Knowing your coolant temperature can help to prevent burn injuries. Thermo Cap, with its built-in calibrated thermometer, indicates the coolant temperature. This is useful information prior to cap removal. Never attempt to remove Thermo Cap when the coolant temperature is very hot. The escaping hot coolant and steam may burn you. Check the Thermo Cap temperature indicator to determine if the coolant is cool enough to make removing Thermo Cap safe. If the coolant is very hot, then thoroughly rinse the radiator with cool water, until the coolant temperature drops into a cooler safe zone Thermo Cap’s integrated coolant reclamation valve works great with your coolant recovery system. Your radiator can reclaim coolant from your overflow bottle. Wide 30 degree to 270 degree Fahrenheit temperature range. Calibrated in centigrade and Fahrenheit. Color-coded temperature ranges. Chromed crown with a colored trim ring. Indicates coolant temperature, Helps to prevent coolant injuries, integrated coolant reclamation valve, Improves under hood appearance, Fits most domestic or import vehicles and various valve pressures available.

Hypertech is a technology-driven company with a unique status in the aftermarket industry. Unlike other speed equipment manufacturers that produce hard parts like camshafts and cylinder heads, our core product is knowledge the ability to tune the complex computers that control essential functions in modern automobiles. We have invested in people, not machinery. The knowledge and skill of the Hypertech team are our most valuable assets. Our staff of engineers and technicians has degrees in a variety of disciplines, including electrical engineering, computer science, and mechanical engineering. Hypertech people know computers from the inside out! The Hypertech team is passionate about performance. We have racers, hot rodders, and performance enthusiasts on our staff. You’ll find modified trucks and street machines in our employee parking lot. We build project cars and use our trucks for towing on weekends. We come from different backgrounds, but we have all learned to appreciate the tremendous power of electronic engine controls to improve performance on the street as well as on the race track. Hypertech is the technology leader in High-performance engine tuning computer-controlled vehicles. Electronic engine controls have evolved rapidly since their introduction in the early ’80s. Hypertech has kept pace with these rapid advances in technology by developing power tuning products that take advantage of the capabilities of these electronic controls. Early automotive computers used replaceable PROMs or chips to calibrate the Electronic Control Module (ECM) for a specific engine, powertrain, and vehicle combination. Hypertech created the original Power Chips to recalibrate these electronic brains for improved performance. As the power of digital systems expands, Hypertech will continue to design and manufacture power tuning products that are on the cutting edge of technology.

HoleShot 3600 for GM 1965 to 1991 TH400, 425, 375 and 1968 to 1981 TH350, 375B (not 350C) APPLICATION: HoleShot 3600 for GM 1965 to 1991 TH400, 425, 375 and 1968 to 1981 TH350, 375B (not 350C) A higher than stock stall speed as delivered by the Holeshot converter will provide several advantages and benefits in vehicles with modified engines. Many modifications, particularly big cams, tend to reduce low end power and torque. The high stall converter allows the engine to launch the car at higher rpm where more torque is available. The Holeshot is generally a very good choice for the typical street machine that is looking for better launch capability and more strength. Street rods with modified engines will also benefit from a Holeshot converter. If your vehicle is equipped with a plate type nitrous system, you will need a Nitrous Holeshot!! Stall speed listings are based on engines producing 230lb. ft. of torque at 2,500 rpm. More torque at 2,500 rpm will give you more stall speed, less torque at 2,500 rpm will give you less stall speed than the stall speed ratings indicated. Furnace brazed impeller. New precision steel alloy pump drive tube. New heavy duty needle bearing between stator and impeller (not a thrust washer). Needle bearing between stator and turbine. Furnace brazed turbine.
