2 different dynos,2 very different numbers.why?

And in some cases, a builder will use inflated numbers as a "sales tool" ....There WAS a well known builder right on this site who I think used that technique, he always made huge power numbers, and all of fabo would oooooooo, and ahhhhhhhh, about his magic, but EVERY one of those builds if ran at the track, would MPH light years off the claimed HP.. Same thing happens with head porters and flow benches. Big numbers SELL


I asked many times for this builder to post time slips, he never did.

As far as dyno's go they are a tool, just like a timing light or a vacuum gauge. If a person don't see the value in using one they probably will never build anything that needs to be on one.
