Auto vs Stick

If a car is going 10.80 at 124 with a stick what would be the et and mph with a auto? Any ideas, I know that there is some factors to consider but if you took the stick out and put in a quality auto what would the difference be?

It depends more on the abilities of the manual driver than the switch of transmissions.

It depends on how much your converter is slipping if everything is equal,like rear end gear ,tire size and abilities of the manual driver.

Well, you will probably lose some manly hood as well as a couple MPH with switching to a slush pump-I mean automatic... lol

It depends a great deal on the combination.

In addition to overall combination, some automatics are more efficent than others. In my bracket car, with a mild 428FE Ford engine, and a fairly good C6 (low drag Torrington bearings thru out, Art Carr trans brake, 8" converter etc) the best the car went with the C6 was 10.55ET @126 MPH. With no other changes, other than replacing the C6 with a 4 speed Jerico & McLeod Soft Lok clutch, the car has gone a best of 10.03@132mph.

Just to show how wide a range this question encompasses I race the same track as Rory and went the opposite direction, 14.00 with a stick and 12.80 with a auto. It all depends on the combination.

ET will vary because there are so many variables. But MPH should almost always be better with a stick.
Remember, MPH is based off HP. ET is everything else that is involved with getting you from point A to point B.
