Performance - Audi S1 8X

TECHNICAL DATA AIRTEC have released their Audi Sport S1 Front Mount Intercooler upgrade to its growing range of performance intercoolers. Audi have made a great job of shoehorning the 2.0 TSI from the Golf GTI into the small chassis of the S1 Unfortunately, due to the size restrictions of the S1, they have made a huge compromise in the intercooler department and the S1 intercooler is a third of the size found in the Golf GTI. Road tests found the standard intercooler was heat soaking (unable to cool the intake temps from turbo) and temperatures rising to 69 degrees which causes the ecu to pull timing out of the map and means a drop in bhp. With the AIRTEC intercooler upgrade fitted, the intake temps didn’t rise above 24 degree’s which means no loss in bhp. Test taken on standard S1 using Snap-on Ethos. We take a huge amount of pride in making sure our kits are finished to an extremely high standard. Why not make your S1 stand out by choosing Super Stealth satin black for a more OEM look or go for the Silver finish for the maximum impact. Great addition to your standard or re-mapped S1. AIRTEC Front mount Intercooler Features 1 x Huge stepped Intercooler core 80mm bottom section and 60mm top section, with flowed cast end tanks, this means less welding and a stronger Intercooler Un-Beatable value for money Proven Power Increase’s for Fast Road & Track Airtec 3 year unlimited mileage warranty Fitting will take 3-4 hours depending on mechanical skill Fits to standard hoses Finished in Pro-Series Satin Black or Natural Silver, please choose from options Optional Airtec logo Approximate sizes 875mm width 200mm height 80mm/60mm thick Airtec Part No: ATINTVAG15

Revo ProPanel FilterHigh-Performance Air Filters OVERVIEW The Revo ProPanel is a high-grade direct replacement filter for your vehicle. Designed as direct replacement filters to fit inside your factory airbox and are suitable for road or competition use.   BENEFITS Designed to increase horsepower and rate of acceleration Exceptional filtration High air flow with three layers of foam Lifetime warranty Cleanable (Every 10,000Miles or 12 Months) Works with original manufacturers airbox   DESIGN AND PERFORMANCE Why choose foam? Because, compared to paper or other filter technologies, reticulated polyester foam achieves optimum performance against three key criteria: Maximum airflow: the ability to allow air to pass through without causing a large pressure drop. Cleaning efficiency: the capability to arrest a high proportion of airborne dust while feeding the engine clean air. Dust load-up tolerance: the capability to absorb a large amount of dust without reducing air flow capacity. This design of filter has been used in all fields of motorsport from Formula 1 to the World Rally Championship. The range receives this same attention to detail at the design stage and is then taken into production with consummate quality.   THREE LAYER FOAM SYSTEM Revo ProPanel Filters use multi-layered foam technology to trap dust and dirt while maintaining flow efficiency over time. Using foam increases the filter's surface area and is washable, compared to standard paper and cotton filters which trap dust on the surface and become less efficient the more they are used, choking the engine and reducing performance. The outer core is a coarse foam designed to trap larger particles, the second layer is a medium foam designed to trap most particles and the inner core is fine foam which will trap any particles small enough to reach it. The triple layer foam design ensures an exceptional level of engine protection and long-term performance advantage.     1: Stainless steel wire mesh To avoid erosion, only the highest quality steel is used.   2: Course outer layer:  Stops large pieces of dirt and foreign matter from penetrating further. Straightens airflow into subsequent layers.   3: Medium grade middle layer:  This second filtration layer traps most of the harmful dirt that leads to engine damage.   4: Fine inner layer:  Extracts fine particles while allowing full airflow to the engine for maximum power.     ADVANTAGES OF A REVO PROPANEL FILTER Emissions legal in all 50 US states Will not void vehicle warranty Lifetime warranty (to the original purchaser with proof of purchase)     FITMENT      Manufacturer Model Engine Year Audi S1  2.0 TFSI  2014 > VW Polo GTi  1.8 TSI  2015 > Seat Ibiza Cupra  1.8 TSI  2015 >     Notes: Simple replacement of the OEM part Please contact your local Revo Authorised Dealer for additional information and availability.

