Wow.
His "laundry" list just added over 1000 dollars to the base price tag.
Also the 100-200lbs of batteries alone is a ton. That will kill the car's time up to about 330' where the power from this setup can be used to it's full extent.
I won't even get into how this extra weight will affect handling & braking.
Great idea, so so results. Only truly good from a roll at WOT IMO and piss poor the rest of the time.
Hell if you want a drag car then buy one. This product is a lot of money for such a limited range of real world use.
For instance if a nitrous kit is $500. (I.E. drag oriented) How many refills in $2500???

(I.E. about 750 1/4 mile passes in a lighter car making more power for those not wanting to do the math)
