Project Name: Project Ice Box
Car: '01 Mustang GT
Timeline: February 2002-Present
Goal: Push the boundaries of 4.6 Two-Valve street performance.
Grade: A
Best performance: 10.73 at 131 mph on ET Streets/10.9 at 133 in daily driver trim (radials all around, 3650 lbs). Emissions legal in 49 states (Vortech T-Trim not emissions legal in California), A/C still blows cold.
Biggest mistake: Coilover suspension not up to 621 rwhp on road course.
Best move: Patriot heads, Comp Stage 2 cams, CHP short-block, JDM tune-up.

Seems like there's no limit to 4.6 performance.
