Finally got around to installing a boost gauge yesterday and took the truck out for a couple of hard pulls to see what max boost is on the base H2 kit.
The only mods I have made are three 2-inch holes in the stock airbox bottom (still running stock filter - only 2800 miles on the truck) and a Magnaflow catback. Tuning is that provided with the kit. Pulley size is the 3.1 that was included with the supercharger.
Truck makes about 6.5 pounds of boost with 7 showing at the shift point. What is cool is that it offers up about 5 psi as soon as you hit the throttle.
I'm pretty happy. Now I need some dragstrip results.
