So how much more can you do with a blow-off valve? Well, the Deceptor Pro II takes the ‘Respons’ concept even further...

• Remote proportional venting bias/volume control- from silent to loud or anywhere in between
• Sleek, compact in-car BOV volume controller with backlit dial
• End point adjustment to control maximum vent to atmosphere bias setting
• Volume adjustment mechanism driven by a high-torque geared electric motor
• Durable, low-friction gear train supported by precision sealed ball-bearing
• Supplied with all parts and wiring required to have it up and running quickly and easily

Install Guide

Using GFB’s TMS technology the Mach 2 can help return the engine to peak boost up to 30% faster than a factory diverter valve when shifting gears (more information below).

• Recirculation model for direct factory replacement for performance without the noise
• Atmosphere venting kits to convert the recirculating valve if you want noise with your performance

Like the Respons and Deceptor Pro II, the Mach 2 is available in a range of bolt-on kits for most popular turbo models. And when we say “bolt-on”, that’s exactly what we mean! No additional adaptors, parts or vehicle modifications are required – simply remove the factory bypass valve and replace it with the Mach 2 – it’s that simple!

The Mach 2 is configured as a 100% recirculating valve (i.e. bypass, plumb back) and add on kits are also available to convert to 100% atmosphere venting.

Use the recirc model for direct factory replacement when you want the performance WITHOUT the noise! Add the conversion kit when you want some noise with your performance!

Factory bypass valves have two main shortcomings – one is that they are typically designed to start opening above a certain pressure to protect the engine, and the other is they are not optimised for throttle response. Oh, and you can’t vent them to atmosphere without stalling your engine…
The Mach 2 solves all of these issues. It can effectively hold unlimited boost (unlimited in that no turbo could ever produce enough pressure to damage it), and the TMS technology ensures maximum throttle response

ACL Race Series Oil Pump

From the makers of ACL Engine Bearings comes a new line of high performance oil pumps Subaru applications.

Tuning Notes:

Because this upgraded solenoid affects the way that your vehicle controls boost, it is always recommended that you consult with a tuner immediately following installation. It is not recommended that you drive the car in a way that builds boost without doing so. If you have any questions, don't hesitate to get in touch with us directly!

Suits:

• 01-07 WRX & STI

The Stage 1 clutch kit uses an upgraded pressure plate with increased clamping pressure, combined with an organic friction disc. Stage 1 delivers substantial increases in performance and power holding capability whilst retaining near factory type driveability, and is designed primarily for high performance road going vehicles.

These kits feature a high quality cover with increased clamping force compared with standard, between 20-40% depending on the demands of the individual vehicle.

They use an organic friction disc to retain drive-ability similar to standard.
