The #s came out pretty goo for me too. I think I am near 300 RWHP, add to it a 85 nitrous shot.

I weigh in at 5300+ w/ driver. Trap of almost 97 gives me 377 on your calculator.

Has anyone else noticed that when you have less traction and slower 60' times that your MPH is higher?

i wouldnt know about that, ive never had traction haha.

looking at my timeslips, mine just look random, no real relation. but the last time out to motorplex for me was the division 4 e.t. finals, im thinking the track was prepped WAYY better that time, because most of my 60fts were in either 2.4s or low 2.5s. still not good, but better than 2.6s.

raising my shift point on hypertech from +5 to +12 on the 2-3 shift did raise my best mph by 4.75mph though <img src="gr_stretch.gif" border="0">

Using the same weight as white53gmc (since I have never weighed my turck) the numbers were pretty much right on.

4250lbs-92.61mph-263.46hp

When your truck spinns off the line you are building up speed without gaining any distance. So its kinda like you are running farther that 1/4 mile.

It calculated quite a lot higher than my engines dynoed. About 33hp high on my Mustang and 55 high on my Camaro.
