flat range 500-650*F. Uphill 800 to 900*F the most. Normal shifting barely any to little smoke. Getting on it, itll lay some clouds.

 

the rite injector lift with the rite piston bowl with rite timing will bring egt's down. considerin a 145 angle ingle injector above a 145 bowl piston thinkin about it does more good than harm. im in need of gauges... i dont wanna hear it ive not run these so i dint know how hot ill be but im askin timing or no timing for now

 

what injectors are you running? 370's or a different one?

 

its pretty simple folks, more timing is less egt, at the cost of higher cylinder pressure. on any other engine you would get away with alot more timing at higher rpms because cylinder pressure decreases as rpms increase. but on these motors you can only run as much as you can get away with at lower rpms, which is why i really want something with variable timing like a duramax because you can idle smooth at negative timing numbers, run all the way up in the 30s at high rpms, and even run low timing at the line for the extra heat to spool the turbo at the drag strip, not that im bashing the ole 12v cummins at all but im trying to give an example of what situations call for what timing and how these trucks leave you with one timing for all situations. so just keep in mind its always a trade off, these trucks have a very short powerband and live at low rpms so a ton of timing isnt a great idea since your stuck with it at all rpms. the reason old diesels clatter alot more is because of timing, modern diesels smoothed out alot just from running next to no timing at low rpms. all that being said, ill probably set mine at 14 degrees when i do the job, just because i want better feul economy but i know that is alot of timing for idle, even 12 degrees is alot of timing for idle imo.
