Bob,
What are those O2 sensors worth?
George ( down under)
Hi Bill,
I was told by a sales clerk at NAPA that all O2 sensors use the same
thread (I don't know about wide band sensors so this may not apply).
My memory tells me it a 14 mm spark plug thread. My memory is not
always reliable.

Mark,
How do the threads look on the O2 sensor? Mine were boogered up when I
removed it. I still don't know if it is due to different threads or
something else. I used the bung from the original exhaust manifold, but the
O2 sensor that Tracy recommends.

Bill,
The cowl has had the "Dolly Pardon" mod. So, no further cowl modifications
should be necessary. Hopefully, this exhaust system will last. I found one
crack that I hope was caused by not having a support out near the rear. The
HP-2 will be supported for sure. I haven't installed the bung for the O2
sensor yet, plan to do that tomorrow. I need to pick up a new O2 sensor as
mine somehow got damaged.

Took me a minute to figure out what I was looking at, Mark, but what are you
going to do to reinstall the O2 sensor? Looks like you will have to do a
little cowl mod as well?
I sure wish I lived a little closer to your welder. :>) That is a very
clean looking install.

For rotorheads that are contemplating using (also the mildly curious) the
Flowmaster HP-2 "resonator" muffler,
I installed the HP-2 today on my 20B and was able to do a run-up. Bobby
Hughes and I both agree that the exhaust tone is much, much mellower with a
deeper tone. My Lighspeed ANR headset had no problem cancelling out this
low-frequency exhaust tone. While the overall sound level was still pretty
significant, the exhaust tone was much more pleasant to the ears. The
ear-piercing, glass shattering, nails-on-the-chalkboard,
make-you-bleed-from-the-ears, exhaust tone is totally tamed. The 3-blade
M/T prop is the primary noisemaker now. The test took place between two
rows of hangars, so I feel that DB readings are not very realistic. I'll
take those again out on the ramp and post the numbers. If the HP-2 holds up
to the pounding of the rotary's exhaust, I'll be a very happy camper.

They are both used stock Rx-7 turbos. one is the older model pre 89 and
the second is a later model 91 year. They both appear to be in working
condition in no nicks on the blades and they spin. I used compressed air to
spin the compressor wheels to they were really whizzing along.
One came with my 91 turbo block and the other was given to me.

Well,
then we just have to keep on looking for a "justification" for you/your
area/etc. :)
Just wait, I'll find something! :)

How about: "..... I have two turbo sitting in my shop......."
...are they new/used? What's the scoop on them?
