In Part 1 of this step-by-step tutorial, you learned how to get started installing a 85mm unit onto an ’08 Challenger with a 5.7L Hemi engine. This next section will cover a bit more of the team over at BBK Performance Parts and give you the final steps to a successful installation.
If you haven’t checked out Part 1, be sure to follow the link and get the first half of this step-by-step tutorial!
This engine had already been enhanced with BBK’s CNC-machined billet aluminum high-flow fuel rails and a Mopar cold air intake system, so it was in need of more airflow. The 85mm BBK unit is 5mm larger than the 80mm stocker, and that increase in airflow should translate to a 10-15-hp increase. That works out to be about a pony per minute, because this is an extremely easy install, taking only about 15 minutes to finish.
BBK has been in the performance business for over 20 years, when they started with Mustang headers. In that time, they have grown into a one-stop horsepower shop for most muscle car applications. They offer everything from fuel systems, exhaust systems, intake manifolds, pulley systems and valve covers, and of course, throttle bodies.
As for this install, follow along as this Hemi Challenger gets an increase of fresh air and its owner gets an increase in fun.
