Default Drag times Vs Power

Hey guys,

Is there a rough guide for what quarter miles times you should/could run for a power to weight ratio?

eg, 200 horsepower(atw) per tonne gives you 14 second quarters
400 horsepower gives you 11 second quarter....(just an example)

Cheers,
Steve.

Yeah there are a few online calculators that can work it out. I'll see if I can find them.

Edit:

Sites like:
http://www.turbofast.com.au/Drag.html
http://www.hardcore50.com/members/calculators.htm

They only give a rough indication though (as there are so many factors in a time). I'm sure a google of 'drag calculator' will yield some more.

as a rule, the more power you have, you should get a better time : )

This has been proven wrong though from time to time.....Something to do with the driver...

Not sure exactly on weight- i just put 1500kg (3300 pounds).

Jaron- how much HP you entering? I wouldn't have thought a bloke pushing an STI up the strip would be that quick? Sorry...
