On a good track with a good driver I've seen some car magazine road
tests get a 12.9 @ 108-110 mph in the 1/4.  A more average Joe, with
some practice, should be able to get a sub 13.5.

0-60 times are barely above 5 seconds, usually around 5.1 or 5.2.
Braking is not impressive; stock brakes suck, IMO. I have the 6-speed
manual, and have been told that the automatic is actually quite good,
and offers good launches and is better than a manual unless you really
practice and know what you are doing.

I have a pretty much stock 2000 LS1 5.7 T/A convertible. 6 speed manual.
Since it isn't a WS6, I put a fast-toys ram air kit in it and a K&N intake.
Still running the stock chip, stock exaust and stock everthing else on the
motor and drive train. Installed lower control arms, sub frame connectors
and strut tower brace. That really stiffened it up and made it handle
a -lot- better.  I have not modifyed the chip, stock MAF, etc. K&N intake.
It's pretty much box stock.

Out side of Dumas Texas (real flat-low altitude) I have had it up to a GPS
corrected 145 mph and it was still climbing fairly well. I'm pretty sure if
some one had the guts and could afford the speeding ticket, it would of gone
150-155mph. At 5,200' above sea level where I live, I can get13.4 in the
quarter at 108mph. 0-60 in 5.1 seconds and it blows the doors off a Rousch
supercharged Mustang dragging stop lights (waxed him 3 out of 3, but his
exaust was MUCH louder than mine-he attracted cops-4.6 liters just ain't
enough). I don't drag race all that much <any more>, but I'm pretty sure
you'd have to go a long ways to find any kind of a 4.6 liter Mustang that
would touch it.

I keep thinking some day I'd like to put a procharger on it, but there is no
one around here I would trust to do it. It's a lot of fun and pretty quick
stock Certainly the most "bang for the buck". I have 42,000 mile on it. It
doesn't come out of the garage unless the top is down so inside and out it
is pristine.

It seems like I read years ago in a top 15 sports car shoot out that a 200X
WS6 TA would top out at 163mph. That's under ideal track conditions. I have
a friend who has a 1999 WS6 that he says he's gone 155mph in. He's been a
hot rodder since we were 16. That was 45 years and many hot cars ago. He's
never had reason to lie about any of the many fast cars he's owned.

There are web sites that F-Body LSX owners post thier time slips on. There
are lots of LS1's with just a little tweaking turn the quarter in the sub
13's. I think a 5 second 0-60 is pretty much what they do.
