Technosqaure Nissan 370Z Infiniti G37 ECU reflash dyno test resultsTechnosquare's Nissan 370Z/Infiniti G37 Performance ECU Reflash Released (NEW VIDEO)! by Mike Kojima

Technosquare changes the factory fuel, timing, rev limit and VVEL/VTC cam control maps to get a respectable gain of 11 whp and 10 lb/ft of torque. The gains are pretty much across the board, starting at 2700 rpm and continuing until the rev limiter stops the fun. The gains are large and consistent through the entire rev range, greatly increasing the area under the power curve.

JWT Nissan 370z Pop ChargerWe Test Jim Wolf Technologies Nissan 370Z Dual Pop Charger (NEW VIDEO)! by Mike Kojima

We used a new six speed sports model Nissan 370Z with a few hundred miles on the odometer as our test subject. Before the installation of the JWT Dual POP, we baselined the car on Technosquare’s AutoDyn 30 Superflow chassis dyno. The Superflow dyno is unique in that it uses both an inertial weighted roller and an eddy current load cell to provide the working load against the engine.

Nissan 370z on Dyno

We Dyno the Nissan 370Z (2 NEW Videos)! by Mike Kojima

With Nissan claiming some awesome production power numbers for the 370Z, we decided to put the car through a dyno test to see if Nissan is able to back up their claims on actual production cars.  Our test mules are both sport model 370Zs, bone stock from the dealer with just a few hundred break in miles.

Technosquare Looking for a Nissan 370Z Development Car

As we stated in our engine technology section, we feel that a flash may make a huge performance difference with the  Nissan370Z due to the assumed bias of the VVEL system toward FTP cycle optimization, particularly in regards to the VVEL control scheduling taking the role of engine throttle control.  This means that the valve events have been compromised to fulfill compliance with parts of the FTP drive cycle instead of optimal power production and throttle response.

Nissan 370z vq37vhr engine infiniti g37

Nissan 370Z Review; Engine (VQ37VHR) by Mike Kojima

The VQ37VHR engine found in the new Nissan 370Z is a marvel of automotive engineering, powerful, clean and efficient, but from a tuner's perspective it is controversial.  Although the VQ37VHR is a work of engine design art, we predict that it will be exceedingly hard to modify beyond basic bolt-ons.  At a glance the VQ37VHR pulls some impressive numbers pumping out 332 hp @7000 rpm and 270 lb-ft of torque @5200 rpm out of 3.7 liters in the 370Z chassis.

Nissan 370Z Review; Drivetrain by Mike Kojima

The Nissan 370Z's drive train is state of the art with innovative features for both the automatic and manual versions of the transmission. These features should give the Nissan 370Z a significant performance edge over other cars in its price category.  The 370Z is available with a close-ratio 6-speed manual transmission and a close-ratio but wide gearing range 7-speed automatic transmission.

Speed in itself is not dangerous, very rapid deceleration is!  For this reason, brakes are the most important system of any high performance car. The Nissan 370Z does not disappoint in the braking department.

Nissan 370Z Suspension TechnologyNissan 370Z Review; Suspension by Mike Kojima

Thanks to, we were invited to the first public viewing of the Nissan 370Z.  While other Journalists busied themselves by jostling for a chance to photograph the outside, sit inside or eat the tasty burritos and tacos provided for the event, we got down and dirty, crawling on the ground to look at the underpinnings so we could try to get a more technical view of the car.
