IAT relocation: Any no-weld options?
I'm adding meth and an A&A blower and need to do the IAT breakout and relocation, and from what I'm seeing everybody is using welded bungs.
Well, my charge tube has a beautiful black powdercoating that I'd just hate to have to re-do, plus I have no experience in aluminum welding (and not sure where to get it done at), so I'm wondering if there are any rubber-grommet style, or 2-piece screw-on (kinda like the meth injection kit) for IAT relocation?

A welded bung heat soaks the iat sensor giving it a false reading anyways...
Do an ls1 iat with the rubber gromment from Gm... Air tight seal and no heat soak due to the material
Just bought the sensor for 18 and the gromment for 2.50

Hmm, this isn't a bad solution, the plastic has a bit more bite for the pipe thread on the IAT... has anybody done this? I'd like to see pics!

For the iat1 just have the tuner pull a ls1 fbody/vette file and copy over the iat table (have to change the axis too but that's easy)
As far as the intake... I've done it before but no pics.. Look behind the throttle body on the passenger side and there's a great spot

Cool, that sounds like the way to go, then.
I ordered an IAT MAF breakout kit from Dedicated Motorsports, thanks to DSteck. Great customer service, by the way, about 5 minutes after my order, I got a call asking if I needed a weld-in bung. I told him nah, I'll drill and tap the intake manifold. Comes with the screw-in IAT sensor that should work, M14x1.5 I believe. Also comes with a 3-bar MAP sensor - I didn't realize MAP was on the same harness as the MAF and IAT, but I guess it makes sense. What happens to the old MAP sensor connector?
I'd still like to see a pic of one in action, so I know exactly where I'm putting my sensor. I'm probably overthinking it, though.

That map in the pic works as a Baro sensor, just leave it vented in the engine bay....
Leave the stock map on the intake manifold (middle driverside) or replace the factory sensor with an ls9 to read boost and then use the factory lt1 sensor with Dstecks kit...

So this breakout kit comes with a 3-bar map sensor for baro... But I can use that in my manifold for boost, and then use my stock lt1 sensor in the breakout kit for baro, vented?

I can't find any place on the manifold where I can insert it and be sure that it won't interfere with the throttle blade operation.
I ordered an LS1 IAT sensor and a couple of grommets and can drill a hole in the charge tube if I haven't found an appropriate manifold location.

Edit: Just saw your second post with the thread size. I believe this is the LS9 one? A quick google search says I'm on the right track, but I'd like confirmation.
I also have an LS1 IAT sensor, should I need to go the grommet way:
but I worry if I drill the hole too big, the grommet and sensor will pop out under boost.
