Lightweight, strong and accurate is the perfect motorsport design. To ensure the
throttle plates have a perfect interface with the bore of the throttle body, the
throttle body wall thickness is increased in this area. Greater wall thickness gives
a more stable base when machining so improves tolerances and gives more consistent
throttle body manufacture. Towards the atmosphere end of the bodies this exacting
precision is no longer required, so the wall is thinned to reduce weight. Maximising
performance and minimising weight.
Linkage fitting choices.
Because every engine bay is different.
The side-pull throttle cable linkage can be fitted in 4 different positions to allow
you clearance for other parts of the engine such as alternators. Just 2 fasteners
remove and refit the linkage in any of these 4 positions so you can leave this decision
until you have the throttle bodies mounted on the engine.
Sensor reliability from basic engineering design principals.
The commonly used throttle position sensor ‘D’ drive requires the sensor to be absolute
centred on the spindle else the tight interference fit will force the centre section
of the sensor round through odd angles, causing wear and early failure of the sensor.
To get round this problem, users upgrade to expensive “contactless” sensors. But
that is an expensive and electronically complex way of solving a simple mechanical
problem… The Omex sensor is spigot fitted to ensure correct alignment, and uses an
‘I’ drive which does not need a tight fit so the sensor is free to rotate exactly
as it is designed to. Two basic pieces of engineering design that together improve
reliability at no extra cost. The sensor used by Omex is a standard OE sensor backed-up
by hundreds of thousands of units being tested on the road for hundreds of millions
Easy tool use for better tool use.
Years of fitting throttle bodies has shown us that ease of use gives performance.
Why? If you can adjust something easily, you will adjust it properly. The Omex throttle
bodies have been designed to allow easy tool access.
Compatible with motorsport standard airfilters.
Do you prefer foam filters? Cotton gauze filters? Mesh on the outside? Metal end
plates? You can fit any of them. For compatibility with the huge range of aftermarket
DCOE / DHLA carburettor airfilter setups, the Omex throttle bodies have the same
bolt flanges as the DCOE carburettor.
Neat solutions for tidy wiring installation.
Omex’s unique position of being an electronics and wiring harness manufacturer as
well as a throttle body manufacturer allows us to sometimes see things from a better
overall perspective. We hate seeing wiring harnesses tied to fuel rails, so the Omex
throttle bodies allow the unused set of linkage bosses to be used for mounting the
wiring harness. This always keeps the wiring away from the moving parts of the linkage
too; when the linkage is above the throttle bodies the wiring is underneath, and
when the linkage is below the wiring is above. A simple solution that improves the
look of the engine bay instantly.
High volume fuel rail.
High flow injectors in high performance engines cause pressure pulsing in the fuel
rail. A larger volume of fuel reduces this pulsing, ensuring even fuel flow across
