10's on $5,000 ?

I've never dyno'd an engine. Never will. ET slip works for me. Only calculator I use is the 1320 divided by my MPH to let me know how well the car works. I mean, all the gurus said my stock 360 Duster with 2.45's, stock manifolds, stock converter was a 15 second car. It went 13.9s. I added 2.94's and headers and it goes 13.3's consistently. Yep, same as a factory 440 6 pack car with 4.10 Dana. Hmmm.

I think if you spent a day on the dyno, you'd change your mind. It's not different than a flow bench or any other tool.

It can show you things you'll never learn at the track. You can isolate things on the dyno you can't on the track. Most guys now can measure many things with onboard data logging, but you still add way too many variable to the equation.

I've seen many 600 HP engines ET like 500 HP engines and the dyno takes the blame when the chassis or converter or gear or all of them are the issue.
