ws721 Posted August 19, 2015 Share Posted August 19, 2015 Been running my EM9 kinda hard last few weeks. On my way down outa Maine last week I stopped for fuel, at an Irving which is all I pretty much use. Since then immedeitly after we lost @ 4-5 lbs of boost and the pryo doesn't heat up as much. Stop by the house to change fuel filters. Nothing changes. Truck runs fine but doesn't pull quite as good. What would cause the lose of boost? Still smokes the same. The weather up here is horrible with hot humid day & night. Any suggestions? Quote Remember if it's got a hood it's no good!

david wild Posted August 19, 2015 Share Posted August 19, 2015 Hot and Humid, Hmmmm maybe go for ride at night when cool and see if problem still persists, I remember when you 2 were in diapers. ??? now you can figure out where I'm from Quote Link to comment https://www.bigmacktrucks.com/topic/41419-e9-lost-boost/#findComment-300696 Share on other sites More sharing options...
ws721 Posted August 19, 2015 Author Share Posted August 19, 2015 No charge air leaks. Exhaust leaks yes. Wouldn't charge air leaks lead to high EGT? Quote Remember if it's got a hood it's no good!

rsb502 Posted August 20, 2015 Share Posted August 20, 2015 Charge air leaks could get you some high egt but only with plenty of fuel, exhaust leaks before the turbo will drop your boost and keep the egt down.

ws721 Posted August 20, 2015 Author Share Posted August 20, 2015 Hmm. I do have manifold leaks. Thanks for your input. This wintah were going to do some mayor rebuilding. Install my 18918B some 3.65 or 3.87 rears the Antrim turbo with the big spark plugs I bought. Guess I better do manifold work as well. I have a broken exhaust stud but its not leaking near it.

e9500v8 Posted August 26, 2015 Share Posted August 26, 2015 I can make 45 psi at 1600 rpm. This turbo makes good boost at low rpm !!Sent from my iPhone using Tapatalk Quote Link to comment https://www.bigmacktrucks.com/topic/41419-e9-lost-boost/#findComment-301587 Share on other sites More sharing options...
