8Speed.au - 8HP High Flow Billet Transmission Oil Thermostat 165f/82c

Improved Racing's Flow Series Compact (FSC) oil thermostat is an ultra-compact unit designed for use in cooling systems for transmissions, differentials, transaxles and small engines where flow rates do not exceed 5 GPM. This thermostat is perfect for engine oil cooling in motorcycles, ATVs, go karts, and other small engines.

The patented internal design (US patent 9,772,632) minimizes the pressure drop by strategically locating the bypass valve mechanism completely out of the primary fluid flow. This design is ideal for demanding applications that require low flow restriction in a compact and lightweight design.

The device's unique, patented internal design (US patent 9,772,632) ensures a low pressure drop by placing the bypass valve mechanism completely out of the primary oil flow. This arrangement also allows for a compact design. High performance vehicles require large oil coolers to ensure that the oil does not overheat during strenuous use. These coolers also introduce the danger of over-cooling the oil and delaying engine warm-up, resulting in horsepower loss, excessive engine wear and reduced gas mileage. Oil thermostats perform the critical function of bypassing the oil cooler until the oil has reached its minimum operating temperature.

The thermostat features female -6AN O-ring boss threads and is supplied with 6an male straight to 8an male flare.

Features and Benefits

• Reduces excessive engine wear and horsepower losses while improving gas mileage by preventing oil temperatures from dropping below optimal levels
• Maintains a minimum fluid temperature according to the typical stabilization temp in the table below, +/- 2°F (+/- 1°C)
• Patented, high flow, low pressure drop design locates the valve assembly completely out of the primary fluid flow
• Allows a small percentage (less than 10%) of fluid to continually circulate through the cooler to eliminate air pockets and prevent cold fluid trapped in the cooler from shocking the system
• Thermostat can never fail in such a way that fluid flow is blocked
• Rebuildable
• 6061-T6 billet aluminium construction with black MIL-A-8625 Type II anodized finish
• Lightweight at just 7.5 ounces (212g) without brackets or fittings
