GTM Performance Engineering 370Z SUPERCHARGER KIT PRESS RELEASE
 

We are please to announce the GTM supercharger system for the 370Z. Our GTM supercharger system will be utilizing the Rotrex C38 supercharger, The Key to the Rotrex supercharger is unique compactness, efficiency, low noise and reliability and its state of the art traction drive technology.

Great speeds and low noise are just some of the advantages of traction drives over traditional gear transmissions. Traction drives transmit power through friction forces between its rolling elements.

The Rotrex traction drive uses an elastic annulus with a small pre-span to secure contact between the roller planets and the sun shaft with a reasonable force. The patented "ramp effect" increases efficiency and reliability in the transmission by regulating the torque transfer capability on demand through self-adjusting planet geometry.

To enhance performance, the Rotrex traction drive uses a special traction fluid. These fluids are a new family of synthetic hydrocarbon oils and greases offering a series of unique performance advantages. Developed specially for its use in Rotrex superchargers, the SX100 momentarily increases viscosity under high surface pressure, enhancing the traction drive performance by securing the optimum friction between rolling elements while cooling and protecting the system.

This traction drive combined with the latest technology in centrifugal compression, characterized by high adiabatic efficiency and low noise, gives Rotrex superchargers an exceptional competitive edge over any other forced induction solution.

The GTM Supercharger kit will Have four different Rotrex compressors to chose from: C38-61 Trim,C38-71 trim, C38-81 trim,C38-91. Combined with our custom compressor housing we will offer three different stages .

Stage zero up to 450 HP (carb approval pending)
Stage one up to 500 HP
Stage two up to 525 HP
Stage three up to 550 HP

All of our Supercharger kits are available in two forms. The tuner kit form, so the professional and the end user have the flexibility of choosing what ever fuel and engine management they may desire and feel comfortable using. The second option being a complete kit including fuel and engine management solutions. With that being said, GTM will also offer an extensive range of fuel system and engine management modules to go with our Supercharger kits.

Some Key points about the GTM supercharger kit

After literally installing and tuning every supercharger kit available for the VQ platform and seeing their short comings, we got the inspiration to develop a kit superior to all others. Problems with the other kits that we wanted to address with our own include: not supplying a descent amount of power, belt breakage and slippage, obnoxious gear lash noises, limited power expansion and lack of the OEM look. Some of the key things we did to achieve our goal are:

SUPERCHARGER NOISE : We chose the Rotrex unit, a very QUIET supercharger compared to anything else on the market .

SUPERCHARGER BRACKETS : Our supercharger bracket is 3 dimensional made out of of thick billet aluminum to prevent any flexing, we also mounted the supercharger unit as close as possible to the engine to limit the amount of flex possible, as well as keep the belt length down between pulleys.

BELT AND TENSIONER DESIGN : We have over 80% belt wrap on our supercharger's pulley and with utilizing the factory automatic belt tensioner over or under tightening is simply not possible.

POWER EXPANSION : Changing the pulley on the super charger is less then 20 mints job

AESTHETICS : The GTM Supercharger kit maintain the clean oem look

ENGINE MANAGEMENT: With using the GTM flash we are to able to maintain the OEM drive ability so the car will run like stock, only with a lot more power .

POWER DELIVERY : The GTM supercharger is best bang for the Buck out of the box

***Update 1/4/12***

We have the CARB Test Letter in hand! This means that CARB has approved the components in the kit and they have everything they need with the exception of final emissions testing. We are *this* close to getting approval.

Simply awesome, Sam! Incredible job!:tup:

so ******* tired, i'm glad it is done .

Sam

PM sent.

ok now I really want that proposal from you

Incredible piece of work! That's just a work of art. Sam, what will the price difference be between the Stage 1, 2, and 3? I'm interested in the Stage 3 system, including full exhaust. Do you recommend your 2.5" or 3" exhaust? Will this setup work with long tube headers? Yes, lots of questions.

So I am in at the pre order price right? Even thought i will ont be getting ti installed by you until may/june? Do you need a deposit?

plus one on the LTH as I have them ordered.

hmm, I must have missed when Stage 3 turned from the 81 trim to the 91 trim.

Sam, take a nap :tup:

So does the intro pricing apply to all trims?

Good question.

Also, I noticed that the C38-91 won't be out until late spring/early summer of 2010. Any comment?

From Rotrex A/S

FWIW, I'm interested in the Stage Zero turn-key kit. $4995 for ~420whp is a great deal, IMO. Interested on when the kit would actually be available and what kind of pricing I'd expect if I ordered after the introductory offer period.

... another good question. I won't be ready to go FI for some time.
