That's what I am hoping. I plan to push two of them pretty hard but will be at least the end of the year before my build will be running

anybody got any picks of one took a part yet
imo from the looks of it, an from some of what I've been told by some of the turbo gurus on here about China turbos
it is probably a clone of older garret/honeywell wheel designs
with a mix of turbonetics

it has SERIOUS trouble getting over 500whp and is capped off at near 550, so it will be interesting to see how much more i can get out of the 78/75
Subscribed for results.

Shouldn't this be better than the master power t76 unit? I'm pretty sure they have a 6Xmm turbine wheel.....

Correct, the MP 76 and the on3 76 are almost identical turbos

You don't need that small of a back housing on a motor that size. Build the motor properly and get a cam that is spec'd for them and they should have no issues. I guess I will have some first hand data on that when my car is completed

Looking forward for results. The only thing holding them back before was the tiny turbine. While this one is not huge, it should be great for the 5.3/4.8 crowd.

swapped it on a 500whp on3 equipped built 6.0 truck and it makes nearly the same power as the 76 at the same boost levels, just makes slightly more hp

honestly not sure whats up with that, might be something else in the setup?

i also have a KB racing manifold and billet turbo on the way for this truck

You would think it would make more power all over though, regardless of boost
