Stillen Gen 3 Nissan 370Z air intake

Stillen's Gen 3 Nissan 370Z Air Intake, Tested!

By Mike Kojima

Our test 370Z is a six-speed manual transmission sports package model equipped with a Stillen cat back exhaust, Stillen high flow cats and a Technosquare ECU reflash. For this test we used the Superflow AutoDyn 30 chassis dyno at Technosquare Inc.  As we have explained in previous tests, the AutoDyn 30 is a dyno that uses both inertial and static loading with weighted wheel rollers and an eddy current power absorber.  This is a very different method of measuring power from the common Dynojet dyno which is purely an inertial dyno.

Nissan 370Z 6-Speed Manual Transmission Parts Dyno Test, We Test Stillen's Exhaust System and High Flow Cats With Technosquare's ECU Reflash

by Mike Kojima

For our test mule, we used the Killer Bee, the yellow 370Z that was our May feature car. The Killer Bee is a sports package 6-speed manual transmission 370 that was returned to stock for our evaluation. We will be evaluating more parts on the Killer Bee in the near future so stay tuned! In stock trim the Killer Bee slung out 262 whp at 7000 rpm and 210 lb/ft of torque at 4600 rpm. The VQ37VHR engine exhibited the typical wide flat torque curve and nice linear power curve that the VQ37VHR is becoming renowned for.

Nissan 370Z VQ37VHR VVEL system

Nissan’s 370Z VQ37VHR Cylinder Head and VVEL Continually Variable Cam Timing Technology(NEW VIDEO)  by Mike Kojima

The unique VVEL system completely controls the intake valves opening and closing events. The VVEL system is exceedingly complicated using two separate rotating shafts driving links that operate eccentrics activating a valve activating reciprocating rocker arm that takes the place of the traditional cam lobe.

Dyno test 370Z Stillen exhaust, Stillen cold air intake, Beck high flow cats, Technosqaure ECU reflashNissan 370Z Auto Tranny Performance Part Dyno Thrash-a-thon!  We Test Stillen's cold air intake, exhaust, Berk high flow cats, Technosquare ECU reflash by Mike Kojima

We strove for accuracy and repeatability in our testing. We did all of our testing during one day. We used standard SAE correction. We thoroughly warmed up the VQ37VHR engine and the drivetrain by driving the car on the dyno at speed for about 10 minutes to warm the engine, transmission and differential oil (this car is equipped with Technosquare’s oil cooler kit) as well.

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.

Berk Technologies 370Z cats and downpipesBERK Technology Nissan 370Z Downpipes by Mike Bonanni

When evaluating the exhaust system on the Nissan 370Z we were amazed how restrictive it was.  The tubing diameter is tiny for an engine with the output of the VHR37.  To help address this issue we decided to start uncorking the exhaust system by evaluating a set of high flow Catalytic Converters and Downpipes from Berk Technology.

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.
