Product Details

The Windsor IDF kit

Some throttle systems fire the injector from the outside of the manifold across the port which results in poor idle characteristics and also a bad stumble off idle and under light acceleration.

Our new series II IDF throttle bodies have the Injector located inboard to point the injector through the port and directly at the back of the inlet valve. This gives a far superior idle and much sharper throttle response.

It also improves emissions allowing a much leaner idle mixture & improving economy.

The one piece manifold has a vacuum plenum underneath for the brake booster and idle control.

Our new Pro-Series linkage set incorporates the throttle stops, idle controls, lever arms and joiner/balancer all in one. It also features a single screw adjustment for calibrating front to rear throttle shafts.

The bell crank has a fully indexable eccentric cable pulley that enables good slow speed drivability and still attain full throttle the geometry in the bell crank also assist this.

The Pro Street IDF II throttle bodies have the following features

They are manufactured from 601 Cast aluminum and are heat treated before being CNC machined.

The butterflies are measured for each bore & precision machined to a 0.0005" tolerance.

Butterflies are secured to centreless ground brass shafts with split screws to ensure reliability and serviceability.

All are fitted with bearings rather than bushes to eliminate axial shaft movement.

Housing to shaft lip seals behind bearings for extra sealing under high vacuum

Idle by pass air bleed screws for super smooth idle and to aid emissions tuning.

O'ring seals on lower mounting faces.

Available in 50mm bores currently 52mm available soon

6 degree butterfly angle from 2008 on
