'02 WS6 - bolt-ons, tuning, bone stock long block LS1, N/A

In 2002 we took a stock '02 WS6 Trans Am and used it to develop our LS1 X-Package.  With nothing more than our engineered combination of external bolt-ons and plenty of dyno tuning the car made 400.7 rwhp and 401.6 rwtq.  This is the first and only bolt-ons only LS1 in the world to get to 400 rwhp.  We call this engineered combination of bolt-ons the X package.  To learn more about this LS1 world record check out the X-Package page.
