me too. that thing is BS.

How much are you using for weight.

Anyone know how on/off the aeroforce hp gauge is. It's flywheel too right?

Kind of funny how I punch in 240WHP and a weight of 3,200 and I come up with a 13.8? I am assuming your car is about 3,000 and adding 200 for driver. Now these calculators are not 100% but they are usually with in a couple of tenths and don't take into consideration variables such as wheelspin or poor driving. I mean it's just a math calculation based on the power to weight ratio. Hey Asstyme I am from Janesville too.

get drag radials and the times would be more realistic in real life as well

I guess using one of these calculators means you need to know a little bit about cars.......

By the way I have no idea how much power your car is rated at stock- my guess is about 160 HP at the crank is about right?

haha... you say it's for people that know about cars, then say a fwd car only has 5-7% loss?? and it doesn't say anything on that page about it being for a rwd v8

It says i should be running 13.55 and I ran a 13.62. Im guessing im pushing 250hp it says im pushing 248. Seems alright to me.

i think its a solid guess...

over the weekend with half tank of gas and me in it my car was 3160lbs

i put that in and my guestamated(sp?) hp and it gave me 12.6's...so with rob and a few others that i'm on the tuneing/moding level runing 12.80's i'd say this thing is dam close!

How much HP u think ur pushing.....im guessing 280 which is 13.0-13.1. Where are you getting 12.6? 310 hp? All on this ricer calculator of course.

Says this at the bottom of the 1st block...

"This calculator esitmates your quarter-mile elapsed time (E.T.) when given the weight of the vehicle and flywheel or "at the wheels" horsepower. A 17% driveline loss is assumed for flywheel HP."

I would assume 17% means RWD

Yes, 17% is for rear drive- and an automatic will lose more than a stick, a high stall converter will eat a lot too, so will big transmissions such as a turbo 400 verses a turbo 350 and a Dana 60 verses a 10 bolt. You can buy a desktop dyno program that really can dial in on things and predict how changes will affect things.

I hope that calculator is right. With 3000 lbs. and the 271 WHP I dynoed in 4th gear, I got a time of 12.9 and with the 274 WHP I dynoed in 3rd gear I got a time of 12.8. Not bad at all.

With traction and a good run I would think you would be pretty close but don't forget the conditions at the track might be a little different that at the dyno. How did you get the car's weight down to 3000? Hope you get yourself a 12.
