Check the sig. ;)  QR25s didn't hit the streets until the '02 model
year.

I know exactly who you are, Wayne.  Weren't you the first to break into
the 14s?  Pat's "SE-R Drag Racing Tips" and Manny Gonzalez' "Front Wheel
Drive Launching Tips" are still on the main site.  Those are two of my
favorite articles to pour over. :)

Ugh.  Yet another thing to retrain myself on.  Green means go, unless
there are three ambers before it, in which case, you go on...

Got it.  I'm thinking about going to test this somewhere this week to
get it dialed in to the precise PSI that puts the most rubber on the
ground.

Great idea, except that it isn't really possible at KCIR. ~:(

AAACK!

Easier said than done is right.  B15s are way more tail-heavy (not to
mention heavier in general), and I'm not confident at all that a 3000
RPM launch would do anything other than vaporize the Firehawks.  1.5
seconds to release the clutch?  My quickest *feeling* (uh, that's also
highly unscientific) launches happen when I take no longer than about .5
.75 seconds to feather the clutch out.

To KCIR's credit, it's never busy, and one can easily get as many runs
in as one would like.  Easily 12 runs in 3 hours if you don't get right
back in line after a run.  Guess I'll have some time on my hands to try
your suggestions. :)
