Stage 4 Breakdown

The Supercar Slaughterhouse

"Sheeesh! The car doesn't even sound like a BMW anymore. When you hit the trans-brake, the entire chassis shakes. You let go of the button and teleport to the next intersection."

Target Output 1350 - 1500 HP
Estimated Cost $53,500

Engine Architecture

Fully CNC machined engine block, Darton Sleeved, and Fire-Ringed (copper wire rings machined into the block to bite into the head gasket, preventing head lift at 40+ PSI). Upgraded Schrick camshafts and a ported cylinder head for maximum volumetric efficiency.

Turbo & Aspiration

Precision PTE 7275 Next Gen. This turbo is physically massive. It requires a custom tubular exhaust manifold, twin TiAL 44mm wastegates, and a massive 5-inch fender-exit exhaust. Spool doesn't happen until 4500 RPM, but when it hits, it produces violent acceleration.

Transmission & Drivetrain

Pure Drivetrain Solutions Stage 3 or Kotte Performance Stage 4. Includes a custom Billet Stator Torque Converter designed specifically to allow the massive 7275 turbo to spool on the trans-brake before launching.

Fueling & Engine Management

Motec M142 Standalone ECU managing everything. Full closed-loop fueling with individual cylinder knock control. Mechanical fuel pump conversion (belt-driven Waterman pump) flowing pure Methanol or E98.
