He is running a Tremec TKO 600 so the 3rd gear ratio is 1.28:1
That would mean he has to have 2.30 rear end gears to make 138 at 5K!
I noticed on the burnouts that it is an open rear end. (One stripe)

I'm still interested in the cost of the electric over the gas. Looks like it's gonna cost about 25K min for the motor batteries and controller!
