[urq] RS2 Update

[Pasqualoni, James E]

Hey Guys,

I have not yet tested extensively, as I don't feel comfortable doing so
until I can get all of my instrumentation up and running (especially EGT).
Yes, fuel is a concern here.  I could pump that baby up with an EFI system,
I'm sure.  But for now, she feels PLENTY fast.  Definitely faster than my
old Dahlback RS2'd urS6 Avant.  15 psi is literally a breeze with this turbo
(Brandon-you have a IA RS2 in your 20v, no?).  In my case, it's all about
efficiency.  Target number for this application is 300 crank hp.  She
definitely pulls harder above 5k rpm, but I haven't pushed red-line at full
boost yet.  I'll let you know how she does once I am comfortably monitoring
EGTs and oil temp.  

There is still a fuel cut-off at red-line.  One thing to note is that the
stoich gauge is staying to the rich side throughout the RPM range-so far, so
good as far as mixture goes.  As you mention, I have to be comfortable that
everything is working as it should before I start pushing limits.  I will be
reporting back as things move forward.

Jim

Yeah, what's the box capable of?  Obviously, you don't want to go lean and
don't want to hit the fuel cutoff prematurely, either --or is there no
longer a fuel cutoff?
