That's awesome Quick!
Depending on where the sensor is in the crossover, the reading could be 100-200 cooler than exhaust coming out of the heads. What's important is making sure the aluminum pistons don't start getting soft.The dang egt gauge on startup is at 150. I have tocallglowshiftto see if there is a way to zero the needle. And the pickup is in the crossover pipe.
This made me look up what normal temps are for an E4OD and it seems that 200F is just fine. Reading around other forums 230 seems to be the max safe limit, but lets face it, you don't want to live there.Too late. When I finished up the turbo and installed the gauges I took it out and pulled the trailer with arond 5-6 tons of stone to see how it went. It pulls great, but the trans temp got up to around 200-205 degrees and that made me nervous. So I went and put another cooler in line with the factory one. I was reading that the transcommand woulds keep the trans from slipping. And I'm sure that was the reason for the spike in temps. So I put the transcommand on and now it holds the gear longer like before. But what I have noticed is the temps rarely go over 170 degrees now. And that is with pulling a full load. I don't think the additional cooler would have brought the temp down that much.
