There is not too much debatable on this point.
Swamp, "we" keep talking from real life using a combination of
actual dyno charts input into CarTest, shift times from vBox
entered into CarTest etc., then simulating the results. We are
also talking our own Mexico runs that have the same results. So
far, the CarTest results perfectly match the real life results
we've seen. You haven't offered any simulations or any real-life
data other than stock cars in controlled environments with
professional drivers. When you double the horsepower, I'm telling
you that everything changes. I'm sure you're mulling over the
data posted above and looking for something wrong. It will be
interesting to see what you come up with.

BTW, I don't think the accepted science of trap speed isn't as
universally accepted as you think. I was at an NHRA drag race
last year and asked one of the top fuel drag racers this exact
question. At first he laughed and then added that everything from
shift speed to gear ratios affects the trap speed. So just to
satisfy my own curiosity, I ran CarTest simulations on a bone
stock DCT modifying nothing but the final drive ratio from 1.50 to
3.62. CarTest predicts a 7MPH trap speed difference between these
two ratios. How is this possible if gears don't make a difference
in trap speed?

We can start up this debate when DLSJ5 posts the vBox Racer video
of him racing Tightie's car.
