• Constructed from high-grade billet aluminum (6000 series), lightweight and durable

• Over 330 CFM of airflow through a 2.0″ (50 mm) inlet, CFD-optimized design

• 50% lighter and 25% more compact than rival BOVs in its class

• MILSPEC hard anodized guide and piston, high-temp silicone-Nomex diaphragm

• Dual 1/8″ NPT reference ports, pre-installed Blue spring rated for −18 to −14 inHg

• Supplied with weld-on flange, V-band clamp, vacuum fittings, and Turbosmart decal

• Suitable for high-performance and race applications, handles up to ~8 bar of boost

• Compact design allows fitment in tight engine bays, preferred over Tial valves in many setups

Compatible With:

• High-power turbocharged gasoline engines (street or race use)

• Vehicles with aftermarket turbo kits, including:

  • Toyota Supra (MK3, MK4, MK5)

  • Nissan 200SX / Silvia (S13-S15) / GT-R

  • Subaru WRX / STI

  • Mitsubishi Lancer Evolution (all gens)

  • VW Golf GTI/R (with turbo upgrades)

  • Audi S3, RS3, TTRS (with tuned setups)

  • BMW M2/M3/M4 (N54, N55, S55, B58)

  • Ford Focus ST/RS, Mustang EcoBoost

  • MazdaSpeed3 / 6 / RX-7 turbo builds

  • Honda Civic Type R (with turbo mods)

  • Any engine swaps or builds using 2JZ, K20T, LS-Turbo, etc.

⚙️ Technical Requirements

• Sufficient engine bay space — this is a large 50 mm BOV (compact by RacePort standards, but larger than OEM valves)

• Must have a turbo/intercooler charge pipe where the flange can be welded or adapted (V-band or 50 mm inlet)

• Requires a vacuum source to operate the piston

• Some setups require custom fabrication (modifying pipes, installing a flange, tuning the ECU)

🚫 Not Suitable For:

• Naturally aspirated engines (no turbo)

• Cars with stock setups only

• Tight engine bays with no room for large BOVs

• MAF-based engines without proper tuning, since the RacePort vents to atmosphere and may cause issues if uncalibrated
