Over the last few years, we have been developing a new throttle body system for the Duratec. Initially we started with the smaller size as used on the XE, we found this was good up to a point, but we felt that a larger size throttle body would help particularly due to the big port size. Unlike the XE, which seems to only work well with the tapered throttle body & 45mm butterfly, when the XE was tested with a larger butterfly although occassionally 1 or 2 bhp was found, the torque curve would always suffer. We tested various sizes of throttle body, eventually settling on a size that gave us the best horsepower & then developed the shape of the mainifold to give the best torque characteristics.

We also incorporated what we had learnt from the Hayabusa development in that with careful positioning of the injector in relation to the butterfly, we have dramtically improved throttle response & mixture control to the point where we believe that the performance should virtually match that of an 8-injected system without the cost & installation complications. The two pre-production prototypes have been extensively tested by ourselves in a Mk2 Escort (both on the rolling road & competition use) and by Raceline on their latest development 2.3L engines for the Caterhams. They have currently seen over 305bhp on Mountune’s dyno & expect to see maybe another 10 bhp as their next dyno session by optimising the air horn length, where it is perfect for the 2.0L engine needs to be different for the 2.3L engine.

With our current development of the 2.0L engine & Raceline’s development of the 2.3L engine, we can see no reason why the engine, over the coming year, should edge closer to 315bhp.

All the components have been especially developed & are unique to the this throttle system, therefore the system is only sold as a whole kit.

We now produce 2 throttle pots, the normal Culven type & a new high spec Penny & Giles type, which is a fully sealed contactless throttle position sensor. Ideal for use in extreme conditions.

As you can see the injectors are mounted underneath the throttle body, the steep angle not only improves the mixture charactistics, but has been carefully worked out to allow for a simple flat air filter back plate.

We have incorporated o-ring grooves into the manifold (picture left), this allows for neat & simple installation and ease of removal & refitting. The port shape & size at the head face has designed to compliment our latest CNC headwork, we’ve also allowed sufficent material to allow for future development, but still keeping the casting very light

.The new throttle cable bracket (picture right), which is included in the kit is a neat simple design to compliment the cam design throttle mechanism, which allows for smooth & progressive operation of the throttle bodies.

The levers have also been designed to be easy to adjust even with the air filer back plate fitted.

We can supply multi-throttle bodies, manufactured for us by Jenvey Dynamics. They are available as long bodies with idle bleeds in the following sizes. They are dimensional the same size as Weber DCOEs.
