If you could squeeze 20 to 30 bhp out without adding weight you should break into the 13's
Power at Flywheel (BHP) : 296
Weight without Driver (KG) : 1525
Power to Weight Ratio (BHP Per Ton) : 197.21
0 - 60 (Secs) : 5.56
0 - 100 (Secs) : 13.38
60 - 100 (Secs) : 7.82
Quarter Mile (Secs) : 13.87
Terminal Speed (MPH) : 101.80
Drag Strip Quarter Mile (Secs) : 13.77
Drag Strip Terminal Speed (MPH) : 102.95
You lowest bhp and weight gain would give you the following
Power at Flywheel (BHP) : 291
Weight without Driver (KG) : 1538
Power to Weight Ratio (BHP Per Ton) : 192.24
0 - 60 (Secs) : 5.68
0 - 100 (Secs) : 13.75
60 - 100 (Secs) : 8.07
Quarter Mile (Secs) : 13.99
Terminal Speed (MPH) : 100.86
Drag Strip Quarter Mile (Secs) : 13.89
Drag Strip Terminal Speed (MPH) : 101.99
But you would need to get a mapping done, plus HF cats, plenum, and zorst and maybe you would hit the 20 and if mapped could break the 13's, figures above are a bit hopefull but
