One downside to the reliability of TDIs is that I don't have cause to look inside. Now that we are FINALLY getting around to building a fairly warm 1.9, I pulled the head to de-coke (yucckk!) and do a little cleaning up. The intake ports are the strangest thing I have ever seen. Looks like VW was trying to get the intake air to swirl at the valve?
Anyone had any time to put one of these things on a flow bench and see what can be gained? Sorry to be posting this late at night for our Eastern members. It is tempting to hog the corner off of the directional "dam", but intuitively, I think there must be some pretty good reason to bias the flow so hard to one side.
(on edit) Another question: what revs are those valve springs good for? I have that much on Honda roto-tiller engines!@!
