Gains are 6 to 8 horsepower on a 5.7L engine, 8 to 10 horsepower on a 6.1L, and even more on stroker and head & cam motors. Actual Quarter-Mile Track testing has shown a full 1/10th improvement in the quarter mile and 1 mph increase in trap speeds! For those looking to get the most out of their HEMI that is huge!!! Unlike other throttle bodies, the Modern Muscle is an easy bolt on, fully plug-n-play and is undetectable unless you remove the air intake. It also has absolutely no drive ability issues unlike other throttle bodies on the market.
Jet Performance 180 Degree Thermostat - 5.7L & 6.1L HEMI Engines
Reduced engine temperatures add life to your engine and provide a denser air/fuel mixture which helps produce more horsepower. Consistent control of engine temperature allows an engine to operate at its peak efficiency no matter what the driving conditions. The factory 205 degree thermostat simply cycles open and closed, this reduces cooling efficiency in any engine. With the JET 180 degree thermostat you get consistent engine cooling and a precise metering of water throughout the engine. Constructed of stainless steel the JET Thermostat offers a lifetime warranty.
