30-70 UrQ db

[ptimmerm@mashtun.JPL.NASA.GOV]

Here is the latest update, with benchmark data from the literature.
Notice that my car is running as low as 9.3 sec. now with only home
brew modifications  (stage one).  So it runs as fast, or faster than 
the stock euro car, despite extra 350#'s, (12%) That implies that I 
can get about 225 HP (DIN) out of stage one. Also, notice the effect 
of repeat runs due to intercooler temperature. I lost 0.4 seconds from
the first run to the second.  I hope to have a fix for that problem 
before Virgina City.  How many people will be there?
