Vortech supercharger comments

[Michael Baker]

I installed the supercharger on my H2 two years ago, but I have only recently installed the gauges necessary to monitor how it performs.

The boost gauge was showing a maximum boost pressure of 4-5 psi when flooring the accelerator. According to Vortech, it should reach 8 psi, but they said that maybe the max of 4-5 is due to decreased back pressure on my vehicle as a result of installing headers and removing the catalytic converters. I purchased a new compressor pulley two sizes smaller than the stock one, and this has now resulted in boost pressure of 8-10 psi when flooring the accelerator pedal.

I installed gauges to measure temperature of the air entering and leaving the charger cooler. To my surprise the difference is only 20 degrees ? the temperature drops from 150 to 130. On their website Vortech claim a temperature drop of 100 degrees. This will be the focus of my attention now. I am thinking about replacing and re-routing the rubber tubing as it seems to me that it is constricted when it passes to the font of the car and on to the radiator (following Vortech?s installation instruction route). I have already replaced the flimsy plastic reservoir with a custom made aluminum one, after breaking no less than TWO of them ? if you do install the Vortech, make sure that the blue cap of the reservoir does not touch the bottom of the hood when it is closed. I am thinking about replacing the reservoir with one much bigger (taller and wider) in the same position.

Any comments/similar experiences would be welcome.
