I'd agree with that. Maybe a little quiker if the track has a great launch pad, you perfect your launch technic etc. My auto with 3:15s was 13.3 @ 105. I havent run my 6 speed because our track closed before i got the 6 speed car.
Also keep in mind, the 01 up c5 6 speeds have a slightly larger cam to boost torque to 365ft pounds, a 83mm tbody, and a z06 type intake manifold, and the torque tube was upgraded and alot stronger, so the times will be a little quiker than 97 to 00 c5s.
If you toss the run flat tires, your 60ft times will improve just from that alone.
