FYI.  I thought this was a great page, and very useful.  I'm expecting my
Fuel/Air gauge this week.  I bought a CB products analog gauge for about $50
along with a spark plug antifouler and an O2 sensor for an '87 Nissan 300ZX.
The sensor was about $50 from autozone (A three wire Bosch Unit).  Well,  I
actually have my old one from my 300ZX.  I'll get the new one next month.

Try http://www.cbperformance.com/catalog.asp?ProductID=598 for the gauge.

Glen,  this might prove to be quite useful for setting up your Turbo Bugeye.

Mike

This link is to an excellent web article on selecting SU needles using an
air/fuel gauge.  This is why I think the gauge is so usefull.  If you've
ever
considered trying to optimize the needle selection for your particular
engine,
this web page is vital reading.  Not only for the knowledge you will gain,
but for the software in it.  

The SU Needle spreadsheet program is there for determining your needle 
profile at each station, but for selecting other profiles.  Good stuff!  I
sucked 
it into an Excell spreadsheet so I could have the pretty lines to admire in
a 
graph.  I'm a visual sort of guy, so I can grasp lines far quicker then I
can 
grasp a column of numbers.

Lastly, if this inspires you to want to install an air/fuel gauge, I suggest
you
at least look at this link.

It's about $65 now, which is roughly twice as much as a digital one costs,
but boy is this thing pretty, and right in keeping with a Spitfires analog
gauges.
