What started as custom prototype manifold for us by CFE Racing has now evolved into an off-the-shelf part, PN BMF-MN-10001. The shorter runners help produce less torque at the bottom end, making it an excellent choice for anyone competing on small tires, yet it still produces tremendous upper-rpm horsepower on the big end. Expect to spend $2,600 for a duplicate and that includes the dual 4500 flange up top with the nitrous bungs. It's becoming a popular choice among the nitrous outlaw 10.5 guys and other tire-limited classes, but it's important to note that it's not recommended for any motors smaller than 572ci. The burst panel is a Wilson Manifold piece we later purchased and installed as a precaution for a potential nitrous backfire-it happened once, and let's say it's well worth the investment; it saved us a lot of time, money, and serious aggravation.
