What do ya think
 

I was wondering what the diffrence in e.t. between a AOD / T-5. In a completely stock mustang GT.

Potential, or likely?

If the stick driver was just plain awesome, close to a full second. Normally, about 1/2sec or so. The stick car is much more open to mods, but once some money is spent on the AOD, it's not too shabby.

T-5 vs AOD et
 

When new and being tested, generally the stock 5.0/ AOD ran low 15's and the stock 5.0/T-5 ran mid 14's in the quarter-mile.

The actual et difference can be anywhere from a few tenths to a full second depending on the stick driver's skill. Average difference: about a half-second lower et for the T-5, assuming both cars were stock.
