LML Mishimoto intercooler

[Goss]

Has anyone installed one? Does it lower egt's? Any other noticeable differences? I have a 16 68mm turbo, built trans, pipes, egr delete, exhaust tunes etc etc. Wondering if this will lower the egts and any other noticeable items.

What all are you trying to accomplish? Are your egts getting out of hand? When is this occuring?

People keep saying there products have gone down hill, quality and what not

My egts are running 900s cruising unloaded 75mph

 

[Yngdmax92]

I guess I don't understand your concern. Plenty of people have installed larger turbos on these trucks without a problem with egts just cruising. Have you tried different tunes? Tuner ? Or possibly ask for a tune adjustment.


Who's 68mm turbo you have? What are the specs of it?

An intercooler will do virtually nothing for EGTs under light load/low boost conditions.

I would be looking at the tune.

I see 900-1000°F cruising down the highway at 75+ MPH in my truck, measured at the passenger manifold. Depending on lift, tire size, weight, etc., 900° doesn't sound unreasonable at high speed.
Like JoshH said, an intercooler won't help unloaded EGTs at all.

but thats with your fixed vane larger charger aint it? the last couple 68 danville stg2r's i was in would see 700-800egt max in 6th gear at 1700rpm. These were LMM's though.

Yes, a fixed S371 on a motor with a big cam and lowered compression.


And you are right, it is all in the tune. Add some timing, more heat goes into the coolant and less to the exhaust. Remove timing, more EGT less ECT. For my build, running a bit lower timing at cruise brings the best mileage. On a stock motor, I run a degree or so more timing at cruise. I want to say I am at 6-7° on my truck, and 7-8° on the Suburban (stock motor).

Thats interesting Dave. was the lower timing due to the SAC injectors or did you have it set this way prior to the SAC ones too? honestly just curious is all

I never got enough miles on the first set of VCO injectors to fully adjust the tune to my liking, so that adjustment was with the SACs. They could be the reason it likes a little less timing, never thought about it.

My tuner wants diagnostics, sending them hoping that fixes it
