Question Which Westach probe with VDO EGT Gauge

Recently I purchased a VDO EGT gauge (310-151), but decided not to get the VDO sender because many people have claimed it's slow to respond.

Instead I'm looking into buying a sender from another manufacturer and using it with the VDO gauge. Obviously Westach is a popular choice, and they are reasonably priced. The only other option I could find was from TRE (http://www.teamrip.com/pricing.html scroll down). They offer a "ultra fast responding probe" for $38.00 which they claim will work perfectly well with an VDO gauge.

The problem gets to be lead length. The type K thermocouple wire has an resistance of 0.625 ohms/ft, which means that the lead length directly effects the output voltage of the sender, and the corresponding reading on the gauge. The TRE has an 18" lead and Westach will make a probe with any length the customer wants.

My question is, what is the lead length of the VDO probe? A search turns up people using Westach probes with 1' to 4' leads. Obviously many of these leads are causing an inaccurate reading. Does anybody have a VDO EGT sender, or know the length of K type lead wire VDO uses? I've emailed VDO, but doubt I will get a reply.

On another topic, some people have posted that an open tipped probe could break and be ingested by the turbo. Both TRE and Westach say they have never heard of this being a problem. I'm probably going to go with an open tipped probe because of the much better response time (no cover for the heat to transfer through).

Hopefully we can determine exactly which EGT probe will work with the VDO gauges so that more people can use this combination.

Anybody? Did the other people who are running VDO gauges with Westach senders not look into making sure the gauge would work with the sender?
