On3 Billet 7675 BMF I haven't really looked at the chinese Turbos, but this one has caught my eye a bit - the bad ***** f'er. It's a larger 75mm turbine housing .96 A/R T4 3" v-band with a billet 76mm compressor, 4" inlet and 3" outlet. Also is plumbed with the 1/8" NPT and can be coated.
Price is creeping up closer to the Turbonetics and Comp journal bearing stuff at 899. If this had a ball bearing for that price, it'd be hard to beat.
But On3 claims it's doing 830rwhp at 15psi on a Coyote. That seems really good.
What do you guys think? I was really leaning toward the Comp Billet 7875 BBB deal Huron sells. It's slightly larger T4 1.15 A/R with the 3" v-band on the turbine and 4" inlet and 3" outlet on the compressor (so an upgrade say vs a Turbonetics 7875).

If you really want a Chinese T4 turbo then I would look at the VS T4 80mm with the 88/96 exhaust wheel. Slightly more expensive but will go a LOT further then the 75mm wheel on the turbo you mention. If price is a concern just get the 75mm compressor with the same 88/96 wheel, still be better then being choked by the 75mm exhaust.

hijack,
you think the VSR t4 stuff with the 75mm turbine wheel in the larger A/R's is gonna do much to help with back pressure?
looking to replace my 7875 when i swap my 6.0 back in place of the 4.8

It is. Here's a video comparing.
The issue is the turbine is the same size. Needs more turbine.
Btw, Huron seems to be using the same cover - it's a 3" outlet vs the 2.5" outlet typically seen on these size turbos.

I was just checking out there instagram looking for more info on the BMF and noticed they are coming out with s400 style turbos soon. Not to suprising right? Also saw on there they are making a 94 and 106 mm. Supposed to be out in december.

If your replacing anyway why not step up in wheel size? I don't think the AR itself is going to help all that much.
