CSF Racing Radiators
CSF racing radiators feature the most advanced and efficient radiator cores in the industry. Offered for both vehicle-specific and universal applications, they use innovative tube and fin technologies with industry-leading testing methods to maximize airflow and heat dissipation. Specially engineered tubes in the shape of a "B" are carefully formed and then brazed over the seam. CSF is able to use thinner and lighter aluminum because this design is stronger than normal welded "O" shape tubes. With the inlet in the middle of a seam-brazed tube, the surface area of the tubes is increased approximately 15 percent over regular tubes. With CSF's B-tubes you get dual liquid laminar flow and the efficiency of two smaller tubes vs. one large tube in the same space. High-efficiency, multi-louvered fins are precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat rejection efficiency in CSF's wind-tunnel lab. CSF offers two all-aluminum end-tank designs to match any style and performance needs. CSF 7000 Series racing radiators have OE-style radial tanks that are flat, rounded, and welded together. Perfect for the customer who likes the sleek and smooth look, and wants to display the intricate welding. CSF deep-drawn end tanks are stamped to the same geometry of OE plastic end tanks. The only high performance manufacture to feature this advanced radiator technology; CSF deep-drawn end tanks feature less welding, and are generally considered the strongest tanks in the industry. Additional features of CSF racing radiators include: * Finished with CSF's Show-Stopper mirror polish process * CAD/CAM designed * Racing-style aluminum drain plug * Brazed in a controlled atmosphere brazing (CAB) furnace—the preferred process for aluminum * ISO 9001/9002 certification * Military-grade (special clad) aluminum used for tubes, fins, and headers * Plates and side brackets meet JIS 3003 specifications * Privately owned factories with full in-house tool rooms * CNC-machined fittings * TIG welded

Funk Motorsports Turbo Heat Shields
Funk Motorsports offers turbo heat shields for a wide range of (universal) applications, as well as vehicle-specific models for select BMW, Honda, Ford, and Subaru vehicles from 2002 and up. These turbo and/or turbo wastegate thermal blankets work to insulate the hot side and retain the heat within the exhaust gasses themselves. Hotter gasses accelerate faster, leading to them leaving the system sooner—improving spool up and throttle response. Insulating the turbo also helps to lower the amount of heat that dissipates into the engine bay and intake pipework. A cooler intake results in higher performance and more consistent power figures over time. The 4-layer shields are offered in three finishes: titanium twill, carbon fiber twill, and inside out (for turbos in contact with a heat source). Additional details: * Inside-out blankets have internal material mirrored on the outside, as well * Available for a variety of turbocharger and wastegate styles * A turbo is an absolute furnace within the engine bay. Excess heat produced by the turbo can cause devastation to surrounding sensitive components. Protect anything from oil lines, coolant lines, electronics, and even bodywork positioned close to the turbo from the dangers of excess heat * Funk shields feature specifically developed thread construction to allow for exceptional durability when removal is necessary for routine turbo maintenance. The new fireproof ultra-high temperature stainless steel thread is around 1mm in diameter and can now remain highly durable with temperatures in excess of 1,300 degrees C * New, thicker internal heat lagging insulation provides up to 3x improved heat reduction. This insulation wool is created from a ceramic silica complex matting to improve durability over prolonged heat cycles, as well as insulation quantities * ROHS tested and approved to ensure compliance and desired parameters * NOTE: Turbo blankets are not flammable. However, if any flammable fluids are introduced into close proximity of the blanket, the blanket could become a suitable ignition source for a flame to be produced. Please ensure that all necessary precautions are taken in regard to the appropriate maintenance of all oil and fuel lines and fittings surrounding the turbo charger and fuel injection system. Funk Motorsports takes no responsibility for fluid contamination their products.
