JGYCustoms Project Cars/Current Customer's Cars

Ron brought his 2012 370z Roadster back to JGY for some more work. The Stillen Supercharger had started making a strange noise, so he wanted JGY to diagnose and repair any issues. He also wanted new brakes and lines added to the 370z.

JGY redyno'd the car. Jason's second program was reloaded before the CEL delete was created. The power went back up to about 450HP, and the PSI was close. But, JGY found water entry into the Supercharger - the vent plug was open to the vent hole in the hood.


The Supercharger was removed and sent to Vortech for a major repair. A gearcase/cover was also ordered from Vortech.

And, we're good to go.

JGY worked with Stillen to progress the program and got a great gain in power in the curve, some spots making over 30HP more at the same RPM as before, netting 469HP and 350tq.
