Downhill or Uphill? and it depends on the wind too, but mostly it depends on the weather, snow or rain?
Also , it is faster without police nearby.
And it is faster if is borrowed vs my own.
So, be specific with your question

I might be missing something here but the calcultor does not take into account torque????

Furthermore, a low torque/high power engine (a.k.a. an engine with a high redline) can "create" more torque with gearing.
However, a low power/high torque engine (a.k.a an engine with a low redline) cannot "create" more power.
However, the latter "feels fast," as you can crack the throttle and go in almost any gear. In the former you'll need to downshift to increase RPM.
In the end, regardless of the torque value, power predominantly determines acceleration.

Don't know if you're kidding or if you simply missed the intention of this thread. I'm only referring people to a site that's supposedly calculates 0-60 times "accurately" but any sane person would know there are a lot more factors involved.

Just like it was mentioned a few posts back. Horsepower is a dirved figure of torque x 5250 and divide by some other number Ithat has skipped my brain.
So whoever made this probably plugged that formula in bass akwards to get torque.

Interestingly enough, I read and article a few years ago (I couldn't find it) that determined that you could predict acceleration of a car within about 5% or so using power to weight ratios. This is logical, since you need a certain amount of power to accelerate a given mass.
Obviously, there are other factors, like aerodynamics, drivetrain losses, peaky torque curves, etc. However, these are not as significant, as they are all pretty similar between different cars, as most modern cars use fairly similar technology.
For example, Company A might have an auto transmission with 7% power loss, while company B's model has 10% loss. In the end, this is 3%. You just won't find a modern car with a 30% loss in the tranny.

I must take all my crap out of the car and do a test and only have 1L of petro too and not eat for a day, put the tyre psi up. put back on my stock 17" wheels and it will be faster than now.
