David, good info...now ya gotta figure out wha's causing the A/F ratio to go rich...maybe the float level for the secondaries is too high, and there's a momentary rich condition when they open? Let us know what you find. Any Holley Gurus out there?

Craig, on the comparo between the mustang and the RX7...the only points where the comparison would be in line with Johnny's quote would be...the rates of acceleration during the few seconds where the Mustang was running through its peak torque of 2750, and the Mazda through its peak torque of 9000 RPM, and geared appropriately, right? So, if you compare both the Mustang and the Mazda at 2450 RPM, the Mustang will out-pull the Mazda; make the comparison with the Mustang and the Mazda at 9000 RPM, and the Mazda not only out-pulls the Mustang, it will probably have to pull it back to the trailer, hahaha, since the 'stang will be "broke".
Oh, well, theory makes me dizzy. HELP!
David, didn't mean to hijack your thread, are you going back to the dyno?
