Probably depends on the size feed line you have. I know BW recommends a -3 feed line on their T4 turbos, -4 feed line on their large frame T6 turbos.

question on you guys running them already and specifically rear mounted, what kind of oil drain flange are you guys running cause the drain flange i got with -10an male end flange is too close to one of the bolts and i cant thread the an line on. do you guys rotate the compressor houseing or do you have some kind of flange that fits better?

I ran -8an for the drain and took out one of the bolts on the compressor side to fit it on there. Since we have oil pumps to drain our oil, we don't necessarily need -10an line. I can take a pic of my oil drain later and post it up

I noticed the same thing. Looks like you may have to tighten the hose end onto the flange first, then bolt the flange to the housing, and clock the housing so a bolt isn't hitting the hose end.

What's the full setup? How much boost were you running? Did it choke out up top on your LQ9? I am worried about the On3 not being sufficient enough on my LQ4.

Seems like it ran out of steam early according to the dyno graph. It's a pretty small turbine for a 6.0L. Also I wonder if the backpressure in the exhaust is opening the wastegate even without the pressure line hooked up? Anyone?

I wonder if going to the 1.15AR housing will help much. I have the same turbo going onto my 5.3L soon, liking these results!

Yeah, not an ideal turbo for a 6.0L. If it doesn't do what I want it to, then I will be upgrading the turbo next year.

NICE!! im not looking for anything near that but makes me feel better that the ON3 is up for the task. since im only looking for 8psi and 550ish out of my t76 ill have plenty on the table left when i decided to up the support mods for bigger power later. but for now a 550ish starting point with bone stock 98 ls1 is all im asking for

It only appears to run out of steam because it blew out the gasket in the merge pipe. Also One of the 3 bolts bolting it to the truck manifold was backed right off.
