I don't know....... I saw a 01 ws6 run a high twelve bone stock.... even the stock air filter... (this guy was a GOOD driver)!!!! THe ls1's are pretty fast, my best friend has a 00 ws6 and can run a consistant 12.8 with only a underdrive pulley, air filter and flows on drag radials.... Becareful, if he is a good driver he might beat you. Good luck though!!
