Where the Ti-VCT Coyote V-8 shines is its completely new cylinder head design and function; it has maximum flow into each cylinder and greatly reduced valvetrain friction and weight. Larger cylinder head bolts and improved sealing technology help contain much higher 11.0:1 compression.
Because the Coyote development timeline was tight, the team had to fast track this engine through development, prototyping, testing, certification, and into production. The traditional three-year development window to get this thing turning and burning was not an option. Existing Modular mule engines had to be used to work and test Coyote engine parts for durability. A lot of scrap that didn’t measure up went into the recycle bin.
Engine Specifications
The Coyote engine has been produced in three basic versions between 2011 and 2016. From 2011 to 2014, induction is conventional. From 2015 and on, the Coyote is fitted with Charge Motion induction and cylinder heads. The Shelby 5.2L Voodoo is a standalone Coyote-based engine.

To get the Ti-VCT where Team Coyote wanted it necessitated a lot of back and forth between hardware people in engine building and dyno rooms and software geeks who compared
