engine dyno was a superflow, rear wheel dyno was a dynojet. Run condtions was 98.5 degrees 28.97 in-HG Humidity was 15% SAE 1.05 I know that the outside air temp hurts hp. but i didnt think it would drop that much lol dyno guy did a great job with how he set it up and was very professional he just told me it was my gears that was making the driveline percentage so big. Engine stops makeing power around 4,500 and both dyno sheets prove that, and Yes i agree that when the engine was dynoed there was ideal condtions with no drag on it, same headers, same carb, same dizzy only thing that was different was it was set up with MSD crank trigger and race gas at the time. Just trying to find out about if the dyno is accurate or if i can gain some numbers somewhere thanks all
