Square-bore vs. spread-bore?
This guy didn’t. At least looks that way on the Vic. (Below)
A spacer can add an added dimension to the dynamics of the system that is often discounted and/or ignored or brushed off. You have the air flow path going wide to narrow with or at what ever thickness the spacer is. Sometimes a spacer is good, sometimes a spacer isn’t. The only style available is an open spacer. Most times it is around 3/4 of an inch. I have seen 4 hole spreadbore to squarebore adapters for the QJ, not the TQ. IDK if the TQ will fit due to the reduced size of the QJ’s secondary butterflies and there spacing.
