Wow thanks didnt know that Can ya tell I still need to make a trip to the track?

 

My experience with my car. If I hook it the MPH is always higher. If I spin, the MPH is low. Example... my best MPH to date was also with my best 60'. I was (sorta still am) having traction problems. The car will still trap 1-2 MPH lower than if I really hook it.

1.6x 60' = 112+ trap speeds

1.7x 60' or worse 99.9% of the time it will trap below 112 MPH. I have seen as low as 109 with a really bad 2.0 60' and the same day hook it with a 1.62 and trap 112.7MPH.

Every car is different depending on where you make your power. But as a general rule the i agree with the other guys. 22-27 mph gain in the last 1/8.

 

even with what has been said..i still believe a lower 60' will give you a higher MPH.

the way i see it is if you spin out of the hole maybe good for a 2.5 sec. 60' now just because a guys tires are spinning at the rate that would normally move the car at 60 mph doesnt mean when his tires finally bite in that his car will instantly be going 60 mph because your RPMs drop. so if your tires are spinning at 60 mph are you are only creeping forward at 15 mph then you cant possibly hit 60 before first dropping back down to 15. this kills ET and should hurt MPH too.

an analogy that works for me is running a foot race. lets say that one guy gets one of those pedistals(slicks) they use in track races and the guy next to him has to start in loose gravel(street tires). the way those pedistals are engineered, should make a runner actually launch off the line as opposed to starting out on a flat track. the guy in the gravel will obviously slip a little on the start if he tries too hard to punch forward infront of his opponent. now about a second into the race...the guy in the gravel will be noticably in 2nd place because it takes him more time to build speed and momentum off the line. the guy in the lead got instant momentum off his pedistal because he launched off the line which builds speed easier and faster than starting in a natural position. so not only is the 2nd place guy behind the 1st place guy but at the same point on the track, he is actually moving slower than what the 1st place runner was which results in a slower run and slower speed at the finishline.

 

All cars work differently. One theory will not hold true for all. I was just stating my experiences.

My posts of my timeslips in a previous post was just my experience.
