OK - not to kick a dead horse, but I have a new scenario and would like some input from the gurus. I hope that someone has some real world experience with this setup. I have my egt probe post turbo, but I also have the Bank's power elbow (NO EBPV).
Could this allow for a truer read on the post turbo egt's?
Has anyone compared pre and post temps with the EBPV deleted?
FYI - I was running hard to check out the new gauges and the highest I got was about 750 with WOT in 95 Texas heat and stayed around 680 at 1900-2000 rpm cruise on. (Also, 19.8 psi boost max)
Great post JT,
Glad someone finally got some firm numbers. Glad I took the time for the pre turbo fit. Good thing your young enough to watch all those gauges and still see where your going.
Left you some points for your work.
SSGG, I don't thing that having the EBPV deleted would change much in the way of EGT numbers. The EBPV isn't all that much of a restriction when it's open, so I don't think they would change much, if at all. To my knowledge, no one here who has the EBPV deleted also has both probes. But, if you're only hitting about 750 post turbo, I'd say you're well within the safe range.
zx, thanks! I know it's something that's always debated, and I was curious myself, so I found out. Appreciate the rep points too!

Yes, I have had it about as long as the gauges. I had a couple of tuners, felt the surge, and wanted to get rid of it. I figured I would get everything right for jody to do his magic. I do have plans for fuel system mods, too.
Fellas just bought a new probe and wiring and i tapped my driver's side manifold for the pyro. Seems to have been too many horror stories from post turbo probes, and with injectors comming in the future, I wanted to be very safe.
I will say it is amazing how much different the temps are! My question is what is now the safe cool down temp for the turbo before I shut 'er down? I used to let it fall a little below 400*, and oftentimes had to wait some time before turning the truck off. With the new location, I get low egt readings much sooner than before and find myself not having to wait to turn off, and wonder if the turbo is still too hot when the pre turbo pyro reads 400* or less? So what do you fellas think? I left the probe and wiring for the downpipe, but only have the one guage so I don't compare temps.
Thanks as always!!

i let mine cool to 400 pre-turbo, and at an idle when the turbo is just spinning over at idle, it barely uses the heat. i would say 350 post turbo is equivalent to 400 pre turbo? ideas? tonight i kicked my chip to hi-idle while i was closing the shop doors, it brought temps down from 500 to 400 very fast, compared to idle.

Ideas....heck, I know this one for sure. Idle temp difference is in the neighborhood of 25-50 degrees, but closer to 50 degrees. The flash point of oil is somewhere around 450-470*, so I'd say the safe range for cool down is 400* pre-turbo. However, I typically take extra care and let it get down to around 350* pre-turbo, well I actually watch my post turbo gauge at shut down and shut it off at 300*. Remember that heat soak in the turbo bearings and surrounding housing may cause temps to rise once the cooling oil flow stops. And I think it shows. After 3 years of hard driving that I've put on my turbo (it's got 155K on the stock turbo now), it still spools down freely after I shut off the truck.

A late addition on drilling the manifold. I was talking to a local shop and asked the question about drilling into the manifold. They told me that they drill into the manifold with the engine running. Wear a face shield and let the shavings blow out. Keep it running while the threads are tapped. I have NOT tried this myself. Any thoughts?

this was how I did mine with the added step of not plugging it in the night before so my EBPV was activated. there was an insane amount of pressure comeing out of the hole while I was tapping it so I am sure nothing stayed in there.
