GTM Stage 1.5 Supercharger instruction manual

theDreamer

Stage 1.5 & 2 intake pipe to the Rotrex unit is now a Vband that bolts directly to the Rotrex unit. You basically need to sets of hands, one under the car and one above to guide it in nicely.

The major difference is that one intake piece, where the stage 1 had a piece with an over 90 degree bend which did not allow you to run anymore air into the Rotrex unit. I know this because I had the smallest pulley possible on my car and barely made over 8PSI, it was an airflow restriction. The piece of pipe in the lower left corner of this photo is the intake piece which takes the 2 intake filters into 1 and then bends around and into the Rotrex unit. Where with the Stage 1.5/2 you have a "straight" piece of pipe.
