It's a 550 inch Big Block Ford with the new Profiler (C460 improved) cyl heads, Singe 4bbl cast intake (sheetmetal elbow and converted to EFI). It put down over 1800RWHP thru a Powerglide that blew up the day after we got it off the dyno (first pass down the track). Thats also thru a 6000RPM converter, 30X10.5 slicks and a 9" 3.70 gears. Those were not power pulls, they were just get the tune sorted enough that he could go and make some passes to get it 100% at the track. From what the tuner said you can't make full power dyno pulls with something like this. We fixed the glide and it blew up again a few passes later... so we are now running an air shifted B&J 2 spd with a converter drive. Our best with the 632 inch NO2 engine was 4.39 in the 1/8th and 7.02@201mph in the 1/4. So far we have been 4.42 in the 1/8th with the new Pro Charger deal and I don't rember the excact MPH's on the 1/8th miles but the Pro Charger deal is about 4mph faster that our best with Nitrous. Keep in mind these times are in a 2900LB car on real 10.5" wide tires. Mike Murillo and Conrad Scary can run 6.70's in qualifying but they slow down or burn the motors up trying to run that fast every pass. We could run 7.0's every pass with the old NO2 set up.... as long as the car was hooked up. We are hoping once the Pro Charger combo is sorted that we will be able to better them. Here is the old NO2 motor where Jim won the NMRA World Finals last year. Conrad tried to put his qualifying tune up on it for us in the finals. Jim cut a huge light on him, then the track wouldn't hold all that turbo power down the track. Jim has some videos of the testing passes with the Pro Charger combo on his facebook. Completely different chassis reaction. Far less violent hit. Sorry to clutter up your thread. Will |
