For Ford Inline-6 Turbo & Supercharged Builds

When you’re ready to turn up the wick, the PMAX BOOSTED BIG SPOOLER delivers the airflow and timing to feed your hungry boosted Ford six. Designed for engines that live under boost and love to pull hard into the upper midrange, this cam bridges the gap between street performance and serious track duty.

RPM Range:
2200–5500 rpm—perfect for builds that need stronger top-end charge without giving up street manners.

Boost Compatibility:

• Up to 12 psi on 93 octane with 10% ethanol

• Over 12 psi requires E85 or race fuel

Camshaft Specs:

• Lift: .578”/.578” (using 1.73 ratio rockers)

• Advertised Duration: 280°/278°

• Duration @ .050” Lift: 228°/226°

• LSA: 112°, no advance

This profile is built to spool larger turbos quickly and hold boost solid through the mid to upper revs, making it ideal for street bruisers and track terrors alike.

Tech Tip: Always confirm coil bind clearance and piston-to-valve clearance when stepping up to this aggressive profile, and pair with appropriate valve springs.
