My car is 1 of 120 WS6 TA 6 speed convertibles built in 1997. It is also the only year that the LT1 WS6 convertible was built.
I have since added a Pro 5.0 shifter, FLP longtube headers, LT4KM, 3.73 GM gears, Borla catback, Meziere electric waterpump and converted to OBDI PCM to do my own tuning. The car dyno'd 292.8 RWHP and 328.5 RWTQ in March 2002. My best track time for that setup is 13.35 @ 104.84 MPH with a 2.08 60'. Best MPH is 104.99.
New Best. 3/14/2004
Went to Richmond Dragway and pulled an 11.96 @ 118 (117.99) mph with a 1.85 60' on a borrowed set of skinny's. Temp was 60 degrees during the run.

OH SO CLOSE but no new best. :(
After installing a BMR K-member and switching to a 4.10 gear I ran
again at VMP in Dinwiddie, VA. With the ZR1's at all 4 corners 17/275's up front and 17/315 Nitto's on the back I ran 11.97 @ 117.84.
I also ran 12.01 @ 117.83 and a 12.03 @ 117.83 matter of fact all of my runs were 11.9-12.0. 5 in all, 3 of which are in video online. Temps were in upper 70's DA was about +1600.
Here are my runs on Sept 25. Click each time to watch the video.
Check back later this season. I plan on getting my own set of skinny's
and running in hopefully some great fall racing weather. Hoping for 11.8's @ 119 and maybe.....just maybe.....120mph. :)
Skinny's are ordered, delivery scheduled on Oct 4, 2004. Woohoo :)
I will still run the 17/315 Nitto's on the backside.
New Best Nov. 5 2004,
Went to VMP for Friday night racing and pulled an 11.790 @ 119.53 with a 1.83 60'. I let James take the car for a trip down the 1/4 and he spun to much in the 60' to beat my ET but he did pull a new best for the car on the big end with 27.55 mph. My best is 26.xx. I ran skinny's up front and 17x11 ZR1's and 315 Nitto drag radials on the rear.
UPDATE NOV 15 2004
I took the car to an EFA event at Maryland International Raceway (MIR). New best is 11.73 @ 119.95 mph on a 1.76 60'. I also had two runs of 11.8 at 120 mph for both runs. The car was run with skinny's and the ZR1/315 Nitto Drag Radials.

5 years have passed and the car is running great. What a great setup
for power and longevity.

Running GREAT! Might take her to Pontiacs in the Park 2009 for the car show.
March 3, 2011
2 years since last update?!? Where does the time go?
Took the car to Pontiacs in the Park last year and brought home a trophy. Also took it on a road trip and pulled 25 mpg! Not bad for
an 11 second vert.
March 1,. 2012
Installed a Magnaflow muffler in place of the Borla muffler.
The Magnaflow creates a deeper tone with no drone.
Dec 2014
Car running well but now has an oil leak, thought for sure it was at the back of the pan. Guess it could be the rear main. Need to check the infamous intake leak or possibly oil pressure sensor.

2 failures at the same time. ignition switch (under the dash) and fuel pump. I did have small signs the pump was going. Ignition switch just gave up. I dropped in a Racetronix RXP 255L fuel pump and the ignition was a factory GM replacement. The car is running great and still looks like new. She turned 20 years old in April. At 25 I'll put classic plates on her. Time sure flies.
