Q-jet and Holley

The air valve was probably not working properly.--- open all the way.
Or most likely you were trying to dyno it with the turbine installed on the carb.
I have experienced problems with some q-jets and the turbine. I think ours causes some air currents that the q-jet boosters/bleeds dont like. Look at your EGT's. I bet they were haywire from the Holley pulls. You might also check the fuel flow from the q-jet to the Holley. It could have been the N/S in the Q-jet not flowing enough fuel. Had that problem before, too. There are some hi-flow N/S available. Good luck
