Dennis K comes from the East coast and moved to Bay Area for work. Once here he wanted to find a specialty shop to help him with his G37. He already had coil-overs and larger wheels/tires but no camber adjustment. His first visit to ZCG in October ’16 included installation of SPC F/R cambers arms and new Bridgestone S-04s tires.

 

Following a full alignment we also raised his coil-overs slightly to cope with the wonderfully smooth roads we have here in the Bay Area. Finally we added our favorite sway bars from Hotchkis, and performed some cleanup work.  As always, the performance and modifying bug kicked in. Dennis came back to us in March of this year after he had waited for his Fast Intentions cat-back exhaust to arrive:

 

A Stoptech Sport-kit rounded out the chassis upgrades. After the cat-back was installed, we change the oil, and installed several parts that Dennis had purchased online including a strut bar, grille and CF diffuser:

Thank you for letting us work on your G, Dennis!

Jason S had his 2012 370z supercharged at a performance shop in the Sacramento area. He then tracked us down to install a smaller pulley and raise the boost level followed by UPREV tuning to replace the base CAN tune.

Once we got his car into the shop we realiZed there were several things to handle before increasing the power. First, it is important to put in a colder spark plug in a car with forced induction and we used our proven GT-R units. When going from 280whp to 400whp we wanted to make sure nothing was rubbing so the following items were addressed:

All vacuum and boost lines were secured to keep them from popping off:

   

We corrected wiring at the ART pipes where a wire was touching the exhaust:

  

We corrected orientation of MAF housing:

    

The oil cooler lines were secured to prevent from rubbing anything on the front end:

  

We rectified the flaky wiring to the intercooler pump that allows water to flow into the cooler. No more on/off issues with the pump. With all of the clean-up work sorted we installed the smaller supercharger pulley and UPREV tuned the Z:

  

ZCG has performed many Stillen s/c kits and it’s a wonderful way to pump up your Z with minimal hassle and great power gains. Thank you Jason for letting us sort out your Z!

 

 

Today we bring you three cars that received UPREV tuning to maximize performance gains from common bolt-on parts like intakes and exhaust systems. Enjoy!

Sean’s 370z

Sean visited us for an ART pipe install and to correct a few issues with previous intake/exhaust installation from another shop.

 

Rob UPREV tuned the Z with great results gaining 25hp/12tq for a total of 337hp/274tq to the wheels:

 

Sean also wanted to use a new feature from UPREV called the ARC(Advanced Racing Controls) license. This add-on service to the existing UPREV Flash allows you to have adjustable launch control, burnout mode, and flat-foot shifting for $150.  This is for cars with manual transmission, VDC/cruise control. Call Rob for more details!

Nick’s 370z

 

In 2014 we UPREV tuned Nick’s 2006 black 350z…and now he has a 2010 370z so it was time for an UPREV reunion!  Nick had Stillen Gen 3 Intakes and the Fast Intention CBE w/ 18″ resonators so it was prudent to get a proper tune and extract their full potential.  With tuning we saw peak gains of 7hp/8tq for a total of 318hp/262tq to the wheels. Note the great mid-range gains:

 

 

Karl’s 350z

Nick came in to ZCG to tune his 2005 350z with bolt-ons, and we happy obliged.

 

With UPREV tuning Rob extracted 6hp/11tq for a total of 268hp/251tq. The peak numbers may not seem impressive but look at the area under the curve after tuning. There are significant gains in hp/tq throughout the rev range:

Contact us if you are interested in UPREV or ECUTEK tuning for you Nissan or Infiniti!

 

Matt M is another member of the Inconceivable Racing group and visited ZCG to supercharge his 370z Convertible. Here are a few pictures of the Stillen kit installation:

 

Matt came back to have us install some ART pipes and a Fast Intentions catback exhaust system:

 

ART pipes in place:

 

OEM vs FI exhaust system:

   

Being base model Z, Matt wanted to put slightly wider wheels on and sticky RE-71R tires for track days:

 

We love the PLX Devices gauge that neatly replaces the clock with a multi-function display to monitor vitals:

  

Finally, also installed new end links for his sway bars:

 

On the dyno we retuned with ECUTEK to maximize gains from the bolt-ons. Final numbers are 402hp/354tq to the wheels, peak gains of 32hp/24tq. After 4000rpm gains of almost +50hp/tq are seen:

Enjoy The Boost, Matt!

 

Raceworz is August 12. This is an annual event held at Sacramento Raceway which allows both show and drag racing competitions!
