Dyno results - Tquad vs Holley vs Qjet - tuning issue, too rich
While not actually knowing or care to look very hard at this carb myself, just happy to have one, now that it is apart, I have come to the conclusion that this is the bigger 1,000 cfm unit since it has dead straight primary barrels with absolutely zero venturi shape within them. This is what I was told as the hallmark of the 1,000 cfm TQ.
A few more pictures of notable items of the race TQ below. First picture is where production TQ’s have a cam lobe to insure the metering rod tree will rise up to richness up the air and fuel mixture. There is none on the race TQ.
Next picture, you’ll notice the maching of the bowl is different with the most notable missing fuel well that can leak fuel.
Last is the downward facing fuel inlet. At first, I tried a regular TQ fitting, wrong answer. Summit racing actually provided the answer and parts, it is first a Rochester fitting into the aluminum. Surprise! Then the TQ fuel fitting. I’ll drill that out to 3/8 later. (Just wanna be sure we have fuel!)
