heading down to Fresno again in the next week or two and I'm thinking I can dothe mileage test again... I would expect high 19's if everything holds the same as the past...

 

you should do an exahust wrap on the exahust mani.... helps the flow of exahust and might increase mpg.

 

I dont think that would be wise with the turbo... EGT's are already way hotter than a gasser...

 

i think even if the stocky airbox got 1 or 2 mpg better its worth the drop for the sound.... but i guess if you were on a long trip i could sacrifice the sound for the dollar savings...

 

yeah there is at least a 1 mpg bump... the egt's take forever to drop though and there is not much top end than with the AFE setup... but hey, lota miles coming up so it'll be worth it to save in the long run.

 

Not on a diesel! The only thing that will achieve is a meltdown!!

ive seen them done on cars that are putting down serious numbers... and they wrap the exahust side of the turbo too.

 

I wrapped the turbo of my 1986 Dodge Daytona Turbo and it eliminated turbo lag. Never had a problem with the engine / turbo, but the drivetrain couldn't take it. That car had a water cooler turbo, is our Cummins water cooled? I thought I read somewhere that its not water cooled.

 

Give a quick recap for those of us too lazy to find the thread. Thanks Steve!

No, the turbo is oil cooled until 2007. Was your Daytona diesel? No, it was gas. The gassers just don't produce the kind of heat that something with 17:1 or more compression does. With Exhaust gas temps in the 1000 deg plus range, keeping that heat in will cause it to build to unacceptably high levels.
Whether the drivetrains can handle what these beasts put out stock is a whole nother story!!
Happy 18th!
