The Grind Hard Plumbing Co built this thing out of a Barbie Mustang and an old go kart. Now, it tops out around 70 mph!

The YouTube channel for the Grind Hard Plumbing Co says they build crazy contraptions and cars. Well, it appears that this is exactly what's happening here. So far, so good.

What kind of engine is in that Barbie car? Honda 240cc single cylinder air cooled 4 stroke engine from a Honda CRF 230 dirt bike. Built with a performance cam and big bore kit.

Here's how they explain how they built it:

We built this Barbie Mustang Go Kart in four days. First I found a used and abused go kart on craigslist and we got that running. Then we tore apart the Pink Power Wheels Mustang, cut the go kart chassis to fit in the toy car then pulled the motorcycle engine. We welded engine mounts in the front of the kart for better weight distribution then installed a 240cc Honda Dirtbike engine.

I think they actually plan on racing this thing against a team that built a shopping go kart.
