This is muscle car energy that is built with one thing in mind: power. The Pentastar V6 has served as a solid workhorse engine for Chrysler vehicles since its introduction in Sandwiched between the economical four-cylinder and the beastly HEMI V8, the Pentastar V6 is known as a reliable, do-it-all engine that can kick out the power without sacrificing fuel efficiency.
Most people who truck, tow. The Pentastar V6 is rated for up to 3 tonnes or more of towing capacity. For most people and most jobs that will be more than enough. Need to haul a trailer, boat, or heavy load? The answer is that the V6 is likely up to the task. The V8 option with eTorque does, even more, to kick up the savings for a heavy-duty engine by replacing the traditional alternator with a volt battery-powered, belt-drive motor generator that gives the fuel consumption a rest and lets efficiency take center-stage as well as lending a helping hand to towing and payload capabilities.
Hemi just a engine that has hemispherical heads on it to get more cubic inches out of it the srt means street racing technology by dodge its a team of performance guys who make stock cars from dodge better and more race ready.
Chase answered 12 years ago. Kevin answered 12 years ago. A hemi typically has a hemispherical style combustion chamber instead of the typical canted valve style head. What is the feature differences between the highlander base, Se and limited models?
A coworker is saying that a blowoff and recirculation valve are the same thing. We have already been online looking it up can someone tell me the difference between the two parts.

Recall from high school biology that surface area, such as your skin, is one of the ways heat dissipates. In an engine, if the head shape and size is larger than the size of the combustion chamber, the large surface area of the head loses more heat than the chamber generates.
Loss of heat amounts to a loss of energy. Fuel must burn, or undergo combustion, to release usable energy. When the large surface area of the head loses heat, fuel never gets hot enough to burn and release energy.
The HEMI hemispherical head surface area is quite small compared to a traditional flat-head engine. HEMI loses less heat, allowing for higher pressure, higher heat, and more fuel combustion. The HEMI design places angled valves on either side. In the HEMI design, spark plugs are positioned on top of the combustion chamber. Previous designs placed valves in a single-file line, which limited each valve's potential size.
With valves on either side, there is more room for valves to be larger. HEMI valves are much larger than inline valves. Thanks to this larger size, HEMI valves excel at the conduction of airflow through the engine.
The concept for the HEMI engine dates back to Most cars had just four cylinders with domed cylinder HEMI heads, albeit a basic design. Flash forward to and the post-world war development of the six-cylinder engine, thanks to Harry Westlake and his team.
The engine, developed for Jaguar, was the first of its kind to actually employ the basic technology for the HEMI that would spawn decades of innovation to come. Chrysler continued on its path of HEMI domination, producing engines with a displacement of by and in , cubic inches. Its elephant engine, a horsepower street HEMI was offered just a year later.
Interestingly, HEMI had its share of detractors in the racing world because vehicles equipped with the engine came out on top in record numbers. Vehicles with HEMI engines won 26 of 62 races in the stock car truck series.
