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?
