Congrats on the new gearset
You have the knack for sure with that et
and
What little you've done to make more power
Of course ... the stick gives you options you
just wouldn't have with an auto
Will you dip into 13's
You could but you might not the first time out
because ..........
It very well could take you a trip or two to get
accustomed to how different it is gonna behave
Here is a tip that will take at least a tenth away
but
It takes a toll on the Ole Stang
The problem with DR's is they can do just so much
and
You got big honkin DR's at that and they are so heavy
and
Low profiled ... you get absolutely no sidewall flex
as opposed to
A REAL wrinkle wall slick
or even
A taller DR such as one on a light Prostar wheel
Not trying to say the DR's are bad
but
Saying they can't absorb driveline shock like slicks
anyway
If you feather the clutch a bit on the launch ....
Your sixty foot will fall for sure
but
You will shorten the life on your clutch
What you could do is try it for a few passes to get the
hang of the method.
Then get all conditions optimum like cool down and such
for a go for broke low et pass
and then
Don't Do It No More
Heres another
TRUE Power Shifting

Do I need to explain how it can effect your wimpy t-5
but
if done correctly ... you will gain at least a tenth
I myself ... wouldn't do it
Sounds like you are havin fun

Hope you break a 13
Good Luck!
