while i agree that the manual is more efficient, your numbers are bit off...a manual trans is not 15 to 20 percent more efficient based on whp...unless im unclear on what numbers youre using...ive seen an MTX car dyno 5-8 percent better based on bhp..but not 20%


and in the event of some cars, the auto is better for the track, especially older cars. old MTXs were crude and inefficient...ive seen someone take a high 12 second cuda, and swap in a 4 speed, and slow the car down quite a bit. while its more efficient than the 727, it isnt as fluid, and time is lost in shifting...hell, even the fastest LS1 based GM cars have automatics...i know a guy who has a built 02 camaro, and when he went from the mtx to a built atx, he went from 12.1s to 11.80s...
