Anyone get a VF Engineering Supercharger for Xmas?

Just wondering.

The VF kit looks great, in that:

1) It's a centrifugal compressor.
2) Stock exhaust shield and STB seem to be intact, unmodified.

Issues:

1) Need to send ECU in for chip re-work. Ugh.

Questions:

1) CA CARB EO# ?

Looks like a great kit, it might explain why I've seen
some downward pressure on the price of the JRSC kits.

Cheers -

However, the positive-displacement FM Ubercharger1 is only $3k, fits all
1.8 Miatas (not just the NB), and has a better upgrade path.
Installation probably takes a bit longer, but check out its dyno chart
on the FM website--flat as Kansas. Torquasaurus rex!

Actually, I have a memory that they are problematic. I think it
was reliability issues.

Presumably an issue specifically with the Vortech
compressors?

Don't know. Maybe I am just wrong. MacInnes says the problem
is that they must be driven at very high speed.

My pal around the corner has a Vortech s/c on his Mustang GT.
It is belt-driven on the front of the engine and contains a
transmission to spin the compressor at very high speed. At
idle, the S/C makes a distinctive whistling sound, not unlike
a jet engine at idle.

Certainly he's had no problem with reliability of the compressor
in over a year, for whatever that is worth ;-).

I had one installed this summer. It runs beautifully but the boost comes
on from 4500 to 7000+. It really screams. Feels like a sleeper. Only
problem was some software problems from VF engineering but Nick, the
owner, was helpful. Problems in mine was that it was too new (2004) and
they didn't have software changes for it. It does whistle and I love that
sound!

Result of not having a fixed displacement pump. Boost is low
at low rpm but increases quadratically with engine rpm.