The VTA is a performance blow-off valve solution for Audi, VW, Skoda and SEAT vehicles with an electronic factory diverter valve. If you want sound with your performance (or performance with your sound!), GFB’s VTA delivers just that! By combining the proven performance benefits of our ground-breaking DV+ with atmosphere venting, the VTA delivers an aggressive blow-off sound, improved throttle response and boost recovery, as well as superior boost holding and reliability in extreme conditions. The VTA shares the successful DV+ design philosophy: “Keep what works, replace what doesn’t” This means we retain ECU control and the solenoid from the factory diverter to ensure the fastest possible response time, without the added and unnecessary cost of replacing the solenoid like some brands do. The weak part of the factory diverter has always been the plastic valve mechanism – this is the part we replace. The VTA features CNC machined billet components that last a lifetime, and we also change the valve operation method for better performance. The factory diverter valve can only operate in two states – open, or closed. When it opens fully at low boost, or during a partial throttle lift mid-corner, it causes increased lag and a noticeably non-linear boost transition. GFB pioneered the use of “pilot operation” in the DV+, which works by repurposing the factory solenoid to control the pressure behind the piston rather than the piston itself. This allows the solenoid stroke to be much shorter, speeding up the response time and increasing the actuation force. More importantly, it allows the piston to open and close progressively in response to the amount of boost pressure present, which smooths boost transitions and reduces the lag caused by the factory diverter valve. It is this design philosophy that makes the VTA not only the best performing blow off valve solution, but also the best value on the market.   VTA or DV+?Depends if you want sound or not. Both valves are constructed with the same quality materials and valve mechanism, and both offer the same performance and reliability benefits. However, the VTA vents to atmosphere for sound whilst the DV+ recirculates the air to keep it quiet. Why choose a VTA over a “BOV spacer”?“BOV spacers” are cheap and they make sound. But that’s it. All the inherent performance and reliability issues you get with the factory diverter valve remain, because a spacer doesn’t change the diverter valve in any way. The VTA improves the operation of the diverter valve for sound AND performance. Why choose a VTA over a kit that includes a solenoid?Because there’s no performance benefit to replacing the factory solenoid, only a much higher price! If a VTA with the factory solenoid can open in a couple of hundredths of a second, why pay more than you need to?       VTA BLOW-OFF VALVES ARE CONSTRUCTED WITH THE SAME MATERIALS AND VALVE MECHANISM AS THE DV+, AND THEY OFFER THE EXACT SAME PERFORMANCE AND BOOST HOLDING. HOWEVER, VENTING TO ATMOSPHERE GIVES IT THE SIGNATURE BLOW-OFF SOUND, WHILST THE DV+ KEEPS THINGS QUIET. COMPETITORS' PRODUCTS FOR THE SAME VEHICLES THAT MAKE SOUND (I.E. BOV "SPACERS") TYPICALLY RETAIN THE PERFORMANCE DEFICIENCIES OF THE FACTORY DIVERTER VALVE, DELETE THE ECU CONTROL, OR REQUIRE FREQUENT MAINTENANCE AND REBUILDS. THE VTA ON THE OTHER HAND IS THE COMPLETE PACKAGE - PERFORMANCE, FIT, RELIABILITY, AND SOUND! Like the DV+, GFB’s VTA range of BOVs utilise GFB’s proven TMS Technology to ensure rapid boost recovery on gearshift and optimum throttle response, as well as superior boost holding. However, where the DV+ and the VTA range differ is what they do with the vented air. VTA BOVs vent to atmosphere to make the signature turbo blow-off sound, where the DV+ recirculates the air to keep it quiet. Each valve in the VTA range is designed specifically for the applications we list them for, ensuring the best fit and performance. Most of the VTA range are designed for use on cars with solenoid type factory diverter valves, and in those cases the VTA kit will retain the solenoid and ECU control. Like the DV+ though, it replaces the weak factory valve internals to ensure strength and reliability, especially in high boost applications. Other versions of the VTA are designed for use on cars that do not have any kind of factory fitted diverter valve. Vehicle manufacturers have deleted the troublesome solenoid type diverter valve from some of the newer models, but this leads to turbo compressor surge which can be taxing on the turbo in the long run. The VTA valves for these cars are designed to re-introduce the function of a diverter/blow-off valve to help protect the turbo in the long term and provide a blow-off sound.
