  where i can i get a hold of him couldn;t find anything on ebay. thanks

  
  
  Try these guys:

  Lead wires:
  
  Libbybapa had bulk lead wire for very reasonable price, so if you need some contact him first befor buying it off of Egauges.

  OOOO, lookit!:
  
  
  
  Any one want a brand new, still in the bag, 0 - 30 PSI VDO boost gauge?  I might have one for sale now.

  I've bought a couple gauges from them.  They're OK in my book; fair price, fast shipping.  What more do you want?

• sounds good i'll give them a try.
  
  is there a difference between the $80 vision series and the $70 black cockpit one?
  
  just the way it lights up.

• The vision series is backlit and looks way cooler, the cockpit one is frontlit, so it looks more stock. I'm gonna have a cockpit EGT gauge and a vision boost gauge, kinda bothers me 'cause I would rather have both vision. :roll:
• #50 by vdubin_g60 on 13 Jun, 2008 23:56
• well i ordered the vision one.

• Well I just installed my Aircraft spruce thermocouple yesterday, man what a difference!! It'll actually pause between shifts as I speed up. Max temp in 5th gear going about 83MPH was 1160F. So after I get my turbo on I'll get to crank the fuel up a bit. :twisted:

• Here's a quick size comparisom.
  
  The VDO thermocouple is in the middle.
  
  The Spruce thermocouple is on the right.
  
  
  
  The philips screw driver on the left is there for a size reference.
  
  The VDO themocouple is slow.
  
  The Spruce thermocouple is stinky fast.

• Oh, By the way, The VDO probe uses a 1/4 NPT adaptor.  I hozed up and bought a Spruce probe with a 1/8" adaptor.  I called Aircraft spruce, and they said they can't just send me the adaptor.
  
  I have the probe mounted with a 1/8" to 1/4" brass adaptor on th 1/8" adaptor
  
  So i have another probe comming and will have a brand new probe, and a used 1/8" adaptor available if anyone needs one.
  
  In the 1.6TD, the Spruce thermocouple almost rises as fast as the boost gauge.  It stabilizes at 1450 F on hard acceleration.  Pritty high, but its rare that it sees that for more than 10 seconds at a wack.  And I have the piston cooling jets helping things out. I always wondered what the max EGT was when I was running the VDO probe, but it took so long to kind of stabilise, I was going over 90 MPH.

• Quick question about the EGT gauges. I have a VDO EGT gauge and the wiring from it has its own kind of plug to the gauge. Do all EGT gauges have the same kind of electrical connector and are all EGT gauges
  supplied with some kind of connector from the gauge to the pyrometer connection?
  Thanks, Josh

• Sorry to resurrect an old thread here...  Gonna do the VDO gauge / Spruce thermo.  Just want to confirm - I assume it's impossible / a bad idea to try to drill/tap the manifold on the car.  ...Or am I being paranoid here?
  
  Thanks!
• #56 by cyrus #1 on 16 Dec, 2008 23:54
• Personally, I would prefer to pull the manifold.  I hate trying do things like drill in really awkward places that don't have much room.  It will also be far easier to ensure that no chips get into the turbo.
  
  That being said, I've never done it in the car, so maybe it's not as bad as I think.  :lol:
• #57 by zukgod1 on 17 Dec, 2008 08:18
• I've done it both ways. I wouldn't really be all that concerned about getting metal in the manifold, grease the bit and most of the shavings will stick to the drill bit. Its a PITA doing it on the car though. More of a pain than removing the turbo and manifold? Not sure.
  
  Your call.
• #58 by jtanguay on 17 Dec, 2008 08:26
• i wonder if you somehow hooked up positive pressure going to the turbo as you drilled it so any shavings/bits would be pushed outward...  might be more trouble than its worth though?  how about just running the car with an open hole and giving it a good few revs?  :twisted: then install the probe and enjoy?  
• #59 by arb on 17 Dec, 2008 09:03
• I would pull in and drill on a drill press. When I tried to drill mine free hand, at the end of the cutting the bit snags causing the drill to tilt ever so slightly and it cracked the manifold. The second drill was on a press and was perfect. In the car, I think you would be more contrained if you don't have a drill press to use. Towards the end of this page you'll see my EGT drill and taping.
