I'm still trying to figure out how the dyno sheet from Shelby looked so good and why I ran out of gas at about 5K RPM on the chassis dyno. It was suggested that I go up two jet sizes and then retest, which I can do, but I am also wondering if I may have another problem. I am using the original Shelby high capacity mechanical fuel pump, which they said should be sufficient for my needs. I am also going to check out the size of my fuel lines to make sure they are large enough. I have wound the engine up to close to 6K RPM while autocrossing with no problems, although it did stumble when I floored it in second gear at about 2-3K RPM (I was looking at the course, not the rev counter), but a quick down shift took care of that, so even with a ton of torque it doesn't like low RPMs. Anything I have overlooked?
Anyway, here are some numbers from the Shelby Dyno sheet:
3500 RPM: 352.8 HP 529.5 Torque 12.74 A/F 422 CFM
4000 RPM: 392.6 HP 515.5 Torque 13.07 A/F 440 CFM
4500 RPM: 456.1 HP 532.3 Torque 14.68 A/F 505 CFM
5000 RPM: 509.7 HP 535.4 Torque 15.67 A/F 570 CFM
5500 RPM: 546.3 HP 521.7 Torque 16.83 A/F 644 CFM
6000 RPM: 558.8 HP 489.1 Torque 17.60 A/F 702 CFM
Looks like the S&H air cleaner will have to go into the car show only box, along with my nifty black and yellow '65 Dealer CA license plate.
Any suggestions?
