Superdog Posted June 2, 2015 Share Posted June 2, 2015 it should do better than that. whens the last time you cleaned your intercooler filter. Quote Link to comment https://www.bigmacktrucks.com/topic/40285-boost-pressure-300/#findComment-292028 Share on other sites More sharing options...
Lmackattack Posted June 2, 2015 Share Posted June 2, 2015 That's way low... My 285 will pull almost 30psi on a good pull...Some Simple things to check first would be looking for a boost leaks,filter clogged, charge cooler clogged, turbo fin damage.My 285 had low boost and high egt temps. I found that my turbo was bad. A crack in the turbos exhaust housing allowed it to melt the internal passage near the blades of the turbo. It was melted so bad that center section allowed The exhaust to bypass the exhaust fins thuss it was not building boost like it should have been.

b61mack Posted June 3, 2015 Author Share Posted June 3, 2015 I don't have a intercooler filter, maybe the cooler is plugged. it is out at Roger Gearharts now, after Macungie when I get back I will check the cooler and turbo out to see if I am loosing boost somewhere.
