Do you have any pictures of the pyro sensor install? The one I have been looking at for my 12H-T is really long like six inches or so. Yours look a lot shorter or maybe it is inserted into the elbow with its full lenght?

Mine is the one that came with the autometer gage. I had to use a reducing bushing in the elbow, thus the probe is not deep in the elbow, but it has been showing good temperature. There is a thread about my pyromter install and there should be a picture there. Let me search for it.

OK, thank you for that. Think I will do a similar instalment on mine. The 12H-T also has a drop bend like this so it should be quite nice.
And one more thing, that voltage regulator seems fairly close to the hot exhaust elbow. Get a shield or move it. It has got coils in it with laquer on the thin cables. Has a tendency to get coocked easily. A steel plate would do as a shield.

Finally i've removed the silencer, so now i'm straight pipe. It now has some sound, before it was real quiet.

you gained 26 hp, that is pretty good...

Yep 50% gain.
Any advice on where the best place is for the EGTemp Gauge? I have mine at the elbow leading to the down pipe and have tuned my fuel so I reach 1050degF under flat-out full load up a hill with a 25mph head wind plus 1000lbs of stuff,people, etc. Am I really at the "1000deg" safe mark or is something happening in the turbo or elsewhere that I might regret?
Also - my turbo has a pushrod actuator at the wastegate which is threaded for adjustment. Stock from Denco the Actuator is set to hold 7.5PSI, I would like to move closer to 10PSI... I have no Boost Gauge yet...but will shortening this pushrod increase boost, or will it simply delay the wastegate opening?

THAT is what increases the boost, the simple delay in wastegate opening...
Boost
Thanks Crushers - This justifies the need for a boost gauge...
Any thoughts on the EGT probe location question - how hot am i really getting at the turbo.
A buddy of mine has a Top Mount Intercooler I am considering installing, not sure what size or from what vehicle it came - any thoughts on the efficacy of an IC on a 'low boost' set up such as mine?

a pyro is just a suggestion, if preturbo then 1000F post turbo is 1200F and this is just a suggestion as well. as Bruce pointed out, how many people have actually seen any damage from over heating?
intercooler, something is better than nothing but sometimes nothing is needed.
intercooler, something is better than nothing but sometimes nothing is needed.
So as I understand it I can concievably increase my fuel till my (post turbo) Pyro reads 1200, and I should be running 1000 pre turbo, which shouldn't cause too much drama with the head etc.
Intercooler in Las Vegas- we get summer temps of 120deg F and our base elevation is 2200ft, I think I will go for it. Besides a hood scoop on a 60 series might loook rather cool.
One last question- which will increase boost: shortening or lengthening the waste gate actuator arm?
Thanks Crushers-I appreciate your expeience!
No.
The temperature drop across the turbo is never constant, figures quoted such as 200F are fudge factors with no basis other than someones auntie once measured it on a completely different engine running a different turbo, different boost and at one operating point which has long since been forgotten.
The actual temperature drop depends on your EGT's, pressure drop across the turbo and turbo efficiency. It can vary from 0-300C.
If you want to know, then shift the probe to the exhaust manifold. Otherwise you're just guessing.

post ho
well yes and no, Dougal does have a point. it was a test done on both a PZ and a 2LTE, both showed roughly a 200F drop through the turbo but each situation is different.
BUT
1000F is a very safe temp restriction so even if the fudge factor was 300F then you would still be within safe parameters.
for the ambient air temps you are running in a top mount would be good. the hood scoop design is important for slow speeds. if the face is bigger than the dump the air flow will be forced down through the intercooler even at slow speeds...

Roger that! Where's the ideal point on the Exhaust Manifold to stick the probe?
Right now the turbo mounts midway between the middle two exhaust ports.
As for the efficiency of this turbo, not sure how to measure that or if it is something of a standard for its size and capacity.
BTW- thanks for the info,as you might have guessed this is new territory for me.
The best point is where the ports merge, usually at the turbo inlet. Alternatively if you know one port runs hotter than the rest, monitor that one.
Unfortunately you can't funnel air to accelerate airflow as wayne thinks.
The air velocity you can reach is limited to your forward speed unless you've got a fan or vortex sucking air out the other end.
