Well, I made it a second time to the track last weekend. My first trip was disappointing. The best I could do was a 16.9. I found that my q-jet's secondaries were not opening. This was easy fixed once I discovered the problem.
This time I was hoping for better, and it did get that. My first run was with the air cleaner and exhaust in place. It was a poorly driven run (I'm new) but I managed a 16.7. So I felt low 16's were no problem once I opened the AC and exhaust.
The next run was going great until about half track. The engine died. I let off, it came back, but died again once I got back on it. Kinda like it was sucking air in the gas tank.
So I put more fuel in, ran it again, same thing. This time I noticed the boost was max'ing at 12 psi. I still have the factory, non-adjustable actautor which should be set to ~9. Figuring I had a blown actuator, I gave up for the day.
Last night I took off the actuator. It's not blown, my boost is creeping up. Since I had it off, I put on an adjustable actuator. It still creeps.
If it creeps to about 11 psi, the motor starts stumbling again. Maybe a bad fuel pump? So I have a couple of new problems to sort out.
