Can someone post up as to it's accuracy from a recent run? It IS easy to use once you get the initial #'s plugged in. Kudos to the writer of this, it's a great spreadsheet!

Seems to work good. Shows me that I need to learn how to drive my car better though. Gave me a .4 lower et and about 4 mph more than I trap now with the same 2.3 60' time.

Crap, I just did heads/cam in Jan and got 376 rwhp and its saying I'm only trapping 108 something with a 2.0 60ft (which should be my 60 with my street tires). My goal was 110 traps, guess I just have to wait for spring and the track. Maybe I'm not using it correctly. Saying a 3750 weight with me in car.

Somebody asked for a comparison against real track times. How's this for ya -
Here's a breakdown from one of my real timeslips:
60' - 1.341
330' - 3.969
1/8 - 6.187 @ 110.91
1000' - 8.111
1/4 - 9.780 @ 133.66
Calculator times of the quickest possible:
60' - 1.341
330' - 3.920
1/8 - 6.163 @ 109.22
1000' - 8.115
1/4 - 9.785 @ 135.9

Great sheet! This goes way more in depth then anything I've seen before.
Possibly stupid question...the HP*0.85 estimate for if you don't have dynojet info. Is that a flywheel hp # you times by .85? If not, how would I estimate that cell given flywheel hp and say 20% drivetrian losses??
