i think your right the s4 is not stock...
i dont think that s4's run 8.2 in 1/8 mile stock but i could be wrong. it didnt sound stock anyway.
I dont think the tb would have beat him in the 1/4, the s4 killed him in the 1/8
its an s4 what do you expect in an 1/8 mile, i bet the tb would have ran him down in the 1/4 mile
