STILLEN Introduces 500+HP Supercharger System for Nissan 370Z / Infiniti G37

(Costa Mesa – CA) – After more than a year of development and testing, Steve Millen Sportparts (STILLEN) is proud to announce the release of the STILLEN Supercharger System for the Nissan 370Z and Infiniti G37 with the 3.7L VQ37 engine.

This complete bolt-on kit includes everything needed to increase the factory 332 horsepower to a tire shredding 500+ horsepower on 91 octane pump fuel!

In the last update post we showed the new Intake Manifold and discussed the function of the Air-to-Water Intercooler System.  Heres some more details on the design of the Intake Manifold and the engineering behind the STILLEN VQ37 Supercharger System.

As you can see we have relocated the throttle bodies to one side of the intake manifold.  There are several reasons for this:

After the decision was made to go with the Vortech Centrifugal Supercharger, work began on developing the kit.  The engineers spent hours under the hood of our project G37 Coupe taking measurements, test fitting parts, and checking the tight clearances to see where they could put all of the necessary components.  The new VQ37 has a very unique and challenging dual throttle body intake design.  The STILLEN engineers have had great success with making big power off this design and a perfect example of that are the Generation 3 Intakes which offer up to 18 horsepower!  However, the supercharger was going to require some creative thinking and once again, the engineers have pulled it off!

Here are some pictures of the STILLEN-designed intake manifold done with our 3D CAD software, and some of the new aluminum castings just received before final machining:

STILLEN is proud to announce we are nearing completion for the Nissan 370Z / Infiniti G37 Supercharger System. As we approach production, we will be updating the progress as frequently as possible on our blog. We’ll start with the concept, and some insight into the development process.

This 3.7L supercharger development began in late 2008 and moved steadily through 2009.  We had a bit of a delay in the development while the STILLEN R35 GT-R was prepared for Targa Newfoundland, but after that car was completed it was back to business on the supercharger!  We have just started the new year in 2010 and we are excited to say the supercharger is nearly finished!  Here is a re-cap on our development and some of the engineering that went into making this kit come to life!

We ran across a thread from TitanTalk.com from one of our customers fillup who has had the STILLEN 5.6L Titan Intercooled Supercharger System installed for a while now and wanted to let everyone know his thoughts in his Titan supercharger review.

fillup gives his impressions on the kit, and how it has held up over the years:

I have now had my Supercharger for around 3 years and have managed to put 85,000 + miles on it. I have driven in every type of conditions imaginable from Living in Aspen to Working in Yuma and Spending way too much time in LA. My mileage has been 65% highway with rest in heavy urban environments.

I have owned a wide range of all motor and F/I vehicles. ranging from 360 AWHP Scooby’s to a 450+ RWHP Z’s and numerous all motor lead sleds. This however was my first modified truck.

As has been said the only thing better than power is more of it and the s/c has definitely delivered. The truck has a fairly linear torque curve with good power available from 1800 to 4500 rpm. The superman appeal of going from tire melting head jerking power to mild mannered truck is nice.

Another member RyTan adds:

Nice, I have had mine on for coming up on two years, and about 20,000 miles, and I have not had any real issues other than some belt squeak. Looks like a good installation can really be the deal maker for this add-on. Its good to hear from someone who has had a positive experience with their SC. Knew there was a risk when I put it on, but was willing to accept it. I feel that Stillen did a good job of maximizing what they could do safely without destroying the tranny, cats, etc. I am very curious to see what they have up their sleeve for the stage 3 upgrade.
