Re: bog
Although most bogs are carburetor related, many aren't. Just this past week a racer called with the same problem as described and although he had two other builders work on his Q-Jet he wanted me to look at it. Knowing there wasn't enough time because he wanted to go to Joliet, I told him if he would pay the shipping that I would let him use one of mine for the weekend. He called today to say that the problem still exsisted and this made him look elsewhere. He found that his intake gasket was leaking on the bottom side. This is not an uncommon scenario in the carburetor business. I've had racers who were convinced they had a carb issue only to find out they had a bad ground wire on the fuel pump, an ignition problem, epoxy came out of the intake, insufficient fuel delievery, etc. As stated earlier, getting a Q-Jet to work off a two-step can sometimes be challenging. Whenever a rev-limiter is used, a rich condition occurs when the button is released. I've seen this on the graphs of my customers who have the RacePacs with wide-band oxygen sensors. It will drop down on some cars to 10.5. Once this condition is corrected the car will leave the line a lot cleaner. Bill and Dave, you could very well have carb issues but don't rule out other areas.Finally, I must say that I enjoyed Mr. Santos' comments especially where he said no two Q-Jets are the same. Amen brother! I too am still learning and keep trying to build a better mouse trap. Danny
