A few months back, I went with a friend to Anderson Ford Motorsport's dyno for a tune. Rick Anderson himself was out there watching things over, and to try to make things more consistent, he would lay shop rags on the upper intake, and inlet tube and then spray them with water from a spray nozzle. Then he would monitor the temp with a lazer thermometer and do all the pulls with the intake at the same temp.
So if you want to get the most out of your session, I would reccomend doing the pulls at the same temperature to really see how the other changes effect the power.
My guess for the 90 (cause I used to have almost the exact same combo) is 250rwhp/295ft-lbs. And a compete shot in the dark 275rwhp for the cobra.
good luck
oh and, jimberg, I've heard that about the mustang computer compensating for fuel pressure, and I have never understood how it can do that? It just seems like the only thing that could actually change the pressure is the regulator, which is completely mechanically driven (ie vacuum). Can the ECU somehow control it through a signal to the pump?
