They had a thread on here about testing those various EGT set-ups in real world conditions. The spruce kicked butts.Fatter exit pipes on Klaus will benefit him more than anything.Lower EGT, lower coolant temps, lower oil temps, higher power output.They looked like 2" ID or less.I'd put that before intercoolers and air/water systems in terms of priority.
above is the CE2-1. Loved for cool down as it goes down to 100 degrees.That is the micro-1000 from aircraft spruce and here is the part#10-01478This thread covers them wellhttp://www.vwdiesel.net/forum/index.php?topic=25202.0
I was looking at what Techtonics Tuning has for the 1.6TD (2.25" DP and exhaust system), but very pricey! Almost a thousand bucks once its all said and done.Maybe you know of a more local place that can do it cheaper?
Moving right along !Nice Work - especially on getting the DownPipe off.That engine was in need of this, if just to get the water jackets and passages cleaned out right again.If its at all possible - try to take the block to a shop that has thermal cleaning. Its way better on the water jackets than conventional, and they need full attention in there. Thermal will make those jackets look new on the inside.Even if shop of choice doesn't have it - you could just have it thermaled at one place then take it on over to your selected machinist.What is the part number on your cylinder head ?End with 373 T ?
