Things get started with a Powerflo lift pump in the factory tank, with one of Fleece’s auxiliary fuel filter and line kits mounted between the lift pump and a single Powerflo 750 CP3. To take advantage of their quick injection rate and also to provide room for future horsepower growth, a set of 5.9Lderived, 100-percent over injectors were obtained from S&S. Fine-tuning of the engine is made possible through the use of a 5.9L ECM.
SECOND-GEN TURBO SWAP
With the finished product destined to live in Kenneth’s native Wyoming, adequate airflow without sacrificing drivability was a key stipulation in the build. Sizing a turbocharger for a single turbo application that needs to be responsive at 7,500-feet of elevation but that can also support more than 700-rwhp can be a tall order. However, Fleece met Kenneth’s needs with an S463 that makes use of an 83mm turbine wheel and a non-wastegated .90 A/R exhaust housing. Accommodating the Borgwarner charger is Fleece’s popular second-gen turbo swap system, which (in addition to facilitating the use of an S400 on a 6.7L common-rail) includes a T4 Steed Speed exhaust manifold, 4-inch stainless downpipe, and the company’s
