Frequently Asked Questions
SKU: FSX-205
Improved Racing's Flow Series Extreme (FSX) oil thermostat is a universal solution that can be used with any oil cooler on any vehicle or industrial application with very high fluid flow rates of up to 33 GPM (125 LPM) for engine oil and 50 GPM (189 LPM) for low-viscosity fluids such as water.
The FSX was specifically designed for use in diesel engine applications, including semi trucks and large pickup trucks, which require higher oil flow rates than passenger vehicles. It can be used with -12AN, -16AN, or even -20AN fluid lines.
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 -16AN O-ring boss threads and is available with optional AN fittings in -12AN and -16AN. The included brackets allow for multiple mounting options.
Operation
Features and Benefits
- Designed for specifically for large diesel engine and transmission applications flowing up to 33 GPM (125 LPM) of oil and up to 50 GPM (189 LPM) of water
- 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
- Rebuildable
- 6061-T6 billet aluminum construction with black MIL-A-8625 Type II anodized finish
- Lightweight at just 18.1 oz (514 g) without brackets or fittings
