what can i expect out of a stock 98 cobra coupe?

 

ET and MPH?

 

the SVT book that comes with the car says 13.99 1/4 mile. I don't remember the speed though.

 

mid-13s @ 103 are doable with a good driver. I went 13.6 @ 102 with a 2.0 short time factory stock in my 97 (way back in 1997) and the 98s were a little quicker. Best I ever heard from a factory stock 98 was 13.08 @ 106.

 

if its your first time at the track upper 13's, maby very low 14's
