438whp, for 5800, how ya like them apples?

okay , im convinced. i want a nismo with this NOW

 

dp

 

so what psi is this at though? it says small pulley so i dont know if im impressed yet, def. good numbers for a stock block setup but just hope it didnt take alot to get there

 

I think I'm a little aroused yet frightened..... strange!?!

 

Hmm , i assumed it was a factory deal like the 350 was... if so i am sooo sold

why cant i post that?

 

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
• (6) 600CC Fuel Injectors
• ECU Based Tuning Device
• High Output Fuel Pump
• Air-to-Water Intercooler System (Intercooler, Heat Exchanger, Pump, Hoses, Mounting Brackets)
• Polished Aluminum Intake Charge Pipe
• Cast Aluminum Intake Manifold
• Cold Air Intake Y-Pipe w/Draw Through MAF Sensor Bosses (as recommended by NISSAN)
• Genuine K&N Intake Filters

Recommended installation time of 10-12 hours

Pre-order customers will be mailed the tuning device first with detailed instructions on how to prepare the car for the supercharger. By pulling your tune ahead of time we are able to prepare your tune so that you're ready when the supercharger ships.

Supercharger kit shipping ETA : Mid-to-Late April 2010

 

Very nice work. Still sucks having 100hp diff in HP and TQ

 

Stillen hit it out of the ballpark with this one, vastly improved on their 350Z offering. The 100 difference between hp and tq is not a big deal, keep in mind that this is "safe" territory and that this is only their base CARB boost pressure. They will be offering 3 stages, up to 10psi I assume, meaning 500+whp/400+ft/lbs can be obtained. Now the rest of you, trade in that aging 350, get a 370, and turn up the boost!

 

And for those of you that just refuse to let go of that Z33, Stillen is going to be offering this same kit for the HR folks!

 

good info man

 

From the looks of it you lose your Strut Tower Bar. I would wait to see GTM's kit.

 

you dont lose it. I went over to the 370 website and read up about it and they just havnt installed it back

 

Very nice work! Look forward to the results for the 07-08 z's if there are any.

 

That would be kind of pointless for us HR owners, since this kit is basically the same for both engines, and both the HR and VHR could probably handle the same amount of boost.

$5,800 isn't bad though

 

There is some truth there, but Kyle said the HR kit is going to take awhile, they have to design another intake manifold, and bracketry. The numbers for the VHR will be slightly higher bc of the .2L extra of displacement as well. Another thing to take into consideration is that the 370 is also quite a bit lighter, so the additional power will have more of an impact.

 

so this dyno right here is at 7.9 psi? thats not bad..it took my DE Z 10 psi on a vortech kit to see that horsepower number but i do make more torque than that 370...dyno's are dyno's and completely different kits so cant compare that, i just wanted to make sure that is the psi. # it took to get it there...Id like to know how safe that tune is and what timing and a/f is at and all..

still though i have not found the answer to if say i bought this complete kit here in NY for a 370 how would i do any tuning with it? what software is it or form of ems?...i woult not rely on a mail in reflash like it seems..i would only rely on that to get to a dyno and be properly tuned..every car is different and different elevations and weather conditions and all that play a factor

 

check the post on the 370 site, its only at 7.9psi, this is only the CARB kit as well, keep that in mind. This is emissions friendly power, the race kit is going to make some stupid juice.
