After more than a year of development and testing, we are proud to announce the release of the STILLEN supercharger for the VQ37 engine. As with all R&D at STILLEN, we assessed our ultimate goals and priorities during the development phase as we planned this supercharger kit. Some of the most important factors to the development team were hood clearance, expanding power later on, CARB legality, air to water intercooler, reliability, and obviously performance. We feel that we have met or exceeded each of our goals.

When looking at different forms of forced induction the engineering team and Steve Millen decided that the best choice would be the Vortech centrifugal supercharger. We have partnered with Vortech in the past on vehicles like the Nissan Maxima and Pathfinder, Mercedes CLK430 and others. One of the great things about the Vortech supercharger is the ease of installation as well as the ability to easily add more boost and increase power. The engineers at STILLEN also wanted a supercharger system that offered little to no maintenance needs so the ultimate decision was made for the V-3 series supercharger.

The Vortech V-3 series supercharger uses a self-contained lubrication system. That means no need for running additional lines from the oil pan or separate coolers. Simply bolt on the blower and you’re good to go. Oil changes are very easy with the drain tube located on the bottom of the blower and the fill tube located on top. Changing the oil in the supercharger itself is a quick ten minute job.

One of the most important aspects of supercharging is also cooling. Superchargers build a lot of heat during the compression process so the air needs to be cooled back down before entering the engine for maximum performance. To do this we have incorporated a cast aluminum intake manifold which houses an air-to-water intercooler. During our testing we saw temperature drops of over 100 degrees of heat after the intercooler immediately before the air enters the engine. Air-to-water intercoolers have been proven to be the most efficient intercoolers available. The intercooler system uses its own separate coolant path that does not get routed in with the engine coolant. An added benefit to the air-to-water intercooler design is that the heat exchanger (mounted in front of the radiator to cool the coolant) is very thin. The Nissan 370Z has already shown that these engines have an issue with overheating. To reduce the risk of overheating we have strategically placed the heat exchanger and intakes to ensure that we have sufficient air flow to all of the vital components and additional coolers without impeding airflow to the radiator.

Airflow was another major consideration for the supercharger system. Because even stock 370Z's are seeing increased oil temperatures in just a few laps around a race course, we wanted to make sure that the heat exchanger and intakes did not interfere with our other coolers. We are very excited to confirm that the STILLEN race oil cooler, automatic transmission cooler, and power steering cooler all fit perfectly together. To bring the air into the intake path we have chosen to go with a Y-pipe designed cast aluminum intake tube that relocate the MAF sensors, retaining a “draw through” configuration. This means that the MAF sensor are located in front of the forced induction device to get an accurate reading of air volume. We chose to do this because this is what NISSAN recommends. During our many years of building superchargers for NISSAN vehicles as well as our great working relationship with NISSAN we have learned that the MAF sensor that NISSAN uses is not designed to be “blown through”, or post forced induction. Example of this are the two NISSAN vehicles that use forced induction from the factory. The NISSAN GT-R and the 300ZX. Both cars use a draw through MAF sensor setup.

At the end of the day, the most important aspect of any forced induction system is “Performance.” Performance is more than dyno numbers or horsepower claims. Performance means, how does it “perform” at a race track? How does it “perform” in daily driving conditions? These questions had to be answered during our testing so we went to El Toro air force base with our auto gearbox Infiniti G37. This car was equipped with our race oil cooler and auto trans cooler. This days testing consisted of multiple 0-140mph runs.. Hard driving on a very tight course with excessive revving and redlining. Then we parked the car for five minutes to let everything heatsoak and get really warm then immediately ran another series of 0-140 mph runs. We could not be happier with the way the car was able to handle these extreme tests. During those tests we had numerous data logging devices inside the car keeping track of a number of different data points.

Parts included in the kit:

• Vortech V-3 Series Compressor w/Pre-Assembled Laser-Cut Billet Aluminum Mounting Assembly

Hey Stillen people do you have 1/4 mile test results as to encourage us to buy this?
I love your products but I want to know how much from base test will this Charger improves my car?

I currently average 1/4 mile in 13.5's on the track

Please advise?

So apparently a safe tune for the G37 coupe was 6 psi on the GTM with Auto, I wonder if this setup will be the same. I am just wondering, we dont have auto, but I kinda feel bad for the Auto guys.

Please dont start a bashing GTM war guys, just wondered if Kyle could chime in, if they are doing somethign similar for the AT G?

Hmm ok, Yea we are most likely going to be using the Stillen S/C I just like to have all facts on the table, what is the break in process that is recommended mile wise after the install?

There really is no break in mileage.. It's good to go from day one.

Thats really good to hear, so far this kit is looking good as well as sounding good. Just waiting for my best buddy RCZ to do a dyno.:icon17: I have to say that the polished look of the charger is really looks good. Josh, do you know when the release of your other stages will be??

Awesome man, Congrats you gained around 120+ whp. Its strange though both supercharger kits are producing lower then what Stillen and Gtm had said. I mean by no means are the #'s bad, just is strange. I guess its the different weather and what not playing with the cars performance.

Well, I am not disappointed at all actually. 120+ hp in 100 degree weather is perfectly accurate as far as I'm concerned. 380 on that dyno its like 430whp on Stillen's dyno. With some cool weather, I'd say numbers stillen released are spot on.

390whp on a dynojet is like 355whp on the Mustang. I will try to get on a Dynojet one of these days to see what It can do so we can compare numbers.

Thanks! Michelin rubber is long gone... Nitto rubber is going up in flames though hahaha.

To be honest, it doesnt matter, the car is perfect right now.. comparing numbers is pointless as wel all know... Im just looking at my baseline to compare and concentrating more on the gain.

Please lets not get into a pissing fight about the GTM kit, we haven't seen 8psi third party results yet! not comparable!

This is the Stillen SC thread, theres a Stillen vs GTM thread somewhere in here. Discuss THAT there.

I recommend getting out of the parking lot of your installer (especially if it's installed at STILLEN) before doing a big smoky burn out...You don't want to be rude and leave skid marks in your shops driveway!

Kyle, are you guys gonna have a supercharged one at the track for Zcon? I'd really like to ride in it and see how it behaves tracking. I really loved the Stillen 350Z charger I had for track days, but I also installed a few vortech kits for friends on the 350z and G35 and really didn't like their driving characteristics, with the boost coming on later at the higher rpms. I really need to see how the low end is on this.

We'll have more info on ZCON soon, we're working out our presence there now. There will be supercharged Z's there, just not sure if any are hitting the track.

Nice #'s.
