We are pleased to announce the GTM Stage 1.5 Supercharger Kit for the 370Z. The Stage 1.5 uses the same supercharger head unit as our Stage 1 Kit (the Rotrex C38-81) with the intake system of our Stage 2 Kit. This enables maximum horsepower to be extracted from the smaller supercharger while still delivering exceptional boost response and bottom end torque. 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.Features:
- We chose the Rotrex unit, a very QUIET supercharger compared to anything else on the market .
- 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.
- 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.
- Changing the pulley on the super charger is less then a 20 minute job
- 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.
