Mack superdog Posted December 27, 2022 Share Posted December 27, 2022 I have an e9 noticed I’m starting to get a little oil residue on the cold side can anyone tell me what turbo this is I don’t think it’s stock considering it pushes 36psi on a warm day and 40psi on a cold day i know stock should only be 28psi these are the only numbers I can find there’s no tag where they normally are Quote Link to comment https://www.bigmacktrucks.com/topic/70934-e9-turbo/ Share on other sites More sharing options...
BOBWhite Posted December 27, 2022 Share Posted December 27, 2022 As a last result you may have to take it out and measure inlet diameter, turbine diameter, and exhaust housing diameter to find a similar turbo. It could have been ordered from a catalog that's long gone by now. Do you want to go back to a stock turbo or do you want to find whatever turbo is on there?

fjh Posted December 27, 2022 Share Posted December 27, 2022 I don’t know where you live how ever if you got a local fuel shop you might want to check with them! Also mak sure your air filter is clean this has caused issues in the past specially with a high output turbo and fueled up engines! In the land of oz the v8 was or could produce 650-700 hp we installed an ozy turbo on several trucks here and as your observation 35-40 psi boost was not uncommon! Just tweaked the fuel to the need! Note the drain tube was a little different so beware! 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70934-e9-turbo/#findComment-519158 Share on other sites More sharing options...
Mark T Posted December 27, 2022 Share Posted December 27, 2022 Might just have a leaky charge air cooler. I've seen normal E9s get up in the mid 30 PSI range when they're in good shape.

The Rubber Duck 006 Posted December 28, 2022 Share Posted December 28, 2022 Hmm I would say that psi wouldn't be uncommon for a big V8. I had a 515hp Detroit 60's series in my 2005 Freightliner Coronado that would push almost 50psi at times under a pull. Sounded like a 747 gittin ready for take off when you fired her up lol.

Yes it’s in a dump truck I change the air filter once a month as preventative maintenance and yes the drain tube looks like a accordion Quote Link to comment https://www.bigmacktrucks.com/topic/70934-e9-turbo/#findComment-519168 Share on other sites More sharing options...
fjh Posted December 28, 2022 Share Posted December 28, 2022 They all do even stock turbo? The lengths are different! Quote Link to comment https://www.bigmacktrucks.com/topic/70934-e9-turbo/#findComment-519170 Share on other sites More sharing options...
