[s-cars] Re: Living at altitude - Apexi and turbos

Hap:
My wishfull keyboard.  318rwhp, I believe that was Mance's car IMS.  I'm
tracking these pretty closely stateside.

I'm very intrigued by boost controllers, their function and "claimed gains".
I'm pretty convinced that boost controllers may overcome some of the
shortcomings of the motronic, but I'm most puzzled why one wouldn't throw the
500USD to make the motronic 'better' (it can't anyway).  The shortcomings of
AMBC are pretty well known, and if you are indeed "playing on the edge" as
you claim, then a boost controller is a more dangerous tool than helpful. If
you have rpm input and boost input as your two, then I don't understand the
step backwards.  The Motronic (CAT, boost, rpm, knock, water temp, timing)
is a smarter tool.  Sharpen it, don't use an ax to do scalpel work.  Right
now, one tank of bad gas could = boom.  How does the apexi know?

Big dog stuff needs quantification.  I've enjoyed reading big turbos, big
IC's and boost controllers.  But right now, I've plunked down the weenie
baseline is 400 in full RS2 battle fatigues, no IC, no boost controller.  If
the RS2 MAF limits you to 430, then all the other numbers (IC above ambient
etc) seem restricted in terms of dollars spent/hp ($:HP ratio).

Hap, I only encourage you to move this discussion onto a dyno.  I also
believe 500 is possible, but I'm convinced that will come at the expense of
driveability, unless displacement is added to the equation (yo Mike!).

I enjoy the reads tho
