One of the members of the SVTOA Tampa Bay installed a JRSC in his SVTF. He said it took about 15 hours. He had to call Jackson Racing for clearification on a couple of steps in the installation documents. As of a couple of weeks ago he was trying to dial in the fuel/air mix because it was running too rich. He also has a CAI installed that sounds like a vacuum cleaner now. You can hear the blades of the SC turning thru the intake.
