Sooo I called the guys down at Predator about converting my H2

The problem with the supercharger is it doesn?t supply enough power. Even with a supercharger, 38?s and 4.56 gears, I couldn?t leave my truck on cruise control and expect it to climb the least incline without dropping down a gear... not to mention getting 7-8 mpg on the highway.

God forbid I had to pull a 2-3K lb trailer, it was excruciating to maintain a 70mph run and I would easily get 5-6 mpg.

NOW, I can literally run 90 mph with a 4K lb trailer and pass uphill at will without dropping a gear.... all the while maintaining 17mpg.

I never did the conversion for gas mileage, I did it for the ability to drive down the highway at 85 without getting passed by every Pinto going up hill.

A supercharger works great on a stock tire sized H2 but the moment you put bigger tires on it (even with gears, it sucks) I?ve had two H2?s with liftkits, big tires and superchargers and they both were identical performance wise.

As of now, I?ve got about 7-8K miles on my conversion. Once I got the initial oddities fixed, I haven?t touched it. With my tuner on it, I?m pushing over 500 HP and over 900 ft. lbs of TQ.

The last trip I made to FL was over 1500 miles and at speeds on average of 84-88 mph (for the most part) I maintained 20.0 mpg round trip.

As far as getting it serviced, it?s as simple as taking it to a chevy dealer. Once you can get all the techs to stop checking it out, it acts and runs like an HD2500.

It was definitely a PIA to do. The actual installation wasn?t that hard, the wiring was HELL. Fortunately I didn?t have to do any of it.

My .02 worth....
