Finally installed my juice/attitude...Im curious what is the max safe boost, and egt??? Cruising at the stock setting, when I mash on the peddle, my boost almost always goes over 30 psi!!! I dont know if thats a bad thing or not...any info would help.....thanx

 

were is the exhaust probe? manifod or turbo exhaust pipe? and what are the temps? i have a ? for ya s2gots = stugots?

 

exhaust probe will be at manifold....or can I install at exhaust pipe??? what if any is the difference..other than different temp readings?? Im taking it in this weekend to a shop to remove manifold and install....unless post turbo will work??!!

yes, stugots.!!!!!! s2gots is whats on my plates, and it kinda stuck on to me as a nickname with my friends!!!LOL

 

I see 32 to 35 pounds with the hammer down and around 1200 EGT at 3300 RPM top gear with the hammer down but it seems to have maxed out at that number.
I have a Predator on the 65 setting which is generally agreed much more than 65. Check my gallery for the dyno sheet on 100 HP program.

 

s2gots, the following is from Gale Banks (Turbo) engineering:

What is the best location for the exhaust gas temperature probe on a turbo-diesel? This question is tougher to answer than you might think. There are two ways to measure exhaust gas temperature on a diesel engine: before the turbo (turbine inlet temperature); and after the turbo (turbine outlet temperature). When reasonably convenient, we recommend measuring the turbine inlet temperature, because this is the hottest—and most meaningful—temperature when evaluating the engine's performance. But when there's not a convenient place to put a probe in the turbine inlet side of the exhaust, the alternative is to mount the probe after the turbocharger, measuring the turbine outlet temperature. But this also presents a problem. The outlet of the turbo on the Duramax engine, for example, is shaped awkwardly, and the factory turbine outlet pipe is a very non-concentric shape to accommodate the outlet, so once again, there is not a good place to install a probe until about two feet after the outlet of the turbo. By going that far downstream, the integrity of the measurement is sacrificed.
Perhaps the best recommendation is to drill and tap a hole in one of the exhaust manifolds, and install a threaded pyrometer probe in there. Just be VERY CAREFUL about not getting any metal chips in the manifold, which would cause damage to the turbocharger. About the only way to be sure of this is to pull the manifold off of the vehicle to do the drilling and tapping.

Can failure of the exhaust gas temperature probe damage the turbocharger?
This is a highly debated issue. Some of the sentiments that surround this question date back quite far. Before diesel engines became widely popular in pickup trucks, the main use for diesels was in the long-haul trucking industry. Years ago, when truckers began to use pyrometers on their engines, the most logical place to position the probe was in the exhaust manifold ahead of the turbocharger, because this was the hottest portion of the exhaust stream. But the earliest probes that were used had exposed junctions, and the weakness of this design would sometimes fatigue and fail under the high heat conditions. A failed probe would inevitably cause expensive damage to the turbocharger. The solution to this problem was to move the thermocouple downstream of the turbocharger, thus avoiding the potential damage to the spinning turbine wheel. Knowing that the temperature would be lower in that location, it was expected that the operator would compensate for the difference by an appropriate amount.

Today, the thermocouple probes that are used are commonly sheathed in a stainless steel shell that is impervious to the type of failure that an exposed junction thermocouple might experience. This makes it safe to install upstream of the turbocharger. At Banks, we typically prefer to mount the thermocouple upstream of the turbo, but this is not always convenient. In the case of the Ford Power Stroke, we opted to provide a bung in the turbine outlet pipe rather than having the customer go through the difficulty of drilling and installing a probe in a location that is hard to access. Our testing shows that the maximum allowable turbine inlet temperature of 1350 degrees is equivalent to 1050 degrees on the turbine outlet side, so that is our recommended maximum temperature when measuring in that location. The temperature differential may be broader at lower temperature ranges, but the temp that we are most concerned about is at full power.

 

that was a good amont of info from banks...thanks for that! So, Ill set my egt warning at 1300, just to be safe, and boost warning at 30ish...thanx for the help guys.
