Interesting.
My previous Volvo 850 T5 should, in accordance to the calculator, do a mid 5 to 60 and 13.7 1/4 mile. Thanks to a lack of traction it is a bout 0.5 of a second out.
My second test was my Skoda Fabia vRS. I only have the WHP which is 160 so I assumed we are talking 185 at the crank. I competed in the tuner GP 2005 in that car and won my class with a 6.6 0-60 and 15.2 1/4 mile. It is 1 second out 0-60 and 0.4 seconds out 1/4 mile [I have to change gear 3 times]. So it is more for n/a petrol's I guess.
Like the Fiat Coupe guy, the Volvo's midrange was just silly
