 IHI VF48L/Stage 2 Turbo Single Scroll

With an upgraded compressor wheel and reinforced bearings, capable for an added extra 20-30kw over the stock VF48.

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

Suits:

• 97-98 Impreza WRX

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

Deceptor Pro II features
Direct bolt-on for most vehicles available:

• 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

Suits:

• 98-00 GT Forester
• 03-04 XT Forester

Genuine Subaru VF48 Turbo Single Scroll 

 

Featuring GFB’s patented venting bias adjustment system, the Respons allows you to precisely control how much air vents from each of the two outlets.

Why is this so important? Two key reasons:

Adjust how loud the blow-off sound is. Recirculate all of the air for silent factory operation, vent it all to atmosphere for maximum noise, or set it ANYWHERE in between to suit your preference.

Get a blow-off sound WITHOUT causing stalling, backfiring, or any other BOV-related issues, even on a car with a sensitive airflow meter (MAF).
Hold on, it gets better. The Respons isn’t just a noise-maker. It also;

• Offers better throttle response
• Faster boost recovery on gearshift
• Unlimited boost-holding!

For example, using GFB’s TMS (Turbo Management System) principle, tests show that the Respons can return the engine to peak boost up to 30% faster than a factory diverter valve when shifting gears.
