I know this question is repeatly asked but few fit my situation.
I have a 94 f350 7.3 idi factory turbo, boost gauge and a 6" offset stack (straight piped). The truck is loud but i just can't seem to be able to hear that turbo at all, i have a boost gauge and im pushing about 8-10 psi but no turbo sound. I have heard that the downpipe off the turbo has alot to do with that, but i can't seem to find out where to acquire one, it seems pretty farfetched for a downpipe to my it so quiet i can't hear it. Any help/ advise would be great. Thanks

 

get a hypermax cowl induction kit(bout 80 bucks) and banks sells upgraded downpipes for the factory setups. they dont list it on the site but call them up. they have em.

 

D.C. or anyone else,
What sound does the turbo make or what signs (if any) does it give you if it is going out?

Thanks,

lots of smoke, low boost, high egt's if it locks up. 8lbs isnt very much not very much at all 15 sounds better

 

the factory turbo setup is set for 8 psi wastegated. some do creep up to 10 lbs.

 

Im completely content with 8lbs of boost, because I know how much money is involved in acquiring more boost. Is it possible to make your own down pipe? Lets sa
y outta flew pipe and a mig?

 

some turbos have a metal silencer ring held in by a metal c clip you 'll see it if you take the intake tube off the turbo. it looks like its part of the turbo. i know all the cummins have them once removed it sounds like a kenworth. wisslin dixie

 

we dont have the scilencer ring.


as for the down pipe, some guys have bought OBS stroker down pipes, cut the flange off and adapted the original flange to the bigger pipe. bingo, 3in down pipe.

 

Does the Banks setup for the '88 7.3 IDI have a silencer ring?

 

Just an update. I made my own downpipe, it turned out pretty good ill post some pictures in my prof.
