My old 1.6 16v nova

Power at Flywheel (BHP) : 193
Weight without Driver (KG) : 625
Power to Weight Ratio (BHP Per Ton) : 313.76
0 - 60 (Secs) : 4.54
0 - 100 (Secs) : 11.23
60 - 100 (Secs) : 6.69
Quarter Mile (Secs) : 12.95
Terminal Speed (MPH) : 107.38
Drag Strip Quarter Mile (Secs) : 12.75
Drag Strip Terminal Speed (MPH) : 109.42

Drag strip terminal was actually around 102mph and 13.8 qtr mile, the calculator is a bit shite for times and speeds IMO.

So i take it you know an exact(or near enough) power figure for your car now Nic that you can comment on how innacurate the calculator is??

And what did your car weigh when you had it weighed after fitting the cage etc??

Or are you just pulling numbers from thin air??

About you pulling numbers from thin air.

The calculations will be wrong if you dont know the figures in the 1st place.
