Vortech supercharger comments

Where are You taking Your boost measurement from on the engine?

I'm less experienced with Vortech but, this is a question that should fit any kit. I like and recommend all to run a roots style supercharger as when installed they replace the intake manifold themselves. Little off topic. But, where you are getting boost measurement from can have effect. The difference in temp from air entering SP and leaving SP I'm surprised they claim that much difference in temp drop.

Unless You have an intercooler installed in loop and have forced air moving through it at idle will make temp at what ever outside ambient temp is. Once rig is rolling it would most likely drop but, no lower than what outside temp is.

My Magnuson Radix supercharger which is a water cooled aftercooler runs about 200 to 230 degrees depending on temp of air coming through grill of H2.

There may be others more familiar with your brand but, i will try to help if i can. Fill me in on if You have a intercooler or not. Where boost is being measured. Does your SP use air to air or air to water for SP cooling and any other info You can give.

Give Me model number of Your SP and i will research it more. Also Dragon my friend and partner in Hummer customizing shop along with His own tuner and muscle car customizing shop plus He paints and customizing anything. I may be able to get Him in on this one if We need to.
