Stage 4 Breakdown

The Transmission Terrorist

"No mames. The transmission now grabs so hard it feels like you got rear-ended by a truck on every shift. The stock block is sweating bullets."

Target Output 950 - 1000 HP
Estimated Cost $21,800

Engine Architecture

Factory Block. We are entering the danger zone. Around 1000HP, the factory cast pistons are at extreme risk of cracking if there is any detonation, and the rods are begging for mercy. Requires pristine E85 fuel.

Turbo & Aspiration

Dynamic Autowerx (DAW) Ultra Flow 6969. This is one of the largest bottom-mount turbos available for the B58, utilizing a massive 69mm compressor inducer and a 69mm turbine wheel. It flows enough CFM for 1000hp while maintaining the stock turbo location.

Transmission & Drivetrain

Pure Drivetrain Solutions (PDS) Stage 2 Built ZF8. Features upgraded clutch packs, modified pump, and upgraded baskets. It completely eliminates transmission slip and can hold 1000+ lb-ft of torque consistently during hard launches.

Fueling & Engine Management

Visconti Tuning Flex Fuel kit with a Dual Walbro 535 Low Pressure Fuel Pump (LPFP) setup in the tank, feeding a massive Port Injection rail. Direct injection is handled by the Spool Stage 3 HPFP.
