The 3.6 Pentastar is one of the most advanced V6 engines, and as a result, has earned the trust of popular car brands out there. This Pentastar engine was on the top 10 engines in the US market for three consecutive years.
This powerhouse is rated at 305 horsepower, 270lb-ft of torque. However, there’s more to the engine than these numbers can tell. It features brilliant engineering and impeccable crankshaft that fosters unrivaled output and, most importantly, longevity in service. The engine is smaller, more fuel-saving, lighter, and more potent than its 3.5L predecessor. Moreover, it has a die-cast aluminum high-pressure cylinder block that has a 60-degree V-angle between cylinder banks. In addition, the cylinders have cast-iron liners that are meant to make them last longer.
The 3.6 Pentastar is a powerful engine and can handle a pretty massive boost compared to its competitors. It can safely handle 10-12 pounds of boost. Also, approximately 90% of max torque is achieved within the 1800-6350 rpm range. Above all, you get smooth operation and high efficiency at any rpm.
The 3.6L Pentastar utilizes a timing chain in place of a timing belt. The timing drive uses four chains, each of which is a “silent chain link” design to improve engagement with the sprocket thus reducing noise, vibration, and harshness.
This 3.6L Pentastars are still excellent engines and would make a quality engine choice even in the few years to come.
