ET's can be affected by shifting and 60' times. With all calculators, they aim at the "best" you could do with x weight and x horsepower. The closest "best" slip I have in that area is Kat running 11.00@122 and it lines up on both sides.

My 60' times are around 2.38/2.47 launch at 1000/1200 rpm.
I posted some more times in the database.
1/8th mile times of 10.40's to 10.50's.

my truck is is .8 and 5mph faster than what the et calc shows 
tune i ran at the track only made 357hp on the dyno but i ran a 13.8 with 1.8x 60's

I would say the dyno was off.
the dyno i went to is claimed to be the most accurate dyno in the state of texas .

i ran 3 tunes on it actually adams, pats and mine.
but my injector pump does flow about 30% less than what a good pump can do

A 13.8 is normal approx. 425 rwhp from what I have seen.
ima replace my cp3 and head back to the dyno for some numbers and then the track.
alot of people say that dyno reads low, but the owner claims its as accurate as can be. best i pulled on it was 382/880 with only holding 21kpsi and 2650pw.
that wasn't a tow tune, it was all my truck could pull out:baby:
TxChristoper pulled 440/1069 with his stock trans lly. We even tested my truck with a G-tech pro RR after the dyno and it was just about spot on. it was only a 10th off my 1/4 and dead on with the mph(95). the G-tech read 374hp and like 2000+ftlbs :rofl:
but after i replace my cp3 ill get the new numbers and try out the calculator again

I know all the posts in this are old, but I'm wondering about the accuracy of this. I ran a 13.14 @ 103.01 mph at 6900lbs 1.867 60', then dynoed 541.2hp the next day. I know there is a correction factor on dyno's, but how would I add this in? All the dyno sheets I have are corrected, and each is using a different correction factor. The only uncorrected #'s I have are on a Dyno running no load, and I only hit 20 psi of boost, brake boosting. The numbers were 544hp. I also weighed the pickup today, at race weight. 6350lbs with me inside.

The calculator is a guess, doesn't mean your overall setup will cut that time. Also, corrected dyno numbers are misleading on the track...you can't correct a 1/4 pass if conditions were unfavorable
I'm just trying to figure out what my real world hp would be, so I can have a guess of what class to run. I ran the estimated time last year, but I think I could do quick diesel this year. Just trying to get a guess. I've done enough suspension work, that if I'm not cutting 1.6 60's, I'm going to cry. If I run what the calculator is telling me, guessing my numbers around 580-600hp, I'll be running right at or below the 12.0 index. Do you guys think that is a just a pipe dream or is it doable?
