The Mustang has All Electronics DCM-231 motors and a steering wheel mounted "Nitrous Button" that activates a SPDT relay to put a hidden 6 volt battery into series with the original 12 volt battery.
We ran out of camera batteries and then the GPS wouldn't get a signal, but rough guess Wil was hitting 12 mph (stock is 5 mph).
If you have a newer Safety 1st 12 volt corvette, the motor swap will work, but you may have to rewire it to get much more speed out of it, because it has a control box that doesn't like mods. It's pretty easy to make a circuit that has multiple relays to lock out high speed reverse and take the big amps generated by higher speeds.
If you have a 1990's Power Wheels Corvette, they will take the mods with no issues.
I first thought, Friends don't let friends buy Mustangs But that's cool.
Looks like you'll have to be buying quite a few spare tires for that machine Bet they don't last long with him driving it.
Wished I was a little kid again with a Dad like you
Haha thats great. Give him a year and he wont fit anymore in those. When he is 16 post about how many tires he goes through and how many tickets he gets. Looks like a fun hobby!
