Boost VS EGTs

[AndrewKing]

HI All,



I'll be towing alot of sod here shortly... . the trailer weight will be a maximum of about 14K (lawn is big and I'll be making many trips so as not to exceed the GVW of the trailer)... ... I haven't gotten up the nerve to tap the manifold yet to install the EGT guage and I have heard that it is possible to exceed safe limits w/ a relatively stock truck..... My question is, can I use my boost guage as a rough indicator of how hot the EGTs are?..... Anybody have any rough idea what sustained running at 15 lbs boost is in terms of EGTs?... Are there any charts or formulas that can be used so I know how or hard or easy I need to be on the accelerator?... . I won't be speeding, since most of the roads

are windy 2 lane roads although there will be a stretch of highway I can run it up to 55 or so... . I usually tow 3500 lbs or so regualarly for the lawn care business I am in but I will be taking it easy with all that additional weight.



Thanks for any and all help



Andrew

When pulling I try to keep boost under 25 psi and EGT aren't a problem.

he's got a VE motor though. not sure about you, but i have never personally towed with one to know what they act like.



one thing i can offer is if you have run a long stint say, 15 seconds, with high boost you could back off for a few seconds and it should cool right back off. then get another gear or hopefully you are over the hill or grade.

Keep it turned up. Lugging will make high EGT in a hurry.
