Way to measure HP?

[Bob Wooten]

Amen to that, I just came back from the track & double checked the numbers
that i got from the G-tech to the numbers that i got from the Data Master
to the numbers that i got from the timing lights @ the track.  they were
all close enough that i can confidently tune & test w/o having to goto the
track every time I want to check progress (or digress).  now if only there
was some way to not get those pesky "exhibition (sp) of speed" tickets when
warming up the meats.
