  • Install new case and snout bearings
  • Install customers hub and pulley (or a new LSA pulley and hub can be purchased)
  • Fill rotor pack with new Eaton fluid
  • Install new manifold gaskets for a secure fit to your cylinder heads
