Can,t read the numbers on my turbo what do I need to get my egts down towing 8000lbs yesterday temperature post turbo 1100 degrees

cheap way to lower your egts would be changing your exhaust housing and air filter, then again there are other ways.
what year/model is your truck? That'll be a start...

There are a lot of things you can do. You can start with a 4" exhaust and a better flowing air intake system (BHAF). Whats the year of your truck and is it stock?

1990 w250 stock except for timing bump in fiurth gear this thing just dtarts to pull good at 50mph

I think a free flowing exhaust and a BHAF will help. HTT turbo & Gillett diesel also have up grades for our turbos. Don't know how much your willing to spend.

60mm turbo upgrade, 4" turbo back exhaust, BHAF intake.

You should look into an intercooler , that will make the biggest difference.

a 90 will have a tiny 50mm inducer turbo, a 60mm would be a good upgrade

Also, move the thermocouple into the manifold. You cant always rely on the "Add 300deg theory".

How many RPMs are you turning? You arent shifting too soon, are you? Basically run it to near the governor before shifting- you want to be in the 1800-2000rpm range when you start out in your next gear. 50mph in 4th towing is a great RPM, if your EGTs stay in check. RPMs are your friend, use them.

How far was your timing bumped? What were EGTs like before the timing bump? For towing, you want to stay on the lower side than for a toy. I'd start at stock and go no farther than 1.7mm.

Wouldn't waste my money on anything less than a super 40.

Finally drove my truck with a regular 6 blade 60/65/16 hx-40 and it is sweet!! I had the GDS 8 blade 60/60/16 hx-35 prior, and it doesn't even compare. Spool is the same, but if you think the GDS 60 whines, the 40 whines 2x that! And so far haven't seen over 1200deg, haven't towed yet but am looking forward to it!

Never had pyro before timing bump its just a little beyond stock.Called gillett deisel today they say need 16mm exhaust housing and not an air to air. Don,t have a lot of bucks to spend right now so got to get by. The pyro probe is from a transport and is to long to fit into the manifold have the hole all drilled and taped it bottoms out on the bottom of the manifold

They don't know what they are talking about.

I'd have to agree- one should never say no to air-air. Is it absolutely needed? Maybe, maybe not. But it's impossible to cool it too much.

Hauled the trailer tonight its about 75 degrees stood right in it and the pyro stayed down to around 1000 traveled at 70mph most of the time

dieseldawg604

correct me if im wrong but a smaller turbine housing will increase egts!!
wouldnt it??

avengerdude27

i have a nice used 12cm with the flange and elbow id sell you if you want to change housings

peobryant

Yes it will.
