If you want to calculate your 1/4 mile and 0-60 time (or estimate your HP) this is a great calculator it even compensates for altitude

not really LS specific, moved to car chat

 

I typed in stock specs from my SC300...and its pretty damn close, +/- a second.

 

Impressive. Pretty close.

 

How can it be accurate when it doesn't take drivetrain into consideration? With the same car and high horsepower... AWD is definitely going to yield better times than RWD.

 

Fun, but I don't like my results

 

Here is how I use it. Adjust your sea level 0 to60 acceleration to what your car does per tested specs (car magazines, ect...) then put the altitude you are at and it will tell you what your 0 to 60 should be at your altitude for your car. So use it as an altitude adjustment program.

 

seems pretty damn accurate when I punch in the numbers for my LS

 

Make sure you pick higher torque than horsepower setting if you have a Lexus v8 not sure on the other engines
