got some gauges finally just wondering where the best places for the sending units are? i got trans temp, boost and egt. i know for the egt the best place is the exhaust manifold but some have said they put it after the turbo in the down pipeso the dont have to worry about getting shavings in the turbo. boost i have no idea and trans i think in the oil pan.

advice would be appreciated

 

I put my tranny sensor in the test port. Works great there and is easy. I used the clamp on probe for the pyro in the down pipe under the manifold. Super easy, seems to work well. Boost went in the line that goes to some gizmo. Can't remember the instuctions exactly. It is on top of the engine toward the firewall.

Should find them to be pretty helpful.

Advice on the pyro - just be careful and follow installation instructions. Then you don't have to worry about shavings. Pay attention to methods for reducing the size of shavings and removing larger ones. Even if small shavings are left behind, at idle, they will blow harmlessly through the turbine. It isn't as big a problem as you think.

HOWEVER - if you choose to put it post-turbo, then be aware that post-turbo is MOST innaccurate when you need it most - high boost/high load situations.

Read the linked thread for some great data that jtharvey gathered concerning pre-turbo vs. post-turbo pyrometer probe installation.

 

I was shaking with fear when drilling the exhaust manifold, but as mentioned above it is not as bad as you think. Just take your time, and start with a small bit and you will have no problem. One thing, don't forget to cover your eyes as the shavings will fall directly on your face.

 

read this thread if you are worried about drilling your manifold. i think this is the best way to install your pyro but i havent heard of any problems with a clamp on thermocouple either i just feel the drill and tap method will seal better

On using eye protection - YES! - the drill cuttings go everywhere and are annoying enough just on skin. They won't be annoying in your eyes, they'll be damaging.

I used grease on the drill bit tip to try to control where the shavings ended up - mixed results. Most of them ended up stuck to my arms, shirt, and face. Oh, and many stuck to the safety glasses, too.

Then I used a magnet inside the hole after tapping (didn't get much), and a shop vac with a 1-inch nozzle. After that, I started the engine and let it idle, then set my chip to fast idle for a few minutes. No problems.

On the above-referenced thread, it mentions that Banks says to put the probe post-turbo 'in case you push such high EGT that you shatter the probe and push it through the turbine.'

That is a valid point, sort of - or, it used to be, anyway.

Modern probes aren't really prone to failure like the older ones were. Metalurgy has come a long way, and they are pretty damn durable. Also, if you're pushing THAT kind of EGT, you're not watching closely enough - and if you're going THAT high, a post-turbo probe will lie to you anyway. You'll be in trouble and not even know it.

Be sure you read jtharvey's findings in that thread I linked earlier.

 

I agree, the probe breaking off is definitely not a concern or valid reasoning for putting it post turbo. The thermocouples are made of Inconel, the melting point of which is about 2500 degrees Fahrenheit. At those temps, your engine and turbo would be melted or damaged beyond recognition... and a broken thermocouple is the least of your worries.

 

i thought they were made of inconel also but others on here have said they were just cased in stainless steel. does anyone know for sure what they are made of?

 

yes, they are made of inconel. the only possible situation i could think of with breaking the tip off would be that it got so hot, that the piston started to melt, and a chunk of aluminum went out of the head and in the manifold, where it hits the thermocouple and breaks it off, sending it through the turbo. but if that happens, a new thermocouple and turbine shaft is the LEAST of your problems.

 

Put your EGT probe in PRE-TURBO, for all of the above reasons....

Since nobody touched on it, your boost line should come out of the intake manifold, since you would have to drill and tap to put the compression fitting in anyway, I think it's a great time to do the Air intake heater delete mod as well. Just unscrew the electrical connections to the AIH, unscrew the AIH, and screw in the boost fitting that comes with your gauge. Your boost line now will read the REAL boost pressure instead of "T-ing" into the MAP line.
If I missed anything someone will assist my description....

Your tranny sender goes in the test port, it's drivers side just forward of a big electrical/mechanical connection point on the tranny. It's just above the pan flange.

Hope this helps, when in doubt consult your directions....
