performance calculator..... BHP per ton etc
Discussion
Being a bit bored, and seeing the "what's the lowest weight ultima" made me think about how much weight actually affects performance.
This site : http://www.letstorquebhp.com/calculator.asp
Not sure if it is accurate but....
EG: My spyder weighs 850kgs and was rolling roaded recently at 357.5 hp at the flywheel (zz4 carb SBC)
The calculator says:
Power at Flywheel (BHP) : 358
Weight without Driver (KG) : 850
Power to Weight Ratio (BHP Per Ton) : 427.94
0 - 60 (Secs) : 3.41
0 - 100 (Secs) : 8.00
60 - 100 (Secs) : 4.59
Quarter Mile (Secs) : 11.65
Terminal Speed (MPH) : 120.69
Drag Strip Quarter Mile (Secs) : 11.55
Drag Strip Terminal Speed (MPH) : 122.11
which is not far wrong. My best Qtr mile is 12 secs (slow reaction times etc?)
worth a play if your bored!

not happy with that quarter mile time!! but hopefully we will see

They have a page explaining thier calculation technique here.

Basically, averaging from similar cars

There's a few Ultimas in there.....
