Throttle Body Adapter

Throttle Body Intake Elbow

Throttle Body Intake Elbow; As-Cast; GM LS1/LS2/Ford 5.0; 90mm Throttle Body To Square-Bore Flange; Low Profile;

This Edelbrock Low Profile elbow was designed for limited hood clearance applications. This adaptor can be used with our 29085 Victor Jr LS1 but cowl trimming and an SS hood are required. The 3848 Elbow can be used in other square bore (4150 style) manifold applications as well. It can be mounted forward, backward, or sideways on any of our Victor EFI Square bore (4150) style manifolds. Because of its low profile a one inch spacer is required for small or Big Block Chevy forward mount configurations to clear the water neck. It can be used with an LS1 80 mm (must use PN 2737 adaptor) or Edelbrock PN 3869 90mm Universal, or Ford style 75mm throttle bodies. The 3848 adaptor features: Bolt pattern fits LS1, LS2 and Ford 5.0l based throttle bodies, adapts to standard (4150 style) square bore manifolds, Fits manifold either in a forwards, backward, or sideways configuration, The throttle bore center sits 7.00" forward and only 2.00" up from the manifold 4150 flange, The throttle body points downward on a 5 Deg angle. For ultra-low applications out PN 3847 elbow sits 9.00" forward and only .56" above the flange, with a 12 Deg downward throttle body angle.

When you design and sell the best-engineered performance products in the world, you have to have a rigorous testing program. Why? Without adequate testing, there's no way to stand behind your product with confidence. That's why every product we design and sell at Edelbrock is tested and approved by Edelbrock engineers in a real world environment on state-of-the-art equipment. Our three Super Flow computerized engine dynos are capable of measuring 11 separate engine variables up to speeds of 12,000 rpm. For 2007, we added a new Super Flow SF902 engine dyno. It's fully automated and programmable to simulate various driving situations, and is equipped with WinDyn software for the very latest in testing equipment. For real-world tuning, there's our Super Flow model SF-840 eddy-current chassis dyno that can handle up to 1,000 hp at the wheels and speeds of 200 mph. When all testing is completed, the results evaluated, and the part has passed all performance criteria, then, and only then, is the product deemed ready for production. These precise testing procedures are applied to the entire Edelbrock line for performance that's guaranteed. Edelbrock test vehicles are driven by Edelbrock engineers and employees to get a "real world" feeling for the performance improvements. Our products are also tested and used by professional race car teams and drivers. Working with these talented individuals is just another extension of our research and development process so when we say "proven performance" we really mean it! Top racing teams in all forms of motorsports rely on Edelbrock to produce parts that they can count on to win races and championships. Further underscoring our commitment to the racing community, Edelbrock is the only aftermarket intake manifold manufacturer licensed by NASCAR.
