I always wonder howa setup auto running a nice stall would do against a manual. I just finished reading a test in MM&FF Feb 07 page 140 excellant article first time I ever seen or read this type of comparison test. They took a low 12 second Mustangsetup with theC4 with a (8') 4700 rpm stall converter, deep pan, heavy duty servo, and transbrake then installed a Ford manual Tremec 5 spd and ran 1/4 mile runs. I not going to say the out come (no wars ) but if you get a chance it was aexcellant read!

lets just put it this way you cant beat the shift of a computer
even the fastest person in the world could not outshift a computer

yup...stalled autos and race trannies will outrun manuals. you just can never shift fast enough to outrun an auto...their weakness is the launch, but stalled that is gone.

I'll have to post the results, the car ranits best time with the manual the car always had an auto (setup TS-C4),best time was low 12's with the auto, with the manual car went high 11's. it also cut its best 60' ever at 1.54 with the manual. The car ran almost 3 tenths faster with the manual and +4 mphthan with the auto. They also went on to say they feel with a little work to the suspension they might get a little more out of the manual since it was setup for an auto and would make ajustments for the manual. This is the first time I ever seen or read a direct comparaison test, imo running 10's -9'sor slower Iwould gomanual 9's or faster I would go auto.

Ona side notethey alsodyno tested both setups they used an eddy-current dyno from Dyno Dynamic, these units have a reputation for delivering consistents results the dyno was loaded the same way for auto and manual the carproduced 27 more lb-ft with the manual than with the auto.

ya the power difference does have an effect the manual transfers the power to the ground better
but as far as strictly transmissions go a finly tuned auto can shift in .1 seconds
the fastest a human can is like .3 to .5 seconds but dont directly quote me on the numbers because they might not be just right but you get the point
