Hey Dog, you, like I, agree that many a world record were set, many a high output motor got tuned, and TODAY, MANY competition engines get tuned WITHOUT a dyno everytime!
Guess there were NO powerfull engines prior to dynos!
Smokey, don't turn over in your grave.
Don't get me wrong, they used them, and they are a most valuable tool, BUT LIFE CAN GO ON WITHOUT ONE!
