Edelbrock Throttle Body Intake Elbows

Ultra Low Profile Elbow #3847 is designed to fit our Victor Jr. LS1 EFI manifold #29085 and is ideal for tight engine compartments. The throttle bore center sits 9.00" forward and only 0.56" up from the manifold mounting flange. Includes throttle body adapter plate #2737 for use with LS1 throttle bodies. We recommend Edelbrock 90mm throttle body #3869 for optimum performance. Low Profile Elbow #3848 has a throttle body bore center 7.00" forward and 2.00" above the manifold flange. Designed for use with Edelbrock Pro-Flo XT throttle bodies #3869/#38693/#3818/#38183, GM and Ford 90mm throttle bodies.

These elbows are designed for use in high hp race applications. An internal divider optimizes flow distribution to all ports of the manifold by reducing turbulence. High Flow Elbow #3849 is an ultra high flow version which measures 4.50" from flange to throttle body centerline (7.75" overall height). During flow testing this elbow provided up to 1,050 cfm with a 90mm throttle body and 1,150 cfm with a 95mm throttle body. Does not accept LS1 throttle bodies. Intake Elbow #3814 has a universal bolt pattern and is the best way to adapt a single throttle body to a Dominator® 4500 style flange EFI manifold without sacrificing air flow. The throttle body flange accepts 90-95mm LS1, LS2 and Ford 5.0L based throttle bodies. Intake Elbow #3815 is also engineered for use on a Dominator 4500 style flange manifold. It has a 120mm opening for maximum flow and is capable of over 1,400 naturally aspirated hp. The throttle body flange uses a 4.250" square bolt pattern. This elbow flows 1,800 cfm @ 20.5 in H2O. Includes a universal throttle bracket.
