Power Driven Aggressor 98mm Turbocharger — Large Compound First-Stage Turbo

The GTX5533R has long been the benchmark for high-horsepower compound turbo builds — but the price tag keeps most builds from running one. The Aggressor 98 brings the same dual ball bearing, billet compressor, and stainless T6 turbine housing platform to a price point that makes 1,200–1,800 HP compound builds actually viable. Designed specifically as the atmospheric first-stage turbo in a compound setup, the 98mm x 133mm x 138mm ETT billet compressor wheel and 1.0 A/R open volute T6 housing are optimized for maximum airflow at the top end — up to 230 lbs/min — with EGT reductions up to 500°F in 1,000+ HP towing applications.
