Re: Someone on XF has a 'particularly strong' C32/SRT-6 Motor. [Dyno - SI Stage I]
As posted somewhere back in this thread............
$3,400 STAGE I.
- SI Power Package Overboost Pulleys (3)
- Intake Y-Splitter Upgrade + Enlarged Piping & Clamps
- Stage I ECU Software
(torque curve shift / increased throttle response / A-F retune / V-max removed / 5,000 rpm+ dynamometer fix standard / software suits pulleys)
What size pulley is this? And i assume its the crank pulley not s/c pulley right?
