Seal the compressor cover?

Most turbos I've handled the compressor side fits fairly loose. Has anyone tried to seal the cover to the center? These turbos weren't originally designed for the pressures were running them at so it probably wasn't a big deal. Any thoughts?

free bump.

I'm interested in this info also. As i have seen them with no seal, or with some type of silicon.

Re: Seal the compressor cover?

If your refering to your S4 you got, then don't worry about it. Just clock it and tighten the V-band or cover bolts

Not any charger in particular. The compressor housings are not a tight fit and could leak at high pressures.

Re: Seal the compressor cover?

How much pressure are you running that you are worried about it?

Re: Seal the compressor cover?

My modded H2E is a very nice close fit but it is also only a v clamp without any seal. I figured if a seal is needed then Chris would have added it when he modded my H2E.

So, mine does not have a seal and it holds 53-54psi. Not that I would know if it it is leaking. I don't know anybody that would stick their head into under the hood while it is on a dyno to check it with soapy water.

Re: Seal the compressor cover?

My modded H2E has been to 60psi, like I said I'm not worried about it.

This is my point. Lost pressure is potentially lost power.

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?

Re: Seal the compressor cover?

Kevin, I would talk to your sponsor since he provided the turbo. If there is a seal or way to seal then he should be the one that would know.
