Cummins 12 valve 1400° OUCH help!
 

I need some help, I just put a new stock turbo on my truck, and I noticed my egts have been god awfull high, they were fine with the old turbo. But I was doing a burnout today and I looked at the guage and it was pegged to 1400. It stayed ther for maybe 10 seconds, then I let off the trottle and it died. I couldnt get it to turn over. It sounded like it was semi-seized up, but I kept cranking the motor over, as it would spin then stop tgen spin again., I did this for 30 minutes at least. and as it was cranking over I could hardly touch the throttle and it would stop cranking all at once, so I had my buddy pull me back to the house, while I was being pulled I thought I would try to crank it one more time , (its auto trans so no pop start) and it fired up and runs fine. Im confused, and need ideas as to why it did this and why my egts are so high.

maybe the wastegate was open or a boot is leaking........................what kinna boost pressure was you showing at the time?

i was around 20-25psi which is weird because my old stock turbo i could hit 35 no problem, i cant even see 30 psi on this one.

somthing is wrong with that charger

could a small leak or the wastegate not adjusted right be the problem?

if your not getting the same amount of air in the motor then yes egts will be higher

does the truck have a TC lock up switch?

no, i have just the overdrive that keeps it from shifting into fourth gear.
i have a triple disk converter idk if that has anything to do with it.??
