GTM Performance Engineering: VQ37VHR Twin Supercharger System
We are pleased to announce that we are in the final stages of development of our GTM Twin Supercharger System for the VQ37. With the magnificent performance offered by the Rotrex superchargers and our great experience with them, this system will use a pair of smaller chargers to take supercharging of the VQ37 to the next level.
In addition to the 370Z, this twin supercharger kit will also be available for all the VQ35HR and VQ37VHR Infiniti vehicles as well (including those equipped with AWD). That means the G37(X), FX35/37, and EX35.
Our GTM supercharger system will be using a pair of Rotrex C30 series superchargers. Thanks to Rotrex’s patented hi-speed planetary traction drive, these superchargers are able to spin up to 120,000rpm!
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 patented 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 (up to 80%) and low noise, gives Rotrex superchargers an exceptional competitive edge over any other forced induction solution.
Here’s a sneak peek at the design drawings of our Twin Supercharger system layout:
As usual, we will be offering different stages to accommodate varying horsepower needs…all the way up to 800hp! Naturally, the higher stages will require a built motor (and built automatic transmission if applicable) to realize the horsepower potential reliably.
Below are the four different superchargers in the C30 range that are currently available and the horsepower they are rated at (times two of course).
C30-64 Trim up to 560 HP
C30-74 trim up to 600 HP
C30-84 trim up to 640 HP
C30-94 trim up to 800 HP
Here is some information from Rotrex’s website:
Here is a side by side picture comparison of the C38 (used in our current supercharger offerings) and the smaller C30 supercharger unit.
Now, as exciting as all of this is, we don’t necessarily expect to have tons of these being sold, we are mostly doing it for the fun and the challenge of being different…and just because we can!

Sounds really interesting! Once you get closer to completion, could you take the time and elaborate a bit on any potential advantages this Twin Supercharger kit would offer over a regular SC and TT.
Thanks
Thanks
