Project RSC: Naturally Aspirated vs. Zex 100hp NitrousFinally, Project RSC was going to have some street credibility. Though powerful for an early 4.6 at 274 rwhp, it had to resort to the juice to make major-league power. All it took was a simple, 100hp shot from a Zex wet fogger system, and our 274 rwhp jumped to 377, while the peak torque skyrocketed from 316 lb- ft to 497. Yes, we missed the 500 lb-ft mark by just 3. Note the billiard-table-smooth power curve, reaching 375 hp at 4,300 rpm and never dropping below that point (or exceeding 377 hp) for nearly 2,000 rpm.
