GTM Performance Engineering: Stage 2 600hp Supercharger Kits Press Release
We are pleased to announce the GTM Stage 2 Supercharger Kits line-up for the for the VQ35HR platform. The Stage 2 uses the biggest supercharger unit in the Rotrex Line-up, the C38-91. This unit is capable of flowing 82lbs/min of compressed air and is able to spin to 90,000rpm (higher rpm than any other supercharger on the market). The Rotrex supercharger’s unique traction drive also has the highest drive efficiency of any other blower with 98.4% efficiency which means less parasitic losses than traditional gear driven blowers allowing for better fuel economy when your foot isn’t buried in the throttle.
In order to fit the granddaddy of Rotrex blowers and our massive intake in the tight confines of the 350Z Engine Bay, the Stage 2 Kit comes with GTM Polyurethane Engine Mounts. The advantage of the stiffer motor mounts in addition to the clearance it affords is the increased responsiveness of the car, making it easier to maintain traction with good pedal modulation. With all the torque made by this supercharger kit, you’ll be glad you have these mounts to keep the engine from rocking around your engine bay.
Once we found room between the blower, the newly designed engine mounts, the subframe, and the fender, there was only one component left to consider: the factory exhaust manifold. The beauty of the factory manifold is that it is actually very well insulated and has heat shields to keep the under-hood temperatures low. Not ones to cross our fingers and hope for the best, we added a plethora of sensors to monitor air temperature at various points in the system.
We placed one air temperature probe in the supercharger intake, one in between the supercharger outlet and intercooler inlet and finally using the factory AIT sensors in the MAF’s after the intercooler. We logged temperatures driving around town, flogging it on the dyno and sitting in traffic in the hot Southern California summer. The result was that the proximity of the supercharger air intake to the factory exhaust manifold had no effect on IAT’s. In fact, we found out just how effective our air-to-air intercooler really is. We logged 203 degrees Fahrenheit after the Supercharger and 95 degrees after the intercooler! That’s a 108 degree drop!
To keep the whole system operating well at high horsepower levels, we are including 2.75” MAF housing in the intercooler to throttle body pipes. This prevents the MAF sensors from getting maxed out by all the airflow the C38-91 Supercharger pushes through the system. These intercooler pipes also allow the factory strut tower brace to be re-installed as well.
ROTREX SUPERCHARGES
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.
GTM Supercharger kit stages
The GTM Supercharger kit has two different Rotrex compressors to chose from: the C38-81 trim and the C38-91. Combined with our custom compressor housing we will offer three different stages .
Stage 1 up to 500 HP
Stage 1.5 up to 550 HP
Stage 2 up to 600 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 is a complete kit including fuel and engine management solutions. With that being said, we also offer an extensive range of fuel system and engine management modules to go with our Supercharger kits.
Below is a description of all the components of the GTM STG2 kit :
-Rotrex C38 supercharger
-GTM compressor housing
-GTM Supercharger Billet aluminum brackets
-GTM billet aluminum Sc pulley
-GTM supercharger cooler kit
-Rotrex Supercharger Traction fluid
-4-Ply High Resistance Nomex Silicon couplers
-Stainless Steel T-Bolt clamps
-2.5 x 10 x 24 Bar and Plate Core Intercooler Rated @ 700hp
-Polished aluminum IC Piping
-2.75” MAF housing
-GTM Oil Filter Relocation Kit
-4.5” diameter Air Intake System
-Turbosmart Bypass Valve
-Pre-made steel braided oil and P.S Supply & Return lines
-All Necessary Hardware and Installation Instructions
-GTM Custom mapped plug and play engine management for optimum engine tune and power .
-GTM Basic fuel system with Bosch EV-14 650CC Injectors and - Walbro 255 Fuel Pump .
-GTM Custom Drive belt By Bando
-GTM Heavy duty Belt idlers
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 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 than a 20 minute job
AESTHETICS : The GTM Supercharger kit maintains 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

GTM,
The car in the dyno sheets, is/was it completely stock other than the Stg 2 kit?
If not, can you share what else has been done to the car (engine, drivetrain wise)?
Also, how safe (I know this is a hard question to answer) is 13 PSI on a stock HR block?
Are you pushing customers towards a built block/beefed up transmission when they buy this kit or can these engines handle this PSI with moderate abuse?
Thanks

It's not about boost pressure. It's about cylinder pressure. Torque at the wheels is indicative of cylinder pressures. Torque is the number that matter when it comes to how much a block can handle.
Since this setup made 375wtq, it is not necessary to build the engine.
Both a Twin Turbo and a Supercharger kit are capable of making respectable numbers. It's more about which one you prefer.The 13psi run was done on a mixture of race gas and pump gas. On 91 octane and 11psi of boost, it made 470whp.

The only mod this car had was a Borla cat-back exhaust. Everything else was stock engine/drivetrain wise.

On a stock engine, it would be best to lower your horsepower goal a little. Both a Twin Turbo and a Supercharger kit are capable of making respectable numbers. It's more about which one you prefer.

1 final question, how does gas mileage take a hit?

Gtm sc kit
ASK GABE how long it took GTM to install his SC kit and all the problems he's had with it since...he was there 1-1.5 yrs getting this setup..DON'T DEAL WITH GTM....
I have taken flak in the past for my constant bashing of GTM but I don't care...hope I help someone along the way...
Yes, GTM is a hug RIPOFF! My threads are elsewhere, you can read them...Sam at GTM took my 26K for a long block/TT setup and after 1.5 yrs, he only had a shortblock finished....Got a lawyer, he gave me my **** and took the car elsewhere...In the 1 yr since then, I have lost/had stolen, over 5k in parts from GTM. Sam even built my stroker block w/o proper clearance and the engine wouldn't even turn over after it was installed by another shop....WHAT A COMPLETE A-HOLE. He had PAINTED items I asked to be ceramic coated thereby cheating out of more money..I had to recoat all the parts...He wouldn't retun my HR conversion cooling system to fit my DE and when the other shop asked for it, he replied "why should I help him"? CAUSE IT'S THE RIGHT THING TO DO MF'R!!! Never did get those parts (900) and new shop had to remake them....headlight ballast and wiring was missing, c,losed dumps for waste gates were missing starter was missing etc etc....
Don't believe the hype and BS Sam puts out....I continue to bash his azz cause I have no way of collecting my lost money/parts...(attorney wanted 5k just to begin looking in to it)...
So, this is how I extract my freaking pound of flesh sam Coksukr Zawahara...U f'd me over so until the day I die I will CONTINUE TO bash ur azz everytime I get the chance......
U need some lead n ur diet but I ain't goin' that far...
STAY AWAY FROM GTM FOLKS...LEARN A LESSON FROM ME!!
