Since we are completely done with our twin turbo system development that was released last month, We will be focusing on the the supercharged system. We are committed and planing on displaying both of our force induction system Solution for the 370Z @ sema 2009 .

Our GTM supercharger system will be utilizing the Rotrex C38 supercharger, The Key to the Rotrex supercharger's unique compactness, efficiency, low noise and reliability is 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 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 and low noise, gives Rotrex superchargers an exceptional competitive edge over any other forced induction solution.

The GTM Supercharger Will Have three different stages to offer

Stage one will come with C38-61 Trim up to 550 HP
Stage two will come with C38-71 trim up to 590 HP
Sage three will come with C38-81 trim up to 630 HP

Here is some pics of the the Rotrex C38-61

And here is some pics of the progress of the car,Enjoy the pics and more updates of the progress to follow.

Since belt slippage is one of the biggest challenges when designing a supercharger system, we feel that we have done a very good job with the amount of belt wrapped around the blower and the pulley system that we have designed for the kit.

So now we are moving to make the intake and all the piping.

Stay tuned

fuk it. the pictures aren't carrying over or my browser is being lame.. either way.. pages are Page 1, 13, and 14

Yup, no prob. GTM has disclosed all the information from the very start. They didn't really keep anything in the dark like Stillen. I'm not knocking Stillen but GTM has been very informative from day one on their project.

JB-370z · 12-16-2009, 08:09 PM

Thanks GTM!!

It appears to have worked this time.

Give us more

I feel bad for someone with a slow connection trying to access this page

I can't wait to see what the intercooler is going to look like and if it is going to be big or a baby one like HKS 350 kit which looks yucky I think a larger one would give more power too!

Togo · 12-16-2009, 08:50 PM

Thanks Mike, I don't know why that kept happening, it's not like you guys took the pictures out of your album!

I've been looking at the other SC for the 370 and the difference seems to be how fast will the Rotex wind up and make power. This will not be a problem as with the 4.08 gears in My 7 AT, First gear is over in a blink of an eye. This C-38 -61 SC is just what i need as it build power gradually. Perfect for the drag strip. when combined with Mickey Thompson drag radials 11. (305/ 35/ 18). I see no traction problems here.
I have the stillen SC on my 350 and it makes tons of power off the line, Traction with slicks is allways tricky.
Sams choice of SC is perfect for the 370 and from the charts i feel that it will make between 375 to 385 RWHP at 6 Lbs boost on an 7 AT depending on the tune and with a pulley change close to 410 or more. ( very conservitive )
Hopefully it will work with high flow cats and headers .

Santa " Sam "
will it be under my christmas tree next week.
11's here we come
Soon to be stock GTR's worst nightmare !!!!
