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

High boost isn't really a good indicator of high EGT's. If anything a fair amount of boost may keep egt's lower. A large amount of fuel being dumped into the cylinder without the air to burn it is what makes for high egt's. Hot footing it with the rpm's low and the boost pressure in the mud will push the egt's up quickly.
Keeping your rpm's up above 2k will keep enough air flowing thru the motor to keep things cool, so as long as you don't jug the motor you should be fine. Though if I were you I would get a thermocouple installed.

Tap the manifold already.

It's a 20 minute job if you take your coffee cup with you when you do it.

I just did mine and was nervous, but it worked like a charm.

If you want to be alittle lazy then have someone weld a bung into the exhaust just after the cast iron elbow and put your pyro there. The temps be about 400 degrees cooler when pulling hard but you can still use it cooling down prior to shutoff.
I have both installed and when I'm running @ 1200 pre-turbo the post turbo is about 800, during cool down they both 300 about the same time.

Thanks guys, I just downloaded the location to tap the manifold from PIers Dieslel and I I am psyching myself up to do the job....I guess I really don't want to screw anything up.....well at least its supposend to be nice tomorrow!

Do it with the motor running, blows the chips out.
