If you really want to keep your vacuum gyros and not upgrade to electric=2C
then I think that the best bet today is the Sigma-Tek piston pump.

Excellent reminder. Also, if that Rapco only had 300 hours on it, I hope
you kept the warranty card, as if I recall correctly they are warranted
for 1000. Also, if you are getting any oil around the pump it can cause
drag that will break the shear coupling.
Of the standard design, Tempest and Rapco are the best made. There are
fit issues with the oil separator necessary for wet pumps, and fit
issues with the Sigmatek piston pump. If you have the space to install
them correctly, I'm sure they are fine, but many aircraft don't have the
room.

| Subject: | Flight Test Plan - Thanks. |
My thanks to all those who reviewed my flight test plan. While most of
the suggestions were already incorporated in my plan, there were a couple
good ideas (like reminding me to keep the climb-out very shallow for
cooling).
My plan of making my ground crew "manage" the flight worked Very Well for
me. He was responsible for prompting me and recording all the engine data,
reminding me when to land (when my 30 minutes expired - or if my CHTs got
above 425) and pulling/cutting me out of the plane in an emergency. Because
he did all the logging, all I had to do was fly. My mission was to
concentrate on flying: basic handling and try 2 stalls (clean and 20%
flaps). The Chase crews jobs was simply to keep me close/far enough from
the airport, to look me over (no fluids or flapping parts), do a speed check
with me, and to mark the crash site for Ground/Emergency if I went down.
Everyone understood chatter was to be kept to a minimum.
The RV-7A flew exactly as advertised and how I expected it to. It's Very
Quick and it's light on the controls. It is pretty pitch sensitive. The
landing was easy - actually a "greaser". The only unexpected development was
the noise. With no upholstery/carpet and only bare metal at this stage, it's
LOUD in there blasting around the pattern at 75% power. I guess I should've
expected that sitting in a metal can next to a no-muffler exhaust. Even my
ANR headsets didn't help enough. I may stick some carpet in there before I
fly it again to see how much it helps.

Lets see here...spend multiple thousands of dollars on solid state stuff
and more thousands on EFIS to replace a $200 pump and $600 gyro. Then
spend another grand for separate alternator, battery and essential bus
to have totally separate systems as required for IFR. Always easy to
spend other's money. ;-)

A little snippy there Finch. Actually I've been flying for forty years
and have had only one vac pump failure and that was in VFR conditions
which is what I'm rated for. Nothing unsafe there. Believe it or not,
there's actually some of us out here who don't have unlimited funds, as
apparently you do, who are grateful to be able to just build and fly a
machine with older technology. But if I made a habit of bungling into
IFR I'd probably make some changes in my system, but I don't, so I
agree with Kelly; why spend a bunch of money on a system I don't need?
Frankly, I'd rather spend my limited flying funds on avgas rather than
an expensive system that I don't need...or want.

I flew IFR for 20 years with two vacuum gyros, powered by venturis. They
make a vacuum pump look extremely reliable. These days it is easy to
have a setup with only one vacuum gyro and two electric for not much
more money. Losing only one gyro in IMC shouldn't cause a competent
pilot to even break a sweat. Certainly less of an issue than losing a
glass panel in IMC.
