There are a couple of people who have tried this and I'm sure it can be made to work but pump gas is not going to cut it - Supercharging means you have too much dynamic compression.I had a different idea - have a super charger, but only run it at the bottom 2000 RPM or so.
FWIW, Hitchcocks online catalog (page 92) now claims that they have put in more work on the power commander and seemingly ironed out the bugs, and it comes with a 20% power increase.
So, you have to take these marketing claims of "more hp" with a grain of salt, really. They might give more power, but they can only gain back whatever poor tuning lost with the factory tuned ECU. Or, adjusting the mixture for the added air flow that the free-flow stuff provided. It's getting more air into the engine, and then getting the A/F ratio set right for that larger amount of air volume that actually makes more power.
let's have a comparison of the stock head flow of "old vs new".The flow data for the stock Iron Barrel head:CFM flow @ 28" water column@ .050" lift = 28.7@ .100" lift = 53.2@ .150" lift = 83.8Flow data for stock UCE head.CFM flow @ 28" water column.@ .050" lift = 35.9@ .100" lift = 65.338@ .150" lift = 89.09In this comparison, it appears evident that the Iron Barrel would respond more to higher lift than the UCE...............the UCE head, so it would respond more to the higher lifts which we have planned for it......
