When you stand on the brake pedal and give throttle until the tires break is called brake stall and is meaningless. Flash stall is the figure that is the one that counts. That is when you nail the throttle from idle or just with enough throttle to load the drivetrain to launch without breaking something. Doing brake stalls may make for nice burnouts but is not healthy for the driveline. Find a very steep hill and with the car in 2nd gear goose the throttle, DO NOT FLOOR IT, just goose it hard and watch the tach and you will see the flash stall or close to it and it will be around 2600rpm's. Stock stall is NOT 1800-2000. Go to www.tccoa.com and do a search for stall speeds. That is a T-bird forum where Alan(dirtydOg) & Darrin(BC-Automotive) hand out. Alan is the mod of the drivetrain forum. You can send him a PM there and that is where a guy who works for Ford has the stall speeds listed. Do a google on how a converter works. Whe our converters lock it is like having a stick, no loss due to slippage. Still an auto will have 8% less power behind the same motor but it is consistant and does not miss shifts and can be made to be quicker than a stick. The Jan. issue of MM&FF has an article where the guys I mentioned changed a Bullitt with 600+whp to an auto. Mark
PS: Locking in 2nd gear. Our converters lock in 3rd and OD but do not go into OD at wot, not good. If you have an SCT tuner darrin can program the converter to lock after the 1-2 shift at WOT so you get no more slippage and thus even quicker et's. Check out the site I gave as they are much more educated on converters and the 4R70W tranny we have.
