IDI Engine / Re: I am starting a 1.6TD build version 2, hoping for more than 40,000 miles :D

OK,  If it doesn't rain too much on Sunday, I will pop the hood and torque on a couple of those adjustment thing-a-mah-jiggies. 

If I bump the boost up, I might not need to shift in the middle of the grade, doing that generally puts me in a no boost zone and in third.  Not great performance at that point.

Gee, I was running up one of the longer, more sustained hills in town and had it in second rather than third.  I felt it bump a couple of times and noticed the boost was at 10 psi.  Maybe I need to crank it up a bit.  I do have ARP head bolts on it. 

What do you think?  Take it up to 12 or 15 before the wastegate opens?

Right, the big thermoswitch in the front radiator waterneck is inline with the power to the AC.
 Shuts it off if the coolant temp is too high.
Glad to hear you still have a VW diesel to work on.

Great story.
 Part of VW turbo diesel history.
I've popped my 1.7 VNT-15 up to 35 PSI (guessing because the gauge goes to 30) a couple times. Not sustained.
Before I had a controller.
It didn't blow up. But sounds like a lot for one of these.

Yes, with only 18 posts, your time on the board means little to nada.  Get some conversations going, and your status will change.

Rambling through older posts I found this one and discovered in it that the unused two wire sensor on my engine might be an A/C shutoff sensor. How the heck I've never noticed that in the Bentley diagrams I don't know, but I'm pretty sure I'm going to rewire my compressor a bit to use it. Because...now that I know it will bug me.

Also just noticed though I registered here 20 years ago I'm still a "newbie".

steve ran your block, head, and intake in 2023 when i was there. it was a bad week for LSR, there had been a lot of rain before the event. The start of the event was delayed a few days and then when they did start doing runs they only opened one short track, so it took forever to get a run in. No new record was set that year because of limited runs and the engine was running very hot and performing poorly intake temps that were the same as the ambient air and 35psi of boost. It seemed like any adjustment made on the pump didn't change anything it was supposed to and when steve got back from bonneville he found parts from inside the pump stuck in the "out" bolt screen. so, something was wrong with the pump. He had a spare pump with him but we didn't know what was wrong at the time and with the poor track condition and limited time/runs everyone decided to head home a day or two early.

Welcome back.
The bosch rotarys just don't push out the fuel like the inline P-pumps
The timing curve isn't as adjustable either.
