I'm with TTT, exactly what are you looking for data wise?

Do you want the housings sent to you?

Is it ok to disassemble the engine, take four pictures per housing (oil injector, exhaust port, compression area + Trailing plug, hole leading plug hole + expansion area) and post them here?

Do you want a glowing write-up, measurements, etc.?

The housing price seems realistic, the data deposit seems rather low to expect anyone to actually remove and disassemble their engine. Maybe compression readings would be sufficient?

I am willing to pull the engine, disassemble it and take pictures for posterity and the sake of research (no money involved), but I wouldn't disassemble it for $200.00, it would cost me almost that much in gaskets and seals.

That's the blunt way of making my point

In addition to some of the specs in my last post yes those pictures would be perfect. I don't know that all measurements are needed as long as they are within factory specs. A lot of the clearances simply do not apply to how the housing chrome stands up. I guess if binding corner seals were a problem that would affect the result.

Yes at first they would be sufficient but at some point the engine would have to come down for a look.

You don't have to tear it down but then we keep the $200 data deposit.
Maybe we are getting ahead of ourselves. I wouldn't expect you to tear it down right away anyhow. The longer together the better as long is everything is working properly.

I have housings that have apex seal damage. Almost all of them have corner triangle chrome flake? I thought the purpose of rechroming was to get this fixed? So the quality of this rechroming only reflects the quality of the housings to begin with? Is there going to be pictures of acceptable housings vs unacceptable?

For me I would want to try my worst set But I have two new engines sitting in my cars now so hopefully no need for new housings right this year Mind you the track is pretty rough.....

It reflects the quality of the insert. If you've got housings with major gouges or pitting where chrome is missing then you will want to wait for when we offer the repair service as well.

As a matter of fact yes there has been. We just received yesterday the final pc we've been waiting for. Now it's a matter of some serious machine work and off we go.

The first pair of housings we will do are a pair of S6 housings (pics on pg 2)that came from my engine when I bought the car. They are in decent shape for re-chrome with scratches in the centre around the plugs, chatter and some wedge wear.

Of course I will post as soon as I have them done.
