Obvious as it is, Iím installing an ED XR8 sprint upper and lower inlet manifold onto my 165 windsor. I was removing the sprint throttle body from the inlet yesterday and the urge to know exactly what the following photographed component was got the better of me. I thought Iíd post to
(a) determine what it is and how it works and
(b) ask whether Iíd be better off without it (well more specifically blocking the lines etc going in and out of it)
My AU V8 friends remark ďwhat the hellís thatĒ when casting an eye over my machine so itís obviously an e-series characteristic. When I cracked the throttle body off the manifold I found that the there is a water journal surrounding the inner (engine) side of the throttle (pictured receiving the golden finger). Iíve read that e-series V8s have a heated intakeÖ is this what that literature is referring to? Is this to aid cold starts? Would I be well advised to just plug the two coolant lines entering this spacer and hence reduce the temperature of ingested air?
Secondly Iíd like to know what implications I would find should I remove the lantern hanging from the front of this spacer. Iíve photographed the one on my car currently and you can make out the part number (or bits of it just) if this helps. It has an electrical plug on it and also a vacuum / coolant?? (havenít had a good look, going from memory) line too. Is this for ignition advance? Hot start assistance? Would there any emission concerns with itís removal? The inside (air-passage) of the spacer plate has an ISC style hole in it large enough to comfortably house an index finger. This must disrupt air flow entering the upper inlet surely? Should I attempt to block this hole off too? Iíve taken some delectably low resolution pictures of the piece in question both as installed on my HO currently and of the one that came with the sprint manifold.
Thanks for your help
This is the upper before being cleaned and painted. You can see the peice between the throttle and the upper inlet with the bits and pieces attached to it.
Here is a view of the upper from underneath.
From the throttle side
This is the piece when removed
and finally this is a shot of the one that is currently instlled on my HO
