Jenvey dynamics design, develop and manufacture motorsport fuel injection throttle bodies and induction systems. Jenvey Dynamics was founded in 1987 by successful Sports car racer Richard Jenvey to design, develop and manufacture motorsport products.
The following throttle bodies are designed to be mounted using a Weber DCOE/Dellorto DHLA style inlet manifold and are ideal for replacing these sidedraught carburettors using the existing manifold. Jenvey manufacture three different lengths of DCOE style throttle bodies. The standard and most popular length is the 118mm TB body which is the same length as a DCOE. Two shorter versions are also available for applications with limited clearance or where a longer air horn is preferred. The 30mm bodies are particularly useful for FWD applications where the inlet system is close to the bulkhead (eg CVH and Zetec E).
Single throttle bodies represent the nocompromise solution, particularly for competition use. A separate manifold is easily matched to the inlet ports, ensuring the best mixture path. This is because individual bodies can be spaced exactly to suit each port unlike DCOE style bodies, which have a fixed distance between cylinders 1 & 2 and 3 & 4 and rely on the manifold to correct any misalignment.
A limited number of inlet manifolds are available for these single throttle bodies. However where a manifold is not available, Jenvey can supply suitable flanges that can be welded to a custom manifold. Available in 40mm, 42mm and 45mm, with and withoiut injector positions.
The SFG throttle body is the basis of the bodies that have proved so successful in the World, European and British Touring Car championships. It is normally configured to supply one or more banks of cylinders via a manifold and is suitable for use with high levels of boost. The lever mechanism has two springs and gives a rising-velocity opening rate. ‘O’ rings, throttle pot clamp and fitting kits are supplied with all sets. Ideal as a performance replacement for many engines using an original single throttle body. This assembly is supplied complete with throttle linkage attached. Available in 60, 64 and 70mm bores. Height is 80mm.
