lol
Your car is a drag car
My car has AC and a navigation system
I am running street tires
My clutch was slipping
My headlights were up, causing excess drag
I have a header or boost leak
My tires were spinning, lets roll from 100
Your car looks like ****, mine is the hotness
Just wait until I install my (insert fancy part here)
I left my AC on
My car is still worth more than yours
You have more displacement than I do
It isn't fair you are using nitrous
I don't have the correct gearing
Let's go to Scottsdale and see who pulls more chicks
My drag radials are on backorder
My tires are low on pressure
My car gets better MPG than yours
I left the traction control on
My car will smoke you in the corners
I had more people in the car
I had my schoolbooks and gymbag in the back and it weighed me down
My 10,000 watt stereo is weighing me down
I would have got you if we went to 200mph
I had you off the line

it guessed my car to have 493 at the rear wheels. eh, only 163hp off. :shrug:

edit: lol, this is awesome: You are the Winner! You are Grrrrreat!

i have 299 at the wheels :lol:

578 at the flywheel! and 482 at the wheels bitches

woo-hoo 693 crank horsepower! Not bad! I'm going to cancel my new motor....

OUR DIVISIONAL CAR WAS BOTH CHASSIS AND - MOTOR DYNOED MORE THAN ONCE AND BUY DIFFERENT MACHINES IT DOES NOT MAKE 839 AT THE WHEELS AND 1007 AT THE CRANK -- WEIGHT IS 3065 IT RUNS 145 IN THE QUARTER 720 AT THE CRANK IS REAL -- BUSTERS AND THE GEN 3 CAR I DO THE MOTOR FOR WEIGHT IS 2666 @ 168 ??????????

Who needs a dyno when u have this calculator!!!!!! 456HP to the wheels baby!!!!

Must be my short time keeping me out of the 9's.....

aparently the fiero has 287 at the crank and 240 at the wheels lol and i didnt evan put a mph in yet man it knows my car

Whoa my SS makes 872 to the wheels.....good god

HP from trap speed = 437 RWHP and 524 HP flywheel.

On the dyno I made 315 RWHP

:lol: 907 @ the wheels 1088 @ the flywheel :rofl:

:w00t:

522 at the fly :burnout: looks like i dont need the heads n cam after all

462rwhp maybe i dont need the h/c package to make 450 afterall

545 at the flywheel and 454 rwhp lol

Well, its not that accurate for me "3095lbs w/me, trap speed 148, 893hp at rear wheels, 1,072 at motor, no way!!!! not for a 440" sbc N /A. JR1.

JR....note heavy sarcasm in all above posts.... :D

yes its probably thee most inaccurate in all reality, but check out the bench racing...no matter how many hp your opponent has on you you'll still win :lol:

Well, my dyno-guy told me it's about 844hp @ motor, and 730hp @ wheels, with about 700ft.lbs. torque. that sounds better. JR1.
