Looking to extract more horsepower and torque from your G37 Sedan How does around 400HP To The Wheels Grab You
Add a dose of torque, better-than-stock heat management and airflow, 50 state emissions compliance and near stock fuel economy at low RPM. Now you've got the formula for superchargers done the STILLEN way. Continuing with the success of the STILLEN supercharger system for the Nissan VQ37HR (G37), STILLEN is proud to offer the VQ37HR dual throttle body G37 supercharger kit. The VQ37HR Supercharger shares most of the same components found in the VQ37 kit, and designed as a direct bolt-on to the 3.5L VQ37HR.

We're talking driveable horsepower too, suitable for daily drivers, canyon carvers and track days.

 

What does 'driveable' mean

Take an unsuspecting passenger for a low RPM cruise around town in your STILLEN supercharged Nissan G37. Keep a light touch on the gas pedal and they might be fooled into thinking there's a bone stock motor under the hood.

They won't suspect a thing....until you hit the town limit sign and crack the throttle wide open.

Scenery gets blurry-in-a-hurry as the centrifugal Vortech blower spins up to hyperspeed with a telltale hiss. The STILLEN designed and built intake manifold sucks in cubic yards of cool air. The remapped ECU fuel management module jacks the boosted fuel pump to inject the precise amount of high octane cocktail into the maelstrom.

Your right foot is orchestrating a symphony of controlled violence that delivers a linear, bottomless powerband. If you can peel your head off the headrest to sneak a glance at your passenger you'll see instant enlightenment and heavy G's at work.

 

A YEAR IN THE MAKING

You might think it all sounds like witchcraft. But there are no spells and potions involved in creating this enhanced driving experience. Designing this supercharger system for the 370Z involved precision engineering and innovative problem solving - a STILLEN specialty!

Much of the year-long development and testing process surrounded the ECU fuel management settings. STILLEN engineers remapped the ECU fuel management settings for the supercharger system to manage the improved airflow, operating temps and huge power gains, all while achieving 50 state emissions compliance**.

The complete supercharger kit includes larger injectors and a new fuel pump to match the remapped factory ECU.

 

A BULLETPROOF BUILD

By redesigning the intake manifold we were able to incorporate the intercooler inside the manifold, thus allowing us to cool the air charge immediately before the air enters the engine. Additionally, the front mounted heat exchanger does not block the airflow supplying cool air to other vital coolers such as the radiator, engine oil cooler, transmission cooler, power steering cooler or the A/C condenser. Because water is 4 times more efficient at dissipating heat than air, we are able to utilize a more compact heat exchanger to cool the water.

The V-3 features a self-contained oiling system and quiet V-belt design, with plenty of additional boost capability for those wanting even more power down the road.

STILLEN took extreme care in designing this system, ensuring that all additional coolers (oil, transmission, power steering, etc) would work with the intercooler system, as the Nissan VQ37 engine is prone to high oil temperatures unless properly cooled.

At all levels of development the system was tested, both for street drivability and reliability under normal traffic and freeway conditions. Stillen drivers flogged the test car at El Toro Air Base, with repeated 140+ mph runs and hard driving on tight courses with excessive revving and redlining. Testing included extensive monitoring of all pertinent air and fluid temperatures.

2 OPTIONS

 

WITH CABLE OPTION

To tune these supercharger systems STILLEN works with UPRev software. This software requires a license and a cable to load the tune into the vehicle's ECU. The With Cable option is designed for customers who may not live near an UPrev certified tuner or for a dealership who is completing the installation. This is also a great solution for the DIY guy looking to install the kit in his garage.

 

WITHOUT CABLE OPTION

The "without cable" option is supplied with all of the hardware and the tune. This solution is good for someone who is working with an UPrev pro tuner that already has the licenses and loading cable in their facility. This way you don't need to pay extra for something you might already have access to. Either way, the tune is the same.

 

STRAIGHT FORWARD INSTALLATION

One of the hallmarks of a STILLEN supercharger is ease of installation. Much of the assembly of the kit is completed here at STILLEN before we pack and ship your supercharger. The main supercharger unit is pre-assembled to the laser-cut billet aluminum mounting brackets. Installation is very straight forward, including detailed step-by-step instructions. Typical install time for a competent shop is 12 hours.

Large breed approved
Color: Blue
these incredible aggressive chew toys – they've seriously been a game-changer for my pups! I know it's a bit late, but better late than never, right? I've got a couple of power chewers at home, a Rottweiler and a Labrador, and anyone with big dogs knows the struggle of finding toys that actually last. These bad boys have been in constant rotation for over a year now, and I'm genuinely impressed by their resilience. They're incredibly tough! Funnily enough, we originally had three, but now we're down to just one. The others aren't broken, though – I'm pretty sure my dogs just loved them so much they've hidden them away in some secret stash, as they tend to do with their favorite treasures! Beyond just being durable, these toys have been a massive help with their training. They’re fantastic for redirecting all that enthusiastic chewing away from my furniture and shoes, which, let's be honest, is a huge win for any pet parent! Considering how long they've held up to some serious chomping, the price point is absolutely spot on. You definitely get great value for your money.watch your toe they are heavy. If you've got a dog that's a champion chewer, you absolutely need to try these out. They're a lifesaver!

Durable chew toy.
Color: Blue
My dog loves these. She chews on them a lot. She seems to like the different shapes. She is part Pit and an aggressive chewer. These chew toys last a long time. And I love the three pack so if we lose one, we always have a spare.

Decent durability for the price
Color: Blue
Bought a bunch of these for a dog shelter and have to say - decent for the price of you have aggressive chewers. All of the toys are still going 6+ months later, even with the strongest jawed pitty mix. Does get torn up at the ends but can easily be sanded down for a longer lasting toy, unlike some other hard toys with material not meant for sanding. The antler and ring seem to be favorites. The antler even has a divot so you can put soft treats in it or peanut butter and freeze it for a more interactive experience. Some came with a strong beef/liver smell but not overwhelming or off-putting. They are hefty without being too heavy, less likely to damage floors. Overall a good purchase
