Roy A hails from Scotts Valley and we first met in 2015 when he brought his 2012 370z for UPREV tuning. It made 309hp/256tq to the wheels:
We also knew after his initial visit to ZCG that he couldn’t stay NA for long. In 2017 we made a plan to install the Stillen supercharger kit on his car.
This is the satin kit with our usual supporting mods like GTR plugs, a Z1 25-row oil cooler and the Stillen AT transmission cooler:
It made good power with 365hp/295tq at the wheels, but Roy is a guy that likes to keep turning up the boost (pun intended). At the end of 2018, we installed an air to air intercooler from SOHO Motorsports. Ecutek software was also installed which allowed us to run at Speed Density instead of MAF:
The gains were impressive, picking up almost 100hp/50tq for 465hp/343tq to the wheels:
We actually had to dial it back down after running out of injector. A full fuel system upgrade is next on the list. For now the Z is making 410hp/328tq:
Now it was time to add suspension to the mix. We installed our favorite coil-over: the KW V3.
Stock Vs KW installed front:
Rear:
SPC upper arms up front and new links at the rear.
Hotchkis sway bar set:
We also installed Roy’s new set of wheels:
These were freshly released at the time: ADVAN AVS F50 in platinum black. Sized 20×10 F 20×12 R with 275/35/20F, 305 in rear. New TPMS were installed to retain factory tire pressure readings eliminating that annoying warning light.
Enjoy The Boost, Roy and see you soon!
