Post #48: 'Anything you can to to a TQ you can do a Holley'.
Well, no actually.....
These are things you can to a TQ that you cannot do a Holley:
- change the air valve [ AV ] spring rate/adjustment
- change the AV kick
- change the AV fully open position
- remove the baffle in the secondaries. When the baffle was removed on a Hemi with a box manifold, HP increased by 30.
- change secondary blade angle @ WOT. Because of the huge 2.25" sec blades, they have a profound affect on air flow & distribution.
- the TQ is the only 4bbl that I am aware of [ don't think the QJ has this feature ] that has a mechanical link to primary jet enrichment. The step up rod on the Tee hanger. And it is also adjustable. Increasing throttle opening to a larger throttle opening has a fractional time advantage in getting additional fuel flowing for the increased load. This, coupled with the convoluted path that additional power valve fuel in a Holley has to travel, means less chance of a bog with a TQ.
