Turbo for a hot 6nz

The lower boost could also be from timing too far, right? If it's too far advanced another tune backing it off a few deg could gain the boost back, drop cyl temps, lowering water temps. That is if no boost leaks. Just speculating

 

Check your coolant pressure, then you will know. You may have to run down road with a gauge on mirror bracket

 

absolutely will not. He has other issues. and why does op think that 180 degree thermostats will help with this setup. Not gonna help with tuning issue. even with for example 190 degree t-stat, they gonna be open full flow. 4 core rad should be sufficient

 

A buddy of mine installed one on his 3406E. His exhaust temps came way down. Not sure if he has a standard 4 core or not. But they make a 4 core with dimples rated up to 1000 hp

 

Just throwing this out there- I had an 05 379 with an Acert that had been 6nz,d. ECM, head, low comp industrial pistons, single turbo, blah, blah, blah. Supposed to have been set around 600hp. It kept wanting to heat and fast even with new hi perf radiator and cac. Kept me scared to death of frying it. But I also started to notice fan wasn't always kicking on at the right temp. Got to checking with temp gun and reading ecm events and decided gauge must be off. Replaced both temp senders and gauge and it seemed to help for a few days then same nail biting xx. So I bought a Scangauge D. I found it handy for lots of functions but mainly water temp. I could see what the ecm was reading which pretty well coincided with my ir temp gun checks. Just gave up on the Peterbilt dash gauge and watched the readout.

 

So these other guys that are running hot cats are theirs tuned by the guy that tuned yours?
