HushMat Complete Vehicle Insulation Kits

HushMats complete vehicle insulation kits serve two important functions: reducing thermal transfer into your interior, and reducing the noise level by up to 15 decibels. Your engine, headers, manifold and exhaust generate tremendous heat that transfers to the metal firewall and floor—forcing your A/C system to work harder to maintain a comfortable environment. HushMat auto heat shield is proven to lower this temperature by over 40 percent. At the same time, when you drive on the highway at 65 mph, most vehicles approach 80 to 90 decibels of noise. That's like a vacuum cleaner or garbage disposal running on your passenger seat. These insulation kits use a specially designed sound deadening material to deliver a more peaceful ride. Each kit is packaged specifically for your vehicle to provide 100 percent insulation coverage—no holes in the material and no puzzle pieces to assemble. Treat your firewall, doors, floor, tunnel, rear wheel wells, trunk floor, and roof with these HushMat barriers. Order the complete insulation kit designed for your specific vehicle. Additional details: * Reduces road noise and vibration, low-frequency noise from 0 to 1,000 Hz * Stay warmer in the winter and cooler in the summer; withstands ambient temps from -30 up to +550 degrees F * Lightweight and super flexible mats; less than 1/8 in. thick and 0.47 lbs. per sq. ft. * Adhesion is guaranteed; no alcohol or acetone wash needed; no tools required * Trims easily with standard razor knife or household scissors * Self-adhesive peel-and-stick; no glue required * Outperforms closest competitive brand by over 40 percent * OEM approved; meets or exceeds auto damping specs GMO 149M – General Motors; WSB-M5G58-A1 – Ford; and MS-CD 629 Type C – Chrysler

APR DTR6054 Turbocharger Systems

APR DTR6054 turbocharger systems are direct replacements for the EA888 Gen 3 engine. These upgrades include matching software for various vehicles and mods, providing up to 491 hp and 425 lbs.-ft. of torque, depending on vehicle platform and fueling, all while keeping emissions components unmodified. The software supports premium pump fuel grades, race fuel grades, and even ethanol on the Golf R, S3, and TT S platform with fueling upgrades. For dedicated race cars the turbocharger is designed with plenty of headroom to go even further on your own! Designed and developed from the ground up by APR, DTR6054 turbochargers do not require a core and there's no additional downtime. They are built using an aluminum anti-surge compressor cover with appropriate A/R matched to a larger aircraft-grade, 6061 billet aluminum 60mm compressor wheel, a turbine housing cast with high-temperature 310 stainless steel to take the heat and abuse seen on a road course, and a nickel-based superalloy K418 high-flow 54mm turbine wheel. A German dual ceramic ball bearing center section provides smooth and reliable operation with a better transient response, eliminating the factory failure-prone journal bearing design. Each kit includes the complete turbocharger with compressor inlet pipe, compressor outlet hose, T-bolt clamps, gaskets, O-rings, exhaust ring, exhaust V-band, exhaust manifold gasket, studs, bolts, and washers, oil and coolant line O-rings, and APR's ECU upgrades for select vehicles. The upgrade uses your factory electronic wastegate and diverter valve, and connects to your factory exhaust, intake, turbo outlet pipe, and oil and coolant lines. Tested at various road courses, APR's DTR6054 turbocharger systems do not spike torque hard or run on the edge of what the factory rods and pistons have been known to handle, making them as safe on the stock engine as possible for these power levels. Additional features: * Over 30 percent compressor flow compared to the factory turbocharger * Various software levels depending on fueling modifications, including stock fueling * Supports 91, 93, 100, and 104 AKI in all configurations * Supports E60-E85 with fueling upgrades (Golf R/S3/TT S platform only) * VSR balanced turbocharger center housing rotating assembly (CHRA) for reliable operation * Oversized cast turbo inlet pipe connects directly to factory or upgraded intake system * Machined turbocharger speed sensor port with included billet block-off plug * Silicone discharge hose with APR EZ-flow stepped lips included (no turbo muffler) * Integrated diverter valve (DV) port * Available in turbo kit only, turbo kit with low- and high-pressure fuel pump, or turbo kit with low- and high-pressure fuel pump and multi-port injection

They feature .220 in. raised intake runners and .100 in. raised exhaust ports that provide a better line of sight into the cylinders and allow for an improved short turn. The raised intake runner design fits both stock and aftermarket LS7 intake manifolds and can be used with stock or aftermarket valvetrains. The heads utilize the GM LS 6-bolt design, making them compatible with the GM LSX block and all aftermarket iron or aluminum 6-bolt per cylinder LS race blocks. The design offers increased clamping capacity over the standard factory 4-bolt configuration and improves head gasket sealing, making them ideal for high-compression, naturally aspirated engines and high-boost applications. Edelbrock Victor CNC cylinder heads feature a 12-degree valve angle and fully CNC-machined ports for maximum airflow. CNC-machined runners and chambers, as well as the .220 in. raised intake ports and the valve angle, increase overall flow capability, while a revised water jacket design enhances thermal conductivity and tunability. The manganese bronze valve guides withstand long wear with emphasis placed on holding precision tolerances on valve seat concentricity, allowing the valves to seal securely, eliminating leak down and increasing cylinder pressure during engine operation. Finally, the .700 in. thick deck and .400 in. raised valve cover rail make these heads ideal for maximum horsepower and high valve lift applications. All Edelbrock Victor CNC heads feature patented Clean Cast Technology, a process that eliminates casting flaws and promotes a smoother internal surface finish for greater air and coolant flow. These benefits provide more power and increased cooling ability.
