Re: Seal the compressor cover?
Admittedly, I haven't seen many turbos apart except for the stock/van turbo, but I would have thought there's some kind of seal. The stock ones do have that big o-ring around the compressor backplate, but they don't see the same pressures larger turbos do, and with a fitted, non-clockable housing, it will attach differently too. Interesting thought Kevin. I'm curious too now.
I'm wondering if the expansion of metal due to heat doesn't create a tight enough seal to not leak? Turbos are assembled at room temp, yet get heated up when the truck runs. The compressor side can heat up the air to what, 400*? How much of that heat get's transferred to the housing?
