Blow Off Valve Upgrade Kit RX7 FD

Blow Off Valve Upgrade Kit RX7 FD

The Pettit Racing Blow Off Valve Upgrade Kit is one of our top selling upgrades for the twin turbo RX7 FD. The 1" ports are twice the size of the stock valve which It's a direct bolt-on replacement, and installs in under 30 minutes.

Most original plastic valves are really old and typically no longer work properly, over time heat cycles and normal use cause the diaphragm to harden, which impairs both valve operation and response time. 

Our upgraded Blow Off Valve is completely CNC machined from billet aluminum, utilizing dual o-rings to seal the piston (no diaphragm to fail like the stock part). Finished in black hard anodizing. Lifetime Warranty.

Our BOV is calibrated for turbo rotary engines and provides twice the flow volumn of the original part. 

Benefits include:

  • Better surge protection
  • Reduced thrust loading
  • Improves boost response time
  • Keeps your turbos spooled between shifts
  • Provides 50% or more flow than OEM
