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.

Nissan 370Z Killer Bee dyno test

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.

Berk Technologies 370Z cats and downpipes

Berk Technologies Nissan 370Z Downpipes

By Mike Bonnani

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.

JWT Nissan 370z Pop Charger

We 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.

Technosqaure Nissan 370Z Infiniti G37 ECU reflash dyno test results

Technosquare'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.

Technosquare Nissan 370Z oil cooler

Technosquare's Nissan oil cooler kit solves hot oil Issues

  By Mike Kojima 

Since we have actually started to work on and modify the Nissan 370Z we have come to realize that high oil temperatures have the potential to become a problem on these cars. We have recorded oil temperatures of 260 degrees plus on 370Z’s on the dyno, in brisk driving and simply in heavy traffic. Several times we had to stop dyno testing or slow down while driving to allow oil temperatures to drop.

Dyno test 370Z Stillen exhaust, Stillen cold air intake, Beck high flow cats, Technosqaure ECU reflash

Nissan 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 Sarah Forst

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.

Nissan 370Z Suspension Technology, A Look Underneath the 370Z!

By Mike Kojima

Thanks to Edmunds.com, 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.

If you are into cars, it’s inevitable that your nice shiny new ride will accumulate its share of ugly and annoying dents and dings no matter how careful you are when parking.  Even the stored garage queen is not immune to this sort of damage.  Some of you have kids, some have crowded garages full of stuff that falls over.  Some of you have spouses or SO’s that think your obsession with cars is dumb and park the car any old where when you are not around.
