Here's a video of the turbo shaft play.

I think it will do just fine. Opinions? -

its a bit playful, but really spins nicely, looks good to go imo

It wiggles, but has absolutely no blade-to-housing contact, and spins freely. No in-and-out movement at all along the axis of the shaft.

Just for a heads up...I just placed this EGT/gauge into my 1.6 NA/TD car.
EXTREMELY fast response.

That's the same gauge I was planning on buying... Any way to make a video of temps climbing while you're at WOT? -

Do they make EGT probes smaller than 1/8 NPT? Less mass = faster response. Something like 10- 32 or 10- 24 would have much less mass. Can you get probes in those sizes?
Many years agoI worked in a coal research establishment and one of my tasks was making up platinum/platinum-rhodium thermocouples up from fine wire, and ceramic sheathing. The fine wire would take the heat, as it needed oxy acetalene to fuse the wires togeather, but I'm not sure if you could callibrate the basic gauge meaningfully... -

Wish I could get one of these 3" gauges:
perhaps replace my gasser tach (which will no longer work with the diesel). -

When you say it has extremely fast response, what testing have you done? Data points please.
Testing? Seriously....I'm not an engineer. I just build stuff in my garage. 16vT, 20vT, TDI, g60, TD currently a VR swap. Anyway...
What I mean by fast response is when I turn the key on...it's ambient temp(correct for cold engine), crank it up and response is fast. Rev it up and the numbers rise and fall FAST. Not 23 seconds...instantly. WOT pull will yield 1500 degrees and let off will pull it back to 700 in a second. So. 1500 to 700 in a second is pretty responsive if you ask me.
And the probe you show and say you like is identical to the one that came with my gauge.

Yeah...I can make that happen. Tomorrow on the way home church I will make a video. -

Wow, that's responsive. And gorgeous GTI, I hope my Fox TD sounds half that good.
1500F seems high, no?

Updates in the vortex thread. Set my IP lift timing.
EDIT: This is a METRIC dial indicator, and the black tabs are set at the factory max/min values.
I err'd on the advanced side. Thoughts? -

It should be between .037 and .043 ... I have no clue if you are way above or below. I would go with somewhere in the normal range.

Guessing that is at about 1.03mm? Should be fine! You can tweak it a bit from there to find the happiest mileage, etc.
