Here is what someone needs to do to get the answer. First, do a normal dyno run to get a baseline reading. Then, get a leaf blower that will blow 180 MPH. I saw one at Home Depot yesterday that advertises 180 MPH. Now, take the end of the leaf blower and duct tape it to the ram air opening to the point where it is completely airtight at the connection and there is no blow by. This should pressurize the airbox with the effect you arte looking for. The reason leaf blowers just pointed at the intake don't do much good is the blow by around the intake. In the real world, 180 mph air is force fed through the ram air intake but when you just point a blower at the intake, it has little effect unless it is completely sealed around the opening.
When doing this though, I would start the blower out at somewhat less than full power until the bike starts to climb up the RPM range. Then as the RPMs rise, increase the speed of the blower. This way, the air/fuel won't be so screwey at low RPMs. But I think this would give a true reading of just how much the ram air adds at speed.
Hey 238,
Have you seen the Hayabusa Formula One racer? Its made by Suzuki, weighs 950 lbs, has 175 hp, costs $25,000. Its not as fast as that monster you built but was pretty interesting.
