I now see that both are supercharged and the 400 charger i s slightly overdriven for more boost. What confused me was in the origin al post it said full rpm. I wonder why you didn't get 30" then.. A gear driven positive displacement blower should put out a given amount of boo st at a given rpm. I am hoping to fly over Fri to see ya. Call me with a time... Seeya.
