Me and a friend are arguing about this mazda with a turbo that he "knows for a fact is in the 12's" because of this calculator, and some 'dyno' sheets, i checked it, and its not very accurate to me.. but i dont have dyno proven power, and unfortunately hes 1000 miles away so he can run his mouth all he wants cuz he knows i wont be able to see the 'dyno' sheets, so heres the question, how accurate is this? it was .5 off between the 2 calculators on the page http://www.battleoftheimports.com/classes/battlecalc.htm
Well, that agrees completely with the ET figures I got out of a spreadsheet I wrote up. I mean like, down to the 100,000th's of a second. Thus, they are probably using the same formula I am. I went by this wheel horsepower formula for my sheet: ((weight/WHP)^(1/3))*5.825=ET (The cube root of weight divided by horsepower, multiplied by 5.825) I checked it using a 3454lb car (stock weight GN) with 500 horsepower at the wheels. This should run an 11.09379252 at 123MPH, and their calc checks out on that. Likewise, when I paste in the ET and weight into their second calculator, it comes out at 500.00 WHP just like it should. But, that's all math. Cut a bad light or run on a greasy track and your 11 second car is still in the 13's. o No: - Freed
