That is supposed to be a 7FB11559 3406B 400 HP with an OR-6958 turbo. It's non wastegated, and a little lazy down low. It works GREAT at about 1700RPM though.

I am trying to get my boss to buy an OR-7202 from a 3406E 435 HP. It's wastegated, and where my engine was tweaked it will have NO problem spinning that bigger turbo. Where it is wastegated, I can set the gate to 28 PSI and forget about it. I have a pyro, and it never gets above 950* and the truck rarely ever sees more than 30 PSI where I run it in the RPM range.

An OR-7202 with a wastegate set to 28 PSI would make this engine so much more usable from 1100 RPM to 1500RPM where I like to run it at....sweet spot being 1300 - 1600 RPM

Well,...try THIS on for size. We got a turbo, that was SUPPOSED to be off a 425 horsepower 3406B...I thought it looked a little big. The exhaust housing the the same .75 AR housing as the other turbos, BUT the intake side's compressor housing is MASSIVE!!!

I bolted it on, and the power was a little better, but it seemed to lag a bit. It shouldn't do this, but when I lay into her it spools up fairly nice.

Know why?






It's a turbo off a 3408...1100 cubic inches, 18 liters and 8 cylinder....MASSIVE!

He wants to leave it on there, what do you guys think? Turn the screws a little and run it with the added fuel?
