Contour Enthusiasts Group Archives Forums Modifications Zetec Maintenance Optimized TB on Zetec?

Agreed andenthal, once I see one up close, I'll begin looking for swap possabilities in local scrap yards. Until then, I want to try the same service I do for the Duratecs, only apply it to the Zetecs as a cheaper/easier solution.

Pollo, optimizing is removing or reducing any air flow obstruction on the stock TB. For the SVT and non-SVT Duratec TBs, that includes knife edging the entrance lip, smoothing the throttle plate bore lip, knife edging the throttle plate, removing the front half of the throttle plate bar, countersinking new screws, and a light polish. This not only increases the cross sectional area for better total air flow, but also speeds up air speed by making much smoother transitions.
