Throttle Bodies
The throttle body is responsible for allowing air to be sucked into your inlet manifold from your air filter via a butterfly valve, the position of which determines how much air is allowed though. We bore, grind and (highly) polish throttle bodies to ensure that there are minimal obstructions to the passage of air though them. Good improvements to engine pick-up can be made by working your throttle body, which is a very cost-effective way of removing flat spots, improving driving enjoyment and improving engine performance.
Our standard specification:
- Inlet ground and bell-mouthed for maximum air intake speed
- Casting marks removed
- Boring marks smoothed into body for unobstructed air flow
- All machine work and butterfly plate highly polished
- Low-profile screws fitted to butterfly plate
- Butterfly adjusted to horizontal position to allow more air to flow when fully open
- Chemically cleaned and lubricated with mating surface prepared for fitting
We do not 'half' spindles like other suppliers of similar throttle bodies - something that frequently causes the spindle to snap (causing extensive engine damage). However, we can knife-edge the leading edge of the butterfly for race applications where a fast idle speed is not a concern.
