I heard someone talking about Dyno numbers and 1/4 mile times, and how the HP can be calculated better by using the 1/4 mile info as opposed to the Dyno info. We have all heard different dyno's giving diferent information and some of you think Dyno #'s mean nothing... just put it on the track and the 1/4 mile times dont lie.

Since I dont know how true this is I am going to ask for some help from those of you that have Dyno'ed and Run the quarter mile in your truck! I have never had my truck on a Dyno so I dont know of the numbers I am getting are very acurate! If nothing else this tool is fun to play with...

ET was 664 hp
Mph was 589 hp

The ET method is way off but sounds alot better.

According to my Edge juice w/Att my 1/4mile time is 14.6 @ 91mph but I dont know how accurate that is either! Just wondering who has Dyno #s they can compare with these ET and MPH calculations. You'll also have to know what you truck weighs.

I wish I could find a local dyno I could believe in.

Thanks for posting that link for the Members! I had seen that some time ago but never wrote it down.

Here are my calculations:

My 1996 Dodge CTD weighs 6,824 lbs.
Best E.T. Ever is: 11.52
Best MPH Ever is: 118

Here is what the link said by plugging in my time and MPH:

E.T. : 882 Horespower
SPEED: 875 Horespower

FWIW, my numbers are pretty close as I dynoed 891 H.P. at "Fall Brawl" and that link says 882 by the E.T. That's pretty good................................

i've dyno'd mine before and it would be runnin a 13.6 on here.... now i put my buddies numbers in here off his d-max and it calculated about an extra 130 horse or the dyno wasn't right..

Thats what I wanted to know! Thanks a bunch... looks like I am right around 430hp.

Thanks,

JESUS!!! 8700lbs??? Are you sure about that?

I Had my truck weighed at a DOT scale and it was 8000 w/o anytools and a 1/4 tank.

I made a impromptu pass at the truck and it was all loaded up. I'm pretty sure. Maybe just 8,400...
