Torque Monster !

My math was also 2740 in loc up with 33s. and 4.56s.
Here is the Formula;

mph= (rpm x Tc)/( R1 x R2 x1056 a constant)

Where the Rs are your gear ratios and
Tc is the Tire roll-out or; diameter x pi(3.1416)
The constant converts the numbers into mph.

Your TC slip will likely be larger than usual, in this case, because of the high torque input. IDK what it will be, but guessing 10 to 15%
