Some examples to show you how far off you are:
stage 2 B5 S4s
the GIAC and APR tuned records were low 13s to very high 12s at 105-108 mph
JHM tuned the B5 and Dan@JHM went 12.28 @ 112 mph (no APR or GIAC car ever came close)
K04 B5 S4s
the GIAC and APR tuned stage 3 cars went mid 12s to high 11s @ 114-118
JHM tuned the B5 K04 setups and ran 11.1 @ 129 MPH (no APR or GIAC car ever came close)
B6/7 S4s
the fastest GIAC or APR B67 S4 (naturally aspirated) was 13.21 @ 103 mph (APR car)
the fastest JHM tuned B67 S4 (naturally aspirated) was 12.70 @ 111 mph (no APR or GIAC car ever came close)
B8 S5
the fastest APR or GIAC B8 S5 (naturally aspirated) was 13.2 @ 103
the fastest JHM B8 S5 (naturally aspirated) was 12.60 @ 108 (no APR or GIAC car ever came close)
Want any more? Those gaps are massive. The average ET gap is 6 tenths. The average MPH gap is 8 MPH. A car that wins by about 5 tenths at the strip wins by about 5 car lengths. If they did a highway pull, that translates to about 8-10 lengths. All of those examples are greater than that difference.
