09 Aluminum Ultra Hp 950 True Hardcore
|
The engine we used for testing was set up for a Dominator carb. We learned that while the carb will physically bolt to a 4500-style intake, some Dominator intakes have a really big plenum opening, and you'll end up with a vacuum leak along the sides of the carb. For dyno testing we built a simple adapter to mount the 4150 throttle bores to the 4500 spacer on our engine. We milled the back side of the spacer to provide a shear ring around each throttle bore.
