Danny K. owns this slick G35 coupe sitting on one of my favorite wheels, the Volk SF Challenge. He had a Vortech supercharger kit installed by a local performance shop and unfortunately the car wasn’t running right. We discovered a vacuum leak at the injector rail and fixed a few other items.

The G now runs as it should and the dyno reveals a healthy drivetrain. With 398hp/331tq to the wheels we are confident that Danny is happier now:)

Daren S. wanted to make his Infiniti G35 Journey Sedan more exciting to drive on the commute. Better breathing can improve power so we bolted on  JWT dual POP chargers and a Stillen exhaust system followed by UPREV tuning.

The POP chargers also add a very throaty intake sound 🙂

The Stillen exhaust system replaces the restrictive OEM parts and makes getting on the throttle a bit more satisfying:

On the dyno, the intake alone made a noticeable improvement in power from 260hp/235tq to 264hp/243tq at the wheels:

UPREV tuning makes efficient use of these breathing mods for a final output of 276hp/246tq! Gotta love that huge gain under both hp/tq curves:

Whoa is just as important as go and there are many options out there for improving braking performance. Instead of a full-blown big-brake kit Daren opted for a Stoptech Sport Kit:

This is a great alternative to OEM parts. When coupled with our favorite 309 pad and Stoptech 600 fluid this kit is perfect for spirited driving whether it be on your favorite mountain road or commute!

Tung N. is an auto technician at a local shop and the owner of this beautiful 370z. Tung did a very clean installation of bolt-ons himself and came to ZCG for tuning. We are glad to see that he still enjoys working on cars as a hobby!

On the dyno Rob’s UPREV tuning yielded gains of 10hp/6tq for a total of 295hp/253tq at the wheels. Power delivery was improved throughout the rev range:
