Default Power to weight - performance calculator

Yeah, yeah, you've all seen it before, put plug the numbers in again and see
what it spits out.

My Golf is so low powered and heavy that it falls off the bottom of the
chart, so I added some power and took some weight off. ( added 3bhp, took
off 40kg)

The numbers actually seem quite accurate. Golf Ragtop - as slow as a week in
the jail. Zzzzzzzzzz......

Power at Flywheel (BHP) : 104
Weight without Driver (KG) : 1110
Power to Weight Ratio (BHP Per Ton) : 95.20
0 - 60 (Secs) : 10.83
0 - 100 (Secs) : 36.93
60 - 100 (Secs) : 26.10
Quarter Mile (Secs) : 19.32
Terminal Speed (MPH) : 72.34
Drag Strip Quarter Mile (Secs) : 19.12
Drag Strip Terminal Speed (MPH) : 73.53



Then I put the numbers in for the Sylva - these are much more accurate.
Very accurate actually. Woohoo !!

Power at Flywheel (BHP) : 137
Weight without Driver (KG) : 550
Power to Weight Ratio (BHP Per Ton) : 253.09
0 - 60 (Secs) : 4.58
0 - 100 (Secs) : 12.38
60 - 100 (Secs) : 7.80
Quarter Mile (Secs) : 13.05
Terminal Speed (MPH) : 102.65
Drag Strip Quarter Mile (Secs) : 12.95
Drag Strip Terminal Speed (MPH) : 103.89



In time honoured fashion, your turn.
