Way to measure HP?

.75 grams/sec.= 1 SAE HP when tuned *Precisely*
 calulated HP has never run a race.

Again, all about the state of tune.
If you were using a WB and knew that you were in the nieghbor hood of
12ish:1 then would be a fair guess, but why bother?.
Like I said calculated HP is an Ego issue.
Good for bench racing, and saying my dog is bigger then your dog.  that's
about all.
