Improved Racing high-flow flapper check valves are ideal for use in oiling systems (wet sump and dry sump), fuel systems, crankcase pressure ventilation systems, and more. Most check valve designs—including poppet check valves, ball check valves, diaphragm check valves, piston check valves, and others—are restrictive, resulting in a pressure drop across the valve even when fully open. Improved Racing's check valves use a flapper design, originally developed for military jet engine turbines, that swings completely out of the fluid's flow path, adding virtually no flow restriction. These check valves were further optimized for low restriction at high flow rates using flow simulation software—and were designed to exceed most military specification requirements. The valves have been tested at up to 1,000 psi of backflow holding pressure without catastrophic failures or excessive leakage. This allows Improved Racing to very safely rate these valves to hold 300 psi of backflow pressure under normal operating conditions with a very high factor of safety. For comparison, the military surplus flapper check valves tested failed catastrophically with complete pressure loss at less than 200 psi. This flapper-style valve has a very low cracking pressure of less than 0.05 psi. Every internal component (hinge, spring, hinge pin, and gasket core) is made from stainless steel to ensure long-lasting, reliable performance and compatibility with just about any fluid, including corrosive fluids. The check valve's gasket is made from FKM (Viton®) rubber bonded to a stainless steel core, giving it a high operating temperature of up to 302 degrees F. It's also highly chemical-resistant and compatible with all types of fuel. Improved Racing's check valves are available in multiple fitting sizes, and the inlet and outlet halves can be mixed and matched to create a completely custom valve. Features and specifications: * Flapper design allows for very high flow with low restriction * Design optimized using flow simulation software * FKM (Viton®) rubber seal * All stainless steel internal components for compatibility with a wide range of fluids * 6061-T6 billet aluminum body with black MIL-A-8625 Type II anodized finish * Laser marked with flow direction and hinge location per military specification * Maximum operating backflow holding pressure of 300 psi, burst backflow holding pressure of over 1,000 psi * Maximum unchecked (normal direction of flow) operating pressure of over 1,000 psi * -40 to 302 degrees F operating temperature rang * Lifetime Warranty

Proper oil pan baffling is critical for improving oil control and reducing oil starvation in high performance engines. Improved Racing oil pan baffles provide effective, track-proven protection against oil starvation for road racing, drifting, autocross, drag racing, and even off-roading and rock crawling. The baffles use trap doors to keep oil around the pickup tube and provide vastly improved oil control over the stock baffles. They are sufficient to prevent oil pressure drops at up to 1.4 sustained lateral Gs in most vehicles. Even semi-dry sump systems suffer from oil aeration when the pickup tube in the oil pan sucks up air, aerates the oil, and fills the dry sump tank with foamy oil. Foamy oil is compressible and results in oil pressure drops when pumped into the engine. Improved Racing baffles help keep more oil around the pickup tube in the oil pan, reducing oil aeration and improving oil pressure. Features and benefits include: * Directional trap door baffling completely encloses the oil pump pickup for maximum protection against oil starvation at high Gs * 100 percent bolt-in, no welding necessary; most are direct replacements for stock steel baffles * Baffle plates with drainback slots help to accelerate the return of oil to the bottom of the sump, while also preventing oil slosh and reducing oil consumption * Reduce the risk of oil starvation when oil levels are low * Work with OE cast aluminum oil pans, often a structural member of the engine block, and are less prone to failure or leaking than sheet metal oil pans * Lightweight aluminum construction * Solid body aircraft rivets used to secure trap doors * Limited lifetime warranty

Improved Racing created the first bolt-on automatic transmission fluid adapter with a thermostat for GM's 6L, 8L, and 10L automatic transmissions. Each adapter's built-in thermostat automatically bypasses the transmission cooler until the fluid reaches operating temperature. The thermostat reduces rough shifts caused by overcooled transmission fluid, reduces wear, and improves efficiency and horsepower. Your transmission can now reach operating temps quickly while retaining the cooling capacity needed for high load activities such as towing or racing. It's the best of both worlds! Adapter model TGM-100-T2 features SAE female -6 AN O-ring boss ports that accept adapter fittings for 5/16, 3/8, 1/2 in. hose barbs or male AN fittings. This allows you to run common rubber transmission cooler lines or braided AN lines. Hard tube adapters may also be used to connect the factory lines directly to the adapter (may require minor bending or adjustment of factory lines). Important application notes: * The adapter can only be used in conjunction with external transmission fluid coolers. * The adapter does not directly connect to the factory hard lines. Aftermarket lines or hard tube adapter fittings must be used. * The adapter will only help resolve rough shifting issues if they are caused by overcooling of the transmission, usually due to the addition of a larger aftermarket transmission cooler. Note that 8L45 and 8L90 transmissions rough shifting issues can often be resolved through GM TSB 18-NA-355 and by simply flushing the transmission fluid. Features and benefits: * Bolt-on fitment for 6L, 8L, and 10L series General Motors automatic transmissions (adapters are required for connecting to factory lines). * Built-in thermostat prevents temperatures from dropping below optimal levels, reducing wear, improving efficiency and horsepower, and helping to eliminate rough shifting. * SAE -6 AN female O-ring boss ports for connection flexibility; choose any line size and type you want. * 6061-T6 billet aluminum construction with black MIL-A-8625 Type II anodized finish. * Uses the factory GM transmission cooler adapter gasket. * Lifetime Warranty Includes: * TGM-100 transmission cooler adapter block with built-in thermostat * Transmission cooler adapter gasket * Zinc-plated steel mounting screws * Installation instructions Applications: * Fits most General Motors 6L, 8L, and 10L series automatic transmissions, including: all 45, 50, 60, 70, 80, 90 variants, and aftermarket performance versions * Fits both E and non-E transmission variants
