Another change was I'm using a large air-water in car intercooler. First pass was an 8.8 and I was pretty happy but upon reviewing the FAST data log I noticed the tune was way off. The tune I was using was for my F2 Procharger which I'd taken off the car because It was throwing belts. Well, the recorded data indicated I was running very rich and not running enough timing so I corrected those 2 areas using my laptop. Next pass was an 8.44 at 159mph then I backed it up with an 8.42 at just under 160mph--awesome for a D2 procharger with a rib belt. The thing is I have a smaller pulley for the D2 which in the past has been good for another 3 tenth's. I think next time I'll try it.
