New performance Slant article in Hot Rod
Bill, is it any way related to spool? As in, is that the same speed range you get full spool and/or boost?
Not particularly as much as the peculiar dynamic that turbo engines exhibit in efficiency
under load. Notice Bill's running 2.76's, and as anyone who has driven a turbo car daily can
attest, they pull stronger on a hill than on the flat. The old "trick" on the FWD cars was to
turn the a/c on "HI" at the line,it would reduce lag on the launch,and the computer auto-
matically kicked off the a/c after it detected WOT for a set duration.
I'm guessing that once Bill's car gets to that point on the track, it hits it's efficiency "stride"
and does what snails do best..PUSH!!
As to why, I have a couple of thermodynamic & mechanical theories, but I'm not 100%
sure. I'm certain there are hands on engineers that can explain the phenomenon, any on
this forum are welcome, but I think we've strayed into that other forum on this..........
