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?
