My old engine dynoed at 667 horse, open headers, BIG twin carbs, radical cam, 12.5 to 1 compression. Never dynoed the new one, I estimate I gave up about 150 horse power, maybe more. Now based on your theory/ET calculations that horse power ALWAYS equals a known ET and Trap speed I guess 800 horse would put me in the 9's? Unless you were STILL running tires that won't hook up and gearing where you shift into fourth AT the finish line or stay in third and 'run it out the back door'. What ever horse power you got if you can't hook it up, ET calculations are worthless.
